Berlin, January 30, 2024 – Hubject is thrilled to welcome aixACCT Systems GmbH as the latest partner to join our rapidly expanding Plug&Charge ecosystem. aixACCT successfully cleared the EVSE CHECK audit of their CP-ISO controller. This makes it the first pre-certified hardware partner to join the Hubject Plug&Charge ecosystem.

The Hubject EVSE CHECK empowers service providers in the EV industry to seamlessly integrate with the expansive global Hubject Plug&Charge ecosystem. This comprehensive testing process ensures the verification of ISO15118-2 communication, specifically focusing on Plug&Charge interactions among EVs, EVSEs, CPMS, and the broader Plug&Charge ecosystems.

aixACCT is the first company in the market to provide a pre-certified AC EVSE controller. Using a pre-certified EVSE controller speeds up the development cycle, reduces testing effort and the time to market for a new EVSE significantly. The CP-ISO controller showcases the capability to perform ISO 15118-2 Plug&Charge communication using OCPP 1.6.

Elexon GmbH will be the first customer to use the Plug&Charge-capable CP-ISO from aixACCT with its AC dual charging station "A2".

To ensure the long-term quality of the whole system, the EVSE CHECK is required for every EVSE manufacturer seeking access to the Hubject Plug&Charge environment. Successfully tested EVSE producers are permitted to use the Hubject EVSE CHECK Logo to demonstrate to CPOs and others that it is a verified solution. The company will also be listed on the Plug&Charge ecosystem website: Plug and Charge Ecosystem Overview (

About aixACCT Systems GmbH

aixACCT Systems GmbH has been developing electronic components originally for the semiconductor and MEMS industry since 1995. For the investigation of reliability and degradation, aixACCT has become the technology leader in the segment of piezoelectric components.

The proven requirements of these systems gave rise to the e-mobility sector, in which aixACCT has been developing, producing and selling charge controllers since 2017. This makes aixACCT one of the pioneers among charging station equipment suppliers. More than 35,000 charging points are operated with these controllers throughout Europe.

With the third generation of AC charging controllers, the new "CP-ISO" dual charging controller has the ability to control two charging points with Mode 3 and ISO 15118-2 and communicates via OCPP 1.6 and 2.0.1. In addition to numerous interfaces, it now also has Hubject's Plug & Charge certification for OCPP 1. 6, soon also for OCPP 2.0.1. The "CP-ISO" controller can be added to existing charging stations equipped with our controllers with minimal conversion work, making them future-proof with ISO 15118.

Particularly in charging stations for fleets, our controllers meet all customer requirements tens of thousands of times thanks to their robustness and maximum flexibility. As a development focus, the "CP-ISO" controller will soon also be available in a DC version. The operating software developed in-house represents the common platform for AC and DC charging as well as load management and enables customer-specific adaptations with extremely short development times.

As part of major German and European funding projects, we will be presenting prototypes for vehicle-to-grid (V2G) bi-directional operation based on ISO 15118-20 by summer 2024. This will enable us to offer pioneering technologies ready for production.

Elexon GmbH will be the first customer to use the Plug & Charge-capable charging controller from aixACCT Systems with its AC dual charging station "A2".
