According to the vehicle power battery direct cooling system control method, multi-dimensional protection is carried out on the compressor, key functions such as exhaust temperature protection, low-pressure protection and pressure ratio protection are covered, multi-interval design is carried out on each protection function, shutdown protection is achieved when the compressor is abnormal, and the service life of the compressor is prolonged. And three different protection stages of a maintenance interval, a speed reduction interval and a shutdown protection interval are introduced, so that the compressor can be effectively prevented from running under the limiting working condition, the running state of the system can be effectively adjusted on the premise of ensuring the safety of the compressor, the thermal comfort of a passenger compartment is ensured to the greatest extent, and the service life of the passenger compartment is prolonged. And uncomfortable environment in the vehicle caused by shutdown of the compressor is avoided.
本发明提供了一种车辆动力电池直冷系统控制方法,对压缩机进行了多维度保护,涵盖了排温保护、低压保护和压比保护等关键功能,且每个保护功能均进行了多区间设计,不仅在压缩机出现异常时实现停机保护,还引入了“维持区间”、“降速区间”和“停机保护区间”三个不同的保护阶段,由此能够有效防止压缩机在极限工况下运行,确保压缩机安全的前提下,能够有效调节系统运行状态,最大程度地保障乘员舱的热舒适性,避免因压缩机停机导致的车内环境不适。
