Electric vehicles (EVs) use a DC-to-DC converter to step down the voltage to 12 volts, allowing them to power all auxiliary systems without passing the current through the 12-volt battery. This allows for efficient energy transfer and improved performance. The difference between a watt and a volt in EV charging is that a watt is like water pressure, pushing an electrical current to the battery. Most battery-electric vehicles (BEVs) can accept between 40 to 48-amps while charging from a level 2, 240-volt source.
Level 3 charging uses direct current (DC) to charge a vehicle’s battery directly, instead of the alternating current (AC) used by Level 1 and 2 charging stations. Direct current fast chargers are common as public chargers and along highway corridors and can charge a BEV to 80 percent in under an hour. A home EV charger would use around 11.81 kWh per day to charge the car to replenish the range driven.
A level 1 charger requires 120VAC (in the US), while a level 2 charger requires 240VAC. A DC charger converts power from AC to DC, allowing direct current to flow straight into the battery. EVs typically operate at higher voltages, ranging from 400 to 800 volts, which allows for efficient energy transfer and improved performance. The peak discharge rate may reach 2C or more, which is converted into a current of approximately -300A.
The SI unit of electric current is represented by the symbol A. Ampere-hour (Ah).

Does Tesla use 800v?
Tesla Cybertruck will begin deliveries on November 30 with an 800-volt architecture, a move that has been confirmed by the company in its earnings call earlier this week. This is a significant move for the EV industry, as more electric cars are on the road, charging times are a concern, and heavier all-electric cars are becoming more available. Tesla confirmed that the Cybertruck will be equipped with an 800-volt architecture, a significant development in the future of the EV industry.
Is 200-amp enough for electric car?
If your home has a 200-amp panel, you don’t need to upgrade it before installing an EV charger, except if it’s already operating at or near its capacity. This is only true if your home has a higher power demand. For homes with 100-amp panels, an electrical panel upgrade may be necessary. These panels were standard for decades but are generally insufficient for modern lifestyles. Alternative options for homes with 100-amp panels include a Load Management Unit (DCC-10) or a Transfer Switch, which can allow for an EV charging station installation.
Is 100-amp enough for EV?
The article provides a checklist to avoid blown fuse while EV charging. It suggests that if your home has a 100-amp panel, you should upgrade to a 200-amp panel before using a Level 2 EV charger. If your panel already has a 200-amp panel, you can plug it in yourself. If you have a high enough voltage, the grid should deliver the 240V power you need for an EV charger.
To avoid paying for unnecessary electrical work, it is recommended to get a free quote from a trusted electrician and shop around to ensure they understand your specific needs. It is also important to be aware of unnecessary permits, as Level 2 chargers can be hardwired to your panel or plugged in to a 240V outlet. Hardwiring is typically only required for outdoor charger installation, while indoor charging is ideal.
Lastly, it is crucial to check if the quote includes permits, as some installers may not cover these costs. It is also important to know whether the installer will handle the permitting process for you.
In summary, the article provides a checklist to avoid blown fuse while EV charging and provides tips on how to avoid unnecessary electrical work.
How much current does an electric car draw when charging?
Electric cars at home typically use 7, 200 watts of electricity, depending on the mode and home charger. Most chargers use between 32 and 40 amps and connect to a 240-volt outlet in your home’s breaker box. Electric car charging at home can lead to a spike in monthly electricity consumption, but it’s important to understand the specific wattage of different chargers. Solar panels can save money on electricity costs, and it’s essential to research the cost of solar panels in your area in 2024.
How much current does an EV draw when charging?
Electric cars at home use 7, 200 watts of electricity, depending on the mode and home charger. Most chargers use 32-40 amps and connect to a 240-volt outlet in the home’s breaker box. The amount of driving your EV impacts the electricity used to charge over time. Americans drive 14, 000 miles per year, consuming an average of 0. 35 kWh per mile driven. With a level 2 home EV charger, this amounts to 13. 4 kWh of electricity daily.
How many kW is 800v?
The transition to 800 volts requires charging equipment that can utilize this architecture. Most level 3 chargers operate on 400-volt systems, delivering 50-150 kW. 800-volt chargers, which can deliver up to 350 kW, are not widely used. Ionity, Tritium, and Electrify America are the major players offering 350-kW and 150-kW chargers in convenient locations. The roll-out of 800-volt systems and charging infrastructure will occur rapidly, as the convenience of super-fast charging will be irresistible to future EV owners.
