Electric vehicle (EV) chargers require periodic maintenance to ensure optimal performance and safety. As more Dallas-Fort Worth drivers go electric, properly maintaining chargers is essential.

McBride Electric installs countless home EV chargers across DFW. Here is our guide to maintaining both Level 1 and Level 2 chargers to maximize reliability and lifespan.

Level 1 Charger Maintenance

Level 1 EV chargers simply plug into a standard 120V household outlet to provide slow charging. They require minimal maintenance:

  • Check the cord and plug – Replace Level 1 cords if the insulation is cracked or plug prongs are bent or corroded.
  • Inspect the outlet – Ensure the electrical outlet powering the charger is in good condition with no loose, damaged, or overheated components.
  • Keep connections clean – Unplug and re-plug the charger cord periodically to maintain a tight connection free of dirt, grime, or moisture buildup.
  • Update electrical panel – If breakers trip frequently, have us inspect the panel and wiring for needed upgrades to support EV loads.
  • Consider upgrades – Over time, upgrading to a Level 2 charger provides faster charging and may better support electrical needs as home energy use increases.

With their simple plug-in connectivity, Level 1 chargers are maintenance-free beyond basic cord inspection and outlet cleaning. But upgrading to Level 2 may eventually provide better EV charging capacity.

Level 2 Charger Maintenance

Level 2 240V EV chargers have more maintenance requirements:

  • Check connections – Ensure connections at the wall outlet or hardwired junction, the charger, and the EV itself are tight and corrosion-free.
  • Inspect wiring – Periodically look for cracked, loose, or heat-damaged wires leading to the charger from the electrical panel.
  • Clean – Wipe down the outside of the charger unit to remove dirt, particles, and moisture that can damage internal components.
  • Update software – Download and install any software or firmware updates for “smart” Level 2 chargers to improve performance.
  • Calibrate – Advanced chargers may need occasional recalibration to charge EVs accurately and efficiently. Follow manufacturer guidelines.
  • Grounding and GFCI – Ensure the unit is properly grounded. Test any GFCI outlets connected to the charger monthly by pressing their “test” buttons.
  • Prevent tripping – If breakers trip regularly, have your home electrical system inspected for needed updates to handle the high amperage.

Following these maintenance steps for Level 2 chargers allows them to operate safely and efficiently for many years. Contact us if you notice any issues.

When to Call a Professional Electrician

EV owners should not attempt to open or repair a home charger’s internal components themselves. Contact a professional electrician if you experience:

  • Consistent electrical tripping or blown fuses when charging
  • Damage to wiring or connections
  • Cracked or overheated charger casing
  • Corrosion on plugs or ports
  • Error codes displayed on the charger
  • Noticeably slow charging times
  • Unusual noises coming from the charger

Attempting DIY repairs risks electrocution and voiding your warranty. The experts at McBride Electric can safely inspect and fix any EV charger problems. We also offer maintenance contracts for periodic upkeep.

EV Charger Warranty Coverage

Reputable EV charger manufacturers provide warranties covering defects for 3-10 years typically. Make sure you register your warranty and have it transferred if you move.

Warranties differ on which components are covered, so review yours closely. Only use original factory parts for repairs to maintain the warranty. Improper self-repairs can void protection.

If issues crop up during the warranty period, contact the manufacturer to potentially have repairs covered. But have an electrician diagnose problems before claiming warranty coverage.

Protecting Your Investment in Home EV Charging

Proper installation and maintenance ensure an EV charger works smoothly for the long run. Keep your owner’s manual handy and follow maintenance schedules for your model.

Identify and address any electrical issues early before small problems become charger failures. And consider upgrading to Level 2 equipment over time as charging needs grow.
