A complete energy management system for lead-acid batteries. The system is designed for deep discharge batteries in traction vehicle type applications such as electric wheelchairs, electric vehicles, golf carts, or industrial equipment, where more efficient use of lead-acid batteries during both the charging and discharging cycle is needed. This system utilizes current measurements, open circuit voltage measurements during the recovery from charging or discharging, and an adaptation calculation to account for variations in physical battery characteristic...
[ What is claimed is:] [16.] A process of battery energy management utilizing a plurality of methods for monitoring the state of charge of a battery, comprising the steps of:a. obtaining a coulometric summation during battery operation by continually measuring said battery's current flow and the duration of discharge;b. accessing, for a predetermined time period, the open circuit voltage following discharge,c. storing said coulometric summation and said open circuit voltage reading in a data processor,d. calculating the current state of charge of said ba...
