Voltti
Voltti is an electric vehicle charging station designed for urban environments. The station measures 800 mm in width, 400 mm in depth and 1800 mm in height, giving a compact profile. A 100 kWh solid-state battery stores energy and supports 150 kW DC fast charging while lowering demand on the power grid. Power management software adjusts output according to battery status and grid load. Charging is started by connecting a vehicle, and can be monitored through a touchscreen display or a mobile application. The exterior is made of lightweight composite materials with a weather-resistant coating.
