Will fast charging affect the life of the battery?

Whether it is fast charging or general charging, it will definitely consume the life of the battery itself. In order to ensure the charging speed, some charging stations use direct current to allow electric vehicles to charge as much as possible in a short time. So the problem naturally arises, because in the case of immature technology, frequent and rapid DC charging will inevitably shorten the battery life. However, the research team from Stanford University and the Stanford Institute of Materials and Energy Sciences at the SLAC National Acceleration Laboratory in the United States, Department of Energy, found that this statement is likely to be wrong. Fast charge and fast release have an impact on the battery itself, but it may not be as serious as everyone thought before, and slow charging does not have that great benefit to the battery. Therefore, the impact of fast charging on batteries must be viewed dialectically. Regarding mobile phones that do not support fast charging, if a high-current or high-voltage charger is used, the device cannot withstand such a high current and voltage, and the battery will naturally have problems. However, as long as you use the original charger or its certified accessories, there is no need to worry. Before leaving the factory, each device will have a series of monitoring mechanisms, and there will also be a standard for the tolerance of current and voltage. As long as this standard is not exceeded, it will not have much impact. It can be seen that the device must support fast charging and the charging cable must be cleared. Not only does the processor support this technology, many protection measures and peripheral equipment upgrades must be matched, which will add a lot of costs and security risks. It is recommended that the original adapter and power cord are the best choice. For example, when using fast charging to charge a mobile phone, the power pool will charge the mobile phone for a long period of time, and it will be in a state of high current to replenish the power of the mobile phone, so compared to ordinary charging, In theory, fast charging will cause more damage to the battery. However, this damage will not affect normal use, nor will it cause the life of the lithium battery to fail to meet the expected use, so if the mobile phone supports fast charging technology, it can be used with confidence. Fast charging technology is mainly divided into two types: high-voltage fast charging and low-voltage fast charging. High-voltage fast charging has been gradually eliminated by the market due to excessive heat generation during charging. As for low-voltage fast charging, because it does not have the above drawbacks, it has been widely used in the market. For example, Huawei mobile phones and OPPO mobile phones all use low-voltage fast charging technology.
