EV 4.3 -- Grounding

EV4.3 Grounding
EV4.3.1 All electrically conductive parts of the vehicle (e.g. parts made of steel, (anodized) aluminum, any
other metal parts, etc.) which are within 100mm of any tractive system or GLV component, and any
driver harness mounting points, seat mounting points and driver controls must have a resistance below
300 mOhms (measured with a current of 1A) to GLV system ground.
EV4.3.2 All parts of the vehicle which may become electrically conductive (e.g. completely coated metal parts,
carbon fiber parts, etc.) which are within 100mm of any tractive system or GLV component, must
have a resistance below 5 Ohm to GLV system ground.
EV4.3.3 Electrical conductivity of any part may be tested by checking any point which is likely to be
conductive, for example the driver's harness attachment bolt, but where no convenient conductive
point is available then an area of coating may be removed.
NOTE: Carbon fiber parts may need special measures such as using copper mesh or similar to keep
the ground resistance below 5 Ohms.
