Embodiment Construction

[0013] The electric vehicle battery of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the electric vehicle battery of the present invention includes an aluminum case 1, an upper cover 2 and a lower cover 3, the aluminum case is a square body, the upper cover and the lower cover are respectively installed at two ends of the aluminum case, and the aluminum case is a cavity Body, the outer circumference of the aluminum shell is strip-shaped, which plays the role of structural stability and heat dissipation. There is an aluminum support structure 4 inside the aluminum shell. The aluminum support structure plays a role of structural stability and heat conduction. The cavity in the aluminum shell is divided into ten sub-districts, and ten sheet-shaped soft-packed lithium iron phosphate batteries are placed in each sub-district. 7. The lithium iron phosphate battery is outsourced with...

Abstract

The invention discloses an electric vehicle battery which is characterized by comprising an aluminum shell internally provided with soft bag lithium iron phosphate batteries. The interior of the aluminum shell has an aluminum bracket structure and is divided into ten cells, and each cell is internally provided with ten flaky soft bag lithium iron phosphate batteries. Insulating reinforced paper is wrapped outside each lithium iron phosphate battery, and the upper ends and the lower ends of the lithium iron phosphate batteries are fixed in each cell in the aluminum shell. The positive pole and the negative pole of each lithium iron phosphate battery collect current by a copper billet and output the current through a connection column, wherein an insulator on the periphery of the connection column is fixed on an upper cover of the aluminum shell, and the periphery of the connection column is provided with an inner nut convenient for the parallel connection and the series connection of battery units. The soft bag lithium iron phosphate battery is a battery unit of 3.2V and 200AH, which is assembled by parallel connection of ten single lithium iron phosphate batteries of 3.2V and 200AH. The invention has the advantages of high efficiency, good performance, long service life, low cost and no environmental pollution.

Description

technical field [0001] The invention relates to an electric vehicle battery, in particular to an electric vehicle battery with high efficiency, good performance, long service life, low cost and no pollution to the environment. Background technique [0002] At present, the batteries commonly used in electric vehicles include lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries. Lead-acid batteries are cheap, but the weight and volume are too large, the energy density and power density are low, and they pollute the environment. This kind of battery is basically not used in electric vehicles. The energy density and power density of Ni-MH batteries are superior to lead-acid batteries, and are widely used in electric vehicles. The performance of lithium-ion batteries is better than that of nickel-metal hydride batteries. At present, it has attracted more and more attention, and it has been used more and more in electric vehicles. At present, lithium-ion...
