Equipped with the right tools, EV mechanics can perform precise, efficient, and safe repairs on these advanced vehicles.
Key Differences Between EV and Traditional Vehicle Mechanics
Understanding how EVs differ from conventional vehicles is essential for auto workshops:
- Powertrain Structure: EVs use motors and batteries, eliminating the need for traditional engine work like oil changes, spark plug replacements, or exhaust system repairs.
- Battery and Charging Systems: Instead of fuel systems, EV mechanics focus on maintaining the batteries and their charging systems.
- Transmission: EVs typically have single-speed transmissions, which simplify the maintenance compared to traditional multi-gear systems.
- Cooling and Thermal Management: EVs rely on unique cooling and heating systems for batteries, inverters, motors and the passenger compartment. Thermal management can be achieved through heat pump circuits, PTC heaters and coolant based circuits.
- Regenerative braking: One of the ways of increasing energy efficiency is through the use of regenerative braking. This retains more of the energy within the vehicle’s electrical system instead of losing that energy through heat transfer when braking. Therefore the motor plays a significant part in regulating and modulating the speed of the vehicle. This results in the friction brakes working less hard than on a conventional vehicle.
With this specialised understanding, EV mechanics can service, diagnose and repair these vehicles effectively and efficiently.
Certification Programs for EV Mechanics
Certifications validate an EV mechanic’s expertise and enhance employability:
- IMI Certifications: IMI certifications cover the technical and safety aspects of EV maintenance and are respected industry-wide.
- Manufacturer-Specific Programs: EV manufacturers provide specialised training on their models, helping mechanics understand brand-specific technology, often essential for those working in dealerships.
- Flexible Online Programmes: Online certified courses cover EV-specific topics, sometimes offering interactive modules and virtual learning to provide valuable experience on the go.
Certification programs not only validate skills but also ensure mechanics stay current with the latest technologies and repair methods.
Common Issues and Repairs in EVs
Electric vehicles present unique repair needs, including:
- High Voltage Cabling: High voltage cables can fail or degrade over time. This can lead to voltage leakage which can lead to vehicles shutting down until the fault is located and repaired.
- Braking Issues: As the friction brakes operate less than on a conventional vehicle, braking issues due to corrosion and seizure can occur.
- Charging System Troubles: Issues with charging ports or cables can affect charging, requiring both electrical and hardware based checks or on occasion software updates.
- Battery Degradation: With time, batteries can lose capacity, (approx 1 to 2% degradation per year) impacting the vehicle’s range. Battery State of Health is an important metric associated with the used car market.
These are classic areas where expertise in EV mechanics allows workshops to deliver consistent, high-quality service.
Safety Protocols for Working on EVs
Safety is paramount when working on high-voltage EVs:
- Insulated CAT 0 Gloves and Tools: Important for preventing electric shocks and arc flash. Insulated gloves and tools can protect technicians during high-voltage work.
- Battery Disconnection / High Voltage isolation: Before certain tests and repairs, isolating the high-voltage battery ensures a safe working environment.
- Emergency Readiness: Knowing how to manage the different risks associated to Electric and Hybrid Vehicles is important for any EV mechanic. Specialist courses such as The Hazard Management of Hybrid and Electric Vehicles are designed to assist workshops un upskilling their technical teams.
Strict adherence to these (and other) safety measures helps create a secure repair environment, protecting both mechanics and vehicles.
