The Era Of Fast Filling Of Electric Cars, Make It Easier For Consumers But It Turns Out That There Is A Risk In Battery

JAKARTA - The year 2025 is predicted to be an "ultra-fast charging explosion year" for new energy vehicles (NEVs). Although rapid advances in fast and ultra-fast charging technologies significantly reduce consumer concerns over travel distances, this has also raised growing concerns: the potential for accelerating battery degradation.

Launching from CarNewsChina, Wednesday, May 7, industry analysis and experience of owners show that the convenience of flash charging may come at a "price" in the form of a reduction in battery life, raising questions about long-term durability and warranty coverage.

Consumers widely believe that ultra-fast charging, like cell phone charging, shortens battery life, although many lack specific data regarding the magnitude of the impact. This concern is reinforced by the high cost of battery replacement, which can reach half the price of new vehicles or even exceed the value of the rest of the car. This presents a difficult choice for owners between changing batteries or the entire car.

Online transport drivers, who rely heavily on ultra-fast charging to maximize their operational time, have observed that fast charging often accelerates the "aging" of batteries. Recent surveys indicate that for online transport vehicles that cover more than 100 kilometers daily and use ultra-fast charging of more than 70 percent of the time, battery health can drop from 100 percent to 85 percent in two years, with decreasing rates accelerating. Research from Tsinghua University shows that batteries frequently using ultra charging above 120kW can shorten their life cycle by up to 40 percent compared to slow charging.

Specifically in China, there are now regulations requiring car manufacturers to provide a minimum guarantee of 8 years or 120,000 kilometers for core components such as batteries. Although most manufacturers comply with this, which allows replacement when battery health drops to 70-80 percent in a warranty period, the practical implementation of this warranty could be complicated.

Many life-long "garancing" policies come with strict requirements, such as requiring genuine owners, limiting annual travel distances, requiring maintenance at official service centers, and limiting commercial use. Some policies exclude vehicles that use ultra-fast charging exceeding certain frequencies, effectively creating guarantee barriers for users who often, including many private owners and online transportation drivers.

Experts advise owners to limit ultra-fast charging to less than 40 percent of their total charging sessions and prioritize slow charging if time allows. They also recommend avoiding ultra-fast charging when the battery is below 10 or above 90 percent of charging conditions, as charging in this range can cause greater damage.
