PROTECTION ELEMENT, PROTECTION CIRCUIT AND BATTERY CIRCUIT

WIPO Patent Application WO/2015/156019

A1

According to the present invention, the residual power of a battery stack is safely consumed after interruption of a charge/discharge path. This protection element is provided with: an insulating substrate (21); a heat-generating body (15); first and second electrodes (11, 12) that are laminated on the insulating substrate (21) and are connected to an external circuit; and a fusible conductor (22) that is laminated on the first and second electrodes (11, 12) and a heat-generating body lead-out electrode (18), which is provided between the first and second electrodes (11, 12) and is connected to the heat-generating body (15), and that interrupts a current path between the first electrode (11) and the second electrode (12) by heating. A load resistor (16) is connected in parallel to the fusible conductor (22) between the first electrode (11) and the heat-generating body lead-out electrode (18), and the load resistor (16) is connected in series to the external circuit and the heat-generating body (15).
