BALANCE CHARGING DETECTOR
First Claim
1. A balance charging detector comprising:
- a controller operable for monitoring a status of a battery, for accessing a plurality of battery parameters for said battery that correspond to said status, and for generating a group of balance charging parameters based on said battery parameters; and
a comparing module coupled to said controller, and operable for setting a balance charging flag based on a comparison of said group of balance charging parameters and a set of thresholds,wherein a balance charging signal is generated if said balance charging flag is set to indicate presence of a condition to perform a balance charging of said battery.

Abstract
A balance charging detector is configured to detect a balance charging condition for a battery. The balance charging detector includes a controller and a comparing module. The controller is configured to monitor a status of the battery, access battery parameters for the battery that correspond to the status, and generate a group of balance charging parameters based on the battery parameters. The comparing module is configured to set a balance charging flag based on a comparison of the group of balance charging parameters and a set of thresholds. A balance charging signal can be generated if the balance charging flag is set to indicate presence of a condition to perform a balance charging of the battery.

20. A method for detecting a balance charging condition for a battery, said method comprising:
-
accessing, through a controller, a plurality of battery parameters for said battery that correspond to a status of said battery, and generating a group of balance charging parameters based on said battery parameters; setting, through a comparing module, a plurality of balance charging flags based on a comparison of said groups of balance charging parameters and a plurality of sets of thresholds, wherein the number of said sets of thresholds is the same as the number of said groups of balance charging parameters; and monitoring said balance charging flags and outputting a balance charging signal to indicate presence of said balance charging condition if a balance charging flag of said balance charging flags is set. - View Dependent Claims (21, 22)
