Why EU sort approval is the lacking lever to make each EV a grid asset.

In 2024, T&E highlighted the potential of Automobile-to-Grid (V2G), and bi-directional charging of Electrical Automobiles (EVs). EVs are ‘Batteries on Wheels’, delivering flexibility advantages for the electrical energy grid, supporting the mixing of extra renewables, and delivering decrease charging prices for EV drivers.

The potential of V2G is more and more recognised, however deployment stays restricted. This briefing examines how V2G can scale and identifies the limitations that proceed to constrain its uptake. It argues that the EU automobile type-approval framework represents a essential coverage lever to allow large-scale deployment.

Within the context of the European Union’s type-approval requirements, T&E helps the introduction of a voluntary ‘V2G-ready’ label on the Certificates of Conformity (CoC) for brand spanking new EVs. This ought to be launched as quickly as attainable. Such a ‘V2G prepared’ label is conditional on the EV assembly the next necessities:

1. Compliance with the identical interoperability requirements (e.g. ISO 15118-20) as these required for the charger (EVSE, Electrical Automobiles Provide Tools) underneath the Various Fuels Infrastructure Regulation;
2. Compatibility of the EV inverter with European grid codes on Necessities for Mills and Demand Response, which ought to be adopted quickly by the European Fee;
3. Integration of an onboard charger able to DC-AC inversion;
4. Sharing of EV battery knowledge, mandated underneath Article 20a of the Renewable Power Directive with third events, together with state of well being, state of cost, energy set level, battery capability, and, the place acceptable, the placement of EVs;
5. Producers mustn’t limit entry to V2G functionality required underneath sort approval by way of paywalls or activation charges. 

By 2032, the necessities underpinning the voluntary ‘V2G-ready’ label ought to be included into obligatory EU automobile sort approval for all new EVs offered.
