Lithium Battery Temperature Controlled Short Circuit Test Box

Lithium battery temperature controlled short circuit test box STANDARD FEATURES

1. Core function: simulation of short circuit and temperature control environment

The core function of lithium battery temperature-controlled short-circuit tester is to simulate the short-circuit situation that may be encountered in the actual use of the battery, and combined with the temperature control system, to assess the safety performance of the battery under different temperature conditions. The following are its main functions:

- Short-circuit simulation: Through mechanical or electrochemical means, short-circuits are created inside or outside the battery to simulate short-circuit failures in actual use. This function can reproduce the reaction of the battery under abnormal conditions and help engineers assess the safety performance of the battery.

- Temperature Control System: The equipment is equipped with a high-precision temperature control system that can accurately control the temperature of the test environment from -40°C to 150°C. This feature is useful for evaluating batteries at different temperatures. This feature is critical for evaluating the safety performance of batteries under different temperature conditions. For example, at high temperatures, the chemical reaction rate of the battery is accelerated, which may lead to an increased risk of thermal runaway.

- Real-time monitoring: The device has built-in high-precision temperature sensors, voltage sensors and current sensors, which can monitor the temperature change, voltage fluctuation and current change of the battery in the short-circuit process in real time. These data are crucial for analyzing the thermal runaway behavior and safety of the battery.

2. Safety test: assessing the extreme performance of the battery

Lithium battery temperature-controlled short circuit tester is not only able to simulate the short circuit situation, but also assess the safety performance of the battery under extreme conditions:

- Thermal runaway assessment: By monitoring the temperature change of the battery in real time, the equipment is able to assess the risk of thermal runaway of the battery. For example, under high temperature short circuit conditions, the battery may heat up rapidly, leading to thermal runaway and even fire or explosion. The device can record the rate of temperature rise and the maximum temperature to help engineers determine the safety boundary of the battery.

- Safety Verification: The equipment is equipped with multiple safety protection devices, such as explosion-proof boxes, fire extinguishing systems and emergency shutdown devices, to ensure the safety of the test process. These devices can provide effective protection in the event of abnormal battery conditions, preventing accidents from expanding.

- Data Acquisition and Analysis: The equipment has a built-in data acquisition system, which is capable of real-time acquisition of battery temperature, voltage, current and other data, and generating detailed test reports. These data are essential for analyzing the thermal runaway characteristics and safety performance of the battery. For example, by analyzing the rate of temperature rise and maximum temperature, the safety performance of the battery under different temperature conditions can be evaluated.
