PV-optimized charging extends the reev EMS with cloud-based, forecast-driven charging optimization. By taking expected PV yields and on-site energy demand into account, charging processes are planned in advance to maximize the self-consumption of solar power.

PV‑optimised charging is activated directly within the reev Platform (Menu Energy Management Sub-menu Configuration). A dedicated activation flow guides you step by step through the configuration and collects all necessary site and PV data. Afterwards, adjustments may be made at any time.

In contrast to Local PV Integration, no hardware installation or local metering setup is required – making the start especially simple, fast, and fully digital.

The system takes into account:

Based on this information, reev EMS schedules charging sessions so that vehicles are charged on time while maximizing the share of solar energy used.

This makes PV‑optimised charging ideal for sites that want to use their solar energy not only during moments of surplus but to actively plan charging operations ahead of time according to expected solar generation.

In the reev Platform (Energy Management → Overview), three additional key metrics are displayed after activation:

The use of the reev app by your drivers is an important building block for PV-optimized charging. It helps fully unlock the savings potential of PV integration while ensuring high user satisfaction.

The Charging Schedule* links drivers’ charging preferences with the reev Energy Management System (EMS). Based on departure time and desired target charge level, the system automatically plans charging sessions and intelligently shifts them to periods with PV surplus.

For more information on the Charging Schedule, see: reev EMS | Charging Schedule for Your Drivers

Activation can be done directly via the reev platform – under the menu item Energy Management. A prerequisite is that the reev EMS is already activated.

The PV-optimised charging feature is currently included in the reev Business and reev Enterprise licenses.

For all reev Pro and Compact accounts, a free trial phase will be available after launch until July 15, 2026. After this period, continued use is expected to cost approximately €3 per charging point per month. The contract term is 1 year.

Yes. The current test phase for reev Pro runs until July 15, 2026, and can be cancelled at any time before that date. From July 16, 2026, the feature becomes part of the paid reev Pro or Compact license with a one-year contract period.

No, demand-based charging is always ensured.

For registered drivers with a charging schedule set up in the app, the system intelligently optimises the charging process so that the vehicle is ready at the desired time with the desired battery status.

If no schedule is stored (for example: ad-hoc charging or eRoaming), the charging session starts immediately, without considering current PV generation.

Not necessarily. However, only registered drivers who start the charging session via the reev app and set a charging schedule (desired battery level and departure time) contribute to PV optimisation.
If charging is started without the app (e.g., via RFID), standard load management will apply, but without dynamic shifting based on PV generation.

When the weather is poor, the system automatically draws grid power to meet the desired charging schedule. The EMS uses forecast-based data (e.g., weather predictions) but continuously adjusts to real-time measurements, ensuring that the vehicle is still fully charged on time.

The reev EMS continuously recalculates energy distribution.
When new vehicles start charging, the total energy demand is updated and the distribution of available PV power is dynamically optimised across all active charging points.

Currently, PV optimisation is configured per site – it applies to all charging points within the site’s energy management setup. Selective activation for specific users is not supported. However, optimisation still depends on whether a driver has set up a charging schedule in the app.

No, there is no fixed minimum threshold. The reev EMS can also charge when the available PV power is below the charging station’s or vehicle’s minimum charging capacity. In such cases, grid power automatically supplements the missing energy, ensuring stable charging while maximizing the use of PV energy whenever possible.

Yes. PV-optimised charging can also be used when an energy storage battery is installed. Charging sessions are shifted to times with predicted PV surplus, without conflicting with the battery. Currently, the battery’s own charging and discharging behavior is not yet directly considered in optimisation.

At this stage, manual correction or API submission of estimated PV production is not available. However, our team is working on further developments in this area.
