In the era of fast charging, we all hope to save time for mobile phone charging. Sometimes, when we are in a hurry, we hope that it will be full in two or three minutes. Even though the current fast charge charger, it has to be fully charged in about one hour. Mainly considering the limit of the battery can withstand current, we all know that the charger mainly relies on the current to supply power to the battery, so the magnitude of the current is very important for the battery, then if the charger output current is not enough, Does the battery have an effect?

 

Does the output current of the charger affect the battery?

 

1. For batteries with different capacity, the charging current of the charger is required, because the charging current is too small to charge. Trickle charging can make up the battery capacity, which means that when the battery is about to be full, use trickle charge current, supplement the remaining battery capacity of the battery and then self-discharge of the battery, etc., and if it is charged at the beginning or during long-term charging, use small The current cannot be charged at all.

 

2. At present, most of the chargers on the market use the charger of the complex voltage method, that is, the fast charge, and the charging current is changed. 1.5A indicates that the maximum current is 1.5A, but it will gradually drop to 1A and below with time and battery voltage change, while 1A means that the current starts to decrease from 1A, and the downward trend is uncertain. So you can use 1A instead, but the charging time will be longer. If it is not a poor quality charger, it will have no effect on the battery.

 

3, charger charging has the difference between fast charging and slow charging, generally fast charging has an impact on the battery, but not too obvious for the lithium battery; charging current is usually one tenth or half of the capacity of the lithium battery Yes, for example, a 1000 mAh battery can be charged at 100-500MA, but if the current is too large, the charger will heat up, which may cause a safety accident.

 

Doesn’t the charger’s output current have an effect on the battery? In general, if the current is small, it has no effect on the battery, but it does not charge or go. The current is too large, although it is very fast, it is easy to generate heat. Many people worry about the heat of the charger when charging with the charger. Therefore, the current is preferably within a safe range so that charging is fast and safe.
