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.

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.

A blogger has revealed that "charging pile manufacturers can adjust the charging coefficient, making car owners seem to have a full charge, but actually only 70% to 80%". For a time, "charging pile power adjustment" has become a sensitive topic among car owners, and many people have begun to suspect that the charging piles around them are hiding something fishy. As car owners, should we worry about the charging piles being "tampered with"? Is the power adjustment of charging piles a technical necessity or an underhand operation? Why do we always feel that the charging pile is charging "virtual electricity"? In this article today, we will start from the technical principles, disassemble the underlying logic of charging pile power adjustment, comprehensively analyze the real reasons for "incomplete charging", and help you avoid the pitfalls of charging.

Why are original charging piles always two extremes: either "given away for free" or "sold at high prices", but never "reasonably priced"?

In the future, liquid-cooled supercharging technology will continue to accelerate penetration. The development and layout of high-power liquid-cooled supercharge technology has a long way to go. This requires the cooperation of car companies, battery companies, pile companies and other parties, only in this way can we better help the development of China's electric vehicle industry, further promote orderly charging and V2G, help energy conservation and emission reduction, low-carbon green development, and accelerate the realization of the "dual carbon" strategic goal.

Daily charging should pay attention to operation details and pay attention to arrangements
