V2G Service Design — The Malakhatka Blueprint

Research increasingly frames V2G not as a technology problem but as a service design challenge — a complex end-to-end service system requiring coordination across users, service providers, and grid actors. A 2026 Chalmers/Polestar/Vattenfall/Göteborg Energi/Svk co-design study (funded by Vinnova, project PAVE — Implementation of Vehicle-to-Grid Services in Sweden; Source - Så Kan V2G Gå Från Projektform Till Marknaden (2025)) developed a V2G service blueprint through 18-participant stakeholder workshops, mapping the full service lifecycle across nine phases. (Source - Malakhatka et al V2G Service Blueprint Sweden (2026))

PAVE is the same effort as the pilot referenced on Vehicle-to-Grid — the same Vinnova grant, the same partner list (Polestar, Vattenfall, Göteborg Energi, Svenska kraftnät, Easee, Chalmers). See Vehicle-to-Grid › Swedish pilots for the pilot’s operational status and timeline. The project’s economics strand puts a number on what the dead zone delays: a Chalmers optimisation of one Gothenburg household finds that spot, FCR-N and FCR-D trading could cut the annual electricity bill from about 32,000 SEK with direct charging to about 2,300 SEK, most of it from FCR-N, under idealised assumptions such as direct market access for a single car (Source - Ramasan et al To V2G or Not Residential (2026), a preprint).

The nine-phase service blueprint

The pre-qualification dead zone

A profound service-delivery friction identified by the study: hardware commissioning (Phase 5) takes 3–6 months; the subsequent Test Pre-qualification process (Phase 6), in which the Aggregator and BSP verify the EV/EVSE meets Svenska kraftnät‘s technical requirements for FCR/aFRR participation, adds a further 1–5 months. Early adopters bear significant capital expenditure (bidirectional wallbox) without the immediate ability to recoup it through flexibility markets during this window. Proposed remedy: digital twins of local grid segments enabling “one-click” pre-qualification at the contracting stage.

Service design challenges

• Contractual complexity: V2G agreements involve Aggregator, Energy Supplier, BSP, and installer obligations across multiple documents. Workshop participants consistently identified simplicity and transparency as prerequisites for user adoption.
• Divergent value propositions: users primarily want financial clarity and battery state-of-health (SOH) monitoring; abstract grid benefits (CO₂, system stability) are far less persuasive. V2G interfaces must lead with financial projections and battery health — not grid contribution metrics.
• Fuse overload risk: Aggregator backstage signals that fail to synchronize with local building loads can cause V2G discharge to exceed the household main fuse capacity, triggering local outages. This “Incorrect Load Balancing” risk requires local fail-safe mechanisms or smart inverters with autonomous load shedding — distinct from the LV network stress at high fleet penetration documented on Vehicle-to-Grid › LV network impacts.
• Trust as infrastructure: 18% of potential users cite data privacy and cybersecurity as barriers. Immediate visual or haptic micro-feedback confirming that backstage commands have been received is essential to counter the “black box” perception of automated V2G services.
• Pause vs termination: binary service termination triggers full TSO/aggregator deregistration. A “Pause” or “Vacation Mode” — maintaining asset registration during inactivity — preserves historical battery health data and eliminates re-onboarding friction, improving long-term fleet retention.
