Embodiment Construction
[0017] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0018] combine figure 1 , the present invention provides a power battery tab heat dissipation system that can exhaust exhaust gas. On the basis of not changing the original heat management system, it combines the advantages of air cooling and liquid cooling heat management methods, effectively solving the traditional liquid cooling heat management method The disadvantage of being unable to exhaust the exhaust gas generated in the thermal management system; at the same time, using the thermal management method of battery tab heat dissipation can efficiently dissipate heat from the battery module and further improve the temperature uniformity of the system; multi-layer safety protection is set in the system, It can better avoid the current frequent battery thermal runaway problem and promote the development of new energy hybrid and pure electric vehicles.
