ABSTRACT:
In an exemplary embodiment, a battery monitoring system includes sensors for monitoring battery parameters and a memory for storing data based thereon; for example, data may be stored representative of available battery capacity as measured during a deep discharge cycle, and by monitoring battery current thereafter during operation, a relatively accurate measure of remaining battery capacity becomes available. The battery monitoring system may include programmed processor circuitry and may be secured to the battery so as to receive operating power therefrom during storage and handling; thus, the performance of a given battery in actual use can be accurately judged since the battery system can itself maintain a count of accumulated hours of use and other relevant parameters.
