Patent granted for circuit control method for battery charging
A recently granted patent (Publication Number: US11973364B2) discloses a circuit control method for managing the charging and discharging of a battery in an apparatus. The method involves acquiring a wake-up signal, determining the power source terminal voltage of the charging circuit, and issuing instructions based on various thresholds related to the battery's state of charge, fault alarms, and temperature. The instructions control switch units in the charging circuit to turn it on or off, ensuring efficient battery management.
Furthermore, the patent includes claims for a battery controller, a battery management system, a battery, an electrical apparatus, and a vehicle equipped with a lithium battery, a generator, and a vehicle wake-up switch. The battery management system, when integrated into the battery or the electrical apparatus, facilitates the implementation of the circuit control method described in the patent. The system enables the monitoring of power source terminal voltage, battery state of charge, and other parameters to optimize the charging and discharging processes, ensuring the efficient operation of the battery within the apparatus or vehicle.
