Do’s and Don’ts for EV Charger Maintenance: How to clean and care for an EV Charger

Keeping Your Chargers Looking Good and Lasting Long

Electric vehicles (EVs) are becoming increasingly popular, and with that, the need for efficient and reliable charging solutions is on the rise. Whether you have a residential or commercial EV charging unit, taking proper care of it is essential to ensure optimal performance and longevity. At EVSE, we provide a guide through the do’s and don’ts of EV Charger Maintenance, helping you keep your chargers in top shape.

Best Practices for EV Charging Maintenance

Turn the charger off and switch off the isolator: Before cleaning or performing any maintenance on your EV charger, make sure to turn it off and switch off the isolator. This step ensures your safety and prevents any electrical accidents.

Unplug the charger from the car before cleaning: Always disconnect the charger from your vehicle before attempting to clean it. This prevents any accidental damage to the charging cable or the EV itself.

Use a soft, non-abrasive cloth or sponge: When it’s time to clean your EV charger, opt for a soft, non-abrasive cloth or sponge. Avoid using harsh chemicals or abrasive materials that could potentially scratch or damage the surface of the charger.

Dilute water and cleaning solution: Prepare a solution of water and a mild cleaning agent suitable for the charger’s exterior surface. Diluting the cleaning solution prevents any residue buildup while ensuring a thorough cleaning.

Clean externally only: Focus your cleaning efforts on the external surfaces of the charger. Gently wipe away any dirt, dust, or grime that may have accumulated. Be cautious not to apply excessive force or push debris into any crevices.

Thoroughly dry the charger after cleaning: After cleaning, make sure to dry the charger thoroughly. Moisture can cause damage to electrical components, so ensure the charger is completely dry before plugging it back in or turning it on.

Common Mistakes to Avoid in Electric Vehicle Charger Maintenance

Don’t clean the charger while the power is still connected: This should go without saying, but never attempt to clean your EV charger while it’s still connected to the power source. Cleaning the charger with electricity running through it poses a severe risk of electrical shock.

Don’t allow water or cleaning solution to enter the electrical components: It’s crucial to avoid getting water or cleaning solution into the electrical components of the charger. Moisture can cause short circuits or damage the internal circuitry, leading to malfunctions or permanent damage.

Don’t allow water to enter the charging cable: When cleaning the charging cable, ensure that water does not come in contact with the electrical contacts or enter the cable itself. Many charging cables are equipped with protective caps to cover the contacts during cleaning. Utilise these caps to prevent water infiltration.

Don’t use a pressure washer on your charger: Although pressure washers can be effective for cleaning certain surfaces, they are not suitable for EV chargers. The forceful spray from a pressure washer can force water into the electrical components, causing irreparable damage. Stick to gentle cleaning methods to avoid any potential hazards.

Don’t neglect regular maintenance: While cleaning your EV charger is essential, regular maintenance is equally important. Keep an eye out for any signs of wear, loose connections, or unusual behaviour. If you notice any issues, contact a qualified professional to address them promptly.

By following these do’s and don’ts, you can ensure that your EV chargers remain in excellent condition, providing reliable charging for your electric vehicle. Taking proper care of your charging units not only extends their lifespan but also guarantees safe and efficient charging experiences. Keep your chargers looking good and lasting longer with these care and maintenance tips.
