Patent ID: 8013611

Claim:
A method of operating a vehicle battery monitoring system in communication with a vehicle battery product, the method comprising: waking the battery monitoring system from a dormant state; transmitting and receiving information regarding the vehicle battery product and updating said information based on initial data input by a user; sensing at least a battery product voltage and a battery product temperature; acquiring battery product data from the battery product voltage and the battery product temperature; filtering the acquired battery product data into modified battery product data including passing the modified battery product data through a filter code segment and a predictive code segment acting on a predictive, parametric database of values and processing the modified battery product data against stored parameters through a lookup function on a variable event filter table resulting in an output that represents the state of charge or state of health of the battery; storing the acquired, filtered, modified and compared battery product data in the portion of memory and retaining whole or in part the acquired, filtered, modified and compared battery product data to provide historical battery product data over the course of the life of the battery product; comparing the stored battery product data against threshold levels; analyzing the stored battery product data when threshold levels are met; and determining a state of the battery based on the analyzing step and reporting same.
