Munich, June 18, 2026 – The breakthrough for bidirectional charging in the mass market is imminent. In a pioneering collaboration, leading German technology companies The Mobility House and EcoG, supported by EV-Tech—a Chinese high-tech champion specializing in high-voltage energy systems—have successfully developed and certified the ultra-compact, highly efficient 11 kW DC wallbox ChargeLine BiDi for series production. This milestone definitively transforms the electric car into an active component for self-consumption optimization and the broader energy system. Prominent initial OEM customers are already on board, securing the market ramp-up.
What makes this joint approach unique: The ChargeLine BiDi is not a proprietary isolated system. It is strictly based on the latest industry standards ISO 15118-20 and OCPP 2.1 – and furthermore remains compatible with the previous versions ISO 15118-2, as well as OCPP 2.0.1 and OCPP 1.6, to fully guarantee interoperability with vehicles and backends already on the market. This combination of full standard compliance, 800-volt technology, and the possibility for customer-specific customization is available on the market for the first time. This means the ChargeLine BiDi is designed for the vehicle market of tomorrow: By 2030, the majority of high-performance electric vehicles will rely on 800-volt architectures for high efficiency.
This means: Every car manufacturer can replicate this technology for its own customer ecosystem from now on. Every ISO 15118-20-compatible electric vehicle can be charged and discharged at the charging station. Through over-the-air updates, the station can also be updated after purchase to permanently ensure compatibility. This lays the foundation for utilizing millions of vehicle batteries as decentralized energy storage systems, balancing peak loads in the grid, and enabling e-car drivers to achieve significant cost advantages through active participation in the energy market.
The same applies to energy providers: Every provider can connect its OCPP 2.1 backend to the ChargeLine BiDi for charging control. Consequently, both automakers and energy providers can seamlessly integrate the bidirectional wallbox into their existing offerings
As a provider of holistic Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) solutions, The Mobility House is now, for the first time, providing its customers with a fully integrated solution comprising hardware, energy management, and flexibility marketing from a single source.
Sales will be handled through selected OEM partners as well as qualified installation and distribution partners. Interested companies and end customers can register online today and will receive further information on availability, technical specifications, and the respective purchasing channels.
For OEM partners, the ChargeLine BiDi is available immediately for integration testing. For wholesalers, installation, and distribution partners, deliveries will begin in the fall of 2026. Pricing will be communicated shortly by these partners.
Compact 11 kW DC power: Optimally dimensioned for charging and discharging in private and semi-public spaces.
800-volt technology - future-proof from day 1: As a standalone wallbox, the ChargeLine BiDi is fully compatible with 800-volt high-voltage platforms. No compromises in the vehicle portfolio due to a limitation to 400V systems, which will be the minority in the future.
Integrated energy management: V2G and V2H from a single source, from energy market participation to self-consumption optimization. A freely configurable edge computing unit, based on EcoG OS, brings local intelligence directly into the wallbox. With various HEMS cooperation partners, over 80% of all PV, storage, and heat pump combinations on the market are covered.
Reliable & future-proof with EcoG OS: The control technology and the integrated operating system ensure continuous interoperability with V2G-capable vehicles on the market through over-the-air updates and seamless adaptation to regulatory developments. Operated and proven on over 25,000 active charging points worldwide.
Maximum brand compatibility: Full support of ISO 15118-2 & -20 and OCPP 2.1, as well as the previous versions OCPP 2.0.1 and OCPP 1.6, ensures interoperability with already available and future bidirectional vehicles and backend systems.
Cybersecurity according to EU standards: Encrypted vehicle communication, NIS-2 compliant, and EN-18031 certified. Future-proof for the regulatory requirements of the energy market.
Triple-certified for the European market: TÜV-tested according to EN 18031 (cybersecurity incl. OTA and network protection), VDE-AR-N 4105 (grid connection incl. grid code and active power reduction), and IEC 61851-24 (vehicle communication and low voltage directive). The BiDi wallbox is already certified for the German market and will be certified for Austria, Switzerland, France, and the UK before the end of 2026. Further countries will follow.
