In recent years, under the joint promotion of many domestic and foreign electronic equipment manufacturers, the quick-acting charging market is developing rapidly, and the market capacity is growing. The advent of fast charging era also promotes the development of NTC thermistor. In quick-acting charging equipment, in order to prevent equipment damage caused by overcharging or external temperature influence, resulting in explosion and fire, manufacturers generally choose to install high sensitivity NTC thermistor, to play the role of temperature protection and temperature monitoring.
The popularity of quick-acting charging equipment benefits from the unification of USB Type-C connectors. Using universal interfaces can not only reduce the number of proprietary interfaces and special adapters, but also reduce the generation of electronic waste when the equipment is out of use, which is saving energy and protecting the environment. Smart phones are the first market where quick-acting charging technology found a breakthrough, and the convenience brought by quick-acting charging has been deeply rooted in people's hearts. Starting from mobile phones, manufacturers of quick-acting charging equipment have gradually covered seven major markets, including tablet PCs, laptops, displays, new energy automobiles, electric tools, and IoT (Internet of Things) devices. Now, let EXSENSE Electronics to popularize the quick-acting charging development of each market:
First, smartphone
Billions of smartphones are shipped each year, which is contributing to the popularity of quick-acting charging. In the mobile phone era today,the battery life of mobile phone is a problem that almost everyone will face.
From beeper to cellular phone, feature phone, smart phone, from AAA disposable dry battery to recyclable charging polymer cell, from 1W slow charging to 120W quick-acting charge, we have witnessed the rapid change of charging technology, and witnessed the significant improvement of charging power, which also shows that mobile terminal and quick-acting charging market is inseparable.
Second, tablet PC, laptop
Tablet PC and laptop are the main contributors to the popularization of high-power quick-acting charging, which has brought practical use demand. In particular, 65W and 90W Power have promoted the popularity of multi-port quick-acting charging and PD (Power Delivery) portable charger.
Third, new energy automobile
According to market data, the sales volume of new energy automobile in 2020 has exceeded 3.2 million, and USB Type-C is used as the standard of newly launched electric automobile, which is probably the largest "portable charger" on the market. Compared with oil-fueled car which quick-acting charger needs to be purchased to achieve quick-acting charging function, new energy automobile put this technology standard, it is really convenient.
Fourth, the electric tool
Electric tool with built-in lithium battery is very popular in daily life. Due to they provide convenience for assembly or disassembly. However, most of the popular products use linear charging, which takes a long time to charge and also affects the use experience. If linear charging can be upgraded to quick-acting switching charge, or add the battery pack that needs a special charger to charge into the buck-boost voltage charging circuit,so that it can be charged quickly, user experience can be improved and the time required for battery charging can be greatly shortened.
Fifth, IoT device
The Internet of everything makes many traditional home appliances a member of smart home equipment. Besides, the equipment that all sorts of close-fitting use also entered intelligent household category. There are so many kinds of IoT devices that cover every aspect of our lives. IoT devices enter the market of quick-acting charging, which starts from interface unification. USB Type-C has become the first choice of new smart home devices, and smart home devices with built-in large-capacity batteries are naturally the best application partner of quick-acting charging.
High sensitivity NTC thermistor produced by EXSENSE Electronics Technology Co., Ltd. has the characteristic that the resistance value decreases with the increase of temperature, and conversely increases, which can play the role of temperature protection in the quick-acting charging equipment and assist it to work better.
