This was exposed during a recent presentation by the Centro Zaragoza (car repairing studies institute, formed by 80% of Spanish insurance companies), and attended by a group of bodywork garages. At this meeting, a series of guidelines regarding the work on this type of vehicles were explained.
- Disconnect the electric system. This step is necessary to isolate the current from the high voltage battery in order to work safely.
- Use the appropriate oil. These vehicles have high voltage air conditioning compressors. A quality oil must be used for these compressors, since poor quality oils can pollute the system and make it turn off.
- Do not overheat the batteries, which cannot go above 60ºC. It is important to make sure the batteries do not go above that temperature when performing a paint job.
- Check the voltage before starting to work on the vehicle. It is recommended to wait about 10 minutes after turning off the vehicle, before starting to work on it. In addition, it is necessary to check with the multimeter to be sure the voltage is 0.
- Adjust connections correctly. High voltage connections must be connected according to specifications. Any loose cable could cause an accident or even set the vehicle on fire.
- Identify cables. Do not cut a cable without knowing what it is. The cable system might vary from one car maker to another. High voltage cables are usually orange, while blue ones carry between 36 and 42 volts.
