Problems solved by technology

[0002] The voltage and power of the battery and battery PARK cells are relatively small, which cannot meet the application requirements of energy storage systems and electric vehicles. It is necessary to connect multiple low-voltage batteries and battery PARK cells in series to form a battery string of high and low voltage levels.
[0003] At present, the structure of the PACK box is spliced ​​by multiple cell frames, and there are spacers between the cell frames, and then the assembled frame and spacers are fixed to each other with several long bolts. The structure of this structure The installation of the PACK box is time-consuming and laborious, and each single battery cell must be installed separately, which greatly reduces the assembly efficiency and increases the labor cost; in addition, the heat dissipation performance of the PACK box with this structure is very poor, and once the battery cell In case of liquid leakage, the base of the box is prone to leakage

Abstract

The invention discloses the field of batteries, and particularly relates to a multi-module combined PACK box body. The multi-module combined PACK box body comprises a base, a baffle plate and a partition plate ; and a groove is formed in the base; the baffle plate surrounds the periphery of the base and forms a cavity for containing a battery cell; and the partition plate is used for positioning the battery cells and located between the base and the baffle, a mounting assembly for mounting the partition plate is arranged on the base, a gap is reserved between every two adjacent battery cells, and a soft cushion is arranged on the side, extending into the gap, of the partition plate. The multi-module combined PACK box body is convenient to assemble and excellent in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a multi-module combined PACK box body and a battery pack assembly method. Background technique [0002] The voltage and power of the battery and battery PARK monomers are relatively small, which cannot meet the application requirements of energy storage systems and electric vehicles. It is necessary to connect multiple low-voltage batteries and battery PARK monomers in series to form a battery string of high and low voltage levels. [0003] At present, the structure of the PACK box is spliced ​​by multiple cell frames, and there are spacers between the cell frames, and then the assembled frame and spacers are fixed to each other with several long bolts. The structure of this structure The installation of the PACK box is time-consuming and laborious, and each single battery cell must be installed separately, which greatly reduces the assembly efficiency and increases the labor c...
