Abstract
The present application relates to a battery charging method. The method comprises the steps of: in accordance to the current's adverse effect on battery lifespan, classifying the charging current of a battery into a first type of charging current and a second type of charging current; setting a proportion limit on the first type of charging current and a proportion limit on the second type of charging current; obtaining the historical charging current information of the battery; determining the historical accumulative proportion of the second type of charging current in accordance to the historical charging current information; in accordance to the proportion limits and the historical accumulative proportion, determining the type of battery charging current which is present available. By taking into account different charging currents' adverse effect on battery lifespan, the charging method solves the problem of excessive charging current's adverse effect on battery lifespan.
