According to the low-temperature starting method and device of the fuel cell, the electronic equipment and the vehicle, the net output power of the fuel cell is consumed through the heating assembly, the problem that a power cell is overcharged under the low-temperature condition is avoided, heating of the fuel cell and the power cell is achieved, the charging power of the power cell is improved, and the vehicle safety is improved. When the fuel cell reaches the cold start condition and the charging power of the power cell is smaller than the net output power of the fuel cell, the fuel cell is started smoothly, and it is guaranteed that the vehicle can be powered on smoothly. And when the temperature difference is greater than the preset temperature difference threshold value, the net output power is redistributed, so that the balance of the internal temperature of the power battery is improved, and the influence of the consistency of the single batteries on the service life of the power battery is reduced.
本申请提供一种燃料电池的低温启动方法、装置、电子设备及车辆,通过利用加热组件消耗燃料电池的净输出功率,避免了低温条件下动力电池过度充电的问题,还实现了对燃料电池和动力电池的加热,提升动力电池的充电功率,实现对动力电池的充电,在燃料电池达到冷启动条件,且动力电池充电功率小于燃料电池净输出功率时使燃料电池顺利启动,保证车辆可以顺利进行上电。并在温差大于预设的温差阈值时,对净输出功率进行重新分配,以改善动力电池内部温度的均衡性,减少单体电池的一致性对动力电池寿命的影响。
