초록

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...
