The invention discloses a thermal management control system and method for a battery pack of a hybrid electric vehicle. The control system comprises an engine cooling control module, an air conditioner refrigerant control module and a battery pack thermal management control module. The engine cooling control module comprises an engine waterway assembly, an engine water temperature sensor, a one-way valve and a heat exchanger which are sequentially connected in series; the air conditioner refrigerant control module comprises an air conditioner system assembly, an electronic expansion valve and a refrigerant plate heat exchanger which are sequentially connected in series; and the battery pack thermal management control module comprises a battery pack internal waterway assembly, an electronic water pump, a two-position three-way electromagnetic valve, a refrigerant plate heat exchanger and a heat exchanger which are sequentially connected in series. According to the control system, four thermal management control modes of pre-cooling at medium and low temperature, high-efficiency heat exchange cooling at high temperature, heating at extremely low temperature and energy balance of the battery cell are designed, so that the battery pack can be freely switched between an energy-saving mode and a high-efficiency mode along with changes of an external environment, a whole vehicle load and the temperature of the battery cell, and invalid energy consumption of the battery pack is reduced.

    本发明公开了一种混合动力汽车电池包热管理控制系统及控制方法,该控制系统包括发动机冷却、空调冷媒和电池包热管理控制模块,所述发动机冷却控制模块包括依次串联的发动机水路总成、发动机水温传感器、单向阀、和换热器;空调冷媒控制模块包括依次串联的空调系统总成、电子膨胀阀和冷媒板换;电池包热管理控制模块包括依次串联的电池包内部水路总成、电子水泵、两位三通电磁阀、冷媒板换和换热器。本发明控制系统设计了中低温下的预冷却、高温下的高效换热冷却、极低温下的加热、电芯的能量均衡四种热管理控制模式,使电池包可以随着外部环境、整车负荷以及电芯温度的变化,在节能模式和高效模式下自由切换,减少了电池包的无效能耗。
