As temperatures rise, many new energy vehicle owners have noticed a significant "shrinkage" in their cars' range. A vehicle originally labeled with a 500-kilometer range may only manage over 300 kilometers in actual use. What exactly is causing this?

Recently, we've received many private messages from fans complaining: "My electric car can go 500km when fully charged at my home charger, but only 400km when fully charged at a public fast charger. Did the charger manufacturer secretly adjust the power?" "Last time I charged my car to 100% at a fast charger, but it died after less than half the expected range. Is this charger falsely rated?"

With the continuous increase in the penetration rate of new energy vehicles, pure electric vehicles have become one of the mainstream choices for public travel and private commuting, but related riding experience issues have gradually emerged.

To the people's governments of all provinces, autonomous regions and municipalities directly under the Central Government, relevant ministries and commissions directly under the State Council, and relevant central enterprises: The 15th Five-Year Plan for the Construction of a New Energy System has been approved by the State Council. It is hereby issued to you for earnest implementation.

While new energy vehicle (NEV) owners are enjoying the convenience of charging with off-peak electricity at night, a sharp "crack" suddenly rings out, and the charging pile circuit breaker trips without warning — this is a common headache for many EV households across China. According to data from the China Electric Vehicle Charging Infrastructure Promotion Alliance, the total number of public and private charging piles in China exceeded 6 million in 2024, but tripping issues account for as high as 37% of all equipment failure complaints, making it the top pain point affecting user experience.

In recent years, with the continuous deepening and implementation of the "Dual Carbon" goals, coupled with the replacement of heavy-duty trucks with electric models and the support of green trunk transportation policies, the popularization speed of the new energy heavy-duty truck market has once again exceeded the expectations of the entire industry. According to the joint statistics from the First Commercial Vehicle Network and terminal traffic insurance data, from January to June 2025, the cumulative sales of domestic new energy heavy-duty trucks reached 79,200 units, a year-on-year surge of 186%. The market penetration rate in June alone exceeded 26%, hitting a new historical high. The application scenarios cover all categories of commercial fields, including short-distance port transportation, urban municipal sanitation, long-haul trunk logistics, mining area engineering operations, and steel plant sand and gravel transportation.

Since summer began, temperatures in many places have exceeded 35°C, and quite a few EV owners have run into the same puzzle: when you go to an outdoor fast-charging station on a scorching day, just a few minutes after plugging in, you hear the roar of fans from the front of the car. Watching hundreds of amps of current being "poured" into the battery, you can't help but wonder — with the temperature already this high, could fast charging cause the battery to go into thermal runaway? Do we really have to stick to slow charging in the summer?

With the continuous rise in the ownership of new energy vehicles, charging piles, as key energy supply facilities, have their safety and reliability directly related to consumers' lives and property safety as well as the sustainable development of the industry. However, for a long time, the charging pile industry has had the problem of "emphasizing scale over quality", and the market is flooded with a large number of unqualified products, which have become invisible obstacles to the high-quality development of the industry. In December 2024, the State Administration for Market Regulation issued the "Announcement on Implementing Compulsory Product Certification Management for Electric Vehicle Power Supply Equipment", which for the first time included AC charging piles, DC charging piles and other equipment in the 3C certification catalogue.

Energy efficiency rating, in short, is a standard for measuring the energy conversion efficiency of charging piles, with the core focus on optimizing energy utilization and reducing waste. By calculating the conversion efficiency of the device from drawing power from the grid to outputting it to the vehicle, it drives the entire system to evolve in a more efficient and environmentally friendly direction. In terms of functions, the requirements for energy efficiency ratings not only reduce energy loss during a single charging session, but also extend the service life of the equipment, reduce carbon emissions, and ultimately inject standardized impetus into the industry.
