The invention discloses a power variable load limiting method, system and device and a medium. The power variable load limiting method comprises the steps that the current output power of a vehicle electric pile and the target power needed by a vehicle are obtained; determining the variable load speed of the output power of the electric pile according to the current output power and the target power, and limiting the variable load speed when the vehicle meets a preset condition, the preset condition comprises at least one of the following conditions: the time period from the vehicle electric pile to the last starting time exceeds a first time period, the current humidity of the vehicle electric pile meets the preset humidity, the current temperature meets the preset temperature, and the BOP system of the vehicle meets the preset operation condition. By using the method, under the preset condition and when the power of the vehicle needs to be suddenly increased or suddenly decreased, the variable load speed of the battery can be limited, so that the service life of the electric pile is prolonged.

    本发明公开了一种功率变载限制方法、系统、设备及介质,功率变载限制方法包括获取车辆电堆的当前输出功率以及车辆所需要的目标功率;根据当前输出功率以及目标功率确定电堆的输出功率的变载速度,当车辆符合预设条件时,限制变载速度,预设条件包括车辆电堆距离上一次开机超过第一时间段、车辆电堆所处的当前湿度符合预设湿度、当前温度符合预设温度、车辆的BOP系统满足预设运行条件中的至少一种。使用本方法,在预设条件下且车辆的功率需要突然上升或者突然下降,则将可以将电池的变载速度进行限制,使得电堆的使用寿命增加。
