An onboard battery for a vehicle includes battery modules including battery cells disposed in a predetermined state, and a cell cover in which the battery cells are disposed. A part of an internal space of the cell cover is formed as chambers into which cooling air is sent. The onboard battery also includes a housing case that houses the battery modules, an intake duct that sends the cooling air into the battery modules, and an exhaust duct that discharges the cooling air sent into the battery modules. A heater that heats the battery cells is disposed in one of the chambers. A heat sink located opposite to the battery cells and attached to the heater is disposed in the one of the chambers. |
