In one kind be released from：A, whole cell voltages release voltage V in overchargeCLnWhen following；B, whole cell voltages exist
Overcharge detection voltage VCUnHereinafter, and VMP terminal voltages are in 39/40XVDDWhen following, (load is connected, and is used by charging
The body diode of FET starts electric discharge).
3rd, over-discharge state
Voltage ratio overdischarge detection voltage V of wherein certain battery of main storage battery and secondary batteryDLnIt is low, this state
It is maintained at tDLIn the case of above, the voltage of DOP terminals is changed into VDDLevel, to discharge and be changed into OFF with FET, and stop charging, this
The state of kind is referred to as over-discharge state, and after being changed into over-discharge state, chip S-8254 transfers are resting state.
4th, resting state
It is changed into over-discharge state, stops electric discharge, as the RVMS resistance VMP terminals inside IC are pulled down to VSS, VMP terminals
Voltage is changed into 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 is changed into IPDNBelow.The state of each lead-out terminal is changed into following state：COP:Hi-Z；DOP:
VDD.It is released from when meeting following condition in the dormant state：VMP terminal voltages are changed into VDDCharger is connected to () when less than/2；
Over-discharge state is released from when following conditions are met：The voltage of all batteries is changed into VDLnMore than, and VDD terminal voltage
It is changed into VDDCharger is connected to () when more than/2.
5th, overcurrent condition
The overcurrent detection level (V of standby 3 types of correspondence 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 tIOV1During the above, chip S-8254 enters overcurrent condition.In overcurrent condition,
The voltage of DOP terminals is changed into VDDLevel, to discharge and be changed into OFF with FET, and stop electric discharge.In addition, COP terminals are changed into high impedance, by

In overcurrent condition, V is pulled to by the RVMD resistance VMP terminals inside ICDD, overcurrent condition is under satisfaction
It is released from when stating condition：Connected by charger or loaded open (more than 30M Ω), VMP terminal voltages are in VIOV3During the above.
This circuit be able to also can select following two about the charging of battery after self discharging (0V batteries), chip S-8254
A function side therein：A, the charging (can charge to 0V batteries) for allowing to 0V batteries, charger voltage compares V0CHAHigh feelings
Under condition, 0V batteries are electrically charged；B, the charging (cannot charge to 0V batteries) for forbidding to 0V batteries, cell voltage is in V0INHBelow
In the case of, it is not charged.
As 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-
The connection circuit diagram of processor and LED drive module.This utility model is under original system model, by same homalographic too
Positive energy cell panel is divided into the solar panel of small one and large one two groups of independences.For example：By solar panel according to Radix Notoginseng point,
Originally the power of solar panel be 64W, be divided into now 45W and 19W, corresponding accumulator is also equipped with two pieces, capacity according to
Radix Notoginseng point, originally capacity are 12V, 40AH, are divided into now 12V, 28AH and 12V, two pieces of independent accumulator of 12AH, split it
Afterwards, cost had not both been increased and had not increased volume, the pcb board for then being provided by Ben Shentong had carried out management of charging and discharging, specifically
Workflow diagram is as shown in Figure 9.
Operationally, the capacity whether secondary battery electricity reaches 80% is paid the utmost attention to, because secondary battery capacity only has
12AH, 80% capacity are easily achieved, while 80% capacity can just discharge a whole night.With reference to 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 and works a whole night,
Main storage battery can be charged continuous two daytimes.After secondary battery works a whole night, daytime main storage battery and secondary battery
Charging simultaneously, that is to say, that in the case that evening on the same day assumes that secondary battery is not full of, main storage battery works a whole night, secondary
Accumulator can fill two daytimes.The generated energy of solar panel is typically based on, under rainy weather, secondary battery needs 3
It can be full of, and storing electricity is discharged by an evening, that is, secondary battery is charged continuous 3 daytimes, and 2 evenings treat
Machine, works 1 evening, and main storage battery be then need 7 days it is fully charged, can be with continuous discharge 5 days, for main storage battery and secondary storage
Multiple authentication is circulated through as battery and confirms as great application breakthrough, realize 365 days bright lights, anti-overcast and rainy days are carried significantly
Rise, there is no concern that when winter or rainy season is experienced discharged or defective battery runs, reduce accumulator and fill deeply the deep number of times put, so electric power storage
Pond service life is original several times, and effectively improves the endurance and brightness of illumination of accumulator.
Although specifically showing and describing this utility model with reference to preferred embodiment, those skilled in the art should
This is understood, in the spirit and scope of the present utility model limited without departing from appended claims, in form and details
On this utility model can be made a variety of changes, be protection domain of the present utility model.
