Abstract
An electrical storage apparatus 1 includes a plurality of battery modules 10 and cooling passages A, B for cooling each of the battery modules 10. The cooling passage A is configured so as to cool all battery modules 10 mounted in the electrical storage apparatus 1 at all times during charging. The cooling passage B is configured so as to cool only a new battery module 10a as a replacement during charging. This enables the battery module 10a having a temperature during charging higher than that of a battery module 10 yet to be replaced to be subject to forced cooling, thereby preventing performance of the battery module 10a from being degraded.
