After the fast charging technology has gradually become the standard charging standard, there are also more fast charging chargers on the market, such as PD chargers, QC fast charging chargers, and various fast charging chargers developed by major mobile phone manufacturers themselves. More and more, it has gradually become the mainstream of charging. We know that the charging speed of fast charging chargers is much faster than that of ordinary chargers, but in fact, in addition to the different speed of chargers, there are many differences in charging methods and performance between the two. Next, let the power adapter manufacturer Take it slow for you.
Ordinary USB chargers generally use constant current charging, and automatically switch to trickle charging after the battery is fully charged. Its advantages are that the circuit design is simple, easy to implement, and the price is low; due to the use of low-current constant-current charging, the heat generation of the battery during the charging process is effectively reduced, which is good for prolonging the service life of the battery. The disadvantage is that the charging speed is slow, because it is a bit difficult for the battery capacity of the increasingly large mobile phone.
fast charger. At present, there are mainly two kinds of fast charging chargers, one is high voltage and small current, and the other is low voltage and high current. Due to the polarization reaction of the battery during high-current charging, the temperature of the battery will rise rapidly. If the battery is fully charged, it may explode and burn. Therefore, the fast charging charger will use a special chip to control the charging process, monitor the battery power in real time, and automatically stop charging once it is fully charged, making the entire charging process safe and efficient. The disadvantage is the unavoidable large heat generation, which has a certain impact on the battery life. In addition, its cost and price are also more expensive than ordinary chargers.
In today's society that is increasingly pursuing efficiency and speed, fast charging chargers are undoubtedly more in line with people's needs. Although fast charging will cause certain harm to batteries, due to the extremely fast replacement of mobile devices, this defect And no one will care. Therefore, power adapter manufacturers predict that in the fields of mobile phones, notebook computers, and tablet computers, fast charging chargers will gradually gain an absolute leadership position.
