  • Method and device for monitoring charge and discharge currents of a battery
    Patent number: 11075525
    Abstract: The present invention provides a method and a device for monitoring charge and discharge currents of a battery. The method for monitoring charge and discharge currents of a battery includes the steps of: acquiring charge and discharge currents and charge and discharge states; acquiring an alarm activation threshold, a continuous calibration time for alarm activation, an alarm clearance threshold; and a continuous calibration time for alarm clearance corresponding to the charge and discharge states; activating an alarm if the charge and discharge currents are greater than or equal to the alarm activation threshold and the time of duration exceeds the continuous calibration time for alarm activation, and clearing the alarm if the charge and discharge currents are less than the alarm clearance threshold and the time of duration exceeds the continuous calibration time for alarm clearance.
