China wants to use special cars called New Energy Vehicles (NEVs) to help with their power system. These cars can store energy and give it back to the grid when needed. This way, they can save energy and make the power system better. China has made a plan to have more of these cars join the power system by 2030. They also want to set up rules for how these cars can work with the grid and use energy in a smart way. Other companies like Nio are also trying to help with this idea, making their stations act like little power plants that can help the grid too. This is important because it shows that China is moving from old industries to new ones like electric cars and renewable energy. Read from source...

- The article does not provide any evidence or data to support the claim that NEVs can contribute tens of millions of kilowatts to the grid by 2030. This is a very bold and ambitious statement that requires substantial justification.
- The article uses vague terms like "optimize", "contribute", and "regulatory capacity" without defining them or explaining how they relate to NEVs and energy storage systems. This makes the article confusing and unclear for readers who are not familiar with the technical aspects of grid management and electric vehicle technology.
- The article relies heavily on secondary sources, such as the
and a quote from the Standard Chartered CEO, without verifying their credibility or accuracy. This introduces potential bias and misinformation into the article, which could undermine its quality and reliability.

Positive

Based on the article, China has rolled out guidelines to utilize New Energy Vehicles as mobile energy storage facilities. This is part of their bold new energy strategy and they aim to bring NEVs to the forefront of the energy storage system by 2030. The plan includes setting up a technical standard system for vehicle-grid interaction, fully implementing a tariff mechanism for charging during idle hours, and ensuring over 60% of the annual charging power in participant cities and above 80% of the power in private charging piles during idle times by 2030. This shows that China is making progress in the EV sector and shifting from traditional industries to sectors like renewable power technologies and electric vehicles, which indicates a positive sentiment for the future of NEVs and their contribution to the energy grid.
