Distributed acquisition module for power battery pack

Abstract

The invention discloses a distributed acquisition module for a power battery pack. The distributed acquisition module comprises a module main body, according to the distributed acquisition module for the power battery pack, through the arrangement of the acquisition module, the acquisition module adopts a standardized unit, the universality is high, and the standard size can be applied to large modules of different specifications and types; the acquisition module is connected with the FPC in a HotBar welding manner, so that safety and reliability are realized; the acquisition module takes electricity, no external power supply is connected, only the daisy chain communicates with the outside, and the external wiring is extremely simple; the acquisition module adopts a bottom thermal protection insulation sheet scheme and is isolated from a battery cell thermal runaway exhaust channel; the top of the acquisition module and the top of the module form a heat exchange path through a heat-conducting insulating sheet, so that the heat dissipation requirements of work such as equalization are met, and the large-module integrated CCS acquisition technology shows remarkable advantages in the aspects of improving the energy density of the power battery, reducing the cost and enhancing the safety and reliability; and the method has important significance on improving the market competitiveness of the new energy automobile.
