The first vehicle-grid interaction points are here, and buses are going to start powering the city
2025-04-20
Have you ever thought about it? One day, when you come home from work at the peak, the air conditioner, refrigerator and water heater are all on, and behind that every single degree of electricity may come from the bus you rode during the day? This scene, is becoming a reality.
Recently, the National Development and Reform Commission and other four departments jointly issued a notice announcing the first batch of vehicle-network interaction (V2G) scale application pilot projects, 9 cities, 30 projects selected, Chengdu, Chongqing and other places of public transport, is ready from the "passenger tool" into the urban power grid "mobile charging treasure! ".
Bus + V2G, what can it really do ?
Peak shaving and valley filling: charging at night in the low valley, and sending electricity in the daytime peak. A bus in Chengdu can send about 100 kWh of electricity per day, which is equivalent to the electricity used by 10 households in a day. 7000 vehicles are 7000 "mobile power stations", helping to reduce the peak pressure on the power grid.
Emergency power supply: In the event of hot weather or sudden disasters, buses can be the first to support critical facilities such as hospitals and schools. Chongqing used bus V2G to shed 14 megawatts of load last summer, equivalent to shutting down 10,000 air conditioners.
Resource reuse: Bus batteries have about 20% potential left before they are scrapped, V2G can fully exploit this value and reduce waste.
Economic + environmental win-win: the difference in peak and valley electricity prices brings additional revenue, reduces carbon emissions, and can also participate in carbon trading, creating direct economic returns.
This is not only a technological upgrade, but also a piece of "elastic muscle" for the urban energy system - storing electricity at normal times and releasing energy at critical moments to hold the energy demand of the city's operation, which not only avoids waste of energy, but also allows the whole system to operate more comfortably and efficiently. not only to avoid energy waste, but also to make the whole system run more smoothly and efficiently.
Why now?
The east wind of policy is blowing. The national level for the first time the vehicle network interaction included in the scale of the pilot, the local also supporting the subsidies and tariff concessions; intelligent charging and discharging terminals, V2G charging piles and other technologies have matured; and the large-scale popularity of the new energy public transport, so that there is a natural landing scene for all this.
We have been on the road for a long time!
We have already invested in relevant research before this trend became "obvious".
Industrial lithium batteries: with excellent safety performance, constructing a reliable defence for V2G operation; relying on the ultra-long cycle life, providing strong support for the sustainable operation of the system, which is the core foundation for ensuring the stability and efficiency of vehicle-network interaction.
The energy storage cabinet is the integration of source, network and load storage: as a key energy storage carrier, the energy storage cabinet can efficiently store electrical energy and realise the function of standby regulation; the integration of source, network, load and storage is through the in-depth integration of the power generation side (source), the transmission and distribution side (network), the power end (load) and the energy storage system, to open up the whole chain of energy production, transmission, consumption and storage, and to build a closed loop of energy that is highly efficient and synergistic, and that responds to the situation in real time.
Bus power exchange + V2G charging pile: using advanced digital and intelligent scheduling technology, the energy storage units (such as energy storage cabinets, electric vehicle batteries, etc.) distributed throughout the city are aggregated and managed in a unified manner, forming a "virtual energy pool" with flexible scheduling capabilities, and realising optimal allocation of electric power resources and maximising the value of power resources across regions and time zones. Maximisation.
We believe that the combination of V2G in buses is not only an upgrade of energy technology, but also a new solution of energy storage for urban public utilities.
The city of the future will be different!
Perhaps a few years later, the bus you pass by after work will not only have given you a lift, but also have quietly "powered" your lights, air conditioning, and Wi-Fi.
This is the significance of V2G - to make the city's energy flow, greener, smarter and more resilient. And we are ready to work with more partners to turn this future into a palpable reality step by step.
