Abstract: According to the present invention, there is provided a secondary battery control circuit which can perform a reliable charge/discharge control without activating Positive Temperature Coefficient element. The secondary battery control circuit includes a temperature detection section for detecting a temperature of the secondary battery and a system logic for controlling charging/discharging of the secondary battery based on the temperature detected by the temperature detection section. The system logic interrupts the charging of the secondary battery in a case where the temperature detected by the temperature detection section is out of a predetermined first temperature range, and interrupts the discharging of the secondary battery in a case where the temperature detected by the temperature detection section is out of a predetermined second temperature range.

Abstract: An intermediate product is formed by combining together plurality of constituent elements. The intermediate product is arranged in a mold an then molten resin is charged in the mold. An opening is formed so as to correspond to a plus terminal, a minus terminal, and a temperature detecting terminal in the intermediate product, and its periphery is covered with the resin. Whereupon, a thin enclosed outer packaging body is realized that is made compact and offers excellent dust-proof, drip-proof structure. Alternatively, the intermediate product is housed in an outer packaging case having an open end that allows insertion of the intermediate product, and resin is charged in the open end, thereby achieving sealing.

Abstract: A protective circuit having an electronic circuit constructed on a circuit board is built into a sealing member that seals the open end of a battery case accommodating electricity generating elements. The circuit board is attached to the outer end of the sealing member. A positive terminal plate that becomes the positive terminal of the secondary battery and an S pole terminal plate that controls the operation of the electronic circuit by an external connection are provided on the outer surface of the circuit board. Thereby, a protective circuit that prevents over-discharging and overcharging is arranged inside the sealing member. A secondary battery is thereby constructed with a protective circuit without resorting to a construction of a battery pack.
