The invention discloses a battery system control method, device and equipment and a storage medium, which are used for adjusting the discharge power of a battery system and ensuring the driving safety. The method comprises the following steps: obtaining the direct-current internal resistance of each single cell based on the average current of the battery system and the voltage drop value of each single cell in the battery system; determining the maximum discharge current of the battery system based on the DC internal resistance of each single cell; obtaining the maximum discharge power of the battery system based on the maximum discharge current; and adjusting the discharge power of the battery system based on the maximum discharge power. In the application, the maximum discharge power of the battery system is determined according to the maximum discharge current, and the discharge power of the battery system is adjusted according to the determined power, so that the problem that a vehicle cannot run to a safe area due to the fact that a power supply is directly cut off due to overhigh discharge power of the battery system is avoided.

    本申请公开了一种电池系统控制方法、装置、设备和存储介质,用于调整电池系统的放电功率,保证行车安全。本申请中基于电池系统的平均电流以及电池系统中每个单体电芯的压降值,得到每个单体电芯的直流内阻;基于每个单体电芯的直流内阻确定电池系统的最大放电电流;基于最大放电电流得到电池系统的最大放电功率;基于最大放电功率对电池系统的放电功率进行调整。在本申请中,通过根据最大放电电流来确定电池系统的最大放电功率,并根据确定出的功率来对电池系统的放电功率进行调整,避免了电池系统因放电功率过大而直接切断电源导致车辆无法行驶至安全区域的问题。
