Bosch Devices Prevent Electric Shock in Electric Vehicles Accidents

With more electric cars on the road, many drivers are uncertain what they should do or not do in the event of a collision. Electric motors also present rescue crews with new challenges. In fact, like any other vehicle, electric vehicles are equipped with safety features for such events.

Bosch semiconductors help prevent the risk of electric shock after an accident. Specially designed microchips deactivate the vehicle’s power circuits in a fraction of a second. This enables rescue crews to set to work immediately and ensures that first responders and the vehicle’s occupants remain safe.

“Our semiconductor technology plays a vital role in the safety of hybrid and electric vehicles,” says Jens Fabrowsky, member of the executive management of Bosch’s Automotive Electronics division. Bosch supplies vehicle manufacturers with semiconductor chips for incorporation in special systems that safely disconnect the battery in the event of a collision.

“Faced with the growing number of electric vehicles that could potentially be involved in collisions, such systems are absolutely essential if we are to fulfill our mission of helping and rescuing victims of road accidents as rapidly and safely as possible,” added Karl-Heinz Knorr, vice-president of the German firefighters association (DFV).

Bosch chips ensure that the high-voltage battery is automatically disconnected, so that nobody at the scene of the accident, vehicle occupants, rescue crews, first responders, comes into contact with current-carrying components. The semiconductor devices are part of a pyrotechnical safety switch system, or pyrofuse.

These systems “blow out” whole sections of the cable connection to the high-voltage battery by means of miniature explosive charges, thus quickly and effectively shutting off the power circulation. Bosch semiconductors play a decisive role in these systems.
