If your smart ED4 (2017 till today) only has the 4.6 kW charger, you can choose the extra that to unlock it to 7.2 kW with the tool. The charger is designed for 7.2 kW as standard. Due to the unbalanced load rules in central Euope, however, it is limited to 4.6 kW. (What is unbalanced load) In order to be able to charge with 7.2 kW, the wallbox must be able to provide at least 22 kW. With the activation to 7.2 kW the vehicle loses the guarantee. (Power can also be set back down to 4.6 kW)
