These panels are designed to handle the electrical demands of the modern age, with many more appliances and devices demanding energy than ever before. If your home has a 200-amp panel, you likely won’t need to upgrade it before installing a home EV charger. The main exception to this is if your 200-amp panel is already operating at or near its capacity. However, this would likely only be the case if your home has a higher power demand than most.
For homes with 100-amp panels, however, an electrical panel upgrade may be required. Electrical panels with a 100-amp capacity were standard for many decades, as this was sufficient for electrical demands years ago. However, a 100-amp panel is generally unable to handle the demands of most modern lifestyles along with an EV charger.
