The invention provides an electric vehicle battery heater control method and device, electronic equipment and a storage medium, and belongs to the technical field of new energy automobile equipment control. By adopting the control method for the battery heater of the electric vehicle, a certain amount of power threshold value is reserved for entering each gear based on the actual power performance of the battery heater under each gear, and the power fluctuation generated by gear switching of the battery heater is absorbed by using the margin range; the adverse effect on the battery and the charger caused by over-limit of the discharging power of the battery and the usable power of the battery heater of the charger is avoided, meanwhile, the actual maximum power of the battery heater is selected by integrating multiple factors, and the optimal heating speed and working stability are guaranteed. The technical problem that in the prior art, the service life of a power battery is affected due to the defects existing in the gear switching process of a power battery heater can be solved.

    本发明提供了一种电动车电池加热器控制方法、装置、电子设备和存储介质,属于新能源汽车设备控制技术领域。采用该电动车电池加热器控制方法,基于电池加热器各档位下的实际功率表现,为进入各档位预留一定量的功率阈值,用这个余量范围吸收电池加热器档位切换产生的功率波动,以避免电池放电功率和充电机电池加热器的可使用功率超限而造成的对电池和充电机的不利影响,同时综合多项因素对电池加热器的实际最大功率进行选择,保证最优加热速度和工作稳定性。能够解决现有技术中因动力电池加热器在进行档位切换过程中存在的缺陷而影响动力电池使用寿命的技术问题。
