Title: BATTERY CHARGING METHOD
Abstract:
Disclosed is a battery charging method, which aims to solve the problem of the service life of a power battery being affected due to an excessive current when the power battery of an electric vehicle is charged by a battery-charging and battery-swapping device, especially a battery-swapping station. The method comprises the following steps: according to effects of the magnitude of a current on the service life of a battery, dividing charging currents for the battery into a first type of charging current and a second type of charging current (S110); distributing usage limitation proportions to the first type of charging current and the second type of charging current (S120); acquiring historical charging current information about the battery; determining a historical accumulation proportion of the second type of charging current according to the historical charging current information (S130); and according to the usage limitation proportions and the historical accumulation proportion, determining a current available charging current of the battery (S140). Since the effects of different charging currents on the service life of a battery are taken into consideration, the charging method solves the problem of the service life of the battery being affected due to an excessive charging current when the battery is charged.
