Battery Maintenance
EVs utilize two key types of batteries: the 12V battery and the drive battery. The 12V battery powers essential accessories like lights, windows, and the infotainment system. It requires periodic checks to ensure it's functioning properly and typically lasts about 3 to 5 years. Drive batteries, which power the electric motor, come in two forms: lithium-ion (Li-ion) and solid-state. Solid-state batteries, while still emerging, promise longer life, faster charging, and enhanced safety due to their solid electrolyte. Li-ion batteries are standard in most EVs, offering a lifespan of 8 to 15 years with minimal maintenance, mostly involving keeping the battery within optimal charge levels and avoiding extreme temperatures. However, different types of lithium-ion batteries serve different purposes in EV operation. Those differences include:
- 400V Li-ion Batteries: Commonly used in standard electric vehicles, offering a balance of cost, performance, and efficiency. These batteries are slower to charge but are suitable for most daily driving needs.
- 800V Li-ion Batteries: Found in high-performance EVs, these batteries allow for faster charging times and greater efficiency, making them ideal for vehicles that prioritize speed and long-range driving.
Fluid Maintenance
Although electric vehicles have fewer fluids to worry about compared to internal combustion engine vehicles, there are still important fluids that need regular attention, which include:
- Wiper Fluid: As with any vehicle, you’ll need to regularly top off your windshield washer fluid. This is a simple but essential task that ensures clear visibility in varying weather conditions.
- Brake Fluid: EVs use regenerative braking systems, which reduce wear on brake pads, but brake fluid remains crucial for ensuring proper brake performance. It’s important to flush and replace brake fluid at manufacturer-recommended intervals to maintain safe braking performance.
- Coolant: Many EVs, particularly those with high-performance drive systems, use coolant to regulate the temperature of their batteries and other components. Coolant should be checked and replaced as needed, usually at regular service intervals, to ensure your EV's thermal management system is functioning correctly.
Benefits of Hybrid and Electric Vehicles
Hybrid and electric vehicles offer significant benefits when it comes to service and maintenance. One of the key advantages is that electric vehicles have fewer moving parts than traditional gas-powered cars, resulting in lower maintenance costs and fewer repair needs. Hybrid vehicles also benefit from regenerative braking, which reduces wear on brake pads and extends their lifespan. Both electric and hybrid models typically have longer service intervals due to the simplicity of their powertrains and reduced dependency on internal combustion engines. Additionally, the absence of oil changes and fewer fluid replacements in electric vehicles further reduces regular maintenance. These factors combine to make hybrid and electric vehicles more cost-effective to service over their lifetimes, offering long-term savings for owners.

FAQs
Depending on climate and vehicle use, EV batteries typically last between 8 and 15 years.
Yes, the 12V battery in an EV powers essential accessories and should be checked periodically for optimal performance.
EVs require periodic checks of windshield washer fluid, brake fluid, and coolant, depending on the make and model.
To extend your EV battery’s life, avoid exposing it to extreme temperatures, use fast charging sparingly, and try to maintain a charge level between 20% and 80%.
No, EVs don’t require oil changes, as they don’t have the moving parts and engines found in gasoline-powered vehicles.
Brake fluid should be replaced at regular service intervals, typically every two to three years, depending on the manufacturer’s recommendations. For the most accurate recommendation, refer to your owner’s manual.
400V systems are more common in EVs, while 800V architectures allow for faster charging and greater efficiency, primarily in high-performance models.
Yes, coolant levels should be checked periodically, and the system may need to be flushed or recharged as part of routine maintenance.
Yes, wiper fluid needs to be refilled regularly, just as in any other type of vehicle.
Regenerative braking uses the electric motor to slow the vehicle, reducing wear on brake pads. However, brake fluid still requires regular replacement.
