Electrical Safety for Electric Vehicles

Insulation monitoring for cars, motor racing and commercial vehicles

There is currently a trend towards energy-saving vehicles with electric or hybrid power. The number of initial approvals is massively on the rise, but the new technology also brings new risks in the event of an accident or an electric/electronic malfunction. Bender ground-fault monitoring devices monitor the complete electrical drive system of electric and hybrid vehicles in the car, offering effective protection against electric shock. These devices, known as isolation monitoring interrupters (IMIs), reduce fire risk and are a vital safety component.

For years, Bender has supplied IMIs to student racing teams to guarantee the electrical safety and proper operation of their pods used in racing competitions. The IR155 is the best-suited IMI for this task because of its small footprint and active measuring capabilities. The latter enables the IMI to measure the pod’s electrical integrity versus the frame before and during operation. Accurate information on potential electrical shorts is vital for sustaining the pod and its possible future passengers during operation. Bender devices are superior to other technologies thanks to their accuracy in measuring resistance during various situations and circuits. The Bender IMI will monitor isolation from the battery, inverters, and converters, into the drive train under all load and temperature conditions.

Insulation monitoring for commercial vehicles

Electric and hybrid power is increasingly used in utility vehicles (lorries, buses, forklift trucks) because it is more economical and efficient than conventional petrol or diesel engines. Bender insulation monitoring devices monitor the complete electrical drive system of electric and hybrid vehicles in the utility vehicle, offering effective protection against electric shock and minimizing fire risk.

Solutions for special vehicles

Bender’s extensive engineering and research teams support the development of prototype platforms and projects. With in-house design, manufacturing, and test facilities, Bender can produce, trial, and approve customized solutions for new build vehicles and charging projects in accordance with customer specifications. Special projects such as racing cars, military vehicles, or vehicle upgrades can be supported with customized variants of existing technologies in finished products or sub-assemblies.