What is the minimum charging current EV?
The IEC 61851-1 standard, a communication protocol between electric vehicles (EVs) and charging stations, has limitations, requiring a minimum charging current of 6 A before an EV can start charging. This is a significant power consumption for a PV installation, which cannot be changed. To optimize solar consumption, smart charging schedules can be used, which optimize solar production consumption throughout the day and import additional power from the grid if necessary.
However, this method does not allow additional solar production to flow into the vehicle once the charging schedule has finished. Additionally, the Smappee app allows users to reduce the minimum surplus percentage necessary to start charging, such as setting it to 50, allowing charging to start when there is a surplus of 690 W (single-phase) or 2070 W (three-phase).
How many amps does an EV car use?
Electric car charging requires varying amps, with most vehicles capable of using 32 and 40 amps. Having an adjustable charger that can match future needs offers long-term savings and convenience. Consult your vehicle’s manual to determine the exact number of amps your vehicle can accept. If upgrading your home’s EV charging station, consider the Home 50 unit, which offers fast, reliable charging, Wi-Fi capabilities, and mobile app integration. Learn more about the latest EVSE.
How much current does an electric car need?
The average electric car (EV) consumes 34. 6 kWh per 100 miles, equivalent to 0. 346 kWh per mile. Factors determining the range of an E. V include battery capacity, wind, temperature, driving style, air conditioning usage, tire condition, carload and topography, and road conditions. An American E. V consumes 30kWh/100 miles, and using the US Department of Transportation’s average annual miles driven by American drivers, we can calculate the monthly electricity usage.
Why is 800V better than 400V?
The 400V and 800V architectures are crucial factors to consider when choosing an electric vehicle (EV). The 400V architecture offers higher efficiency due to reduced current for the same power output, resulting in lower resistive losses. This makes it ideal for high-power applications, making it ideal for high-performance EVs. The architecture used to manufacture an EV, including battery types, capacity, and placement of electric motors, also plays a significant role in the overall performance of the vehicle. This guide provides a comprehensive understanding of the pros, cons, and differences between these architectures.
How much current is needed to charge an EV?
A 3. 6kW EV charger requires 16 amps, requiring a circuit breaker rated for 20 amps. A 7. 4kW charger requires 32 amps, requiring a circuit breaker rated for 40 amps. To determine if your home has enough power for an EV charger, a qualified electrician must calculate the property’s maximum demand, which is the peak electricity demand from the grid. If the maximum demand exceeds the incoming supply, a fuse upgrade may be needed. Most homes have 80 or 60 amps, more common in older or smaller properties.
📹 How Do Electric Vehicles Work?
Ever wondered how EVs get from A to B? Is it essentially the same as an internal combustion car, but wired up to a giant battery?
Norway is closing in on a 80% EV market share at the moment. The last couple of months 70% of all new cars has been electric, and this number is steadily increasing every month. Wouldn’t surprise me if we have 90%+ by the end of next year. With long distances being a thing in Norway, short range EV’s are only usable in the cities, but with increasing capacities of up to and above 600 km in one charge, the sales of EV’s are skyrocketing. I’m still one of those with an old combustion engine though, but next year … 😉
Just a simple question, isn’t it true that the accelerator pedal/gear box performs exactly the function of dosing speed, torque and power in a gasoline engine. If this is not true then, I must have performed a miracle every day I drove my gasoline car for the last 50 years or so. Over representation of electric car does not serve the cause of electric cars.

As usual excellent article ! Thank you very much and may God bless you always ! No ! For a while I will not be buying an electric vehicle. I will wait until batteries have a more extended range. Toyota just announced they are working on a battery that will have a range of 1000 Km ! If they can make it, then I would buy one electric pick up truck or an electric Hummer !
Excellent short article. But I am still a fan of ye olde combustion engine. Just for the take off. AND towing capacity. I don’t see an EV winning a take off race from a standstill against an 8 cylinder engine. And sure EVs are great for confining your people to cities (the range of one charge), but what about the people who WANT to drive all around the continent, or tow heavy things like boats/caravans/other cars. Or live in the middle of nowhere and improvise their own fuel. Currently, I’m still seeing those cars constantly plugged in, or getting a charge from a generator brought to them by an oil fueled car.
