A new smart chip about the size of a fingernail is set to hit markets in 2016 that can charge a smartphone fully in less than 10 minutes as well as offers safety improvements.
The new piece of wonder has been developed by Professor Rachid Yazami of Singapore’s Nanyang Technological University (NUS) and could drastically change the way we charge our devices.
The pioneer in battery research, Yazami who won the 2014 Draper Prize (known as the Nobel Prize for engineering) for being one of the three founders of lithium-ion battery in the 1980s by making them safe to recharge that now powers many electrical devices today, says his chip could cut recharging times down to ten minutes and extends battery life as well as lowers the risk of battery fires.
Yazami’s new invention, which took five years to develop, is small enough to be embedded in most of the today’s smartphone batteries. and it’s life.
How It Works
It contains a special algorithm that monitors the battery’s current health and charge level. This allows the charger to send the optimum amount of current to the device at all times, without any of the risks currently involved.
At present, lithium-ion batteries charge by having electrical energy slowly drip-fed into them in tiny amounts in order to prevent them from overheating, so the process makes it take longer for them to charge.
But Yazami’s latest breakthrough claims to allow batteries to be charged at full speed by measuring the voltage and temperature of the batteries and alter the amount of current reaching the battery accordingly. Lithium-ion batteries will benefit from it as the chip would be able to tell the charger the exact amount of energy left.
“We have patented an adaptive charging protocol (ACP), which is different from the current constant current-constant voltage protocol (CCCV),”
“ACP takes into account parameters such as the battery chemistry, the state of health and the charging time. Conventional fast-charging comes with a cost, such as a shorter life of the battery. Our ACP minimizes capacity losses after each charge/discharge cycle, therefore, extends the battery life.”
The Future System of Charging Arrives Next Year
The chip is expected to be available for chipmakers and battery manufacturers to license by the end of 2016.
Yazami has already been in talks with companies like Sony, Sanyo, and Samsung.
Given its size, the applications of this chip extends way beyond smartphones. The inventor hopes that it can be used on electric cars as well, and is also keen to begin talks with Tesla about embedding the technology in its electrical cars to explore its potential for the leading electric car brand.
Improving the battery life of smartphones is one of the main requests from consumers in recent years as smartphones keep them waiting for hours to charge. While the world has yet to see a battery that can power a smartphone for an entire day, we have to wait one more year to see how the technology revolutionizes the way of battery charging.
