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?

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.

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.

According to standard requirements, starting from August 1, 2026, electric vehicle power supply equipment that has not obtained the CCC certification certificate and marked with the certification mark shall not leave the factory, be sold, imported, or used in other business activities. From November 1, 2026, charging piles without an energy efficiency label will not be able to be sold externally. 以上内容均由AI搜集总结并生成，仅供参考

When BYD announced "1 second to charge 2 kilometers," and Huawei claimed "15 minutes to fully charge an electric heavy truck," super-fast charging technology seemed to become the "savior" of the new energy vehicle era. However, data from the National Energy Administration shows that as of March 2025, among the 3.9 million public charging piles nationwide, the proportion of ultra-fast charging piles is less than 1%; in Guangzhou, out of 200,000 charging piles, only 21 are non-manufacturer-built ultra-fast charging piles, equivalent to one ultra-fast charging pile for every 9,523 charging piles. Why has this "charging revolution" fallen into a dilemma of being "praised but not popular"?

The article analyzes charging pile power distribution matrices, covering implementation methods like semi-matrix and full matrix, and examines cabinet combining, cost reduction methods, and price difference reasons, which is of great significance for design, production and use.

Raise the threshold of the charging industry, optimize the development environment of the industry, and promote healthy development

Promoting large-scale equipment renewal of transport is an important measure to accelerate the construction of a powerful transport country, promote the high-quality development of the transport industry, and build a new development pattern of services, which is conducive to promoting investment and consumption
