Abstract: The electrical equipment battery includes: a circuit board mounted with a heat generating element; and an outer case having a heat radiation plate made of metal. A heat transfer space is defined between the circuit board and the heat radiation plate, and then an electrical-insulating and heat-conducting gel is filled in the heat transfer space. Heat energy of the heat generating element is radiated to the outside via the heat radiation plate of the outer case. The heat radiation plate is provided with a flow-out block partition on the outer side of the heat transfer space. The flow-out block partition suppresses the electrical-insulating and heat-conducting gel from flowing out from the heat transfer space.

Abstract: A battery module that includes a battery and a bidirectional DC-DC converter including a switching element that is arranged at a position where heat generated by the switching element is transmitted to the battery. The bidirectional DC-DC converter operates in a discharge mode in which DC power supplied from the battery is converted and supplied to an input/output unit, and in a charge mode in which DC power supplied from the input/output unit is converted and supplied to the battery. Moreover, a control unit forces the bidirectional DC-DC converter to operate in the discharge mode and to increase a switching frequency of the switching element in comparison with a switching frequency in normal driving, when a temperature in a periphery of the battery needs to be increased.
