Battery monitoring and control system and method of use including redundant secondary communication interface
First Claim
1. A battery monitoring and control system comprising:
- at least one battery cell operatively connected with at least one electronic device;
at least one battery monitor module, associated with each of the at least one battery cells, and having a primary communication interface and a redundant secondary communication interface;
a system controller in operative and in signal communication with each battery monitor module configured to monitor and gather data from the at least one battery chip, and to execute instructions to control charge balancing of the at least one battery cell;
primary and secondary communication links configured to independently electrically couple the at least one battery monitoring module to the system controller.

Abstract
A battery monitoring and control system and method of monitoring and controlling provides a redundant and independent symmetric secondary serial bus in addition to a primary serial bus within a battery monitoring and control system that includes a plurality of battery monitoring modules and associated IC battery monitor chips in serial communication with a system controller. Additionally, no two serial communication pins from an interface in operative communication with an associated one of a primary or a secondary serial bus are directly adjacent thereby allowing for continuous battery operation when a single pin in a series of battery monitoring modules becomes non operational failed. Additionally, the battery system remains operational when an open or short circuit occurs in only one of either the primary or secondary serial bus.

17. A battery monitoring method for monitoring and controlling a battery monitoring system including an electronic device and battery cells that operate to power the electronic device in operative electrical communication with a system controller and a plurality of associated battery monitoring modules comprising:
-
performing a self-test of the system to determine system functionality; determining functionality of a primary serial communication link; determining functionality of a redundant secondary serial communication link; selecting a communication link from the primary or the secondary serial communication link to communicate between one or more battery monitor modules and a system controller; providing notification to a user if system functionality is reduced; and implementing a limited operation strategy (LOS) if the system functionality is reduced. - View Dependent Claims (18, 19, 20)
