Preceding and subsequent areas of usage

The signs of climate change, scarcity of resources and high fuel prices are driving the development of electric cars. Almost all car companies are working on electric prototypes and bringing series production vehicles to market in the coming years. Various institutes have therefore been studying the safety of electric vehicles for quite some time. The german institute DEKRA Automobil GmbH has also conducted a series of fire protection tests in this field, determining that cars with lithium drive system batteries are at least as safe as conventional vehicles in case of a fire.

Transfered hazards

Lithium batteries are generally considered safe when they are installed in vehicles and connected to the vehicle infrastructure and controllers. As soon as they are removed from this safe, controlled environment, they have to be viewed as dangerous goods and handled accordingly. Therefore the hazards are transferred to upstream and downstream areas such as test stands and charging stations. New fire protection concepts and agents counteract these transferred hazards and help control fire situations.

Fire protection for test stands

The demand for test stand time is increasing sharply right now for the purpose of testing new starter batteries and the batteries for hybrid and plug-in vehicles. Here the use of lithium batteries imposes new requirements in terms of safety and, in particular, fire protection. Overload tests on the test stand or continuous operation tests in the vehicle can lead to a lithium-ion battery fire, which cannot be fought safely using conventional extinguishing agents.
