Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a heat management system and a management method for a hybrid electric vehicle. Background technique [0002] Compared with traditional fuel vehicles, hybrid electric vehicles (HEVs) have more heat sources and larger temperature spans. With the deepening of hybrid power, the heat management requirements of power batteries cannot be ignored. In order to better To coordinate the heat in the HEV and improve the energy efficiency of the whole vehicle, further optimization of the thermal management system is required. A complete thermal management solution needs to involve engine controller (EMS), vehicle controller (VCU), battery management system (BMS), and the system is complex. Therefore, OEMs are now choosing more independent cooling systems. In order to utilize the limited energy of vehicles more efficiently, it is necessary to reasonably couple and utilize the ther...
