E.ON is phasing out Evailable.
E.ON is shutting down its subsidiary Evailable. The company had developed an AI-based software that allowed charging station operators to monitor their actual availability and predict outages. After discussions with potential investors and buyers, no viable path forward was found.

E.ON is ending Evailable’s operations. The energy company confirmed this in response to a query from electrive. “After a thorough review of Evailable’s future prospects, the decision was made to cease the company’s business activities,” an E.ON spokesperson told us. Despite an “innovative product approach” and significant efforts to scale up, it has become increasingly difficult to identify a sustainable path for long-term development amid changing market conditions and strategic priorities.
"Given the challenging market conditions and after evaluating various strategic options, including discussions with potential investors and buyers, no viable alternatives for continuing the business could be identified. Therefore, the decision was made to wind down Evailable," the E.ON spokesperson added.
Upon request, E.ON did not initially provide a specific timeline for the wind-down or details about the future of existing customers. As of now, Evailable’s website is still online, with no signs indicating an impending closure. It remains unclear what will happen to the employees—according to a LinkedIn profile, the company employs between 11 and 50 people—per electrive.
CEO Maren Rehnelt Was Still at LisKon Last Week
Last Thursday, Evailable’s CEO Maren Rehnelt even spoke as a speaker at the Federal Ministry of Transport’s charging infrastructure conference, also known as LisKon, where she introduced Evailable’s AI solution.
Evailable originated from an E.ON innovation. The idea was to apply insights gained from predictive maintenance of power and gas grids to the still relatively young charging infrastructure. In its 2024 annual report, E.ON states that the corporate venture under the Evailable brand was transferred to E.ON One for further scaling. The AI software was designed to detect usage patterns of charging stations and identify deviations from normal operation.
Evailable understands the “true availability” of charging points
The core issue at the heart of this platform is one that many charging station operators are familiar with and goes beyond the traditional uptime metric: a charging column may be technically online yet still unable to facilitate successful charging sessions. Evailable referred to this as “true availability.” To determine this, the system analyzed factors such as OCPP data, charging behavior, and communication errors. Using these insights, the software was designed to identify cases where a column is reported as available but charging sessions regularly fail or occur at significantly reduced power levels.
The reasons why a charging station’s uptime is reported to the operator but actually results in no successful charging sessions can vary greatly: these may include blocked charging spots, faulty card readers, damaged screens, or stolen charging cables. The AI software can also detect cases where a charging station appears “available” yet charging sessions have stopped for two weeks or are only operating at half capacity. The station operator then receives a notification from the Evailable software and can fix the issue.
Another key component of Evailable’s offering is the so-called Health Index. The neural network compared the behavior of a charging station with historical data and other units of the same type. According to Evailable, this should allow potential failures to be detected up to a week in advance — this is also known as Predictive Analytics. For certain types of errors, the software could even automatically trigger a restart of the charging station. As CEO Maren Rehnelt stated in an electrive interview, such automated actions were already carried out more than 100,000 times per month across all customers by the summer of 2025.
Evailable active in multiple countries
Evailable’s business model is aimed not only at Charge Point Operators (CPOs),即充电站运营商。 The company also offers its technology for integration into charge-point management systems — the Danish charging platform provider Virta is one of its partners — as well as to manufacturers of charging hardware. Evailable’s AI software utilizes existing OCPP communication data. According to the company, it already supports more than 75 different charging station models. In September 2025, Evailable also told electrive that it was already serving CPOs in 14 countries.
The closure of Evailable is already the second among E.ON’s subsidiaries in the charging solutions sector this year: In March, Elvah, a data provider for the charging market, had to file for bankruptcy. However, in July, Chargecloud acquired parts of Elvah’s product line.
