Description
技术领域technical field
本发明涉及一种动力电池热管理系统，尤其是一种适用于电动汽车的可变接触式电池热管理系统。The invention relates to a power battery thermal management system, in particular to a variable contact battery thermal management system suitable for electric vehicles.
背景技术Background technique
随着经济和社会的发展，能源危机和环境污染的日益严重，节能减排越来越重要。汽车尾气占据了碳排放的很大一部分比重，为了减少汽车尾气排放，必须用其他的交通工具代替传统的汽车。电动汽车是替代传统汽车的新型交通工具，电动汽车以电池为动力，由电机驱动。电动汽车具有成本低、清洁无污染、噪音小以及能量转换效率高等优点。With the development of economy and society, energy crisis and environmental pollution are becoming more and more serious, energy saving and emission reduction are becoming more and more important. Vehicle exhaust accounts for a large proportion of carbon emissions. In order to reduce vehicle exhaust emissions, traditional vehicles must be replaced by other means of transportation. Electric vehicles are new vehicles that replace traditional vehicles. Electric vehicles are powered by batteries and driven by motors. Electric vehicles have the advantages of low cost, clean and pollution-free, low noise and high energy conversion efficiency.
动力电池是电动汽车的关键组成部分，其性能决定了电动汽车的续航、动力等整车特性。目前，电动汽车主要使用锂离子电池。锂离子电池具有能量密度大、自放电率小、无记忆效应、循环寿命长、可快充快放等优点。但是，锂离子电池在充放电过程中会产生热量导致自身温度升高，而温度直接影响着电池的循环寿命、效率、可靠性和安全性。过高的温度则会使电池发生热失控，最终导致电池爆炸。因此，必须对动力电池组进行热管理。The power battery is a key component of an electric vehicle, and its performance determines the battery life, power and other vehicle characteristics of the electric vehicle. Currently, electric vehicles mainly use lithium-ion batteries. Lithium-ion batteries have the advantages of high energy density, low self-discharge rate, no memory effect, long cycle life, and fast charging and fast discharging. However, lithium-ion batteries will generate heat during charging and discharging, causing their own temperature to rise, and the temperature directly affects the cycle life, efficiency, reliability and safety of the battery. Excessive temperature will cause thermal runaway of the battery, which will eventually cause the battery to explode. Therefore, thermal management of the power battery pack is necessary.
设计合理的电池热管理系统，不仅能够有效控制电池温度，而且具有良好的均温性能。现有热管理系统主要可以分为三类：空气冷却系统、液体冷却系统和相变材料冷却系统。空气冷却系统对电池的散热效果一般，均温性能很差，不能满足电池的散热要求。相变材料冷却系统虽然能够有效降低电池的温度，均温性能也非常好，但是相变材料的封装问题以及相变过程中的体积变化问题限制了其应用。而液体冷却系统对电池的散热效果很好，因此设计一个具有良好均温性能的液体冷却系统非常有必要。A well-designed battery thermal management system can not only effectively control the battery temperature, but also have good temperature uniformity performance. Existing thermal management systems can be mainly divided into three categories: air cooling systems, liquid cooling systems, and phase change material cooling systems. The heat dissipation effect of the air cooling system on the battery is average, and the temperature uniformity performance is very poor, which cannot meet the heat dissipation requirements of the battery. Although the phase change material cooling system can effectively reduce the temperature of the battery, and the temperature uniformity performance is also very good, but the packaging problem of the phase change material and the volume change problem during the phase change process limit its application. The liquid cooling system has a good heat dissipation effect on the battery, so it is necessary to design a liquid cooling system with good temperature uniformity performance.
