The Mobility House develops V2G solution with Amibox

The Munich-based charging solution specialist The Mobility House (TMH) and the engineering company from Mainz, Ambibox, have entered into a cooperation to jointly develop a Vehicle-to-Grid solution (V2G). The Mobility House contributes the EV Aggregation Platform and Flexibility Trading, which integrate and market electric cars into the energy market. This is intended to enable electric car owners to offer their charging and battery flexibility while parked at home or at work, and thus earn money.

The cars serve as mobile power storage and thus act as a buffer for the power grid. Combined, electric cars could provide more power by the year 2030 than all conventional German power plants, storing renewable energy, smoothing out peak loads, and stabilizing the power grid, according to TMH. To unlock this potential, forces are to be combined.

Hardware meets software

The company Ambibox, which develops solutions for decentralized energy systems, contributes the V2G hardware with the "ambiCHARGE". The compact and cost-effective DC wallbox was specifically developed for bidirectional charging and is available in 11kW and 22kW variants. There are plans to expand the charging offer with a direct photovoltaic input and to integrate other providers such as heat pumps and stationary batteries. If the regulatory adjustments—as planned by the federal government—are implemented in the summer, a scalable solution could subsequently be offered on the market.

TMH points to their more than ten years of experience in developing V2G solutions and numerous pilot projects that have proven the functionality of the technology, including that it does not harm the battery and promotes an efficient renewable energy system. Calculations by the provider show that customers who make part of their electric car battery capacity available as a buffer can achieve revenues of around 650 euros per year, promoting the model.
