Understanding the Functionality of Thermal Propagation Tests

The testing methodology involves deliberately inducing thermal runaway in one cell (the trigger cell) within a battery pack or system, and subsequently evaluating the thermal propagation to adjacent cells and modules. To induce thermal runaway in the trigger cell, various methods tailored to the customer's product specifications can be applied, including:

1. Heater Heating (External Heating)
- External heat is applied to induce thermal runaway.

2. Nail Penetration (Internal Heating)
- Physical internal short circuiting is triggered by inserting a metal nail.

3. Overcharging (Electrical Overload)
- A voltage exceeding the specified limits is applied to chemically induce runaway.
Note: This method is not applicable for cylindrical cells utilizing PTC elements or CID.

This comprehensive approach to testing ensures that the safety measures are thoroughly evaluated under conditions that mimic real-life scenarios, providing the necessary data to mitigate risks effectively.
