Electric vehicles share some similarities with their internal combustion engine (ICE) counterparts, but they also require unique maintenance. These vehicles use advanced liquid cooling systems to regulate the temperature of critical components, such as the high-voltage battery pack, power electronics, and electric motor. To keep the system effective and prevent issues, technicians must regularly service the coolant. Checking coolant levels ensures the system can manage the battery temperature. Let’s go over some EV maintenance tips to get your customers back on the road safely.
EV Maintenance Tips: Tire and Brake Care
Tires, brakes, and wipers require regular service regardless of the vehicle’s propulsion system. Due to an EV’s weight, tire replacement occurs more frequently. On average, EV tires wear out 6,350 miles sooner than those on internal combustion engine vehicles, according to data from Epyx’s 1link Service Network platform. This platform helps fleets manage service, maintenance, and repair for over four million vehicles. Technicians should explain the weight differences between an EV and an ICE vehicle to customers. Providing visual proof of the tire’s tread depth helps them understand why their tires wear out faster than expected.
With the tires removed, technicians should inspect the brakes. Regenerative braking reduces the frequency of brake pad replacements. However, even if the brake pad material remains intact, the backing plates may corrode faster due to environmental exposure. Since these components stay on the vehicle longer, technicians must check for signs of wear and rust.
12-Volt Battery Checks
Another frequently overlooked component is the 12-volt battery.
Although it serves the same function as in ICE vehicles, the 12-volt battery in an EV powers various auxiliary systems. Regularly testing, charging, and replacing the battery prevents issues such as electrical system failures, difficulty starting the vehicle, and reduced range. Testing the 12-volt battery follows the same process as with ICE vehicles, but technicians should use a battery tester capable of reading AGM (absorbent glass mat), EFB (Enhanced Flooded Batteries), and flooded batteries. Replacing the battery is straightforward and similar to an ICE vehicle. However, always check the vehicle’s service information to follow the proper safety precautions.
Technician Training and Skill Development
Technicians who invest in specialized training can position themselves as trusted experts in EV maintenance. By developing their skills, they can provide exceptional service. Many organizations, such as ASE, I-CAR, and the BendPak EV Garage video training series, offer EV training programs. A quick internet search will reveal hands-on training options, often in partnership with local technical institutions and training facilities.
