How can I charge two cars at the same time?

You must buy a charger with two plugs or install two separate charging stations. Remember that a solution for charging two EVs simultaneously will likely require upgrades to your home’s electrical system. Otherwise, charging two EVs simultaneously could exceed your home’s electric capacity, causing circuits to trip. If you install equipment that can share the same circuit, it may lengthen charging times but eliminate the need for an electrical panel upgrade.
