Top 10 Differences in Servicing Between Internal Combustion Engine (ICE) and Electric Vehicles (EVs)

As the automotive industry undergoes a rapid transformation towards electric mobility, the maintenance and servicing requirements for vehicles are also evolving. In this blog, we will explore the top 10 differences in servicing between internal combustion engine motor vehicles and electric vehicles. Understanding these distinctions will help vehicle owners and mechanics adapt to the changing landscape and ensure optimal performance and longevity of their vehicles.


1. Powertrain Complexity:

ICE Vehicles: Internal combustion engines consist of multiple moving parts, complex systems such as transmissions, and exhaust systems that require regular maintenance and repairs.

EVs: Electric vehicles have a simpler powertrain with fewer moving parts, eliminating the need for tasks like oil changes, spark plug replacements, and timing belt repairs.


2. Battery Maintenance:

ICE Vehicles: Traditional vehicles do not have a high-voltage battery, reducing the need for battery-specific maintenance.

EVs: EV batteries require periodic maintenance, capacity testing, cell replacement, and software updates to ensure optimal performance and longevity.


3. Specialised Training:

ICE Vehicles: Mechanics require knowledge of traditional internal combustion engines and their associated systems.

EVs: Specialised training is necessary to work on electric powertrains, battery systems, high-voltage systems, electric motor maintenance, and software diagnostics.


4. Fluid Servicing:

ICE Vehicles: Regular fluid changes for engine oil, coolant, transmission fluid, and power steering fluid are common requirements.

EVs: Electric vehicles have fewer fluids to service, typically limited to coolant for battery thermal management and brake fluid.


5. Exhaust System:

ICE Vehicles: Exhaust systems in traditional vehicles require regular inspections, repairs, and emission testing.

EVs: Electric vehicles produce no tailpipe emissions, eliminating the need for exhaust system maintenance and emissions testing.


6. Software Updates:

ICE Vehicles: Software updates are typically not required for traditional vehicles.

EVs: Electric vehicles rely heavily on software systems for functions such as regenerative braking, power distribution, and battery management. Regular software updates and diagnostics are essential for optimal performance.


7. Charging Infrastructure:

ICE Vehicles: Traditional vehicles do not require dedicated charging infrastructure.

EVs: Electric vehicles depend on charging stations for refueling. Mobile mechanics may need to service and maintain charging infrastructure, including electrical diagnostics and connectivity issues.


8. Motor Maintenance:

ICE Vehicles: Internal combustion engines require regular maintenance and repairs for components such as belts, pulleys, and timing chains.

EVs: Electric motors have fewer wearable components, resulting in reduced maintenance needs.


9. Noise, Vibration, and Harshness (NVH):

ICE Vehicles: ICE vehicles produce engine noise, vibrations, and harshness that require inspections and repairs.

EVs: Electric vehicles are quieter and have lower NVH levels, reducing the need for NVH-related maintenance and repairs.


10. Safety Considerations:

ICE Vehicles: Mechanics must adhere to safety precautions related to fuel, exhaust emissions, and ignition systems.

EVs: Additional safety considerations come into play when working with high-voltage systems and battery packs. Proper training and precautions are vital.


Conclusion:

As electric vehicles gain popularity, the servicing requirements for vehicles are undergoing significant changes. From simplified powertrains to battery maintenance and software updates, mechanics and vehicle owners need to adapt to these differences. By understanding the unique servicing needs of electric vehicles and investing in specialised training and tools, the team at McMahon Mobile Mechanics can ensure efficient and effective servicing for the emerging electric mobility landscape.
