The new optional 22 kW on-board charger with fast charging function permits three-phase charging at public charging stations and at a wallbox. It enables the high-voltage battery to be charged from 10 to 80 percent in under 40 minutes. It will be available from May and will cost 840 euros.
All smart vehicles with electric drive come with a 4.6 kW on-board charger as standard. This provides for fast recharging of a drained battery – in less than 3.5 hours at a wallbox, in under six hours at a domestic wall socket (10-80 percent in each case). The "smart control" app enables convenient remote monitoring of the charging process and remote control of functions such as intelligent charging.
From May 2018, a particularly powerful 22 kW fast charger will be available as an option in Europe. This makes it possible for the smart fortwo (combined power consumption of 22 kW on-board charger with fast charging function: 13.5 – 12.9 kWh/100 km; combined CO2 emissions: 0 g/km), smart fortwo cabrio (combined power consumption: 13.5 – 13.0 kWh/100 km; combined CO2 emissions: 0 g/km) and smart forfour (combined power consumption: 14.0 – 13.4 kWh/100 km; combined CO2 emissions: 0 g/km) to be charged in a considerably shorter time: in less than 40 minutes (10-80 percent) when local conditions permit three-phase charging. Furthermore, smart offers a wallbox as a special item of equipment.
