The invention relates to a battery pack power determination method and device, a vehicle and a storage medium, and relates to the technical field of computers. The method comprises the steps that the total heat dissipation amount and the total heat production amount of a battery pack under target power are determined; the target power is greater than the rated power of the battery pack, and the difference between the target power and the rated power is greater than a preset threshold; and determining the peak power of the battery pack based on the total heat dissipation amount and the total heat production amount. Therefore, under the peak power, the capacity of the battery pack can be completely released, and the accuracy of the peak power of the battery pack is improved. Therefore, the dynamic property of the vehicle can be improved on the premise of not influencing the service life of the battery pack based on the capability of releasing the battery pack in short time based on peak power.
本申请涉及一种电池组功率确定方法、装置、车辆及存储介质,涉及计算机技术领域。该方法包括:确定电池组在目标功率下的散热总量和产热总量;目标功率大于电池组的额定功率,且目标功率与额定功率的差值大于预设阈值;基于散热总量和产热总量,确定电池组的峰值功率。由此,在峰值功率下,可以完全释放电池组的能力,提高了电池组峰值功率的准确性。从而可以基于峰值功率短时释放电池组的能力,在不影响电池组寿命的前提下提升车辆的动力性。
