Embodiment Construction
[0036] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0037] A lithium battery power monitoring system includes a state monitoring unit, a power recording unit, an impedance tracking unit, a computing unit and a lithium battery.
[0038] Among them, the state monitoring unit monitors the current output voltage, output current and ambient temperature of the lithium battery, and the power recording unit records the input power when the lithium battery is charged and the output power when the lithium battery is discharged; the impedance tracking unit calculates the lithium battery after each charging of the lithium battery. Internal impedance, the calculation unit calculates the remaining power of the lithium battery and the remaining working time of the lithium battery according to the input data;
[0039] When the lithium battery is being charged, the state detection unit monitors the inpu...
