Canon Patents Battery Indicator That Shows The Lifespan Of Connected Packs

Canon has filed a patent for a system that expands a camera’s battery indicator to also display the remaining life of a connected USB-C battery power supply.

According to patent document, this update will show both the charge status of the internal battery (normal) as well as the battery percentage of the connected external power supply.

Patent documents, noted by Canon News, has been registered in Japan in January and released on August 5.

According to the present invention cellular device, a battery device, the full charge capacity of the battery of an electronic device the remaining amount of the battery connected to the battery device of the battery device It has a display means for displaying information indicating the result of a calculation based on.

According to the present invention, it is possible to notify the full charge capacity of the battery of the electronic device, a user easy to understand the relationship between the remaining amount of the battery and the device connected to the battery to the electronic device.

While Canon’s language here is a bit convoluted and isn’t the best description of what to expect, in short, it will allow the camera to recognize how much power is available on both its battery. internal and on what remains in the connected power banks. . This kind of information could be very useful for timelapses and astrophotographers who have to let their systems run for hours. It would also be particularly useful for filmmakers who want better visibility into how long they will be able to operate their cameras.

Based on the schematics and full documentation, it looks like Canon intends to allow reading up to four different batteries. It is not clear if this means four separate batteries, or if the external USB batteries will be separated based on the equivalent charge of the internal battery and “separated” for a better understanding of the additional life of the camera. .

The documentation implies that as the main battery is powered by the USB battery pack (s), the new power indicators will provide an accurate description of the amount of combined power remaining in the system.
