Description
技术领域technical field
本发明涉及电动汽车电池领域，具体涉及一种电池包液体冷却/加热系统试验装置。The invention relates to the field of electric vehicle batteries, in particular to a battery pack liquid cooling/heating system test device.
背景技术Background technique
随着能源危机、全球变暖、环境污染等问题的日趋恶化，新能源汽车为未来汽车的发展方向。目前，新能源汽车的发展方向主要集中在混合动力汽车以及纯电动汽车上。而电池及电池包则是混合动力汽车以及纯电动汽车的关键部件。With the deteriorating energy crisis, global warming, environmental pollution and other issues, new energy vehicles are the development direction of future vehicles. At present, the development direction of new energy vehicles is mainly concentrated on hybrid vehicles and pure electric vehicles. Batteries and battery packs are the key components of hybrid electric vehicles and pure electric vehicles.
目前，电动汽车主要使用的是动力锂电池，影响动力电池寿命的主要因素有电池的充放电倍率、充放电截止电压、搁置条件、使用温度等，这几个因素相互影响，相互制约。但就使用温度而言，目前的动力电池单体在极端低温(小于-30℃)和极端高温(大于50℃)的环境下都无法正常工作。针对动力锂电池散热问题，业界发明了不同的冷却装置，主要有气体冷却、液体冷却和相变材料冷却。目前，市场上普遍采用最为简单的空气冷却，然而，如果电动汽车电池在恶劣的热环境下工作时，仅仅依靠空气冷却很难使电池工作在最佳的温度范围。由于液冷冷却系统传热效率高、占用体积小，但成本较高，所以开发一种高效、紧凑、低成本的动力电池液体冷却系统显得尤为重要。At present, electric vehicles mainly use power lithium batteries. The main factors affecting the life of power batteries are battery charge and discharge rate, charge and discharge cut-off voltage, storage conditions, operating temperature, etc. These factors affect each other and restrict each other. However, in terms of operating temperature, the current power battery cells cannot work normally in extreme low temperature (less than -30°C) and extremely high temperature (greater than 50°C) environments. To solve the heat dissipation problem of power lithium batteries, the industry has invented different cooling devices, mainly including gas cooling, liquid cooling and phase change material cooling. At present, the simplest air cooling is commonly used in the market. However, if the electric vehicle battery is working in a harsh thermal environment, it is difficult to make the battery work in the optimal temperature range only by air cooling. Due to the high heat transfer efficiency and small footprint of the liquid cooling cooling system, but the high cost, it is particularly important to develop an efficient, compact, and low-cost power battery liquid cooling system.
