Electric and hybrid vehicles
Voltages present in E&HVs are significantly higher (currently up to 650 Volts direct current (dc)) than those used in other vehicles (12/24 Volts dc). In dry conditions, accidental contact with parts that are live at voltages above 110 Volts dc can be fatal. For E&HVs dc voltages between 60 and 1500 Volts are referred to as ''high voltage''.
