The answer to 'why is my EV charger burning smell' is that it could be a sign of a serious electrical issue that requires immediate attention. A burning smell from an EV charger is often caused by an overheating or short circuit in the electrical components, which can be a fire hazard. This could be due to a faulty charger, improper installation, or a problem with the electrical wiring in your home.
Some common symptoms include a burning or melting smell, visible smoke or flames, and the charger not functioning properly. If you experience any of these, immediately stop using the charger, unplug it, and contact a licensed electrician to diagnose and repair the issue. Do not attempt to inspect or fix the charger yourself, as this can be extremely dangerous.
