EV Smart Charging for Utilities

EV smart charging automatically schedules or adjusts electric vehicle charging based on electricity prices, renewable generation, grid conditions or customer preferences. For a utility it enables intelligent charging tariffs that reduce peak demand while helping customers lower their charging costs.

It lets utilities launch differentiated charging tariffs, increase loyalty through a service customers use daily, reduce grid congestion by shifting charging off-peak, and open flexibility and revenue opportunities — without replacing existing billing systems.

Dynamic charging uses real-time or time-based electricity prices to determine the optimal schedule. The customer defines when the vehicle must be ready and the battery level they need; the platform charges during the most cost-effective periods.

Yes. exnatonCHARGE can prioritise self-generated PV electricity before drawing from the grid, and fall back to the cheapest grid hours when the roof can't cover the session. This raises self-consumption instead of exporting surplus at low feed-in compensation, and runs on existing PV and metering data.

Yes — and this is where most of the addressable base sits. The customer keeps a fixed price per kWh with no exposure to market volatility and no tariff switch, while their charging is optimised against day-ahead and intraday prices so the utility can use that flexibility in its own trading. Participation is rewarded with a bonus, which the utility defines — a fixed monthly amount, or tied to the volume charged under optimisation.

Yes. Smart charging is activated per customer account, so it only appears for customers who have booked it on the portal — not for your whole base. That lets you offer it as a paid or bundled add-on, and those customers are then prompted to connect a vehicle themselves.

The tariff assigned to the customer. Because every product on the exnaton platform is expressed as a tariff, charging follows whatever that customer is actually on — a market-based or spot tariff, a time-of-use tariff, a local or community dynamic price, or a fixed price combined with a flexibility bonus. Nothing has to be configured per customer beyond the tariff they already have, so one platform serves customers on very different tariff models at the same time.

More than 900 models from over 30 manufacturers, with no additional hardware for compatible vehicles. Both battery-electric and plug-in hybrid vehicles are supported.

A compatible vehicle, an internet connection at the charging location, and a tariff the charging can be optimised against. The customer registers the location of their charging point, and optimisation applies within a defined radius of that address — charging elsewhere still works, but the financial benefit follows the tariff of the meter the car actually charges through. A wallbox is optional and only affects charging speed.

Yes. exnaton integrates with existing ERP, CRM, billing and metering systems, including SAP IS-U and SAP S/4HANA Utilities, without replacing the existing IT landscape.

Yes. The solution is available as a white-label web application and can be embedded into existing customer portals using web components, for a seamless branded experience.

Yes. It works alongside dynamic tariffs, time-of-use tariffs, demand-side management and energy communities, so utilities can offer bundled energy products on one platform.

Smart charging provides the foundation for future flexibility services, including vehicle-to-grid, demand response and virtual power plants, as those markets mature.

By integrating the exnaton platform with existing ERP, billing, CRM and metering systems. Utilities introduce intelligent charging products while preserving their current IT investments.
