Supercharging Station 3.0: Liquid-Cooled Ultra-Fast Charging + V2G + Flexible Charging - A Closer Look at Guangzhou Yanling Industrial Park's New Energy Vehicle Charging Project

The Guangzhou Yanling Industrial Park New Energy Vehicle Charging Project was jointly developed and is jointly operated by Genvict and Guangzhou Public Transport New Energy. Located in Guangzhou Yanling Industrial Park, the site is a benchmark Supercharging Station 3.0 project integrating Vehicle-to-Grid (V2G) interaction, liquid-cooled ultra-fast charging, DC fast charging, managed charging and battery diagnostics. It is also one of Genvict's transportation-energy integration projects. A single V2G connector supports charging and discharging at up to 120 kW; each liquid-cooled ultra-fast charging connector delivers up to 600 kW, and each DC fast charging connector up to 250 kW. The station is equipped with an AI-enabled Energy Management System (AI-EMS), which dynamically adjusts the output of each charging connector based on the vehicle's Battery Management System (BMS), transformer load, aggregate power available from the power cabinet, the utilization of other connectors and cables, the electricity tariff curve, and other factors. The system can also be expanded to integrate low-wind-speed power generation, photovoltaics and energy storage, creating a coordinated source-grid-load-storage system with vehicle-energy dispatch capabilities. This enables optimized charging strategies that balance safety, turnaround time, cost and sustainability.

Liquid-Cooled Ultra-Fast Charging: Charging in Minutes While Balancing Efficiency, Battery Life and Ease of Use

The project is equipped with two 600 kW single-connector liquid-cooled ultra-fast charging terminals, each capable of delivering 75 kWh in no more than 10 minutes (75 kWh/≤10 minutes). The built-in liquid-cooling system uses a closed-loop cooling circuit that reduces the charging module temperature by 10-20°C. Conventional air-cooled equipment must operate at derated output during hot summer conditions; by contrast, this liquid-cooled system maintains full-power output at ambient temperatures as high as 45°C. Temperature variation at critical points is held within ±1.5°C, while vehicle battery life is extended by 20%. The charging cable has a 30% smaller cross-sectional area, while the cable-and-connector assembly is 50% lighter. Together with a pull-assist cable design, this makes the connector easy to handle for a broader range of users, including women, and improves the overall user experience.

V2G Vehicle-Grid Interaction: Bidirectional Energy Dispatch for a Closed Vehicle-Grid-User Value Loop

The project introduces V2G vehicle-grid interaction to reshape the way energy flows between vehicles and the power grid. A 120 kW V2G charger enables bidirectional power transfer between vehicle batteries and the grid. In line with Guangdong's time-of-use tariff patterns, the station can support applications such as peak/off-peak price arbitrage, peak shaving and off-peak load shifting. This creates a three-way value loop among vehicles, the grid and users while opening new revenue streams for the site operator.

Flexible Charging: Centralized Power-Pool Dispatch and Intelligent On-Demand Power Allocation

The project uses flexible charging based on a 'centralized power pool + regulated power output' architecture. A CP800 power cabinet rated at 600 kW manages six 250 kW fast-charging connectors and two 600 kW ultra-fast charging connectors, enabling centralized power dispatch and improving power utilization over time. Using BMS specifications obtained during the handshake between the connector and the vehicle-side BMS, the system allocates output to each connector on demand, accommodating rapid charging requirements across different time periods and vehicle types.

The flexible charging architecture is illustrated below:

Demand Control: Intelligent Microgrid Management for Stable Site Operation and Grid Load

The project is equipped with an iEMC100 intelligent microgrid controller with a built-in Energy Management System (EMS). Built on Internet of Things (IoT) technology, it connects to the CP800 power cabinet and CG120 integrated V2G charger for device connectivity, data communication, power monitoring and energy dispatch. Without adding a new transformer, the system makes full use of the spare capacity of the existing transformer and monitors circuit load in real time. When aggregate charging demand exceeds the grid limit, the controller dynamically adjusts the output of the CP800 power cabinet. This helps avoid the risk of penalties caused by transformer overload, stabilizes grid load, and safeguards both station operations and grid security.

The principle of demand control is illustrated below:

Application Value: Meeting Fleet Charging Needs and Putting Transportation-Energy Integration into Practice

Completed and commissioned in March 2026, the project currently serves primarily ride-hailing vehicles, taxis and light trucks, as well as temporary visitors to the industrial park. Charging activity is concentrated in flat-rate and off-peak periods, with almost no charging during peak hours. The busiest window is the midday flat-rate period from 12:00 to 14:00, which coincides with drivers' meal break. Their ability to complete rapid charging within two hours directly affects the operating range available for subsequent trips, making fast turnaround a core charging requirement. By combining flexible charging with liquid-cooled ultra-fast charging, the project provides charging services tailored to vehicle needs while balancing speed and cost. It has enhanced the reputation of Yanling Industrial Park's supporting services for new energy vehicles and stands as a representative implementation of Genvict's transportation-energy integration vision.

Policy Alignment: Leveraging Guangdong's Peak/Off-Peak Tariffs to Strengthen Project Economics

The project's V2G interaction and managed charging features align closely with Guangdong Province's peak/off-peak time-of-use (TOU) tariff policy, providing a favorable policy environment for technical implementation and commercial viability. Guangdong's TOU tariff is implemented in accordance with Guangdong Development and Reform Pricing Document [2021] No. 331 (粤发改价格〔2021〕331号). The electricity tariff for users whose power is procured on their behalf by the grid operator, excluding government funds and surcharges, is used as the base, or flat-period, tariff. Applicable scope, peak and off-peak periods, tariff ratios and critical-peak pricing are governed by the document. The key rules are as follows:

1. Time periods: A uniform TOU schedule applies across the province. Peak periods are 10:00-12:00 and 14:00-19:00; the off-peak period is 00:00-08:00; all other hours are flat-rate periods.

2. Peak/flat/off-peak tariff ratio: 1.7:1:0.38.

3. Critical-peak tariff: This applies throughout July-September and on any day in other months when Guangzhou's daily maximum temperature is ≥35°C. Critical-peak hours are 11:00-12:00 and 15:00-17:00, totaling three hours per day. The critical-peak tariff is 25% above the peak-period tariff.

4. Pricing rule: Tariffs are denominated in fen/kWh and rounded to two decimal places.

Under these tariff rules, the station can use V2G peak/off-peak arbitrage and managed charging to encourage charging outside peak periods, further increasing the project's economic and social benefits and creating shared value.

Industry Significance: Defining Supercharging Station 3.0 and Setting a Replicable Benchmark

Centered on liquid-cooled ultra-fast charging, V2G and flexible charging, the Guangzhou Yanling Industrial Park Liquid-Cooled and V2G Supercharging Station integrates intelligent demand control with an AI-EMS to redefine the core standard for Supercharging Station 3.0. It upgrades the traditional charging station from a single-purpose charging point into a comprehensive energy service node that combines rapid charging, bidirectional energy exchange, flexible power dispatch and integrated source-grid-load-storage coordination.

The project provides a replicable and scalable model for the development and operation of new energy vehicle charging stations in industrial parks, transportation hubs, logistics parks and similar settings. It also explores a new pathway for deeper integration between new energy vehicles and the power grid. The project offers an important demonstration of coordinated progress in transport electrification and the intelligent transformation of the energy sector, while providing a practical reference for deploying transportation-energy integration in urban infrastructure.
