Abstract

The invention relates to the field of safety testing for power supply devices, in particular to a battery safety experiment tool and system. The battery safety test tool comprises an induction heatingtool including a box body, an induction coil, an induction heating power supply, and a processor. The induction coil is used for heating a battery after being electrified to realize a battery thermalinstability experiment; the induction heating power supply connected with the induction coil is used for providing power for the induction coil; and the processor connected with the heating power supply is used for adjusting the output power of the heating power supply. The induction coil is arranged outside the box body; and the induction heating power supply and the processor are arranged inside the box body. The battery safety experiment system is composed of an electronic terminal and the battery safety experiment tool; and the electronic terminal carries out communication with the battery safety experiment tool. With the battery safety experiment tool and system, when the thermal instability experiment of the battery is carried out, the temperature of the battery rises quickly; moreover, the experiment operation becomes simple and the single thermal out-of-control experiment efficiency of the lithium battery cell is effectively improved.

Description

technical field [0001] The invention relates to the field of safety testing of power supply devices, in particular to a battery safety experiment tool and system. Background technique [0002] Lithium battery modules are the energy core of electric vehicles, providing power for electric vehicles. However, during use, the lithium battery cells in the lithium battery module may have the risk of thermal runaway and puncture, causing the surrounding lithium battery cells to burn. , Explosion spraying, etc., when the situation is serious, it will even cause the safety of the whole vehicle and endanger the life safety of personnel. The inventor found that the traditional lithium battery cell thermal runaway experiment uses heating wire to heat the lithium battery cell, the temperature rise rate is slow (a few degrees Celsius per second), and the experiment operator needs to manually wind, which is time-consuming and causes lithium The efficiency of the thermal runaway test of the...
