Abstract

A herein disclosed battery system 1 includes two kinds of contactors, i.e., a first contactor 40 and a second contactor 50. The first contactor 40 includes a first positive electrode terminal 42 connected to a positive electrode 11Ap of a battery unit 10, and includes a first negative electrode terminal 44 connected via a positive electrode output terminal 20 to an external load 100. In addition, the second contactor 50 includes a second positive electrode terminal 52 connected to a negative electrode 11Nn of the battery unit 10, and includes a second negative electrode terminal 54 connected via a negative electrode output terminal 30 to the external load 100. Then, the herein disclosed battery system 1 is configured to preferentially turn OFF the contactor, in which a forward electric current flows,during both of an electrical charge and an electrical discharge. Accordingly, the electric current can be safely and promptly interrupted, and thus it is possible to inhibit an malfunction due to welding of the contactor.
