Smart Charging

Charging an electric car uses a lot of electricity. The power needed to fully charge the battery could power up to 150 washes. That is why it is important to charge your car at times when electricity prices are lower.

Benefits of Smart Charging

Set your departure time

In the Frank app, you choose when you want to leave. When you connect your car, Smart Charging plans the charging within that time. Your car is charged and ready when you leave.

Use greener energy

When there is a lot of solar or wind power, electricity prices are lower. Smart Charging charges more at these times. This helps you use greener power and save money.

Less pressure on the grid

Smart Charging spreads charging over the day. This helps reduce pressure on the electricity grid. It supports a stable and reliable power system.

The savings shown are based on the performance of our smart chargers in 2025. This provides an indication, but no guarantee, of future savings. The calculation is based on a 70 kWh battery, an average charging session of 56 kWh (from 20% to 100% SoC), and the assumption that 100% of the kWh are charged using smart charging. It is also assumed that the car is plugged in at 5:30 p.m. and unplugged at 8:00 a.m. the following morning, with an average of 3.5 sessions per week at a charging power of 9 kW. The savings shown are regularly updated based on actual results. No rights can be derived from these calculations.
