ENERGY BASED TASK SHIFTING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17819769 titled 'ENERGY BASED TASK SHIFTING
Simplified Explanation
The patent application describes an electronic device with a power system that can optimize battery charging based on the expected disconnection time of an external power source.
- The processor in the electronic device detects connection of an external power source and estimates the disconnection time.
- It analyzes power grid data to identify desired and undesired battery charging intervals before the estimated disconnection time.
- The power system charges the battery during desired intervals and inhibits charging during undesired intervals by adjusting the charging rate or preventing charging altogether.
Potential Applications
- Smartphones
- Laptops
- Tablets
- Wearable devices
Problems Solved
- Inefficient battery charging
- Overcharging of batteries
- Short battery life
Benefits
- Prolonged battery life
- Efficient use of external power sources
- Reduced energy consumption
Original Abstract Submitted
An electronic device can include a power system including a battery and a processor programmed to detect connection of an external power source to the electronic device, determine an estimated disconnection time at which the external power source is expected to be disconnected from the electronic device, analyze power grid data corresponding to the external power source to identify one or more desired battery charging intervals and one or more undesired battery charging intervals prior to the estimated disconnection time, and operate the power system to charge the battery from the external power source during the identified one or more desired battery charging intervals and inhibit battery charging during the one or more undesired battery charging intervals. The processor can be programmed to inhibit battery charging by reducing the rate at which the battery charges or by preventing battery charging.
