Formula efficiency exceeds 17%～about 30%.
As shown in Figure 6, lithium battery protection circuit in the present embodiment, can control following five kinds of states of battery: generally state,
Overcharge condition, over-discharge state, resting state, overcurrent condition.
1, usual state
Main storage battery and secondary battery voltage detect voltage V in overdischargeDLnVoltage V is detected with overchargeCUnBetween, ratio is put
Electricity electric current current value low (VINI terminal voltage than discharge over-current detect voltage VIOV1、VIOV2Low, and VMP terminal voltage ratio
VIOV3High) in the case of, charging FET and electric discharge FET becomes ON.
2, overcharge condition
The voltage ratio overcharge detection voltage V of wherein certain battery of main storage battery and secondary batteryCUnHeight, this state
It is maintained at tCUIn the case of above, COP terminal becomes high impedance.COP terminal is EB by outer meeting resistance pull-up+Reason, fill
Electricity FET becomes OFF, and stops charging.This state is referred to as overcharge condition, and overcharge condition is meeting following two condition
In one be i.e. released from: A, whole cell voltages overcharge release voltage VCLnTime following；B, whole cell voltages exist
Overcharge detection voltage VCUnHereinafter, and VMP terminal voltage is at 39/40XVDDTime following, (load is connected, is used by charging
The body diode of FET starts electric discharge).
3, over-discharge state
The voltage ratio overdischarge detection voltage V of wherein certain battery of main storage battery and secondary batteryDLnLow, this state
It is maintained at tDLIn the case of above, the voltage of DOP terminal becomes VDDLevel, electric discharge FET becomes OFF, and stops charging, this
The state of kind is referred to as over-discharge state, and after becoming over-discharge state, chip S-8254 transfer is resting state.
4, resting state
Becoming over-discharge state, stop electric discharge, the RVMS resistance VMP terminal within IC is pulled down to VSS, VMP terminal
Voltage becomes VDDWhen less than/2, chip S-8254 enters resting state.The most electricity of chip S-8254 in the dormant state
Road quits work, and consumes electric current and becomes IPDNBelow.The state of each lead-out terminal becomes following state: COP:Hi-Z；DOP:
VDD.It is released from when meeting following condition in the dormant state: VMP terminal voltage becomes VDD(it is connected to charger) when less than/2；
Over-discharge state is released from when meeting following condition: the voltage of all batteries becomes VDLnAbove, and VDD terminal voltage
Become VDD(it is connected to charger) when more than/2.
5, overcurrent condition
The overcurrent detection level (V of standby corresponding 3 types of chip S-8254IOV1、VIOV2And VIOV3) and respective level
Overcurrent detection time delay (tIOV1、tIOV2And tIOV3).Discharge current (V bigger than certain valueSSAnd VINIVoltage difference compare VIOV1
In the case of greatly), this state is maintained at tIOV1Time above, chip S-8254 enters overcurrent condition.At overcurrent condition,
The voltage of DOP terminal becomes VDDLevel, electric discharge FET becomes OFF, and stops electric discharge.It addition, COP terminal becomes high impedance, by
Current potential in EB+ terminal is pulled up, and causes charging FET to become OFF.VMP terminal is pulled to V by internal resistance RVMDDD。
Level 2 (V is detected for overcurrentIOV2) and overcurrent detection (t time delayIOV2) work with for VIOV1And tIOV1's
Work is identical.
At overcurrent condition, it is pulled to V by the RVMD resistance VMP terminal within ICDD, overcurrent condition is under meeting
It is released from when stating condition: being connected by charger or load open (more than 30M Ω), VMP terminal voltage is at VIOV3Time above.
This circuit also can select following two about the charging of battery after self discharging (0V battery), chip S-8254
A function side therein: A, permission are to the charging (can charge to 0V battery) of 0V battery, and charger voltage compares V0CHAHigh feelings
Under condition, 0V battery is electrically charged；B, forbidding the charging (cannot charge) to 0V battery to 0V battery, cell voltage is at V0INHBelow
In the case of, it is not charged.
As it is shown in fig. 7, in the present embodiment, battery intelligent distributor circuit includes main storage battery charge management circuit, secondary electric power storage
Pond charge management circuit, main storage battery power-supplying circuit and secondary battery power-supplying circuit, as shown in Figure 8, dual system is micro-
Processor and the connection circuit diagram of LED drive module.The present invention is under original system model, by the solar energy of same homalographic
Cell panel is divided into the solar panel of small one and large one two groups of independences.Such as: solar panel is divided according to Radix Notoginseng, originally
The power of solar panel is 64W, is divided into now 45W and 19W, corresponding accumulator to be also equipped with two pieces, and capacity is according to Radix Notoginseng
Point, originally capacity is 12V, 40AH, is divided into now 12V, 28AH and 12V, two pieces of independent accumulator of 12AH, after fractionation, both
Do not increase cost and the most do not increase volume, then carry out management of charging and discharging, Concrete workflow by the pcb board that Ben Shentong provides
Journey figure is as shown in Figure 9.
Operationally, pay the utmost attention to whether secondary battery electricity reaches the capacity of 80%, because secondary battery capacity is only
12AH, the capacity of 80% is easily achieved, and the capacity of 80% can just discharge a whole night simultaneously.In conjunction with electric discharge planned in advance
Curve (discharge curve refers here to the different time periods different brightness, it is ensured that when before midnight, personnel activity was frequent
Highlighted state) rationally discharge.When secondary battery discharges, main storage battery is in resting state, i.e. secondary battery works a whole night,
Main storage battery can be charged continuous two daytimes.When after secondary battery work a whole night, daytime main storage battery and secondary battery
Simultaneously in charging, say, that in the case of assuming that secondary battery was not full of evening on the same day, main storage battery works a whole night, secondary
Accumulator can fill two daytimes.Being typically based on the generated energy of solar panel, under rainy weather, secondary battery needs 3
It can be full of, and storing electricity is discharged by an evening, and namely secondary battery is charged continuous 3 daytimes, and 2 evenings treat
Machine, works 1 evening, main storage battery be then need 7 days fully charged, can be with continuous discharge 5 days, for main storage battery with secondary store
The such multiple authentication that circulates through of battery confirms as great application breakthrough, it is achieved 365 days bright lights, anti-overcast and rainy days carries significantly
Rise, there is no concern that discharged or defective battery runs when experiencing winter or rainy season, reduce accumulator and deeply fill the number of times deeply put, so electric power storage
Pond service life is original several times, and is effectively improved flying power and the brightness of illumination of accumulator.
Although specifically showing and describe the present invention in conjunction with preferred embodiment, but those skilled in the art should be bright
In vain, in the spirit and scope of the present invention limited without departing from appended claims, in the form and details can be right
The present invention makes a variety of changes, and is protection scope of the present invention.
