Hello! Theoretically, the battery can store 22 degrees of electricity, which refers to the maximum energy storage.
KWh is the standard unit of electricity, which is what we usually call degree. In addition, ah unit is used to represent the battery capacity. Generally, ah ampere hour unit is used for comparison when the voltage is the same. After all, it is intuitive. For example, most mobile phone batteries use ampere hour as the unit of electricity. It mainly depends on the battery capacity configured by the electric vehicle, and then depends on the remaining amount of battery power before charging. Generally, it is assumed that it is calculated from the lack of battery power, that is, it is related to the battery capacity. For example, if a car is equipped with a lithium battery capacity of 22kwh, the theoretical charging capacity is 22 kwh.
