The calculation method for the amount of electricity required for charging new energy vehicles is as follows:
1. Determine the battery capacity of the battery pack: Lithium battery pack capacity=rated voltage of the battery pack x capacity of the battery pack.
2. Understanding charging efficiency: Due to the existence of charging efficiency, there may be some losses during the actual charging process, so the actual charging degree may be slightly higher than the battery pack capacity. In general, the charging efficiency is between 90% and 95%, depending on the charging equipment and battery status.
3. Calculate the required charging degree: Required charging degree=Lithium battery pack capacity/1000 ÷ Charging efficiency. For example, if the battery pack has a capacity of 720WH and a charging efficiency of 90%, the required charging degree is: 720WH/1000 ÷ 0.9=0.8 degrees.
Note that the above calculation method is an estimation under ideal conditions, and the actual charging degree may vary due to various factors such as charging equipment, battery status, and ambient temperature.
