🚗 Add an electric car — managed by your smart energy system

Smart energy management and an EV are made for each other. Your system already coordinates energy across your home — an EV adds a large flexible load that charges at exactly the right time: solar surplus, lowest tariff, or when your battery is full. See all 205+ EVs in the EV Vehicle Directory.
