How long should a new 72V battery be charged for the first time?

[AlyssaLee]

For the first charge of a 72V electric vehicle, it is recommended to charge it for 8 hours according to the manufacturer's advice, until the battery is fully charged. Range of a 72V electric vehicle: Taking a 72V24Ah battery with an 800W motor and an average speed of 45km/h as an example, the average current at constant speed is 11.1A (motor power/voltage), the theoretical driving time is 2.16h (battery capacity/average current), and the theoretical range is about 97 kilometers (theoretical driving time × average speed). Extending charging frequency: If the daily power consumption of the electric vehicle is not much, only about 10%, you can consider extending the charging frequency, such as charging once a week. When the daily power consumption is 20%-30%, you can consider charging every two or three days. If the daily power consumption is 40% or more, it is recommended to charge once a day, controlled at about 5-6 hours.
