Android fast charge technology

Electronics weiqhd Times

Although the fast charging technology seems to many sects, but in general there are only two kinds: high voltage and large current. In addition to DASH and VOOC are large current fast charge technology, and the rest of the basic is a large voltage. Whether large voltage or large current, and ultimately through the increase in power to enhance the speed of charging fast charge. Next we have to look at the 6 kinds of Android camp fast charge technology, popular science about the field of mobile phone battery life.
Charge 1.0/2.0/3.0 Qualcomm:Quick

Qualcomm Quick Charge 3 (QC 3) fast charge technology imperceptibly is already Qualcomm third generation fast charging technology, a few years ago when the fast charging technology is not burgeons, QC martial attention is still pretty high. A few years ago QC 1 and QC 2 are still more popular with the mobile phone manufacturers and consumers. In particular, QC 2 technology, and now a lot of mobile phone manufacturers in the fast charging technology is based on the extension of the QC 2 based on, for example, will be mentioned below Moto turbo charging and vivo twin engine flash charge.
QC 1: maximum support 5V/2A charging power.
QC 2: compatible with 5V/9V/12V/20V four file charge voltage.
QC 3: 200mV increments from 3.6V to a file, provide the flexibility to choose 20V voltage, so that mobile phone manufacturers can adjust the best voltage according to their own needs, to achieve the desired current, charging efficiency while reducing power consumption and fever. Currently on the market the standard QC 3 fast charging head and supports the LG protocol of the mobile phone G5, millet mobile phone 5.
Plus MTK:PumpExpress
A few years ago because of MTK fast charging technology is backward in charging speed field has been Qualcomm rolling, PumpExpress technology began to emerge in recent years, the built-in power management integrated circuit PMIC, allowing the charger according to the initial voltage and current charging required. The pulse current issued by the PMIC command transmitted through the Vbus USB to the charger, and then adjust the output voltage according to this directive, and gradually increased to 5V to achieve maximum charging current.

PumpExpress output power <10W, pumpexpress> 15W. The latest Pump Express 3.0 claims to be able to charge 70% of your smartphone in 20 minutes, while reducing the heat by 50% compared to PumpExpress Plus. Compared to QC 3.0 200mV for a file incremental approach, PumpExpress 3.0 voltage trim amplitude of only 10mV, the theoretical maximum charge current can provide 5A. MediaTek said Pump Express 3.0 fastest in the Helio P20 to achieve.
FCP (Fast Charger Protocol)
In this case,
Last year, Huawei Mate 8 and glory 7, this year's glory V8 and Huawei P9 on the FCP is equipped with Huawei's own fast-charging technology, in June this year, Huawei launched the 10000mAh glory mobile power also supports the technology, up to 9V / 2A (18W) fast charge output power.
USB PD (USB Power Delivery Specification)

