In the field of electric mobility, there are three tariff models that can be used to calculate the charging price:
Activation fee: Partner stations often charge an activation fee, as the roaming platform or station operator charges a usage fee each time a charging process is started.
Consumption-based tariff: Price per kWh.
Time-based tariff: Price per minute. Time-based tariffs are often used for fast charging stations to prevent long parking times.
