Battery system thermal runaway simulation device and simulation method

Abstract

The invention relates to a battery system thermal runaway simulation device. The battery system thermal runaway simulation device comprises a module cell, a heating triggering device, a module outer frame, a heating control device and a signal acquisition device, wherein the module cell is used for simulating a battery to be tested; the heating triggering device is in close contact with the modulecell and is used for heating the module cell; the heating triggering device and the module cell are placed in the module outer frame; the heating control device is electrically connected with the heating triggering device; and the signal acquisition device is electrically connected with the module cell and acquires signals on the module cell. According to the device, the problem that the escape time of passengers cannot be known after the existing battery pack is out of control is solved, and the battery system thermal runaway simulation device is provided, which aims to solve the technical problem that the time of transferring to a passenger compartment after thermal runaway of the battery pack is accurately obtained through simulation so as to reduce casualties caused by thermal runawayof the battery.

Description

technical field [0001] The invention relates to a thermal runaway simulation device and a simulation method, in particular to a thermal runaway simulation device for a battery system. Background technique [0002] The problem of casualties and property losses caused by spontaneous combustion after a car collision has always touched the nerves of the public. It is imminent to evaluate the time it takes for the battery pack to be delivered to the passenger compartment after the thermal runaway to allow passengers enough escape time. The corresponding test standards are also in place. under development. Therefore, it is particularly important to design a simple and effective device for simulating the actual thermal runaway of the battery. Contents of the invention [0003] The purpose of the present invention is to overcome the existing problem that the escape time of passengers cannot be known after the thermal runaway of the battery pack, and provide a battery system therm...
