Abstract:
PROBLEM TO BE SOLVED: To reduce influence of heat evolution of a power reception coil while downsizing a battery pack.SOLUTION: A battery pack is connected to an electric apparatus 80 to supply power for driving the electric apparatus 80 and is mounted on a charge stand 90 to be charged in a non-contact manner by means of receiving power from a power transmission coil 93 included in the charge stand 90. The battery pack comprises: a battery stack 2 composed by stacking a plurality of square battery cells 1 having thickness (t) smaller than width (d) in the thickness direction; a power reception coil 3 capable of being electromagnetically coupled with the power transmission coil 93 included in the charge stand 90; and a circuit board 4 mounting a charge circuit 40 for charging the battery cells 1 with power induced in the power reception coil 3. The power reception coil 3 is disposed on a first surface 2A of the battery stack 2 and the circuit board 4 is disposed on a second surface 2B of the battery stack 2 which intersects with the first surface 2A.
