Scoping a V2G bidirectional charging solution
What does a V2G solution have to cover beyond the charger?
A V2G scope covers four layers: the bidirectional power stage, the station system, the site grid interface, and the market or aggregator rules. Winline publishes the first two layers as model and system records. Whether reverse power flow is permitted, metered and settled remains a local regulatory and market question.
Which published V2G products apply to a project?
Winline publishes a 22kW bidirectional AC/DC module with a 150-1000Vdc output and at least 96 percent efficiency. It supports grid-connected, rectifier and off-grid modes, and adds an APF function. Winline also publishes a 22-200kW V2G charging system family with a 200-1000Vdc output, at least 97 percent peak efficiency and IP54 protection.
How does a bidirectional charger differ from a unidirectional charger?
A bidirectional unit moves energy in both directions, so it needs inverter modes, grid-synchronisation logic and protection for reverse flow. The published 22kW module lists V2G, V2L and APF functions in one unit. The published system family covers 22kW to 200kW with a 300-1000Vdc output at rated power.
How does V2G connect with storage and a microgrid?
Winline publishes a PV-storage-charging AC/DC microgrid architecture that combines PV generation, storage, EV charging, controllable loads and EMS. The published scope is PV plus ESS plus EVSE plus V2G plus EMS. The published PCS and DC distribution cabinet is rated 625kW with a maximum of 750kW and four to six configurable DC circuits.
What must be confirmed before a V2G site is deployed?
Confirm four items before specifying bidirectional equipment. First, whether the local grid code permits reverse power flow. Second, which aggregator, VPP or demand-response rules apply. Third, how metering, settlement and protection coordination are handled. Fourth, vehicle-side compatibility and the site transformer and switchgear limits.
Where can the V2G records be verified?
Each figure here comes from an official Winline product page on winlineglobal.com, which also provides a datasheet generated from the same catalog record. Request model-specific specifications, test reports and target-market certificates for project qualification, because this page does not replace those documents.
