摘要： In the present method, a non-aqueous electrolyte secondary battery is charged by repeating n+1 times a constant current charge and a subsequent constant voltage charge, where n is an integer of 1 or more. (1) An nth charge comprises charging the secondary battery at a current Ic(n) to a voltage Ec(n), and subsequently charging the secondary battery at the voltage Ec(n) until the current decreases from Ic(n) to Ic(n+1). (2) An (n+1)th charge comprises charging the secondary battery at the current Ic(n+1) to a voltage Ec(n+1), and subsequently charging the secondary battery at the voltage Ec(n+1) until the current decreases from Ic(n+1) to Ic(n+2). Consequently, the charge time of the non-aqueous electrolyte secondary battery can be shortened while deterioration of the battery can be suppressed.
