BAC-1000AE

The BAC-420BE is an adiabatic calorimeter for large battery cells and small modules measuring 100mm to 600mm in length. It conducts tests including battery thermal runaway, gas generation, heat generation during charge/discharge cycles, and specific heat capacity measurement. It precisely quantifies parameters such as heat generation during lithium battery charging and discharging, specific heat capacity, thermal runaway onset temperature, maximum thermal runaway rate, adiabatic temperature rise characteristics, gas generation volume, and gas generation rate, especially under low-temperature conditions.

Features

Features adiabatic thermal runaway, auxiliary heating with heating wires, gas collection and pressure testing, thermal/electrical/mechanical abuse, specific heat capacity testing, charge/discharge heat generation testing, multi-point temperature measurement, and video surveillance.

The standard low-temperature cooling module can reduce the initial experimental temperature to -25℃.

Self-exothermic detection sensitivity is significantly better than the standard threshold of 0.02℃/min, with high adiabatic performance and minimal wall-sample temperature difference.

An innovative auxiliary heating wire solution can increase experimental efficiency by up to 5 times.

The furnace features a bursting disc and spring lock design, and includes a standard explosion-resistant box. This dual protection ensures the safety of both experimental personnel and equipment.
