Abstract

The invention discloses a temperature control type power battery pack which is used for solving the problem of heat dissipation. The temperature control type power battery pack comprises battery cores, temperature equilibrium pieces and a shell, the shell comprises a main shell body, an upper top plate and an end cover, the battery cores are mounted among partition plates in the main shell body, the two sides of the battery cores are filled with thermally-conductive silicone rubber and the temperature equilibrium pieces, and the partition plates are provided with a plurality of vertically-through through holes which serve as cooling channels. A photo-thermal collection plate is mounted at a car roof, a medium inlet/outlet of the photo-thermal collection plate is connected to a cooling fluid outlet and cooling fluid inlets through a liquid pump, and a heat sink and the photo-thermal collection plate are arranged in parallel. The ceramic shell is adopted, good heat conduction and explosion resistance are achieved, thermal expansion and cold shrinkage can be avoided, safe operation of power batteries is guaranteed, and it is guaranteed that in the operation process, the temperature control type power battery pack is always in the safe control range.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a power battery pack with a temperature control function. Background technique [0002] With the advancement of science and technology, the research on pure electric vehicles has become more and more mature. Due to the characteristics of high efficiency and environmental protection, pure electric vehicles will gradually replace traditional internal combustion engine vehicles in the next few decades and become the world's The main means of transportation on the traffic lines of major cities. However, the performance of power batteries, the source of power supply for pure electric vehicles, has largely restricted the development of electric vehicles. The service life, environmental protection, safety and reliability of batteries often determine the quality of electric vehicles and new energy vehicles. operating status. [0003] A power battery is a battery that can provid...
