Turn your EV into a power source for your home

Simply put, bidirectional charging allows power to flow both ways. Instead of just drawing electricity from the grid to charge your car, your EV can also feed that energy back when needed – effectively turning your vehicle into a powerful, mobile battery.

This technology delivers several key benefits for your daily life:

• Max out your solar power: Pair ChargeLine BiDi with a Home Energy Management System (HEMS) to use far more of your own solar energy. The wallbox acts as the perfect link, seamlessly tying your EV into your home energy network to boost your self-sufficiency.
• Cut your energy bills: Power your home using electricity stored in your vehicle to directly reduce your household utility costs.
• Get rewarded: Bidirectional charging lets you charge your EV when energy rates are at their lowest. When prices peak, your vehicle feeds power back into the grid, with your earnings credited directly to your monthly electricity bill.
• Support the grid: By acting as a buffer storage device, your EV helps stabilize the public power grid and integrate renewable energy.

The abbreviation "V2" stands for "Vehicle-to":

• V2X (Vehicle-to-Everything): The umbrella term for any system that discharges power from an EV battery to run other equipment or systems.
• V2H (Vehicle-to-Home): Electricity flows directly into your home to power appliances, shielding you from expensive grid prices.
• V2G (Vehicle-to-Grid): Power is actively fed back into the public electricity grid to support energy stability.

To enjoy bidirectional charging at home, you essentially need two core components:

1. A compatible electric vehicle that supports power feedback.
2. Our DC wallbox, ChargeLine BiDi, including its dedicated app.

Depending on your specific setup, a third component may be required:

3. A dedicated V2G electricity tariff from your V2G provider, paired with a smart meter.

Absolutely. With ChargeLine BiDi and a compatible EV, true bidirectional charging works from day one. Thanks to the latest communication standards (ISO 15118-20), the software is fully prepared to support all compatible vehicle models. On the hardware side, it is designed to support a wide range of voltages, effortlessly handling even the newest EV platforms with charging voltages of up to 1,000 V.

No, your standard home connection is perfectly fine. ChargeLine BiDi simply requires a standard 16 A AC supply line. A typical 11 kW AC hookup is more than enough. This make replacing any existing 11 kW wallbox incredibly simple.

Note: Your meter cabinet must support the installation of a smart metering system (iMSys).

Because setting up a bidirectional charging station requires specialised registration and coordination with local grid operators, we work with certified installation partners. Our experts handle both the professional installation and all communications with your grid operator, completely removing the bureaucratic headache from your plate.

At the official sales launch, we will release a compatibility list that we will continuously update. Because ChargeLine BiDi is built entirely on state-of-the-art standards, it will be compatible with a wide range of current and future bidirectional-capable vehicles, while still fully supporting conventional EVs that do not charge bidirectionally.

Yes, you maintain full control at all times. If your schedule changes on the fly, you can pause smart optimization with a single tap in the app and immediately switch to maximum-output charging.

Bidirectional charging is fundamentally ready to go in Germany. If you own solar panels, there is currently one key detail to keep in mind:

• Home use (V2H): You can immediately use your EV's battery power to run your household appliances with zero restrictions.
• Grid feed-in (V2G): Directly feeding power back into the public grid is still subject to some minor regulatory barriers for solar owners. However, a law to fully enable this has already been passed by the Bundestag and is actively being rolled out.

With ChargeLine BiDi as part of our Home Energy Solution, you are already perfectly set up for this future today.

Yes, easily. ChargeLine BiDi accurately tracks all charging data via an integrated, certified MID meter. Depending on your employer’s requirements, you have two simple options for reimbursement:

• Manual tracking (Free): View your charging history directly in our V2G app or export data from the wallbox’s web interface to submit to your employer.
• Automated billing (Convenient): In partnership with experienced backend suppliers, we offer a hands-off, automated solution, covering user identification, tariff tracking, and monthly statement overviews. This premium service involves a minor monthly software fee paid by you or your employer.

The official sales launch for ChargeLine BiDi is scheduled for fall 2026. However, you can register on our waitlist today with no obligation. Signing up guarantees you priority updates and ensures you’ll be among the very first to get access when ordering opens.
