A TESTING TOOL FOR BATTERY PACKS TO IDENTIFY AND STUDY FAILURE MODES AND SAFETY ISSUES

A TESTING TOOL FOR BATTERY PACKS TO IDENTIFY AND STUDY FAILURE MODES AND SAFETY ISSUES

The LYRA internal short circuit (ISC) trigger cell, utilizing proprietary technology exclusively licensed to KULR by the National Renewable Energy Laboratory (NREL) and NASA, is the ideal testing tool for your batteries and battery packs. Through its use, failure conditions of a cell are mimicked in order to identify and study the failure modes and safety issues that could arise within Li-ion batteries and battery packs.

Historically, nail penetration tests have been used to short circuit Li-ion cells. This is widely considered an archaic testing method that has a number of drawbacks. NREL and NASA noted a need for change in these testing methods and subsequently developed a new, more controlled and reliable testing method for lithium-ion batteries. The LYRA is a battery cell that comes in 18650, 21700, and pouch versions and includes the VEGA ISC trigger device securely placed inside. The VEGA is intentionally triggered on demand causing the LYRA to short circuit. Failure modes and safety issues can be identified and studied with the aid of the LYRA. This is a valuable engineering tool for research institutes, battery manufacturers, and OEMs looking to improve the performance and safety of Li-ion batteries and battery packs.
