How Do I Service an Electric Vehicle?

As electric vehicles grow in popularity, automotive professionals can benefit from the knowledge and skills to effectively repair and maintain these vehicles. 

How to service an electric vehicle

Hybrid and battery electric vehicles introduce hazards into the workplace in addition to those normally associated with the repair and maintenance of vehicles.  

While they may look like a conventional car on the outside, internally, they are quite different. One main difference is the presence of high voltage. Higher voltages allow for higher, more dangerous currents, capable of delivering fatal shock. Additional skills and training are required to safely work on these vehicles. 

Another difference to be aware of is the power source. The power source for an EV has few moving parts. The armature (or rotor) of the motor is the only moving part in the powerplant system, compared to the hundreds found in an internal combustion engine.  

Not only this, EVs come with various features not found on conventional cars such as regenerative braking and the stop-start function which require additional safety protocols. Even the operation of the auxiliary systems differ. 

With the unique parts and servicing requirements of electric drive vehicles, it is crucial that individuals are appropriately trained before performing any maintenance, diagnosis, or repairs. 

How to become an electric vehicle mechanic

Those aspiring to become an electric vehicle technician must have prior training in one of the following qualifications: 

  • AUR30320 – Certificate III in Automotive Electrical Technology or equivalent  
  • AUR30620 – Certificate III in Light Vehicle Mechanical Technology or equivalent  

Individuals can then undertake accredited training to gain the necessary skills to service and maintain electric drive vehicles. You will be assessed in several units including how to depower and reinitialise electric drive vehicles, how to diagnose and repair high voltage rechargeable energy storage systems, and how to diagnose and repair system instrumentation and safety interlocks.
