Configuration per charge point
Fees, base prices, and tariff assignment are set per charge point—for example when AC and DC economics differ or sites have different requirements.
Dynamic pricing, at your charging stations
React flexibly to market fluctuations. With dynamic pricing, you automatically adjust your charging tariffs to the current market situation – for higher profitability and better grid utilization.
Transparency & control
Make day-ahead prices understandable
You define how your charging prices evolve through the day—with fixed components and variable components from market data. For the market side, we use exclusively EPEX Spot prices

Pricing
Tariffs that fit each charge point, customer, and channel
You configure fees, base prices, and tariff logic per charge point—and choose whether energy is priced dynamically (e.g. via EPEX Spot) or with a fixed rate. Tariffs can be assigned to user groups; dynamic prices work in the driver app and for ad-hoc QR charging alike.
Dynamic or fixed
Per product or offer you decide whether the energy price follows the market or stays fixed—regardless of which user group or product sits behind it.
User groups & tariffs
Assign tariffs and dynamic models to user groups—for example a dynamic driver tariff for contract customers and different pricing for ad hoc or fleet users.
EPEX Spot as the market anchor
For exchange power we use EPEX Spot market information. Variable portions can be bounded with caps and rules in the admin.
Driver app and ad hoc
End-customer prices are consistent in the driver app and for walk-up charging via QR code; dynamic pricing can be enabled in both channels.
Discounts & campaigns
Combine promotion codes and discounts with dynamic prices when it fits your strategy—without overcomplicating tariff logic.
FAQs
Frequently Asked Questions
From per-charge-point setup to dynamic pricing in the app and ad hoc.
What is dynamic pricing?
Dynamic pricing automatically adjusts to external factors such as electricity exchange prices or grid load. This makes it possible to set incentives for charging during off-peak periods.
How are the prices calculated?
Pricing is computed in real time from your configured tariff logic and the EPEX Spot market data you select—typically day-ahead prices, and intraday prices where you configure them. You set price floors and ceilings.
How do customers find out about price changes?
Customers see current prices transparently in the driver app, for ad-hoc (QR) charging, and on the charging station map. Push notifications can highlight particularly low prices.
Is dynamic pricing legally permitted?
Yes, when the price communicated to the customer at charge start—the price that applies to that session—is binding for the ongoing session and does not change during charging (and must not). OB7 supports transparent price display and communication; compliance with the regulatory requirements that apply to you remains your responsibility.
Can I control dynamic pricing for specific customer or user groups?
Yes. You assign tariffs and dynamic models to user groups—for example a dynamic driver tariff for contract customers and fixed or different pricing for ad hoc or fleet users. Dynamic and fixed offers can run in parallel.
Which data sources are used?
We connect to EPEX Spot market data via the MATS API; OB7 is certified as an Independent Software Vendor (ISV) with EPEX Spot. Day-ahead and, where configured, intraday data feed into precise, profitable pricing.
Can fees and tariffs differ per charge point?
Yes. Session start, blocking, and energy prices—and the choice between dynamic and fixed energy pricing—are set per charge point, for example when AC and DC economics differ or sites have different requirements.
Does dynamic pricing work for ad-hoc (QR) charging too?
Yes. You can configure dynamic pricing for the driver app and for ad-hoc payment at the charge point. Customers see the current price transparently before the session starts.
