In a solenoid valve device in which connection terminals, each of which is connected to one of a plurality of solenoid valves fixed in a mounting block, are placed inside a common coupler, a coupler assembly integrally comprising the coupler is detachably mounted on the mounting block at a position which is spaced back from each of the solenoid parts, and elastic connecting members made from an electrically conductive metal are provided between each of a plurality of first flat terminals which are fixedly positioned on the side of the coupler assembly facing the mounting block so as to connect to the corresponding electrically conductive lead members arranged in the coupler assembly and second flat terminals, each of which is arranged at the rear end of each of the solenoid parts so as to be individually opposite the first flat terminals. The solenoid part of each of the solenoid valves and the respective connection terminals inside the coupler can thus be connected and disconnected extremely easily and, moreover, any erroneous connection can be avoided.

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.

A lithium ion secondary battery which includes: a power generation element including a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and a non-aqueous electrolyte; a case accommodating the power generation element and having an opening; and a sealing plate sealing the opening of the case is charged. The sealing plate has an external terminal of the positive or negative electrode, and an internal terminal electrically connected to the positive or negative electrode. The external and internal terminals are connected to each other and have an electrical resistance therebetween of 0.1 to 2 mΩ. Two or more constant-current charging steps in each of which the secondary battery is charged at a constant charge current until a charge voltage reaches an end-of-charge voltage are performed. In the two or more constant-current charging steps, the secondary battery is subjected to constant-current charging at a current Ic(1) of 1 to 5 C until the charge voltage reaches a target voltage Ecs(1). After the charge voltage reached the target voltage Ecs(1), the secondary battery is subjected to constant-current charging at a current Ic(k) satisfying Ic(k)
