Will the fast charging mode shorten the battery life?

Fast charging mode reduces battery life. In the past, the American automobile media has exposed the problem of excessive battery life aging after electric vehicles are often used for fast charging, especially for pure electric vehicles equipped with lithium-ion batteries. This phenomenon is more prominent. In the United States, users of many pure electric vehicle brands report that their electric vehicles have been used for a period of time, and the power storage has dropped significantly, affecting their mileage. The decline in energy storage refers to the gradual loss of energy storage capacity of the battery after repeated charging and discharging, and the decline of battery function. This problem is also common in our mobile phones and other electronic products. The cause of battery aging is rather confusing, which is a problem that has plagued batteries for a long time. Through inquiry, the use of fast-charging lithium-ion batteries may be the catalyst for this problem. The above-mentioned pure electric vehicle companies also announced official recommendations to prevent the use of fast charging mode, and stated that although fast charging can save a lot of waiting time, the loss of battery life is irreversible. Even with slow charging, the decline of lithium-ion batteries is inevitable, but the process will be relatively slow. Loss of endurance in extreme cold/high temperatures: We all understand the shortcomings of short-range electric vehicles. But the meaning of road anxiety is much more than that. Earlier this year, a study by the AAA Automotive Research Center in Southern California found that the mileage of all-electric vehicles dropped by 60% at low temperatures and 33% at high temperatures. In this experiment, the institute used three pure electric vehicles with three levels of temperature: cold, normal and high. In a temperature control room, equipped with a power meter until the battery is exhausted. According to test data, the battery can last an average of 105 miles at 23 degrees Celsius. But when the temperature dropped to -6 degrees Celsius, the mileage was reduced by 60% to 43 miles. When the test target was operating at 35 degrees Celsius, it dropped to 69 miles, a decrease of about 33%. In fact, today's battery products are affected everywhere at low temperatures. There have also been reports in my country earlier that when pure electric vehicles are driving in low temperature environments, mileage anxiety will increase. Electric taxi drivers in Beijing’s Tongzhou, Changping and Daxing districts reported that the mileage of pure electric vehicles is inherently short, especially in winter, when the mileage is lower than in other seasons. The range of electric vehicles can be said to be the primary technical problem hindering its development, and it is also a threshold that must be faced. As the bottleneck of battery technology is difficult to break through, it is still unclear when battery accessory products can be launched to eliminate distance troubles and jointly reduce costs.
