The answer to 'why is my EV charger hot to touch' is that it is normal for the charger to get warm during use. EV chargers generate heat as they convert electricity to charge the vehicle's battery, and this heat can make the charger feel hot to the touch. This is a common and expected behavior and is not a sign of a problem.
However, if the charger is excessively hot, meaning it's too hot to comfortably touch for more than a few seconds, that could indicate an issue that needs to be addressed. Possible causes include a faulty charger, a problem with the electrical wiring, or an issue with the vehicle's charging system. In these cases, it's best to have a professional electrician inspect the charger and charging setup to identify and resolve the problem.