In this case,
Many consumers have been misunderstanding that USB Type-C interface and data lines of the smart phone charging speed and data transfer speed will certainly be fast. Lenovo ZUK Z1 and music 1 three models are used USB Type-C data cable, but only the Lenovo ZUK Z1 data transfer speed compared to ordinary micro-USB interface models Has increased, a plus mobile phone 2 and music 1 in this aspects transfer speed upgrade does not. In fact, the real reason for speed is Lenovo ZUK Z1 in the use of USB 3.x protocol.
Then the use of USB Typc-C interface model charging speed is necessarily faster? The same is not necessarily. This is mainly the USB PD protocol at work, if only USB Type-C interface is not compatible with USB PD protocol or QC 3.0 fast charging technology, the charging speed is also not significantly improved. Currently on the market compatible with USB PD protocol and comes with the agreement fast charge of the phone is not much, Le Max 2 is one of the representatives. Unfortunately, there is no use of USB 3.x specification, data transfer rate is not stunning.
In this case,
Back to the USB PD specification up, compatible with the norms of music Max 2 charging speed is very fast, but does not fully reflect the potential of USB PD specification. USB PD specification mobile power, the maximum output power of 72W (13.2V / 5.4A), this is the USB PD specification in the future is quite potential to become the mobile device industry standard reasons.
OPPO: VOOC flash technology
In this case,
As early as the OPPO Find 7 we have experienced the VOOC flash technology, after the N series and R series also began to popularize the technology. Now "charge 5 minutes call 2 hours" Slogan Street has been known to smell, as a symbol of the brand. And the above-mentioned fast charge technology is different, VOOC flash charge technology main high current rather than high voltage, OPPO original fast charge head supports up to 5V / 4A power output, insert does not support VOOC flash mobile phone can generally achieve 5V / 2A Power output.
OPPO Find 7 standard when the first generation of VOOC fast charger and fast-charge head and USB cable can not be separated, and the volume is relatively large. Until the OPPO N3 and OPPO R5 introduced the second generation of fast charge to achieve the volume compression, and made a separable design. Of course, the charging speed increased, security will naturally be pushed to the cusp, OPPO applied for 18 patents, including the Swiss IEC, including a number of authoritative certification. At the same time integrated OPPO exclusive R & D five-fold security technology.
A plus: DASH speed flash charge
In this case,
Similar to the OPPO VOOC flash charge technology, a plus there are DASH speed flash charge technology, the original charger can also be the highest output 5V / 4A power. Coincidentally also has a 5 protection technology, from the charging adapter to the phone side, each wire power will go through five full-end protection technology: adapter overload protection, flash charge condition protection, interface overload protection, battery overload protection, battery Fuse protection. But that sentence, OPPO and a plus flash charge and charge the original line to buy accessories, many of the explosion is actually a consumer to buy a fake as well as non-original parts caused.
QC fast charge technology extension Today, many Android vendors have introduced a lot of unaware of Li's exclusive fast charge terms, to put it bluntly are based on QC and PumpExpress Plus (hereinafter referred to as PEP) extended out. We take a look at QC camp secondary processing fast charge technology.
Moto Turbo Charging Technology
In this case,
Today's Moto has been worse than before, but fast-charging technology or leverage. Moto X Style and Moto X comes with a one-piece fast charge head (similar OPPO Find 7 fast charger can not be separated) of the charging effect we are impressed with, from the fast charging head specifications we can see that its maximum support 5V / 9V / 12V third gear voltage, current into the 2.85A / 2.15A two grades, the maximum output of 25W charging power.
Dual - engine flash charge
In this case,
Many consumers feel that dual-engine flash technology is also very fast, and those who are compatible with QC 2.0 models even slightly better than, in fact, is based on the upgrade from the QC 2.0. According to the official description of this mainly due to its use of dual-charge chips and dual charging circuit, together with the vivo custom flash rechargeable battery, brought twice the normal mobile phone charging speed, unique nine recharging protection system, charging faster and more secure . From vivo X7Plus the original fast charge point of view, the output power of 9V / 2A and 5V / 2A two specifications.
PEP fast charge technology extension PEP fast charge technology representatives have Meizu mCharge 3.0 and Jin Li lightning fast charge.
Meizu mCharge 3.0
In this case,
Although the Meizu PRO 5 and Meizu PRO 6 are equipped with a 24W quick charge, but the Meizu but they are equipped with fast charge technology is divided into mCharge 2.0 and mCharge 3.0. The former is based on MTK PEP, while the latter is MTK PEP 2.0. In addition, two models charge head support technology is also different. It is worth mentioning that, in addition to Meizu PRO 6 USB Type-C interface, compared to Meizu PRO 5 also USB specification upgrade to 3.1 version, similar to the above mentioned Lenovo ZUK Z1 to provide faster data transfer speed.
Jin Li lightning fast charge
In this case,
Coincidentally, JinLi flash fast charge technology and vivo dual-engine flash charge technology is similar, also uses a dual-charge chip design, two sets of charging chip can achieve intelligent regulation of charge current, effectively alleviate the fast charging mobile phone heating phenomenon. Jin M6 and Jin M6 Plus, for example, the former highest support 9V / 2A fast charge standard, which is 12V / 2A.
Fast charge technology compatibility issues
Meizu PRO 5 in the publicity page we can see that in addition to support mCharge 2.0 (based on MTK PEP), also compatible with PD protocol charger, in other words a phone can support more than one fast charge technology. This is even more common in mobile power supplies and fast-charge products. This phenomenon is very common, happy Max 2 compatible QC 3.0 and PD dual fast charging protocol, Huawei Mate 8 supports both QC 2.0 and its own FCP two fast charge technology. ''
Summary On the fast charging technology Many consumers have a misunderstanding, always feel that the Samsung Exynos SoC equipped with Samsung fast charge technology, MediaTek SoC equipped with MTK fast charge technology, Qualcomm Xiao Long SoC equipped with QC fast charge technology. In fact, not necessarily fast-charge technology chips and circuits can also be purchased separately, the most classic example is the Meizu PRO 5 although the Exynos platform, but integrated MTK PEP fast charge program, rather than the Samsung AFC standard. Similarly, vivo using MTK platform models still support the QC 2.0 standard based on the twin-engine flash technology.
On the other hand, Samsung flagship equipped with its own AFC fast charge standard, while compatible with QC 2.0. The Samsung C5 and Samsung C7 does not support QC fast charge technology, you must use Samsung's own fast-charging head before they can quickly charge. Samsung Galaxy Note7 also supports QC, PD and AFC three major standards.
Based on this principle, we can easily understand the above-mentioned dual-protocol fast charge program, mobile phone manufacturers as long as willing to give money, you can get from different fast-charge solution suppliers, not to mention two fast charge integrated program, On is also possible.
