Electric vehicles (EVs) are becoming increasingly common in American households, and reliable charging stations are essential for their everyday use. As with any piece of technology, an EV charger can experience issues after enough time. Knowing the early warning signs that your home’s charger requires a professional inspection can help you avoid more significant, costly problems.

Frequent Charging Interruptions

If your EV charger fails to complete sessions or repeatedly stops mid-charge, it’s a clear indicator that something might be wrong. Internal component failures, software glitches, and wiring issues can all result in frequent charging interruptions. It may seem like a minor inconvenience, but recurring disruption can reduce the efficiency and lifespan of EV batteries.

Unusual Noises During Operation

EV chargers are supposed to operate quietly. If you hear humming, buzzing, or clicking sounds when the charger is running, it may indicate failing internal components or electrical problems. Such sounds could be a sign of faulty relays, overheating, or loose wiring. Ignoring unusual noises can lead to more severe failures, potentially creating fire hazards.

Overheating or Excessive Heat

An EV charger can often feel slightly warm when operating, but excessive heat is a level of concern that should not be ignored. Overheating can occur due to damaged cables, internal electrical issues, or inadequate ventilation. If your connector or charger gets too hot to touch, discontinue use immediately and consult an electrician. Using an overheating charger can damage both the EV battery and the station.

Visible Damage to Cables or Connectors

Your EV charger’s connectors and cables take the brunt of the wear and tear, leaving them more susceptible to damage. Fraying, cracks, melted sections, and exposed wires are clear indicators that an EV charger needs a professional inspection. Damaged cables are ineffective and pose a risk of electric shock and fire hazards. Even minor wear needs prompt evaluation to prevent accidents and maintain safety and effectiveness.

Inconsistent Power Output

A charger that delivers unusually slow charging speeds or inconsistent performance should have a professional inspection. Slower charging might happen due to the vehicle’s battery management system or your utility provider, but it can also result from internal charger malfunctions. An inconsistent power output can damage an EV battery over time, resulting in expensive replacements or repairs.

Don’t wait for problems to escalate. If you notice overheating, interruptions, damaged cables, inconsistent charging, or strange noises, address them immediately. A timely and professional inspection ensures your charger remains reliable, efficient, and safe for daily use.
