There is the electric energy of constant voltage.
Fig. 4 is refer to, Fig. 4 is the three of the block diagram for the electric supply installation 10 that present pre-ferred embodiments provide.It is described
Electric supply installation 10 can also include the first charge management circuit 320 and the second charge management circuit 420.First Charge Management
Circuit 320 is electrically connected with the solar panel 100, first battery 330 and BMS processors 200.Described second fills
Fulgurite reason circuit 420 is electrically connected with the solar panel 100, second battery 430 and BMS processors 200.Below
Illustrate how the BMS processors 200 when the solar panel 100 is that load equipment 600 is powered, control the sun
Energy cell panel 100 charges to the battery 430 of the first battery 330 or second.
The solar panel 100 (for example can be moved to without sunlight, or by nothing due to itself movement by sunlight
It is inferior that sunlight is moved at sunlight) or the reason such as sun movement there is the situation of output voltage fluctuation, and only solar cell
When plate 100 is operated in best efficiency point, solar panel 100 could be powered with maximal efficiency.
The BMS processors 200 are according to the electricity of first battery 330 and the electricity of the second battery 430, described in control
Solar panel 100 charges to the battery 430 of the first battery 330 or second.Such as the electricity of the first battery 330
Amount is less than default electricity, and the electricity of the second battery 430 has reached the state of charging complete, and the BMS processors 200 then control
The solar panel 100 charges to first battery 330.
In an embodiment of the present embodiment, the BMS processors 200 are being detected to first battery 330
Or second battery 430 charged charging current increase, and the output voltage of the solar panel 100 reduce when, lead to
Crossing the charge management circuit 420 of the first charge management circuit 320 or second reduces the charging current, so that the sun
Energy cell panel 100 is operated in best efficiency point.
Specifically, because the BMS processors 200 and first battery 330, the second battery 430 are electrically connected with, because
This, the BMS processors 200 can obtain first battery 330, the charging current of the second battery 430 in real time.To described
The charging current increase that first battery 330 or the second battery 430 are charged, and the output of the solar panel 100 is electric
When pressure drop is low, the current working condition of the solar panel 100 off-target efficient point is characterized.And first charging
Management circuit 320 can be used for charging current of the adjustment to first battery 330, and second charge management circuit 420 can
For adjusting the charging current to second battery 430, therefore, the BMS processors 200 pass through first charging valve
The reason charge management circuit 420 of circuit 320 or second reduces the charging current, so that the solar panel 100 works
In best efficiency point.
In the another embodiment of the present embodiment, the BMS processors 200 detect the solar panel
During 100 output voltage increase, described fill is made by the charge management circuit 420 of the first charge management circuit 320 or second
Electric current increases, so that the output voltage of the solar panel 100 is reduced to best efficiency point.
In the another embodiment of the present embodiment, the BMS processors 200 detect the load equipment 600
When using voltage increasing, make to increase by the electric current of the voltage-regulating circuit 510, and pass through first charge management circuit
320 or second charge management circuit 420 reduce the charging current so that the output voltage of the solar panel 100
Recover to best efficiency point.
In the present embodiment, the use of load equipment 600 can not be met in the output voltage of the solar panel 100
During voltage, the BMS processors 200 adjust first battery according to the electricity of the battery 430 of the first battery 330 and second
330 and second battery 430 charging and discharging state.
Referring once again to Fig. 4, the electric supply installation 10 can also include the first charging control switch 310, the first battery is put
Electric control switch 340, the second charging control switch 410 and the second battery discharge controlling switch 440.First charge control is opened
310 are closed to be electrically connected with the solar panel 100, the first charge management circuit 320 and BMS processors 200.Described first
Battery discharge controlling switch 340 is electrically connected with first battery 330, BMS processors 200 and load equipment 600.Described
Two charging control switches 410 and the solar panel 100, the second charge management circuit 420 and BMS processors 200 are electrical
Connection.The second battery discharge controlling switch 440 and second battery 430, BMS processors 200 and the electricity of load equipment 600
Property connection.The BMS processors 200 are described below can not meet that load is set in the output voltage of the solar panel 100
Standby 600 when using voltage, how according to the electricity of the battery 430 of the first battery 330 and second adjustment first battery
330 and second battery 430 charging and discharging state.
If only one piece of battery is used for discharge and recharge, in the case where fluctuation occurs in the power of the electric energy of solar energy conversion, too
The electric energy that sun can convert is possibly used for being supplied to load equipment 600 and battery to be charged, it is also possible to it is served only for charging to battery,
Thus this block battery is caused in charged state and discharge condition frequent switching.For chemical energy battery, it can be greatly lowered
The life-span of battery.Because the service life of battery is represented by discharge and recharge number, therefore by making the first battery 330 and second
Battery 430 is full full of putting, and can extend the life-span of battery.
In the present embodiment, the BMS processors 200 are according to the electricity of the battery 430 of the first battery 330 and second,
By control first charging control switch 310, the second charging control switch 410, the first battery discharge controlling switch 340 and
The working condition of second battery discharge controlling switch 440, adjust the discharge and recharge shape of the battery 430 of the first battery 330 and second
State, to realize that full be full of of the first battery 330 and the second battery 430 is put.
Specifically, if the BMS processors 200 select first battery 330 to enter charged state, described second is selected
Battery 430 carries out discharge condition, and idiographic flow is as follows.
It is opening that the BMS processors 200, which control first charging control switch 310, control first electricity
Tank discharge controlling switch 340 is closed mode, thus, the electric energy that the solar panel 100 provides is filled through described first
Electric control switch 310, the first charge management circuit 320 flow to first battery 330, so as to enter to first battery 330
Row charging.Meanwhile the BMS processors 200 can be adjusted by controlling the working condition of first charge management circuit 320
The size of the whole charging current to be charged to first battery 330.Further, detected in the BMS processors 200
During 330 charging complete of the first battery, then it is closed mode to adjust the working condition of the first charging control switch 310.
It is closed mode that the BMS processors 200, which control second charging control switch 410, control second electricity
Tank discharge controlling switch 440 is opening, thus, second battery 430 is powered for the load equipment 600.Enter one
Step ground, when the electricity of second battery 430 is less than default electricity, the BMS processors 200 then adjust second battery
The working condition of discharge control switch 440 is closes, and it is opening to adjust second charging control switch 410, with right
Second battery 430 is charged.
Otherwise similarly.
Hereby it is achieved that full be full of of the first battery 330 and the second battery 430 is put, the service life of battery is extended.
