Quick Charge 3.0 ChargerImprove The Charging Efficiency

Estar Industrial Group Co.,Ltd | Updated: Aug 17, 2017

Over the past couple of years, the word "fast charge technology" has quickly entered the eyes of people and is considered one of the most practical features of smartphones. In fact, the current mainstream smart phone used by the fast charging technology, more from the high-pass chip native support, recently released the latest generation of fast charging technology Quick Charge 3.0, we come to explore what exactly is what we expect the place The

Fast charging is not a fresh concept, as the name suggests, is to make your smartphone charge faster than ever. The easiest way to get the device to be quickly charged is also the most common way to increase the charge current to maximize charge efficiency. The latest fast charge technology, and now also supports the battery to charge higher voltage, the power line to achieve higher power transmission.

However, both smartphones and chargers, they must normally be compatible with the same charge voltage and current, or performing fast charging may encounter several situations

The first case is that if your phone supports a 9V / 2V charge, but your charger current is only 1A, then the entire charging process will become relatively long; and the other is that your charger Current is 2A, but your phone only supports 0.7A current charge, the same will lead to slow charge; there is a situation you are using high-current charger for fast charging equipment is compatible, but because of non-certified products Of the reasons, charging efficiency is also difficult to be guaranteed.

To tell the truth, the early advent of fast charging technology, most of them are similar to the technology, that is, optimize the initial charging process of transmission power, so that the user power shortage, to a very short time to the appropriate amount of power, and then unplug the line use.

The first is to optimize the power output, the specific thing is to let the portable device has the ability to select the required power level to achieve the best power transfer at any time, and maximize efficiency. For example, Quick Charge 3.0 can achieve up to 38% more efficiency than QuickCharge 2.0.

In addition, during the battery charging cycle, INOV has the function of dynamically adjusting the charging voltage. When the battery is charged, it absorbs the current slowly and less, which is why the last 20% of the charging time will be 80% longer than the previous reason. Qualcomm pointed out that as long as the voltage in line with the provisions of the range, with the help of INOV technology, the phone can be knocked to the benefits of the voltage and the expected charge current.

The dynamic adjustment of the voltage of the INOV technology naturally brings the flexibility of the charging options to enhance. Before Quick Charge 2.0 supports four modes to charge at different power levels, respectively, 5V / 2A, 9V / 2A, 12V / 1.67A and 20V fourth gear charge voltage. The new Quick Charge 3.0 is available in 200mV increments, providing a flexible choice from 3.6V to 20V.

In general, Quick Charge 3.0 technology is nothing more than a significant reduction in the amount of electricity during the charge was wasted, "charging efficiency" has become the key to the technology, 38% of the upgrade gratifying. In contrast, before the charging process a lot of extra power can not be used to charge the battery, loss and lead to heat, the phone machine temperature and therefore increased to reduce the battery life. Qualcomm through the charge of the sales of more control, to a certain extent and minimize the power loss, to maximize the efficiency of charging and improve the performance of heat.
