> having the high voltage always on is not possible/allowed. I am aware of no law requiring that... Plenty of other high voltage things are always on - for example the outlets in your living room are always live even if you aren't using the room. The electrical danger of your house would be reduced by turning them off when you weren't in the room, but we decided it wasn't worth the complexity/cost to do so for the tiny benefit. Electrical contractors in cars are in the same position IMO. It should be energised once in the factory, and then remain energised for the life of the car. Car service garages can have tools to de-energise and re-energise the HV system if necessary - rather like such tools exist to gas and degas aircon systems. |
