Why Choose This System

Investing in a V2G charger is not just about charging electric vehicles—it’s about unlocking a recurring revenue stream. For B2B buyers, each unit delivers a projected ROI acceleration of 22-35% via peak shaving and grid frequency regulation (FCAS). Our turnkey PV-Storage-Charging solution integrates our V2G charger with our C&I ESS (100kWh-2MWh), allowing your site to capture solar energy, charge fleet EVs during low-price hours, and discharge back to the grid during high-demand peaks. Key competitive edges: 1 Lowest Levelized Cost of Energy (LCOE) in its class via 96.5% peak efficiency. 2 ISO 15118 + OCPP 2.0.1 compliance for utility dispatch. 3 Hot-swappable power modules for 5-minute MTTR. 4 Global shipping availability from our ISO:9001 factories (15-day lead time). 5 Local Tier-2 O&M support in 40+ countries.

Product Overview & Safety Architecture

The V2G Charger features a dual-stage isolated bidirectional topology, eliminating DC leakage risks. The active liquid cooling system maintains IGBT junction temperatures below 85°C even at full 25kW continuous operation in 45°C ambient, ensuring a system lifetime >10 years. Our multi-layer safety architecture includes: (1) Hardware interlocks – galvanic isolation between grid and vehicle. (2) Active anti-islanding protection (IEEE 1547 compliant) with <30ms disconnection. (3) Integrated BMS handshake library supporting all major LFP, NMC, and solid-state battery protocols. (4) Built-in DC residual current monitoring (RCD Type B). Additionally, the unit houses a Class A+ surge protection device (SPD) and a V0 flammability-rated enclosure. For fleet operators, our cloud-based EMS provides real-time SOC prediction, scheduled bidirectional scheduling, and automated revenue settlement for grid services.

Application Scenarios

Commercial EV Fleets (Last-Mile Delivery & Buses)

For logistics hubs with 20+ electric vans, our V2G charger reduces TCO by 18% annually. Vehicles charge overnight (00:00-06:00) at €0.08/kWh, then discharge 15kW during 18:00-21:00 peak at €0.32/kWh. Each V2G unit generates ~€4,200/year in arbitrage per vehicle.

EV Supercharging Stations with Battery Buffer

Integrate 5-10 units of V2G Chargers with our 500kWh liquid-cooled BESS. Use EV batteries as dynamic buffers to avoid demand charges (saving $20k/month for a 10-stall site) and enable ultra-fast 150kW discharge for emergency DC fast charging without grid upgrades.

Industrial Parks & Micro-Grids

Pair with on-site solar (1-5MWp). During sunny hours, EVs store excess solar; at night, discharge to power office buildings or sell to grid. Our V2G charger supports both islanded and grid-tied operation with seamless <30ms transfer.

Frequently Asked Questions

What is the typical lead time and minimum order quantity (MOQ) for B2B buyers?

For our distribution and system integrator partners, MOQ is 5 units. Lead time: 15 days for sample orders (1-4 units), 30-35 days for container orders (50+ units). We offer DDP shipping to EU, US, AU, and Southeast Asia. Express samples via air freight available in 7 days.

Does the charger support all EV models for V2G? What about Tesla and Chinese brands?

Our V2G Charger uses CHAdeMO 2.0 and CCS Combo 1/2 (ISO 15118-20) connectors. For CHAdeMO, all Nissan Leaf, Mitsubishi Outlander, and BYD models with V2G capability are fully supported. For CCS, we have certified compatibility with Ford F-150 Lightning, Renault 5, ID.Buzz, and all 800V Hyundai/KIA E-GMP models. For Tesla, we support via Tesla CHAdeMO adapter (US/JP) or CCS adapter (EU/NA).

What grid interconnection certifications does the V2G Charger hold?

The unit is certified for bidirectional export under: UL 1741 SA (USA), IEEE 1547-2018, VDE-AR-N 4105 (Germany), G99 (UK), EN 50549-1 (Europe), and AS 4777.2 (Australia). We provide full inverter conformity packages for local utility approval.

How does the 10-year performance warranty work? What is covered for cycle life?

Our warranty guarantees >90% of rated power output for 10 years or 8,000 operating hours, whichever comes first. It covers all power electronics, control boards, and liquid cooling pumps. For the complete PV-Storage-Charging system, we offer a separate line-item warranty on LFP batteries (6,000 cycles to 70% SOH). Local RMA and advanced replacement are available in NA, EU, and APAC.

Can the V2G Charger operate off-grid (island mode) during a blackout?

Yes. With our optional Auto Transfer Switch (ATS) and island gateway, a cluster of V2G chargers can form a micro-grid with our C&I ESS. In blackout, it automatically disconnects from the grid within 1 second and provides single-phase 230V or three-phase 400V backup using parked EV batteries. Minimum requirement: 3x V2G chargers with compatible EVs.
