Abstract:
This battery device (10) is provided with: a battery pack (13); a circuit board (2) for acquiring battery information pertaining to the battery pack, or for controlling charging and discharging of the battery pack; a switch device that includes a first power element (3), a second power element (4), or the like; and a heat dissipation member (6). The switch device controls the input and output of power to and from the battery pack and is installed such that an exterior part (30) thereof is spaced away from the circuit substrate. The heat dissipation member is made of a thermally conductive material, and directly contacts, or indirectly contacts via a thermally conductive member (5), the exterior part of the switch device so that heat of the switch device is able to move. Thus, the performance of this switch device for controlling the input and output of power to and from the battery can be exhibited.
