Protective measures against electric shock in electric vehicles

Threatening electric shock hazards imposed by electric and hybrid vehicles can be minimised through new product development for Formula 1 Bender develops unique measurement methods

Protective measures against electric shock in electric vehicles have not received appropriate attention so far.

The Formula 1 accident at BMW showed the life threatening danger imposed by high battery voltages in electric and hybrid vehicles. The generally accepted and widely used measurement methods for insulation monitoring could not ensure adequate protection against electric shock and danger of fire when tested under varying hazardous conditions.

Bender has successfully developed a technically superior solution for insulation monitoring of the complete electrical drive system of electric vehicles: the new insulation monitoring device
A-ISOMETER® iso-F1.It only weighs 50 g and is already used in Formula 1 racing cars of the 2009 series.

It has shown an excellent performance and has successfully passed every test situation. Homologation was granted by FIA (International Automobile Federation).

The unique insulation monitor protects the driver, the mechanics and all other people involved against the hazards of electric shocks in any situation of the race and under all weather conditions. Furthermore, the risk of fire by sparks is significantly reduced.

Bender with its headquarters in Grünberg, Hesse; and representatives in more than 60 countries, is market leader for monitoring systems promoting electrical safety. For more than six decades Bender produces first-class products that enjoy an excellent reputation in almost all industries.

Besides a wide product range Bender also offers branch-specific solutions, such as for hospitals, mining, automation, chemical industry, engineering, ships, submarine, railway technology, as well as for wind and solar energy. With the A-ISOMETER® iso-F1 the company was able to develop a further special application for the growing market of electric and hybrid vehicles.
