Chengdu "Mobile Power Bank" Vehicle-to-Grid (V2G) Pilot Project Introduction

Project Background

On April 14, China's National Development and Reform Commission, National Energy Administration, Ministry of Industry and Information Technology, and State Administration for Market Regulation jointly announced the first batch of large-scale V2G application pilot projects. After rigorous evaluation and multiple rounds of selection, Chengdu's "Mobile Power Bank" V2G pilot project was successfully included in the national list of first V2G pilot projects.

V2G Technology Overview

V2G (Vehicle-to-Grid) is a bidirectional interaction technology that transforms new energy vehicles from mere "power consumption devices" into "mobile power banks" capable of supplying electricity back to urban grids. During charging, vehicles draw power from the grid, while during discharging, they can reverse the flow to supply electricity to both the grid and buildings, effectively alleviating peak load pressure on the power grid.

Application Scenarios

When implemented, this technology will enable Chengdu's buses to function as "giant mobile power banks". These buses can utilize their onboard power batteries to supply electricity back to power-consuming devices. During peak electricity demand periods, Chengdu's bus fleet could leverage some of its new energy buses - with battery capacities equivalent to the daily electricity consumption of 30 households.

Through the V2G intelligent dispatching system, during regional power shortages, Chengdu's 7,000+ buses can transform into "urban mobile power banks," quickly responding to form numerous "energy storage units." These can provide emergency power supply for critical facilities such as hospitals, government offices, and emergency electric vehicles.

Implementation Progress

Currently, Chengdu Public Transport has completed construction of the Gaoshengqiao Comprehensive Energy Demonstration Station, equipped with 2 V2G charging piles. In collaboration with battery manufacturers and automakers, they have preliminarily completed technical upgrades for 50+ long-range buses, laying the groundwork for comprehensive charging and discharging operations.

Other Related Projects

In addition to the "Mobile Power Bank" project, Chengdu has two other V2G projects selected for the national pilot program: the "Two Areas, Three Centers" Intelligent V2G Pilot Project and the "Transport-Energy Integration" Virtual Power Plant Ordered Regulation Large-scale V2G Pilot Project.

According to TopUsedCars.com reporter Calvin Zhang, these initiatives demonstrate China's leadership in innovative energy solutions for the automotive sector, offering valuable insights for international partners in the Middle East and Africa looking to adopt similar technologies.
