Embodiment Construction
[0044] Such as Figure 1 to Figure 14 As shown, for existing defects, the subject of protection of the present invention is as follows:
[0045] The development is a power battery pack. There are two situations in the installation process of the existing cylindrical lithium battery. One is to directly bundle it to form a power battery pack. The problem with this power battery pack is that it is easy to accumulate heat , resulting in temperature rise, self-expansion, and liquid leakage. For this problem, the existing solution is to add a frame. The existing frame has heat proof and cold contraction phenomenon is still obvious, such as the scheme announced in Chinese patent CN204927374U. The bracket is made of injection molding, which has the functions of insulation and positioning, and can facilitate the assembly of the cylindrical lithium battery. However, the above-mentioned structure does not form an air duct, which does not fundamentally solve the heat dissipation of the ba...

Abstract
The invention discloses a compact power battery pack which comprises a shell, ceramic shells, a metal arc-shaped plate, a left shell body, a right shell body and a bottom plate. The shell is a noncombustible engineering plastic injection molding part and is shaped like an n composed of a top plate, a left plate and a right plate, the ceramic shells are vertically-through ceramic sintering parts, the four corners of each ceramic shell are provided with the metal arc-shaped bodies respectively, the two edges of each metal arc-shaped body are arranged on positioning convex clamps, and a battery cell is clamped into the center of every four metal arc-shaped bodies and makes linear contact with the metal arc-shaped bodies. According to the compact power battery pack, cold air passes around all battery cell monomers according to designed lines; in addition, a space in an inner cavity is large, therefore, the air speed can be decreased, and the cold air and the battery cells generate heat to the maximum extent to achieve heat exchange to generate a good heat exchange effect.
Description
technical field [0001] The invention relates to the technical field of power batteries, specifically power battery packs for new energy vehicles. Background technique [0002] At present, lithium-ion power batteries are popular in my country. Lithium iron phosphate batteries refer to lithium-ion batteries that use lithium iron phosphate as the positive electrode material. [0003] There are many kinds of positive electrode materials for lithium-ion batteries, mainly including lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobaltate is currently the positive electrode material used in most lithium-ion batteries, while other positive electrode materials have not been mass-produced in the market due to various reasons. Lithium iron phosphate is also one of the lithium-ion batteries. In terms of the principle of materials, lithium iron phosphate is also an intercalation / deintercalation pr...
