Study Notes
Low Voltage System (LVS)
- Defined as all electrical circuits of the vehicle in CV (Conventional Vehicle) and every electrical part not part of the TS (Traction System) in EV (Electric Vehicle).
- Maximum permitted voltage between any two electrical connections in LVS is 60 V DC or 50 V AC RMS.
- All LVS parts must be adequately insulated.
- Excluded systems from LVS voltage limit in CV:
- High voltage systems for ignition
- High voltage systems for injectors
- Voltages internal to OEM charging systems designed for
