The answer to 'EV charger buzzing noise' is that a buzzing or humming sound from an EV charger is often caused by electrical interference or a problem with the charger itself. This can be due to issues with the wiring, a faulty component, or compatibility problems between the charger and the electrical system.
Common symptoms include a persistent buzzing or humming noise, fluctuations in charging speed, or the charger cutting out during use. In some cases, the buzzing may be accompanied by flickering lights or other electrical disturbances. The solution typically involves identifying and resolving the underlying issue, which may require the assistance of a licensed electrician, especially if the problem is with the home's electrical wiring or panel.
