Electric Car Maintenance: What You Need to Know
Electric vehicles (EVs) are known for their efficiency and low maintenance compared to traditional gas-powered cars. However, they still require regular servicing to stay in top condition. If you own an EV or are considering one, here are the key maintenance items to keep in mind.
1. The 12-Volt Battery
Like traditional gas vehicles, most EVs have a 12-volt battery that powers auxiliary systems such as lights, infotainment, and door locks. This battery needs periodic replacement, typically every 3 to 5 years. A failing 12-volt battery can prevent an EV from starting, making it an essential maintenance item.
2. Battery Pack Health and Replacement
The most critical component of an EV is its battery pack. While these battery packs are designed to last many years, they degrade over time. Most EV manufacturers offer warranties covering 8 to 10 years or around 100,000 miles, but replacement costs can be significant—often ranging from $5,000 to $20,000, depending on the vehicle model. Regular software updates, avoiding extreme temperatures, and maintaining an optimal charge level can help extend battery life.
3. Brake System Maintenance
EVs use regenerative braking, which reduces wear on brake pads and rotors. However, brake fluid still requires regular replacement, usually every 2 to 3 years, to maintain proper braking performance.
4. Tire Rotation and Alignment
Electric cars tend to be heavier than gas-powered vehicles due to their battery packs, leading to increased tire wear. Regular tire rotations every 5,000 to 7,500 miles and proper alignment checks can extend tire life and improve efficiency.
5. Cooling System Maintenance
EV batteries rely on cooling systems to prevent overheating. Some vehicles use liquid cooling, which requires periodic fluid checks and changes, usually every 50,000 to 100,000 miles depending on the manufacturer’s recommendations.
6. Cabin Air Filter Replacement
EVs still have cabin air filters that need replacement to maintain air quality inside the vehicle. This is typically recommended every 15,000 to 30,000 miles, depending on driving conditions.
Final Thoughts
While EVs require less maintenance than gasoline-powered cars, they still have important service needs. Regular battery checks, tire maintenance, and brake system upkeep are essential for ensuring a smooth and reliable ride. If you're unsure about your EV’s maintenance schedule, consulting your owner’s manual or a qualified technician can help you stay ahead of any potential issues.
