The battery of a battery car generally has a voltage of 36 volts and a capacity of 12 ampere hours. The battery power is 36 volts * 12 amps = 432 watts. The motor power of the battery car is 180 watts, 240 watts, 350 watts, etc.; charging time is 6 hours per hour. The charging current is 2 amperes, and the charging capacity per hour is 36 volts * 2 amperes * 1
Hour=72 watt-hour=0.072 kWh=0.07 kWh, 6 hours share 0.07 kWh*6=0.42 kWh, if adding the 20% loss of the charger, it takes 0.6 kWh to charge once. Because the charging current is different, the charging time is different, but the total charging power consumption is about 0.6 degrees!
