Triggering Capabilities
-
Needle Penetration Trigger Equipped with various diameters ranging from 3mm to 8mm steel needles, it supports high-precision displacement control and adjustable puncture speed, precisely simulating the internal short circuit caused by foreign object puncture.
-
High-Temperature Heating Using ceramic heating, flexible heating sheets or induction heating methods, it can rapidly increase the temperature from room temperature to the heat runaway trigger point, with precise and stable temperature control.
-
Overcharge Trigger The built-in high current and high voltage charging and discharging interface enables direct triggering of overcharge and overdischarge and other types of electrical abuse.
-
Laser Triggering By leveraging the high energy density characteristic of lasers, we can achieve localized, non-contact, and precise thermal triggering.

FAQ
-
The equipment is specifically designed for battery destructive testing. The inner liner is made of 304/316 corrosion-resistant stainless steel, which can be directly cleaned with a high-pressure water gun, making maintenance very convenient.
Modular Design for Wearable Parts: The needle assembly and heating plate are both of quick-change structure, making replacement easy.
Just clean up the combustion residue in time and check the sensor lines, and the equipment can undergo multiple repeated thermal runaway tests, eliminating the need for frequent factory repairs. -
The equipment adopts closed-loop control:
1. Displacement control: Servo motor drives the needle, with an accuracy of ±0.1mm
2. Temperature control compensation: PID constant temperature regulation, eliminating environmental errors -
The thermal runaway of the battery will produce toxic and corrosive smoke such as HF, CO, and hydrocarbons.
The equipment is equipped with a dedicated smoke treatment interface, which can be linked to the laboratory scrubber or purification system. After the test, it will automatically expel the air forcefully, and the exhaust gas will be filtered through multiple stages including activated carbon and alkaline washing, achieving compliance with emission standards and protecting the laboratory environment and personnel safety. -
The Thermal Runaway Testing Machine (TA-RSK-PC) is designed to accommodate a wide range of battery types including lithium-ion, lithium polymer, and lithium iron phosphate cells. It supports cylindrical, prismatic, and pouch form factors. The explosion-proof box and heating plate dimensions are fully customizable to suit different battery sizes and module configurations.
-
Yes. The system supports both overcharge and heating trigger modes as standard, and can be configured to execute them in a defined sequence within a single test session. Additional trigger modes such as needle penetration and laser triggering can be integrated as optional add-ons. The computer programming control interface allows users to set up multi-step test protocols for comprehensive battery abuse testing.
