Lithium battery fires: New early warning system under development
Fokus GEFAHR/GUT provides information:
The Bundesanstalt for Materials Research and Testing (BAM) and Vitesco Technologies are jointly planning to develop an early warning system for lithium ion batteries in electric vehicles. Current warning systems only react a few minutes before the electrolyte in the lithium ion battery catches fire. According to EU regulations, an electric vehicle must emit a warning signal at least five minutes before this event. The existing systems only detect defective changes when the lithium ion battery is already severely damaged.
In collaboration with Vitesco Technologies, BAM is working on an early warning system that detects critical changes in individual lithium ion cell at an early stage. The system continuously measures and analyzes the electrical alternating current resistance (impedance) in each lithium ion cell. In an emergency, the early warning system should initiate a vehicle service or trigger protective measures such as switching off individual lithium ion cells. This could not only prevent considerable damage and costs, but also improve the safety of the vehicle occupants from the dangers of battery fires.
