How Many Amps Does A Car Charger Draw. Generally a car battery pulls approximately 400 amps for small vehicles to start and more than 1000 amps for the large ones. If you do decide to go with a plug-in charger for now just be sure your 240V circuit is rated for 50 amps.
My car battery charger might has a 2amp slow setting or a 10amp fast setting. 72 amp version comes with the 100kWh battery cars To take full advantage of either one youll need a Tesla Wall Connector attached to either a 60 or 90 amp circuit respectively. It will charge in about 3 hours with a 30 amp Level 2 EVSE vs 6 hours with a 16-amp station.
The amps in the car battery should always remain close to 0000 to prevent it from damaging.
A gasoline car would probably have similar draws. Power output of 21 amps but a no load power draw of 35 milliamps. Even if your home charge point is capable of charging at 22kW the I-PACE can only charge at 74kW. Charging at 172 kW of power on a 240 volt circuit may require a home electrical panel upgrade to 400-amp service.
