Summary:The invention provides a battery safety assessment method. The method comprises the following steps: constructing a battery pack simulation model; circularly charging and discharging the battery pack simulation model, and dividing the battery simulation module into a first type of battery module and a second type of battery module; circularly charging and discharging the battery pack, and acquiring a first external characteristic parameter of a first type of battery modules and a second external characteristic parameter of a second type of battery modules of the battery pack under different battery cycle lives in real time; when the cycle life of the battery is lower than a preset threshold value, collection is stopped; constructing a first standard model and a second standard model according to the first external characteristic parameter and the second external characteristic parameter; third external characteristic parameters of the tested battery in the working process are collected, and a change curve of
