6 FAQs about High voltage inverter safety range

How safe is a traction in-Verter?

The electrical and dynamic safety of a traction in-verter are dominant concerns, notable hazards being the high voltage and current values, and the potential for strong acceleration/deceleration. BorgWarner set out to achieve Automotive Safety Integrity Level (ASIL) D, the top safety level de-fined in the ISO 26262 standard.

What is a functional safety concept for an HV traction inverter?

NXP has developed a functional safety concept for an HV traction inverter that addresses these two points. It defines several system deliverables that customers can use to build their own concept more quickly.

Are traction inverters covered by safety standards?

As vehicle manufacturers pivot to electronic systems like traction inverters, so must the coverage of such systems by our safety standards. While traditional "product safety" refers to the elimination of risk from electrical shock, fire and mechanical hazards, "functional safety" specifically refers to electrical and electronic system hazards.

How safe is an EV HV inverter?

In the case of an EV HV inverter, the definition of the safe state is quite complex due to a high amount of energy flowing into the electrical motor. In some cases this can result in unstable behavior instead of ensuring the safe state that is requested by the system.

What is an HV inverter for EVs?

In the example of an HV inverter for EVs, the functional assumption could be resumed as follows: an inverter is the main traction system of an electric vehicle. It controls energy conversion between an electric source (HV DC battery) and the mechanical shaft of the electric motor, based on torque requested from the vehicle control unit (VCU).
