This study proposes an Auxiliary Power Unit (APU) control strategy C that considers battery SOC, vehicle power, and battery temperature in order to improve the range of REEV at high temperatures while meeting the cooling requirements of the battery and cabin. Experimental results show that strategy C not only reduces fuel consumption, but also increases the cooling rate of the battery and cabin.
To improve the range of REEV (Range Extend Electric Vehicle) at high temperatures while meeting the cooling requirements of the battery and the cabin, this study proposes an APU (Auxiliary Power Unit) control strategy C that considers battery SOC (State of Charge), vehicle power, and battery temperature. Strategy C is also compared with strategy A (only considering battery SOC) and strategy B (considering battery SOC and overall vehicle power). The experimental results show that strategy C not only reduces the fuel consumption of the REEV but also increases the cooling rate of the battery and cabin. The fuel consumption of strategy C is 12.2% and 1.49% lower than that of A and B, respectively. In terms of cooling rate, the battery and cabin cooling rates under strategy C were improved by 0.57% and 2.32% over strategies A and B, respectively, and the fuel consumption of strategy C was 1.49% lower than that of strategy B.
