Electric motors used in hybrid and electric cars use DC voltages exceeding the normal 12 volts. This can be extremely dangerous when working under the hood. What concerns should I have and how can I safely work on my car?
Every high voltage electric line and connector in a high voltage hybrid is bright orange to warn you. All of the full-Hybrid cars from GM, Ford, Hyundai, Toyota, Honda, and VW/Audi have battery high-voltage systems over 200 volts.
These high voltage wires and connectors are high quality and robust and shouldn’t be a hazard by themselves. If you do have to work on any of the high voltage components, the first thing you do is disconnect the big orange connector at the battery pack and this de-energizes the rest of the system. I would not recommend anyone work on a hybrid repair project without first reading and understanding the factory shop manual. The factories have special training for the technicians in their dealerships for working with the high-voltage systems.
