Abstract: A method for charging aluminum batteries includes performing a first charging procedure for the aluminum battery until the voltage of the aluminum battery reaches a set value. The first charging procedure at least includes a first constant-current charging using a first constant current to charge an aluminum battery in a first stage. The range of the first constant current is from 5 C to 100 C, and C (C-rate) refers to a unit of the capacity of the aluminum battery. When the voltage of the aluminum battery reaches the set value, a first constant-voltage charging uses a first constant voltage to charge the aluminum battery. According to the charging current provided by the first constant voltage to the aluminum battery or the charge time for the aluminum battery charged by the first constant voltage, a determination is made to stop the charging process on the aluminum battery.
