Electrical System

The electrical system is split into two main parts:

  1. The high-voltage system for moving the vehicle.
  2. The 12V dc system for lighting, entertainment and accessories.

The 'high voltage' system is derived from the battery and this could be anything from about 100V to 800V. There are a few manufacturers working with 800V systems though (Hyundai and Kia) due to the safety issues. The main reason for using higher voltages is the ability to use more powerful motors. The public charging infrastructure is not really in place with support for these high voltages though.

Note: Rob designed the electrical system for his Fisher Fury R1 and built a custom wiring loom for it too, so we have no concerns over the design of the electrical system for the OSSEV®. The main areas of learning are around the high voltage system and the CAN Bus.
