How Much Electricity Is Required To Charge An Electric Car. The rate of charge can vary from 25kW to 350kW DC allowing you to charge your EV from low. Instead an electric cars energy consumption is measured in kilowatt-hours per 100 miles kWh100 miles.
Based on our estimates the charging requirements for a fully electrified fleet of personal cars in Texas would be about 290 gigawatt-hours per day less than the available surplus of. The average electric vehicle needs 33 kilowatt-hours of energy to travel 100 miles 160 km. Assuming power stations have a 40 conversion efficiency fuel to electricity then you need extra capacity of 54 GW to charge all these cars.
Though electric cars are greener than conventional ones much of their power still comes from coal.
So divide the total miles you drive each month by 3 to get the kWh you would use monthly. However the typical electric vehicle offers a standard 60 kW charger which would more than double that cars charging time. Charging an EV at 40 A 96 kW means it will take a little more than one hour to charge to the minimum required daily amount compared to 1 hour and 20 minutes at 30 A 72 kW. A conservative rule of thumb is that an electric car gets 3 to 4 miles per kWh Voelcker says.
