Based on a pure electric prototype vehicle equipped with a PTC water heating system,a low-temperature driving range test was conducted to quantitatively analyze the impact of different battery heating strategies on the low-temperature driving range.The test results show that the battery discharge is related to the end of the test battery temperature and the average temperature of the entire test battery,with the end of the test battery temperature being the main influencing factor;The low battery single battery heating strategy is superior to the full range heating strategy,and the lower the SOC when starting the heating,the better the improvement effect on low-temperature driving range;In a low battery single heating strategy,different heating target temperatures will affect the low-temperature range,and it is necessary to choose an appropriate heating target temperature to achieve the optimal low-temperature range.The experi-mental research results can provide reference for the formulation and optimization of battery thermal management control strategies for pure electric vehicles.
