Electric Vehicle Charging at Home Typically Draws Less Than Half the Power of an Electric Furnace

From Enegy.Gov

Electric vehicles can be charged at power draws comparable to various household appliances. Most electric vehicles charging at home on a 240-volt level 2 charger will draw about 7,200 watts or less. For comparison, a typical electric furnace draws about 10,000 watts and a water heater uses 4,500 watts. The power draw for an electric vehicle is limited by either the electric vehicle supply equipment (EVSE) or the vehicle’s onboard charger which limits the rate of electricity the vehicle can accept. Many first-generation plug-in vehicles have onboard chargers limited to 3,600 watts, similar to the power draw for a typical home air conditioning system, while newer electric vehicles have increased onboard charging rates. Some owners use only a standard 120-volt household outlet (level 1 charging) which has a very slow charge rate and low power draw compared to the level 2 charging. There are some electric vehicles, such as those produced by Tesla, that allow for even greater home charging speeds and higher power draws similar to an electric furnace. While an electric vehicle can draw a considerable amount of electricity when charging, the overall fuel cost for an electric vehicle is lower than a comparable gasoline vehicle.
