Problems solved by technology

As the temperature rises, the discharge capacity of the hydrogen-powered battery decreases, the charging efficiency decreases, the self-discharge increases, and the battery decay speed accelerates sharply
At high temperatures, the temperature inhomogeneity of the hydrogen power battery increases, and the unreasonable design of the heat dissipation structure outside the battery will have a great impact on the heat dissipation of the battery, and even bring some safety hazards
[0003] In the prior art, for the design of the heat dissipation system of the hydrogen-powered battery, most of them adopt the design of the cooling water circulation system (such as the patent document of CN209766553U), through which the water flows in the water pipe, thereby taking away the heat of the hydrogen-powered battery, so that the The cooling effect of the hydrogen-powered battery, but after the cooling water circulation system is used for a long time, the cooling water will absorb more heat than the heat dissipation, which will cause the water temperature to rise and reduce the cooling effect on the hydrogen-powered battery

Description

technical field [0001] The invention relates to the field of intelligent interaction technology, in particular to a heat dissipation integrated system of a hydrogen power battery system. Background technique [0002] The hydrogen battery is the core component of the hybrid electric vehicle system, and its performance will directly affect the performance of the vehicle. Hydrogen-powered batteries have become the preferred power source for hybrid vehicles due to their advantages of no pollution to the environment and high safety performance. However, the heat dissipation of hydrogen-powered batteries during charging and use is one of the main factors affecting their normal application. As the temperature rises, the discharge capacity of the hydrogen-powered battery decreases, the charging efficiency decreases, the self-discharge increases, and the battery decay rate accelerates sharply. At high temperatures, the temperature non-uniformity of the hydrogen-powered battery incre...
