AS 5732:2015 Electric vehicle operations—Maintenance and repair
4.6.1 General
After a PEV, HEV, BEV or PHEV has been serviced, it might be necessary to move the vehicle to another part of the workshop or outside of the workshop as parts are ordered. This Clause 4.6 provides requirements and guidance to ensure safety.
4.6.2 Direct drive motor
Some vehicle designs incorporate a permanent magnetic electric motor or generator connected directly to the drive wheels. If this type of vehicle is pushed by hand, current will be generated in the windings with the rotation of the wheels. If the vehicle is in a state of repair and components are disconnected, dangerous high voltage arcs might occur. When vehicle is manually moved, a trolley jack isolating the drive wheels from the floor surface shall be used.
4.6.3 OEM pushing specifications
Vehicles should only be moved at a speed below the OEM specifications. Disconnected HV cables from the motor generator should be insulated with electrical insulation tape to prevent arcing. In certain instances it might be more appropriate to move vehicles around with the use of vehicle wheel jacks which prevent any of the wheels turning during the vehicle movement.
5.1 GENERAL
This Section sets out the procedure where the rechargeable energy storage system (RESS) needs to be removed and isolated from the PEV, HEV, BEV or PHEV. This procedure may be necessitated due to damage to the RESS, which can lead to additional dangers such as leakage of electrolytes.
5.2.1 Safety procedures—Odour
If damaged, high voltage (HV) batteries could give off harmful fumes. If unusual odours are detected, or eye, nose, throat or skin irritation is experienced, designated personnel shall wear the full protective equipment (PPE). Refer to the relevant Safety Data Sheet (SDS) or OEM’s workshop manual for emergency response procedures.
5.2.2 Safety procedures—Fluids
Where leaking fluids or bubbling noises are detected emanating from the HV battery, if it is safe to do so, the vehicle should be ventilated by opening the windows and trunk of the vehicle, so as to prevent the build-up of fumes. NOTE: Vehicles equipped with a high voltage battery cooling system may have water dripping from the HV battery internal evaporator drain. Always refer to the OEM’s workshop manual procedures or emergency response procedures in the event of a fluid leak, fire, smoke or unusual noise emanating from the HV battery.
