An energy storage assembly includes a vertical stack of substantially planar modules. Each module comprises a plurality of energy storage components and a thermally conductive shell comprising a shell top, a shell bottom, shell sides, a shell front, and a shell rear.

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.
