  • Battery monitor which indicates remaining capacity by continuously monitoring instantaneous power consumption relative to expected hyperbolic discharge rates
    Patent number: 5394089
    Abstract: A battery monitoring system (10) supplies the user of a battery power system with information indicating the capacity remaining in the battery (9) during discharge. During discharge the system (10) monitors various parameters and calculates on a rapid sampling basis derived parameters from algorithms stored in memory in tabulated form. The recharging efficiency is also evaluated, stored and updated on each charge/discharge cycle so that ageing of the battery (9) is monitored.
