The present invention relates to a battery protection module, connected to a battery module assembly including at least two sub modules electrically connected with at least two module units. The battery protection module electrically connects the sub modules through a protection circuit part and connection terminals. The battery protection module includes: a power output terminal connected to an external output device; the connection terminals connected to the power output terminal or the sub modules; and the protection circuit part connecting the connection terminals, and set to operate a circuit breaker when a short-circuit current flows. The protection circuit part includes: a circuit breaker (CB) including multiple poles; a safety switch connecting or disconnecting the sub modules mutually; and circuits connecting the connection terminals with the CB and the safety switch. A circuit is formed to make the connection terminals connected via at least one pole of the CB in the protection circuit part. |
