Abstract
The utility model discloses a status indicating management system for a lithium iron phosphate battery. The system comprises a battery charging and discharging detection unit, a battery real-time capacity correction unit, a battery residual charge calculation unit and a battery residual charge display unit. According to the system, the actual capacity of the lithium iron phosphate battery is calculated by subtracting accumulated discharge power after discharge from accumulated charge power when the battery is fully charged, and the actual capacity of the battery is a dynamic value which changes with the time of use; and by calculating the percentage of the residual charge to the actual capacity, the actual battery residual charge is calculated and displayed, such that the residual charge of the lithium iron phosphate battery is truly reflected.
