The invention relates to an automobile battery heating and heat preservation control method based on negative feedback regulation. The method comprises the steps that the environment temperature, the storage battery temperature, the power battery temperature, the liquid domain temperature and the automobile control state are obtained; step 2, judging whether the storage battery temperature, the power battery temperature and the liquid domain temperature are lower than a preset limit temperature, if so, executing step 3, and otherwise, executing step 6; 3, the liquid domain is heated, the current temperature is fed back, whether the current temperature reaches the preset temperature or not is judged, if yes, the step 2 is executed, and if not, the step 4 is executed; 4, feeding back the required heating power by combining the current temperature with the heating transfer function; 5, the heating power is adjusted according to the needed heating power and the power transfer function, and the step 3 is executed; and 6, stopping heating the liquid region to enable the automobile to normally run, and executing the step 1. Liquid domain heating is controlled based on a negative feedback regulation principle, so that the battery can be effectively ensured to be at a proper working temperature in time, and the energy consumption is low.

    本发明涉及一种基于负反馈调节的汽车电池加热保温的控制方法,包括获取环境温度、蓄电池温度、动力电池温度、液域温度以及汽车控制状态;步骤二、判断蓄电池温度、动力电池温度以及液域温度是否低于预设极限温度,若是,则执行步骤三,否则执行步骤六;步骤三、对液域进行加热并反馈当前温度,判断当前温度是否达到预设温度,若是,则执行步骤二,否则执行步骤四;步骤四、以当前温度结合加热传递函数反馈所需加热功率;步骤五、所需加热功率结合功率传递函数调节加热功率,执行步骤三;步骤六、停止对液域加热,使得汽车正常运行,执行步骤一。本发明基于负反馈调节原理控制液域加热可及时有效的保证电池处于合适的工作温度,且能耗低。
