Do EV Chargers Make Noise?

In normal operation, home EV chargers make little to no noise. Most people do not notice any sound at all once a charger is installed and in use.

Some chargers may produce a very faint hum or click when charging starts or stops. This is normal and usually relates to internal components switching on or off. The sound is brief and does not continue throughout the charging session.

Any noise you do hear is more likely to come from the vehicle rather than the charger. Electric cars sometimes activate cooling systems while charging, particularly in warmer conditions or during higher-power charging. These sounds are typically low-level and temporary.

For outdoor installations, chargers are designed to operate discreetly without disturbing neighbours. Indicator lights may be visible at night, but they are generally subtle and not intrusive.

If a charger produces loud, continuous, or unusual noise, charging should be paused and the issue checked. This is uncommon and would usually indicate a fault rather than normal operation.

In everyday use, home EV charging is quieter than most household appliances and does not create ongoing noise concerns.
