摘要
When charging of a battery is started, a voltage of each module being charged is detected, and then an average voltage and at least one of a maximum voltage and a minimum voltage of the modules are calculated. Subsequently, if an absolute value of a difference between the average voltage and at least one of the maximum and the minimum voltages is greater than a predetermined reference value, it is determined that the battery may be malfunctioning. If it is determined that the battery may be malfunctioning, a charging mode is changed to a safer mode and a warning of the possible malfunction is given.
