SHOCKS FROM EVS OR CHARGING EQUIPMENT

Good evening everyone.

I am doing some research in to events where any person has received a tingle (perceived shock) or a more serious shock from an EV on charge, or from EV changing equipment.

I would be most grateful to receive any details of such an event? Please email me on info(the symbol for at)astutetechnicalservices.co.uk

Thanks

JP

  • They may still get the odd static related zap however, because  people may become charged with respect to Terra-firma from friction charging (the triboelectric effect) if wearing the right kind of insulating flip flops in dry weather, and then feel something as a short sting if they earth themselves though the car, or anything else for that matter. Not common outdoors in the UK as its not often dry enough, but possible a few days per year.
    Even unplugged, a stationary car is loosely earthed from an electrostatic point of view if the tyres are not factory clean and bone dry.
    However, far higher voltages ~ 100kV  can accumulate while a car is moving on the right sort of surface. Modern up-market tyres include either carbon black or deliberate conductive stripes to mitigate this .- for levels of 'conductive' at the multi megohm level, so things can only discharge slowly.
