Electric Car Maintenance: A Comprehensive Guide for Summer

Electric cars are becoming increasingly popular and become a new trend due to their eco-friendliness, Government regulations & carbon zero policies. However, like any other conventional vehicle, electric cars also require prompt maintenance to keep them running smoothly. But remember, even if it is hot or mild weather; the performance of vehicle will be optimum, if proper measures are taken to maintain the Vehicle.

 

Here are a few tips for better maintenance of your Electric Vehicle in summer and in general.

 

The Battery: The battery is the heart of an electric car. High temperature variations may take a toll on the battery's lifespan, but most modern electric vehicles have active cooling systems in the vehicle, which prevent the batteries from overheating and get damaged. It is always good to park the car in shade or in a covered garage whenever possible to keep the battery cool. For optimal battery performance, it is recommended to check the battery at regular intervals by an expert.

 

While it’s true that EV battery packs will experience heat, the heat produced is effectively managed by the vehicle's battery Thermal Management System. With the proper battery management system in place, EV is able to regulate its own temperature and keep the battery pack from degrading.

 

Tires: Whether it’s an electric car or other regular cars, tire maintenance is always a priority for safety especially during hot climate. The temperature variations can cause tire pressure to fluctuate which affects the car's handling, fuel efficiency, and safety, but proper checking and maintenance on a periodic basis ensure that the tires are in good condition and the vehicles performance is not affected. Always keep your tire pressure within the recommended range.

 

All car owners should rotate their tires regularly, though many skip it. For EV owners, it’s essential to do a tire rotation as per the user manuals because with instant torque, your tires will likely get more action. Electric cars are generally heavier than the conventional cars and tires specifically for electric vehicles are now available in the market, making it an ideal choice to choose from.

 

Brakes: Good brakes are essential for your safety and your car's overall performance. High temperatures can cause brake fluid to boil and damage brake components. Check your brakes regularly and replace brake pads if necessary.

 

Also, Electric cars have an additional feature called Regenerative Braking - It uses your EV’s electric motors to stop your vehicle instead of just making it go. This means that the electric motor that gives you power when you’re driving and can generate power to send to the battery when you’re slowing down. So, every time the leg is lifted off the accelerator or gently apply the brakes in your EV, you’re recovering up to 70% of your forward momentum as electricity to put in the battery. Instead of wasting it as heat that is sent into the air. During summer or when temperature is high, use regenerative braking whenever possible to reduce the stress on your brakes.

 

Cabin Air Filter: The cabin air filter helps keep the air inside your car clean and free from pollutants. Not only are outside smells reduced to a minimum, but also are sub-particles and allergens that could enter the cabin. To keep such a level of comfort and health care, check your filter before summer as it may sometimes cause the filter to become clogged with dirt and debris, reducing its effectiveness. It is always good to change your cabin air filters at least once a year.

 

Coolants & Fluids: To ensure proper maintenance of EV cars, it is important to top up three key fluids at regular intervals or as per the car user manual: coolant fluid, brake fluid, and windshield washer fluid. Coolant fluid is essential for the car's thermal management system and should be checked and refilled periodically throughout the year, with special attention paid to the summer months when heat can cause faster evaporation and reduction of fluid levels.

 

Brake fluid requires the same amount of attention. But EVs' specific braking system leads to significantly less brake fluid degradation, requiring less attention. Brake fluid may need to be checked every one to two years, depending on the make and model of your electric vehicle.

 

To maintain visibility, windshield wiper fluid may need to be added more frequently as per the usage, with consideration for seasonal temperature changes. Choosing between summer and winter blends based on external temperature is recommended.

 

Air Conditioning: Your car's air conditioning system is essential for your comfort during summer. Make sure the system is in good condition and have it serviced if necessary. Also, avoid running the air conditioning at maximum capacity for an extended period to avoid quick battery drain.

 

One of the most beneficial and unique features of current EV cars is Preconditioning. Before driving your electric car in hot weather, you can activate the preconditioning feature to adjust the temperature inside the EV before getting in. This feature allows the user to optimize the performance of electric cars in both hot and cold weather.

 

For example, in hot weather, the EV will adjust its interior temperature before you begin driving. This feature also adjusts the battery temperature, which helps to preserve the overall life and performance of the EV battery.

 

Software Updates: Electric cars have sophisticated software that controls various components, including the battery and motor. Regular software updates are essential to ensure your car's optimal performance. Check for any available software updates and install them if necessary.

 

Other Useful Tips:

EV Charging:

  • Avoid topping up your battery always to 100% or letting it run down to 0%. Ideally, you should try to keep it within 20-80% of charge for maximum battery efficiency.
  • Use Fast charging that let you fully charge within 20-30 minutes to a minimum. While convenient, frequent use of these fast chargers may deplete your battery life if used daily, making charging less efficient.
  • Charge your cars overnight or early morning to avoid battery heat up and to enhance your battery performance. It is always recommended to park the car in shades while charging.
  • The charging cable is essential for your electric car's operation. Keep it safe and damage free, without compromising its safety.
  • To keep track of EV charging at home, we recommend setting a timer.

Driving Mode:

  • Most electric cars have eco-driving mode to preserve the battery charge for extended journeys. In summer, EV batteries tend to consume more charge due to the use of air conditioning and other features. By activating the eco-mode in your EV during hot weather, you can optimize your battery usage and achieve a longer journey.

 

General EV Maintenance Guideline Checklist:*

Monthly:

  • Inspect interior and exterior lights
  • Tyre pressure and wear
  • Windshield washer fluid level
  • Coolant level

Every 6 Months:

  • 12-volt battery connections and clean if necessary
  • Drain holes for any obstructions
  • Cooling system fluid levels
  • Check parking brake
  • Inspect safety warning lights

Every 12 months:

  • Rotate Tyres
  • Replace climate control Filter
  • Multipoint Inspection
  • Check / Replace Wiper Blades

Every 12-18 months:

  • Check / Replace Brake Fluid
  • Check / Replace Cabin Air Filter
  • Inspect Motor and Rotors

Conclusion:

By following these electrical car maintenance tips, you can keep your electric car running smoothly during the summer months. Proper maintenance not only improves your car's performance but also prolongs its lifespan. With a little care and attention, your electric car can continue to serve you for many years to come. In addition to these tips, it is essential to have your electric car serviced by a qualified technician regularly. A qualified technician will check all the components of your car, including the battery, motor, and charging system, to ensure they are in good condition. They will also perform any necessary repairs or replacements to keep your car running smoothly and in optimum condition. It is also important to follow the manufacturer's maintenance schedule. The manufacturer's maintenance schedule outlines the recommended maintenance procedures and intervals for your specific electric car model. Following the manufacturer's maintenance schedule will help you avoid any potential problems and ensure your car is always in good condition.
