Microsoft has always advertised Surface devices as those with an amazing battery. While Surface devices do have great battery life, they take a lot of time to charge which can be annoying for people who are always on the move.
However, it looks like Microsoft is finally working to solve the problem. According to a patent published by the United States Patent and Trademark Office titled, “Smart batteries for ultrafast charging”, Microsoft might be working on smart batteries for fast charging. The patent was filed by Microsoft back in February 2017 and was published on 23rd August 2018. It explains the working of the smart battery which will have the ability to charge faster than its existing counterparts.
Methods and devices are described for charging a smart battery in a computing device. The methods and devices may include determining, by a battery management controller, a charging configuration for managing one or more battery modules of the smart battery and transmitting a charging configuration signal to one or more battery modules of the smart battery.
The methods and devices may include receiving, by at least one of a plurality of charging coils, power from a wireless signal based on the wireless signal coupling energy to at least one of the plurality of charging coils at a frequency as the at least one of the plurality of charging coils and charging at least one battery module connected to a respective one of the plurality of battery control boards in response to a respective one of the plurality of charging coils receiving the power from the wireless signal.
Since there is no other evidence of the technology apart from the patent, it’s safe to say that Microsoft still needs some time to make it happen. Unfortunately, this means that we will have to wait for at least a couple of years before Microsoft starts implementing the technology into the Surface devices.
