ELECTRONIC DEVICE METHOD FOR CONTROLLING CHARGING CURRENT FOR MULTIPLE BATTERIES BASED ON SENSING RESISTORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18310111 titled 'ELECTRONIC DEVICE METHOD FOR CONTROLLING CHARGING CURRENT FOR MULTIPLE BATTERIES BASED ON SENSING RESISTORS
Simplified Explanation
The patent application describes an electronic device that includes a processor, two batteries, and two sensing integrated circuits (ICs) to monitor the charging currents of the batteries. The processor can adjust the total charging current based on the identified values from the sensing ICs.
- The electronic device has at least one processor, two batteries, and two sensing ICs.
- The first sensing IC measures the total charging current for both batteries through a sensing resistor.
- The second sensing IC measures the charging current for the second battery through another sensing resistor.
- The processor can set the total charging current to different values.
- The processor adjusts the total charging current based on the identified charging current values.
- If the first charging current value exceeds a reference value or the second charging current value exceeds another reference value, the processor sets the total charging current to a lower value.
Potential Applications:
- Mobile phones, tablets, and other portable electronic devices that use multiple batteries.
- Electric vehicles or hybrid vehicles with multiple battery packs.
Problems Solved:
- Efficiently monitor and control the charging currents of multiple batteries.
- Prevent overcharging or overheating of the batteries.
- Optimize the charging process for longer battery life and improved safety.
Benefits:
- Improved battery management and protection.
- Enhanced charging efficiency and performance.
- Extended battery lifespan.
- Increased safety during the charging process.
Original Abstract Submitted
An electronic device includes: at least one processor, a first battery, a second battery, a first sensing integrated circuit (IC) configured to identify a measurement value of a total charging current for charging the first battery and the second battery through a first sensing resistor connected to the first battery and the second battery, and a second sensing IC configured to identify a second charging current value for the second battery through a second sensing resistor connected to the second battery. The at least one processor may be configured to set the total charging current to a first value. The at least one processor may be configured to set the total charging current to a second value, the second value being less than the first value, based on identifying a first charging current value greater than a first reference value or the second charging current value greater than a second reference value.
