Button battery short circuit testing equipment

Coin cell short circuit test equipment is a precision test equipment specially designed to evaluate the safety performance, thermal runaway behavior and potential hazards of coin cell batteries (such as lithium manganese batteries, silver oxide batteries, zinc air batteries, etc.) under short circuit conditions. Since button batteries are usually used in small electronic devices, such as watches, hearing aids, calculators, etc., they may rapidly heat up under short-circuit conditions, leading to thermal runaway, fire or explosion. Therefore, this equipment evaluates the safety and stability of batteries under extreme conditions by simulating short-circuit failures that may occur in actual use to ensure their reliable application in small electronic devices.

2. Main Functions

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

- Thermal runaway assessment: real-time monitoring of the temperature change of the battery during the short-circuit process, assessing its thermal runaway risk and thermal runaway behavior.

- Safety testing: Evaluate the safety performance of the battery under short-circuit conditions, including whether smoke, fire, explosion and other dangerous situations will occur.

- Data Acquisition and Analysis: Real-time acquisition of battery temperature, voltage, current and other data, and generation of detailed test reports to help analyze the thermal runaway characteristics and safety performance of the battery.

- 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.

- Miniature fixture design: Aiming at the small size of button batteries, special miniature fixtures are designed to ensure the accuracy and reliability of short-circuit testing.
