Revolution in the power grid: Electric cars become flexible energy storage!

nicht spezifiziert, Österreich - Electromobility has experienced significant progress because the commercial implementation of the vehicle-to-grid (V2G) solution based on the international standard ISO 15118-20 is promoted. According to Econews not only enables this technology to load Electric vehicles (EVS), but also the feedback of energy into the power grid. This contributes to improving energy management and network stability.

A merger of leading companies, including Hubject, Heliox, Accelera by Cummins and Blue Bird, now brings this innovative solution to market maturity. The new V2G application combines the plug & charg functionality with bidirectional charging skills and fully meets the requirements of the ISO standard. This interoperable solution is implemented in particular for electrical school buses that are loaded during the day and in times of low utilization of electricity back into the network.

advantages of V2G

The use of V2G technology has numerous advantages. In addition to relieving the power grids, it also leads to a reduction in operating costs and creates new sources of income for fleet operators. The average EV is parked 23 hours a day, which makes the possibility of use particularly attractive for V2G, as excess renewable energy can be saved and fed back into the network if necessary, such as Switch Ev reported.

In this context, the ISO 15118-20 Standard plays a central role. It enables the bidirectional exchange between the electric vehicle and charging station. A V2G-compatible vehicle can act as an energy supplier in the intelligent power grid, which increases the flexibility of power grid. In addition, the system protects the batteries of the vehicles because it does not have to be loaded with full power. A particularly interesting example is a pilot project in which a Nissan Leaf achieved income of around 1,000 euros per year, according to information from Mobility House .

The functionalities of ISO 15118-20

The latest version of ISO 15118 Standard, ISO 15118-20, supports the plug & charge function. It is sufficient to simply connect the electric car to the charging station, while all relevant processes run automatically. During the charging process, the vehicle and charging station continuously exchange values ​​such as the battery stand and the charging capacity.

In addition, certain steps must be followed in the V2G process: First, the vehicle checks the available load services, followed by an exchange of charging limits and the calculation of a performance profile. The charging process is then controlled by continuous communication between EV and charging station. This dynamic and the intelligent use of the available capacities are crucial for the successful implementation of V2G solutions.

Developments in the area of ​​V2G technology and ISO 15118-20 standards show that the future of electromobility is both innovative and sustainable. The integration of these technologies could be crucial for the implementation of a resilient energy future.