To be honest a gear box/transmission would not only increase the power of the electric motors but also the rang and battery health, Henry Ford noticed this about his cars, he had an engine with base power and rang but he realized by utilizing a gearbox/transmission he could double its power and fuel efficiency and engine life, the same can be said about electric motors, sure they might have more power on there own without the gear box but they gear box would take wear and tear off the ev motors and make the batteries go much further
If two same motors were connected to a battery and if the battery spins the motor and the other motor that’s connected to it generating electricity to charge the battery the same amount the other motor is using from the battery, and the motor that’s using power from the battery was connected to the wheels, would it run infinite?
I agree with Tesla EV’s however they use a “SINGLE SPEED GEARING TO DRIVE THE WHEELS” My gearing system uses a tooth difference of “ONE” tooth between Gear & Pinion. Resulting in many advantages of wt. & size of tooth, with arc of contact of 120 degrees. Simplicity & lower cost of manufacture & can develop much higher RPM’S.
I think people overstate the EV’s “environment saving” sales pitch. I’d want an EV but not for environmental awareness. Simply because the absolute vast majority of power that sustains us is of Coal plants. Meaning there is little effect to whatever climate change you believe in. As, believe it or not, combustion vehicles don’t actually contribute a whole lot. EVs still have a lot of problems like charging and battery capacity. If we discover a new form of battery to replace the ancient lithium ion battery then we will be great. As it stands though, EVs consume quite a bit of power too when compared to normal vehicles. The Tesla Semi apparently advertised that it’s battery would be able to hold a Megawatt of energy, I don’t know if you know this but a Megawatt of energy for 1 vehicle is a ridiculous amount of energy, The average Nuclear Plant produces 1 gigawatt of energy (1 billion watts), a gigawatt is 1000 megawatts and a megawatt is 1 million watts which is 1000 kilowatts etc, Could you imagine an entire fleet of Tesla Semis using a megawatt of energy each. And you can’t expect “sustainable” energy sources to keep up. Because the amount of space needed to create just a megawatt of energy in Solar or Wind power is astronomical compared to Coal or Nuclear power, which is why I think both “sustainable” energies are a waste of resources and time. Solar is only really practical on a homeowner basis, but to supply an entire power grid is ridiculous as you’d need to fill the entirety of Africa with Solar in order to compete with the power output of 1 Nuclear plant.
The only problem is that Electric Cars are so expensive even the cheapest Tesla is 58k not before you have to have the recharger all hooked up in your house so you can actually charge it and that will cost you another 11k to have set up and most peoples houses are so old they cant be installed. So in total if you want to go eco friendly you have to spend almost 70k and about 30% of the general population cant afford a Tesla and about another 15% cant even support a Tesla in their home. Everyone wants to talk about how going green is so great but never about the costs.
The only electric vehicle I will drive is an Electric bike. Not an motorcycle but, an bicycle that had and electric motor to assist me while riding. This is known as an E-bike. This bike is equiped with torque sensor. And a rotation sensor. This sensor checks if I turn the cranks. IThe torque sensor will measure tha amount of force on the cranks and calculate how much power it needs to use assisting me. And I can choose how much it’s helping me. From 70% up to 200%.
Are electric cars more efficient? Running a gasoline car involves: Burning gas in the internal combustion engine and converting thermal energy to mechanical energy. That’s it. Charging an electric car’s battery from the grid and driving the car involves: Burning gas at the power station and converting thermal energy of gas to mechanical energy of the gas turbine. This is only moderately more efficient in a power station than gasoline cars. Then, losses begin: Converting the mechanical energy of the turbine into electrical energy in the generator involves generator losses Converting medium voltage from the generator into high transmission voltage involves transformer losses Transmitting the power along the high voltage lines involves transmission losses Stepping down the voltage in several substations involves transformer losses again In a home charging station, converting 220v power into DC for car charging again involves conversion losses A chemical process in the battery being charged heats the battery, involving charging losses Running the car’s electrical motors from the battery requires inverter losses to generate electricity for traction motors and motor losses. Take a look at what happens when a driver needs heat in the cab: Heating a gasoline car in winter involves redirecting waste heat (hot antifreeze) from the engine into the cab heater, thus not requiring additional fuel. Heating an electric car requires a resistance heater or a heat pump, needing to eventually consume more energy from the grid – with all the above conversion losses included.
