Abstract

A stand-alone battery monitoring system coupled to a battery product having a positive pole and a negative pole, a housing and an electronics package contained within the housing. A sensor is coupled to and communicates with the battery product and the controller. Multiple code segments form software on the controller, the software includes a code segment acquiring battery product data for voltage and internal temperature from the sensor, a segment filters the acquired battery product data into modified battery product data and processing the modified battery product data against stored parameters, a segment stores battery product data in the portion of memory and retains the battery product data to provide historical battery product data. A code segment compares the stored data against threshold levels and an indicator sends an alert if the code segment comparing the stored battery product data against threshold levels determines that data is beyond those levels.
