Abstract:
In a charging method for a lithium ion battery, constant current charging of the lithium ion battery is performed. The constant current charging includes at least three consecutive charging stages. The at least three consecutive charging stages include consecutive first, second, and third charging stages. The second charging stage has a set current value which is set lower than set current values of the first and third charging stages.
