The power consumption of electric vehicle batteries is directly related to their capacity.
Assuming the standard capacity of a 48V electric vehicle battery is 20Ah, the total energy of the battery is 960Wh.
1 kWh equals 1000Wh, so 960Wh equals 0.96 kWh. A 48V 20Ah electric vehicle battery requires approximately 0.96 kWh to fully charge.
