Will the current introduction of several fast charging methods affect the service life of the battery? The following lithium battery manufacturers Xiaobian to discuss with you!
In fact, the argument about the impact of battery fast charging technology on battery life has been around since the earliest days of consumer electronics, but this argument is really worried by the outside world. It appeared when electric vehicles were just emerging, and charging piles and charging stations were still very scarce.
One thing we can be sure of is that 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, which can make electric vehicles 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, battery life will inevitably be shortened.
However, a team from Stanford University and the Stanford Institute for Materials and Energy Sciences at the Department of Energy's SLAC National Acceleration Laboratory found that this claim is likely to be wrong. Fast charging and fast discharging have an impact on the battery itself, but it may not be as serious as everyone thought before, and the benefits of slow charging to the battery are not so great.
Therefore, the impact of fast charging on the battery should be viewed dialectically. For 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, don't 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 it does not exceed this standard, it will not have much impact.
It can be seen that the device needs to support fast charging, and the charging cable needs to be cleared. Not only the processor supports this technology, but many protection measures and peripheral equipment upgrades must be matched, which will increase a lot of costs and security risks. It is recommended to match the original adapter and power cord is the best choice.
For example, when using fast charging dao to charge a mobile phone, the power pool will replenish the amount of electricity dao to the mobile phone in a state of high current zhi for a long period of time du, so compared with ordinary charging, fast charging will theoretically do more harm to the battery. However, this injury will not affect normal use, nor will it make the lithium battery life not meet the expected use, so if the phone supports fast charging technology, it can be used with confidence.
Fast charging technology is mainly divided into high-voltage fast charging and low-voltage fast charging. Among them, high-voltage fast charging has been gradually eliminated by the market due to the excessive heating of the body during charging. As for low-voltage fast charging, it has been widely used in the market because it does not have the above disadvantages. For example, Huawei mobile phones and OPPO mobile phones all use low-voltage fast charging technology.