Sounds like combustion piston engines can be achieved without fossil fuels because kinetic energy can make friction heat and air burst intake devices do exist, as there was one famously featured on sharktank some years back…but it would probably be great for hybrid electric vehicles to have that…Very much wondering from this, instead of larger, more capacity batteries, maybe a smaller electric motor drives larger motor to drive the car…while smaller batteries recharge with mechanical features so as to avoid charging station needs until battery replacement necessary… Just very much feels like mechanical designs should be engineered to work synergistically with physics in order to optimize existing battery chemistry, but it does not seem like that’s happening…Mechanical engineering only adds drag if defying physics and ignoring chemistry…but that should not be the state of modern technology which has grasp of all those sciences and more, if biochemistry is factored….Plus Quantum etc…
it possible to make electric cars and two electric cars with a cylinder larger than 300 vehicle speed, knowing that I am the electricity in the machine, generating power with its safety parts, and the battery costs a lot to charge. Thank you. If you have the satisfactory answer, write so that I can translate it into Arabic.
There is no such thing as a Zero Emission Vehicle. The real question is, where are the emissions associated with the electric car? Because what you do with an electric vehicle is you don’t eliminate emission, you export them somewhere else. You have to dig up 500,000 LBS of materials to make a single 1000 LB battery. It takes 100-300 barrels of oil to manufacture a battery that can hold 1 barrel of oil equivalent of energy. Just manufacturing the battery can have a carbon debt rate ranging from 10 tons to 40 tons of CO2. And the plans that are in place to increase the use of batteries will require an increase in production of minerals like lithium, cobalt, zinc. Demand for those minerals will increase between 400% and 4000%. There isn’t enough mining in the world to make enough batteries for that many people for their cars.
I bought a electric car ! I hated coming home on Friday after work family ready to go to the lake ! BUT we have to wait till mourning for car to charge AGAIN !! Then we were sitting in truck stop 3 hours later sat there for 5 hour’s AGAIN only to do this AGAIN just to make it HOME !! I junked it went back to gas vehicle ..now we can go forever !! DON’T fall for electric cars ..
If electric vehicles weren’t full of electronic items, then they would be able to go a lot further than what they do. Sadly though, vehicle manufacturers have bought out electric vehicles, before they’ve sorted out all the problems with them, like charging time and traveling distance, as well as moving the vehicle if it runs out of electric and the fact that when they catch fire, it takes more than 24 hours to make it safe and they also have to spend that time completely submerged in water.
EV’s are still not a great option. Until they come up with a way to power themselves and not have to plug into a grid, there will be problems. The ones who are really pushing these are the power companies. Good luck when you have a storm that knocks out power for a period of time. It will happen and everything will come to a stand still because you can’t recharge.
Charging time, the distance the cars can go, and cost. EV’s will never be mainstream in places with large travel distances until these issues improve. 643 miles from Amarillo Texas to Corpus Christie Texas and that’s just within One state! New York to Atlanta. 850. Produce a decent-looking car for under 30 thousand that will go 500 miles at the bottom end range. Produce charging stations that are not sabotaged and blocked and can charge in the same amount of time I can gas up my car. And, I don’t get panhandled or mugged.
As long as EV battery raw material mining is full of pollution, dirty electrical energy sources(even the so called renewable energy leaves a lot of carbon footprint and waste), power efficiency power loss along power grid to charging battery, extra load on the car, long charging time.. Of course my car is going to be ICE or hybrid.
