The invention discloses a new energy automobile winter battery heat preservation method and a vehicle, and belongs to the technical field of new energy automobiles, and the method comprises the steps that when heat preservation request data is received, temperature data of all battery modules are obtained through a temperature sensing module and sent to a heat preservation temperature duration analysis module; the heat preservation temperature duration analysis module obtains the heat preservation duration and the temperature of each part of the battery module according to the temperature data of each part of the battery module, and sends the heat preservation duration and the temperature of each part of the battery module to a car ACU; and the car ACU is matched with the fitting control curve according to the heat preservation duration and the temperature of each battery module to obtain a heating and heat preservation module control instruction and sends the heating and heat preservation module control instruction to the heating and heat preservation module. According to the invention, the relative temperature of the battery module can be adjusted according to the change of the ambient temperature in winter, so that the charge-discharge performance, the capacity characteristic and the cycle life of the battery in a cold environment are ensured.

    本发明公开了一种新能源汽车冬季电池保温方法及车辆,属于新能源汽车技术领域,包括:当接收到保温请求数据时,通过温度感应模块获取各部分电池模组的温度数据并发送至保温温度时长分析模块;所述保温温度时长分析模块通过所述各部分电池模组的温度数据得到各部分电池模组的保温时长及温度,将所述各部分电池模组的保温时长及温度发送至轿车ACU;所述轿车ACU根据所述各部分电池模组的保温时长及温度与拟合控制曲线匹配得到加热保温模块控制指令并发送至加热保温模块。本发明能够根据冬季环境温度的变化,调节电池模组的相对温度,从而保证电池在寒冷环境下的充放电性能、容量特性以及循环寿命。
