1. A charging method for a lithium ion secondary battery which comprises a positive electrode including a positive electrode active material capable of absorbing and releasing lithium ions, a negative electrode including a negative electrode active material being an alloy-formable active material capable of absorbing and releasing lithium ions, a separator interposed between the positive electrode and the negative electrode, and a non-aqueous electrolyte,the method comprising the steps of:

  • detecting a remaining capacity and a temperature of the lithium ion secondary battery; and

    charging the lithium ion secondary battery until a battery voltage reaches a reference voltage E1 associated beforehand with the remaining capacity and the temperature.
