Embodiment Construction

[0041] As an important part of the new energy electric vehicle, the battery pack's performance directly determines whether the new energy electric vehicle can run normally and safely. When the battery pack is working, the battery will heat up. If the temperature is too high, it may affect the normal operation of the battery module or even damage the battery module. Existing techniques for thermally managing batteries are mostly ineffective.

[0042] The inventor found through experiments and analysis that the reason for the poor effect of the existing battery thermal management technology is mainly due to the non-uniformity of battery heating. For example, the temperature rise of some batteries in the battery module is too high. However, most of the existing liquid cooling devices are integrated: it is impossible to achieve partial cooling, so there will be a problem. If the battery at the back end of the liquid cooling device needs to be cooled, the regulating liquid will pas...

Abstract

The embodiment of the invention relates to the technical field of battery heat radiation, in particular to a new energy source commercial vehicle battery pack and an electric vehicle. The new energy source commercial vehicle battery pack comprises a box body, a liquid cooling assembly, a sealing ring, a sealing element, a plurality of conflux elements and a plurality of battery modules, wherein the liquid cooling assembly is provided with a plurality of liquid cooling plates; the box body comprises an accommodating cavity with an opening; the liquid cooling assembly is arranged in the accommodating cavity; each battery module is fixedly attached to each liquid cooling plate; all of the conflux elements are arranged among the plurality of battery modules in a staggered way; each conflux element is electrically connected with every two battery modules so as to form a module structure with two free ends; the sealing ring is arranged at the edge of the opening; the sealing element is buckled in a position, far away from the opening edge, of the sealing ring. The new energy source commercial vehicle battery pack has the advantages that the local targeted heat management can be performedon a battery; the heat management effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of battery heat dissipation, and in particular, relate to a new energy commercial vehicle battery pack and an electric vehicle. Background technique [0002] As an important part of the new energy electric vehicle, the battery pack's performance directly determines whether the new energy electric vehicle can run normally and safely. When the battery pack is working, the battery will heat up. If the temperature is too high, it may affect the normal operation of the battery module or even damage the battery module. Existing techniques for thermally managing batteries are mostly ineffective. Contents of the invention [0003] In view of this, the present invention provides a battery pack for a new energy commercial vehicle and an electric vehicle, which can realize local targeted thermal management of the battery and improve the effect of thermal management. [0004] In order to achiev...
