Tap's Charge Control features enable you to control the amount of power available to drivers at a given time. Tap offers different Charge Control programs depending on your use case.
Not every charger supports Tap Charge Control. You will get a warning in app if your charger is not supported.
A Charge Control program is applied to all chargers at a given location.
The available Charge Control programs are as follows:
- Power scheduling: Set a schedule that governs the maximum amps per charger.
- Dynamic tariffs (NETHERLANDS ONLY): Unlock dynamic energy tariffs on your chargers and save on your energy bill.
Additionally, you can set a Random Start Delay, which can work on top of any Charge Control program.
Random start delay: Enforce a random start delay to support the grid.
Power scheduling
For each of your locations, you can set a schedule that governs the maximum amps per charger.
Setting a power schedule
- Location > Charge control
- Set your Charge Control program to Power scheduling
- Set a default rate. This is applied when an active schedule has no interval configured during a given time period.
- Create a schedule by adding new intervals and setting a maximum rate for each interval.
- Save.
Enabling Driver Override
As an owner, you may want to give drivers the option to override your power schedule. For example, if you are using the power schedule to follow your peak and off-peak tariff, you can give drivers the option to opt-out of the schedule and charge immediately at the higher tariff.
- Location > Charge control
- If you have already set a Power Schedule and saved it, a toggle will appear to enable override. Turn this on.

Dynamic Tariffs
If you have a dynamic energy tariff, this Charge Control program will apply an algorithm to charge at the cheapest possible time.
The Dynamic Tariffs program is currently only available in the Netherlands.
How Dynamic Tariffs work
The Dynamic Tariffs program tracks the spot market price. Since retail dynamic energy contracts also follow the price, Tap is able to accurately make decisions on the cheapest times to charge.
Dynamic Tariffs work best when the drivers car is connected to Tap so that we know the battery state of charge. However, it is not necessary. This feature can always work, whether or not the car battery level is known. For information on how a driver can connect their car to Tap, see this article.
To learn how drivers (including yourself) can take advantage of the Dynamic Tariffs you have set at your location, see this article.
Enabling Dynamic Tariffs at your location
- Location > Charge control
- Set your Charge Control program to Dynamic Tariffs.
- Save.
Random start delay
You can enforce a random start delay to support the grid. For example when you have a power schedule configured that might have many vehicles turning on at the exact same time.
Setting a random start delay
- Location > Charge control
- Switch on Random start delay
- Enter maximum delay in seconds.
- Save
