Let’s look at some of the key factors you’ll need to consider to know if your electrical panel will support your EV charger.

Existing Service Size

Most modern homes have a 200-amp electrical panel, although some use a 100-amp electrical panel. If you have a 200-amp electrical panel, your property is likely prepared for an EVSE charger, so you may not need to upgrade your electrical panel. However, you’ll need to ensure your electrical panel has adequate space for a dedicated line for a level 2 charger. If you have a 100-amp panel that’s operating near its capacity, the panel may not be able to support your EV charger. You’ll need to call an electrician to perform a service panel upgrade.

Household Electrical Load

You’ll also need to consider your household electrical load to determine if your electrical panel will support your EV charger. Electrical load varies from home to home, so there’s no one-size-fits-all solution when it comes to EVSE charger installation. If you are unsure about your home’s electrical load, call a nearby EVSE installer to perform an electrical load calculation. This calculation is done in consideration of your home’s square footage, list of electric appliances, and the existing service size. They will perform calculations to find out how many amps are already in use and how much you have to spare. This will help you decide if you need an electrical panel upgrade.

What Can I Do If My Electrical Panel Will Not Support My EV Charger?

If an electrician determines that your electrical panel will not support your EV charger after performing an electrical load calculation, they will either upgrade your electrical panel or install an energy management system. Electrical panel replacement is a worthwhile investment as it increases home safety, comes with additional circuits to support more electronics and appliances, and ensures more consistent power. Besides, upgrading your electrical panel reduces maintenance costs, thereby saving you money in the long run.
