Microsoft joined hands with Tesla to develop software to extend battery life
.
To extend battery life, research teams from Microsoft, Tesla and others have come up with a solution that mixes different types of batteries in a device, with the system itself managing
the battery.
Tests conducted by the researchers have shown that hybrid-configuration batteries can extend the battery life of wearable devices by about 1 hour
.
The improvements brought about by Software Defined Batteries are very personalized, but in some parts they are limited by the battery
that the manufacturer configures in the device.
The researchers said that batteries with different chemical compositions have different charging and discharging characteristics
.
And not every battery chemistry is ideally matched: high-capacity batteries can take hours to charge, and fast-charging batteries may not have large enough capacity
.
Usually the devices we use have built-in sensors and controllers, and the researchers say they can consider applying them to batteries
.
The researchers said, "For small devices, half of the battery volume can be used for fast-charging batteries and the other half for high-energy density batteries
.
" This allows the device to charge up to 50% quickly and consume relatively less
power.
”
The paper also points out that system and battery communication require a new combination
.
At present, the communication between the system and the battery is single: the dedicated charge controller charges the battery according to the ration, and the system only regularly queries the battery status, so the solution proposed by the researchers is that Windows or other operating systems communicate with the charger and control the charger to optimize the overall battery life
of the device.
For wearables, Microsoft integrates a less efficient, bendable battery in the strap; Integrate a highly efficient lithium-ion battery
behind the display.
When the user sits at the table, the wearable device will enter a low-energy mode, using the former for power; When users are ready to run, heart rate and distance need to be monitored, and wearables are powered
by efficient lithium-ion batteries.
Because software-defined batteries do not increase controller costs, they can be used in devices
such as drones, smart glasses, and electric vehicles.
The researchers' next step will be to test SDB using voice assistants such as Cortana and Google Now, as well as investigate the possibility of
controlling SDB.
