The answer to 'why is my EV charger hot to touch' is that it is normal for the charger to get warm or hot to the touch during use. This is because the charger is working to transfer a large amount of electrical current to charge your electric vehicle's battery.
Some common causes for an EV charger being hot include: the charger being used to charge the vehicle at its maximum rated power, high ambient temperatures, and the charger being located in direct sunlight or a poorly ventilated area. As long as the charger is not excessively hot, smoking, or sparking, this is generally not a cause for concern.
