RELAY CONNECTOR AND BATTERY PACK

摘要

Sneaking of a charging current to a load is avoided, a voltage of a battery is not output to terminals of a connector, and the number of installed switch elements that make conductive or interrupt a feeding path is minimized. A battery pack 100 including a battery 10 that supplies power to a load 20 and to which power is supplied from a charger 40 includes: a relay connector 36 including first, second, and third terminals; a first feeder 13 that connects the load to the first terminal of the relay connector; a second feeder 11 that connects one electrode terminal of the battery to the second terminal of the relay connector; a third feeder 16 for which one terminal is connected to the third terminal of the relay connector; and a switch element 16a that is connected between the other terminal of the third feeder, and the other electrode terminal of the battery. The first terminal and the second terminal of the relay connector are short-circuited by a jumper wire 37a of a jumper plug 37, and the second terminal and the third terminal of the relay connector are respectively connected to one electrode feeder and the other electrode feeder of the charger by using a charging connector 38.
