| 中文摘要: |
| 随着国家对环保的越发重视，节能与新能源汽车的车型和产量急剧增加，对动力电池包的防护等级和使用寿命的要求越来越高。而电池的使用寿命与所处的温度有很大关系，温度适中，其寿命越长，温度越高寿命越短。本文主要研究圆柱型镍氢电池的电池包设计方案，新开发一种全新的使用浸液冷却的电池包，通过对浸液电池的性能测试，部件的结构设计，热仿真设计及台架和第三方测试验证，有效控制电池温度和提高电池包的防护等级，方案可行，对镍氢电池包后续使用浸液散热提供依据和指导。 |
| 英文摘要: |
| As the country pays more and more attention to environmental protection, the models and output of energy-saving and new energy vehicles increased sharply, and the requirements for the protection grade and service life of power battery pack were higher and higher. The service life of the battery is closely related to the temperature. The moderate temperature is for the longer service life, the higher temperature for the shorter service life. In this paper, the battery pack design scheme of cylindrical Ni MH battery was studied, and a new battery pack using immersion cooling was newly developed. Through the performance test of immersion battery, component structure design, thermal simulation design and bench and third-party test verification, the battery temperature was effectively controlled and the protection grade of battery pack was improved. The scheme is feasible, which can provide basis and guidance for subsequent use of immersion heat dissipation of Ni MH battery pack. |
