The invention provides a power
lithium battery protective housing, and relates to the technical field of power
lithium battery equipment. The protective housing comprises an aluminum box and a cover,a main
electrode male plug and a main
electrode female plug are arranged equally in the middle position of the cover, an
auxiliary electrode male plug and an
auxiliary electrode female plug are arranged equally in the middle position of the aluminum box, a space between the internal and external surfaces of the aluminum box serves as a plastic-aluminum film cavity, the aluminum box is uniformly provided with multiple radiating holes, and position where the plastic-aluminum film cavity makes contact with the back side of the aluminum box is provided with an inflation port, and the inflation port extends to the outer side of the aluminum box and fixed by a press ring. The main
electrode male plug, main electrode female plug,
auxiliary electrode male plug and auxiliary electrode female plug are arranged to meet requirements for different installation positions when
lithium batteries are connected in series and expanded to form a
lithium battery group, a plastic-aluminum housing is selected, the radiating holes are increased, the heat
radiation capability of the lithium batteries can be improved, the plastic-aluminum material is low in weight and high in intensity and
plasticity, and the protective housing of the plastic-aluminum material can improve the
energy density of the power
lithium battery.
