18% cost reduction + 15,000 yuan per pile per year! AEAUTO V2G redefines the profit model of liquid-cooled ultra-fast charging
In the ParkLake shopping center, a fashionable landmark in Bucharest, the capital of Romania, the energy center built by AEAUTO is quietly rewriting the European new energy vehicle infrastructure map. In this parking lot, 42 smart devices with bidirectional charging and discharging functions, boasting an average daily peak-shaving capacity of 13,000 kWh, generate an environmental value equivalent to reducing 5.2 tons of carbon emissions. As a commercial project achieving the deep coupling of liquid-cooled ultra-fast charging and V2G, this initiative marks a milestone breakthrough for AEAUTO in energy interaction technology.
Breakthrough technology system builds multi-dimensional advantages.
AEAUTO's independently developed third - generation energy interaction system innovatively integrates liquid-cooled ultra-fast charging and intelligent V2G scheduling technology. The dual-circulation heat dissipation architecture it created (which controls the cable and chip temperatures separately through independent circulation loops) overcomes the challenge of high-power charging temperature control. Combined with the 1500V silicon carbide chip dynamic current equalization technology (which improves stability by reducing the temperature difference of parallel devices by 40%), the charging efficiency is increased to 97%, and the cable temperature is stably maintained below 45°C.
In actual measurements, it has achieved the supercharging performance of "charging for 5 minutes and enabling a range of 300 kilometers", and the average daily service capacity of a single pile reaches 2.3 times that of traditional equipment.
More remarkably, its original AI energy scheduling algorithm accurately controls the battery cycle loss within 0.02% each time by optimizing the charging and discharging curve in real-time (based on a hybrid optimization model of dynamic programming and genetic algorithms). This ensures that the capacity retention rate of the power battery remains at 80% after completing 3,000 deep cycles. This technology successfully alleviates the battery life anxiety in V2G application scenarios, enabling liquid-cooled ultra-fast charging to evolve from one-way energy replenishment nodes to energy routers with autonomous decision-making capabilities.
The global market verifies the commercial value
In the operational practice of the Romanian project, AEAUTO pioneered the construction of a dual-income model of "peak-valley arbitrage + carbon asset operation":
- Economic value: Liquid-cooled ultra-fast charging stores energy during the low-price period at night (0.3￥/kWh) and reversely supplies power to the grid during the peak electricity consumption period during the day (0.8￥/kWh), resulting in an annual increase of 15,000 yuan for a single pile.
- Environmental value: Through the EU carbon trading system, each EV Charger can obtain carbon credits of about 2,000 euros per year, reducing the comprehensive electricity cost of commercial complexes by 18%.
This innovative model also demonstrates strong adaptability in the domestic market. The Shenzhen car-grid interaction pilot project, in which the company is deeply involved, has attracted 17,000 vehicles to participate in grid interaction through the "reverse power transmission subsidy + demand response reward" mechanism (with a net income of 3.6￥ per kWh). The cumulative regulated electricity has reached 88,000 kWh, equivalent to the daily electricity demand of 133 households.
Technology upgrade and user value delivery
In a pilot project in a community in Nanjing, private EV Chargers are connected to the V2G network through the "EV Charger partner plan". Car owners charge during off-peak hours and sell back electricity during peak hours, with an annual increase of more than 5,000￥ per household. The system automatically executes the charging and discharging strategy (based on the priority scheduling algorithm), and users can view the income data in real-time through the APP.
Standardization construction and global layout
AEAUTO's OCPP 1.6J communication protocol (open charging protocol standard) is fully compatible with the EU CCS, CHAdeMO, and GBT interfaces and has passed the CE certification, thus entering the European high-end market.
In the process of participating in the formulation of the GB/T 20234.3 national standard, the dynamic current sharing technology solution proposed by the company forms a strategic counterbalance with Tesla NACS, building a technical moat for the overseas expansion of China's new energy vehicle industry chain.
While the industry is still debating the impact of V2G on the power grid, AEAUTO has provided dual answers using the Romanian empirical project and Shenzhen pilot data. From liquid-cooled ultra-fast charging to the reconstruction of the energy ecosystem, the ultimate goal of this technological evolution is to make each charging pile the smallest energy unit of a smart city.
