Electric vs ICE Servicing

As you probably expected, there are several key differences between electric and non-electric car servicing.

Below, I have outlined what I believe to be the key differences:

Factor Electric Car Servicing Non-Electric Car Servicing
Mechanical Complexity Lower complexity with fewer moving parts. Focus on electric motor and battery. Higher complexity with intricate engines, transmissions, and exhaust systems.
Servicing Frequency Less frequent due to fewer mechanical parts and no oil changes. More frequent servicing for oil changes, spark plug replacements, etc.
Maintenance Focus Concentrated on battery health, software updates, and electric drivetrain components. Focuses on engine and transmission maintenance, including fluid and filter changes.
Servicing Costs Generally lower over vehicle’s lifetime. Battery replacement can be costly but is infrequent. Higher due to regular engine maintenance and part replacements.
Diagnostic and Software Updates Relies on software for performance, benefits from periodic updates often delivered remotely. Less reliance on software updates; maintenance is more mechanically oriented.
Environmental Impact Offers a cleaner alternative with reduced need for consumables like engine oils and filters. Servicing involves disposing of oils and filters, contributing to environmental pollution.
