Safe Interlock Unit (SIU)

The SIU is a standalone interlock measuring electronics unit and provides the functionality of the interlock as an external control unit.
Advantages of the unit
The SIU offers sophisticated monitoring, redundancies, many diagnostic options, improved fault detection and ultimately increased personal safety. The status is communicated to the vehicle control unit or HV battery via a secure CAN interface and a digital output.
The process used is demonstrably secure and offers protection against all common errors. This makes the SIU a fully-fledged replacement for battery-internal interlock monitoring.
