The battery external short circuit test, which evaluates the electrical performance and safety of batteries by short circuiting them from outside to simulate use that may cause fire or rupture. ESPEC can carry out external short circuit tests with high currents of up to 24 kA (a world-first).
Sensors record the cell's reactions. Testing the battery response to the induced internal short provides a 100% reliable testing method to safely test battery containment designs for thermal runaway. This jointly developed and patented technology is available for your company to license and develop into a commercial product.

After implantation of the device in a cell, an internal short circuit is induced by exposing the cell to higher temperatures and melting the wax, which is then wicked away by the separator, cathode, and anode, leaving the remaining metal components to come into contact and induce an internal short. Sensors record the cell's reactions.
The diagnosis of an internal short circuit (ISC) fault is an integral part of thermal runaway warning for lithium-ion batteries. A higher level of accuracy in ISC fault diagnosis needs an artificial intelligence model, but lack of fault data and label …
