The invention relates to the technical field of low-temperature heating of power batteries of new energy automobiles, in particular to a pulse heating parameter determination method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining the current temperature and the actual charge state of a power battery; judging whether the power battery meets a preset pulse heating condition or not according to the current temperature and the actual charge state; if the power battery meets the preset pulse heating condition, the target heating frequency and the target heating amplitude are matched to generate a pulse heating request, and the pulse heating request is sent to a control system of the vehicle, so that the control system conducts pulse heating on the power battery according to the target heating frequency and the target heating amplitude. Therefore, the problem of battery capacity attenuation possibly caused by only pursuing the maximum temperature rise rate and neglecting the optimal temperature rise parameter in the pulse heating process is solved, the preheating duration of the power battery is shortened, the test period is shortened for subsequent industrialization application, and the test cost is saved.
本申请涉及新能源汽车动力电池低温加热技术领域,特别涉及一种脉冲加热参数的确定方法、装置、电子设备及存储介质,其中,方法包括:获取动力电池的当前温度和实际荷电状态;根据当前温度和实际荷电状态判断动力电池是否满足预设脉冲加热条件;若动力电池满足预设脉冲加热条件,则匹配目标加热频率和目标加热幅值,以生成脉冲加热请求,并发送脉冲加热请求至车辆的控制系统,使得控制系统按照目标加热频率和目标加热幅值对动力电池进行脉冲加热。由此,解决了由于在脉冲加热过程中仅追求最大温升速率而忽略温升最优参数下可能导致的电池容量衰减的问题,缩短了动力电池的预加热时长,为后续产业化的应用缩短了测试周期并节省了测试成本。
