The invention relates to a safety assessment method and device of a battery pack, computer equipment and a storage medium. Dividing the battery pack of the electric vehicle into a plurality of block areas, determining the deformation quantity corresponding to each block area corresponding to the collision type, and determining the danger degree quantized value of each block area according to the deformation quantity corresponding to each block area corresponding to the collision type. According to the method, safety evaluation can be performed on the battery pack of the electric vehicle, and the risk of thermal runaway of the battery when the collision accident of the electric vehicle occurs is reduced.
本申请涉及一种电池包的安全评估方法、装置、计算机设备和存储介质。将电动交通工具的电池包划分为多个分块区域,确定碰撞类型对应的各分块区域对应的形变量,并根据碰撞类型对应的各分块区域对应的形变量,确定各分块区域的危险程度量化值。该方法中能够对电动交通工具的电池包进行安全评价,降低了电动交通工具碰撞事故发生时电池热失控的风险。
