Battery Forced Internal Short Circuit Tester

1. Equipment Overview

The Battery Forced Internal Short Circuit Tester is a precision test equipment specially designed for evaluating the safety performance and thermal runaway behavior of lithium-ion batteries and other types of batteries in the event of an internal short circuit. Internal short-circuit is a serious failure that may occur during the use of batteries, which may lead to a large amount of heat generated inside the battery, and then lead to thermal runaway, or even fire or explosion. Through the mandatory internal short circuit test, it can simulate the internal short circuit situation in actual use and evaluate the safety and stability of the battery under extreme conditions.

2. Main Functions

Internal short-circuit simulation: Create short-circuits inside the battery by mechanical or electrochemical means to simulate the short-circuit situation in actual use.

Thermal runaway assessment: Monitor the temperature change of the battery during the internal short-circuit process, and assess its thermal runaway risk and thermal runaway behavior.

Safety testing: Evaluate the safety performance of the battery under different temperature and pressure conditions to ensure its reliability in actual use.

Data Acquisition and Analysis: Real-time acquisition of battery temperature, voltage, current and other data, and generation of detailed test reports.

Safety Protection: Equipped with multiple safety protection devices, such as explosion-proof box, fire extinguishing system and emergency stop device, to ensure the safety of the testing process.
