After the release of any phone, people generally try to compare the new with the old version based on its display, memory chips, and performance. The latest in this category is the invention of the fast charger. This technology allows the user to charge their phones within a short time quickly. Charging includes a significant amount of technological advancements in it, whether keeping in mind the physical or chemical aspects of it. But the question arises as to how the fast charger works. The battery, which is present in all the smartphones, similarly transmit power. In chemistry, cells consist of both positive as well as negative electrodes.
The acceleration of reaction by the electrolyte converts the compound into a whole new substance. Over time, ions formed in the electrons, drive the electrons to the negative electrode, thereby charging the phone. Generally, the above-mentioned reaction takes place only once in non-rechargeable batteries. But, the responses are reversed in rechargeable lithium-ion batteries. In this situation, the electricity produced by the chemical reaction recharges the battery, and the chemical reaction absorbs the power.
In-house Technologies
In most smartphones, the companies use their in-house technologies when it comes to charging the device. However, they do keep in mind a few of the genuinely proprietary standards. Some deliver quick charge while some have power delivery, brands rename the technology by bringing about certain changes in specific mechanisms. Like Samsung has its Adaptive Charging while Motorola has its Turbo Charging options. Mostly the same, they vary in particular technology used.
While it is possible to support several standards, companies ensure to at least have some compatibility even with different fast charging methods. This is the same reason why different brand chargers have different levels and time of charging. Also, for the exact motive, brands prefer different charger adaptors and cables. Fast charging technologies continuously exploit the current phase. It pumps in as much charge as possible before the battery reaches its peak voltage. This is why quick charging options are best used when the battery level is less than 50% and does not really have any effect if the device is already charged up to 80%.
After knowing how the batteries to charge, let us understand how the fast charger works. The chip controls the flow of electricity in and out of the cell, and also the amount of power in the device. The USB cables help in charging any phone’s battery. There are four types of USB specification – USB 1.0, 2.0, 3.0, and 3.1. The USB 1.0 and 2.0 plug ensures 5V/0.5A (2.5W).
