摘要

A charging control method for a non-aqueous electrolyte secondary cell is a charging control method for controlling a state of charge of a non-aqueous electrolyte secondary cell that has a non-aqueous electrolyte between electrodes, a target state of charge serving as a target for stopping charging is preset in correspondence with an ambient temperature of the non-aqueous electrolyte secondary cell, and the target state of charge (e.g., 95%) for when the ambient temperature is a specific temperature (e.g., 25° C. or 20° C. to 30° C.) that has been specified in advance is set higher compared to the target state of charge for a temperature other than the specific temperature.
