Battery protection system for portable devices
A recently granted patent (Publication Number: US11955823B2) discloses a portable device with a unique battery protection system. The device includes a load module with a discharge switch and a first detection circuit, along with a charge module featuring a charge switch and a second detection circuit. These components are controlled by a battery pack, which includes a protection terminal and protection circuitry that sets a protection signal to different states based on the battery's status. The protection signal dictates the operation of the charge and discharge switches, ensuring optimal battery management. The system offers four states for the protection signal, each triggering specific actions to safeguard the battery's health and performance.
Furthermore, the patent details a method for generating and detecting the protection signal within the battery pack. By utilizing detection circuits in the load and charge modules, the system can effectively control the flow of charging and discharging currents through the switches. The protection circuitry sets the protection signal to different states based on the battery's condition, such as over-voltage or under-voltage scenarios. This dynamic control mechanism ensures that the battery is efficiently charged, discharged, and protected from potential damage. Overall, the patented technology offers a comprehensive solution for managing battery power in portable devices, enhancing safety and efficiency in their operation.