There should be a simple battery design where portable batteries can be removed from battery capsules or pods just like Nimbus One three-wheeled car and then placed back into these pods/ capsules once charged. I imagine a dozen of these battery pods in an electric car, let’s say 6 battery pods in the front bonnet section and the other 6 battery pods in the boot of the car to maintain weight balance. Easy inexpensive battery service if one of these batteries become faulty /*
Nope, they have to many deaths attached and are not as clean as a gas powered car. Where is the majority of electricity coming from? Coal and oil. Not burned as clean as in a normal gas powered car either. We simply lack the technical resources at the moment. California is a perfect example. Now they are having issues keeping up the demand for electricity so there’s that as well. Too many issues between both. Plus, I am sure people have used Rechargeable batteries before. There is an issue as well with how many times something can be recharged before being useless. What do we do with the waste produced from dead batteries that will no longer charge? How much does it cost to replace one in an electric car? As for now I believe them to be inefficient, irresponsible, and irrelevant until we have studied more and just because we can doesn’t mean we always should. I have too many issues as of now, when they are fixed I might revisit the discussion. Cobalt is another issue. Remember how Nike made profits in the 90s? Guess how cobalt is mined these days. Oh, did you think the United States were going to use any of our own resources? Nope, might want to look at that one again🤣🤣🤣. I enjoy my time here lol
But do these companies not all buy most of the batteries and other essential parts for EVs from the same manufacturers? Because EV companies don’t design their own electric batteries etc. So apart from the shell and interior being different, what makes any of these cars stand out from their competitors when they are buying off the shelf electric parts? Surely petrol heads bought cars from a specific brand, because they had all developed their engines differently, had different horse power, different power settings, different sounds, they has unique engine features, they looked different etc, etc. You may as well have a milk float for all the difference these “luxury” cars will be from each other at the base level. It’s business suicide for any company that falls in line with this agenda. Not to mention there’s not enough precious metals on the planet to sustain this. Strip mining whole areas, cutting down large areas of trees to put wind farms up and large, rare birds of prey dying due to wind turbines compared to a bore whole in the ground, taking up very little space. I know in reality which has the least impact on the environment. But EVs aren’t charged using purely wind and solar power are they, so not really green. Nothing says I support child slavery like an EV.
So all of yous out there with those expensive electric cars, how are your cars doing with those of you living in places where temperatures are dipping down to 0 and below? They dont tell yous that EVs don’t do well in extream temperatures. Maintenance is costly too. Oh what, they didn’t tell yal that either? If you should ever need to replace them batteries, you better get a loan because it will cost you between 7 and 12 thousand dollars. Go ahead and take the 20 to 30 plus minutes to fully recharge. I have a Buick Lacrosse and a Nissan pathfinder rock creek and both of them are paid off. Takes me 2 minutes to refuel. This country is so damn gong ho on Technology that they forget that sometimes old school is the best school. Technology? But the mighty United States of America can put people in space but still can’t do highspeed rail? What a joke! I love electric cars, they just have to perfect them before i even think about spending the money to get one. Come out with one that takes 10 minutes to fully recharge. Come out with one that can withstand extream temperatures and that is inexpensive. Then, i will think about it…
I forgot to charge my vehicle 🚗. Sorry boss I’m going to be 4 hours late. Why? I have to wait until my battery charge. How many miles to empty? It’s 250 miles to empty however if I turn the A/C on and the Radio, Navigation, and Lights, I get around 80 Miles a charge. That doesn’t count the cold weather destroying my electric battery. I’m having fun going nowhere🍷
I don’t know how our IQ is so low. What is environmentally friendly about all this electric cars? How are the car parts made, I mean the process? Secondly how do they source for the raw materials used to make the batteries. Go and look at the environmental degradations caused in Africa where they get the raw materials used for the battery (Democratic Republic Of Congo) especially.
So why did tesla use its own tesla plug in america 🇺🇸 and not allow other EV s to use his charging hubs. Euro teslas where built right and have CCS . Damage is already done reason everyone hates tesla. Euros and american EV drivers all hate teslas and will never buy one. We would way rather have the Porsche EV that is quality and fast any day over a ugly tesla that looks like a wannabe mercedes fast but NO quality The tesla roadster is the only one that looks good but you never see them only all the ugly ones.💩💩💩💩💩💩💩💩💩💩 Careful getting in. the tesla if you slam the door to hard all the doors fall off. Lol 😂 😂😂😂 Emergency exit plan 😂😂💩💩💩💩💩😂😂 uneven gaps dust storm paint jobs. Lol 😂 😂😂😂😂💩💩💩💩💩💩😂😂😂💩 Getting a good tesla is like picking a winning lotto ticket 😂😂😂💩💩💩😂😂😂💩
