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.

Recently, many consumers have reported experiencing discomfort such as dizziness, nausea, and ear pressure when riding in pure electric vehicles, and related discussions have repeatedly trended on social media platforms. Some consumers stated that they had no issues working or watching movies during long trips in fuel-powered vehicles, but experienced obvious motion sickness symptoms even during a short 20-minute commute in pure electric vehicles. The discomfort is more pronounced for some people when riding in the back seat.

With the number of new energy vehicles in China exceeding 20 million and the penetration rate of new vehicles stably surpassing 40%, charging facilities have evolved from "optional value-added services" to essential supporting capabilities for catering and hotel businesses. Many operators report that after installing charging facilities, the willingness of new energy vehicle owners to visit their stores has significantly increased, with positive growth seen in guest repeat purchase rates and catering customer satisfaction. However, during the actual implementation phase, many operators face the same core issue: when installing charging piles at the entrance, which is more suitable: 7kW slow charging or fast charging?

As sales of new energy vehicles skyrocket, charging piles, as a "supporting necessity", are seen by many as the next promising industry. After all, cars need charging just as people need to eat. With such a clear demand, the market prospects seem bright no matter how you look at them. But behind the glamorous "sunrise industry", there are many shady secrets. On one hand, car owners are plagued by various charging scams and cry out in frustration; on the other hand, investors are deceived by the dream of "earning money effortlessly" and lose all their capital. How did charging piles, which were supposed to serve the development of the new energy industry, become a "cash machine" for scammers?

Okay, here is the English translation of the provided introduction, aiming to preserve the original tone, technical accuracy, and vivid descriptions: Introduction: Range anxiety has long been one of the biggest obstacles blocking the widespread adoption of electric vehicles (EVs). Imagine this: on a long trip, watching your remaining range steadily drop. You finally find a charging station, only to face a daunting wait of dozens of minutes, or even longer. Does this scenario dampen your enthusiasm for EVs? However, BYD's recently unveiled Megawatt (MW)-level Ultra-Fast Charging technology is attempting to turn the dream of "5 minutes of charging for 400 km of range" into reality through a disruptive "energy replenishment revolution." This is far more than a simple case of "increasing power"; it's an elegant design that integrates energy storage intelligence, cutting-edge power electronics technology, and systems engineering. Today, let's dissect this piece of technological wizardry, akin to solving a classic "water tank math problem," and see how it gently interacts with the power grid while aggressively fueling your vehicle.

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.
