Embodiment
Below, come the present invention is done further explanation in conjunction with accompanying drawing:
As shown in Figure 1; The charge-discharge system of light-electricity complementary battery of the present invention comprises solar energy module, civil power module, micro treatment module, LED light module, ten battery pack, load end; Said micro treatment module is a monolithic computer; Said solar energy module is electrically connected on said monolithic computer, and is that electric energy inputs to said monolithic computer with conversion of solar energy, and said civil power module is connected in said monolithic computer; Said civil power module comprises mains supply and rectifier, is that direct current inputs to said monolithic computer with the mains supply rectifying and wave-filtering; Said ten battery pack inside are equipped with battery manager, and said ten battery pack are connected in said monolithic computer respectively, and said load end and LED light module also are connected to said monolithic computer; Each battery pack is switched in the control of this monolithic computer or the civil power module is discharged to load end, and the control solar energy module is to each batteries charging, and the battery pack information of self and the battery manager that will obtain simultaneously is treated to signal; This LED light module then shows different indication informations according to the signal that obtains from monolithic computer.
The charge-discharge system of the light-electricity complementary battery of said structure is at first set first preset value, for example is 21V, sets second preset value again, for example for being full of.When carrying out work, monolithic computer detects the state of each battery pack, if having at least the voltage of a battery pack to be full of this moment; Then select battery pack that is full of and the battery pack that is higher than 21V to import electric energy to monolithic computer as power supply; The supply load end uses afterwards, and the solar energy module of monolithic computer control simultaneously charges for voltage successively less than the battery pack of 21V, if sunshine this moment is enough strong; The voltage of solar energy module is enough high; Also have residue when giving first batteries charging, the batteries charging of then being lower than 21V for second voltage simultaneously is if charge power supply also has residue; Then continue to be lower than the batteries charging of 21V for the 3rd voltage, by that analogy.When this battery pack was full of, solar energy module stopped to this batteries charging, and this battery pack can not be discharged to load end in by the solar energy module charging.When charge power supply voltage is enough high, can give a plurality of batteries chargings, and when charge power supply voltage is not high enough, then only give less batteries charging, can cooperate the difference of environment at sunshine to change, improved the adaptability of solar recharging.And if after the state-detection of monolithic computer to each battery pack; The voltage of the battery pack that this moment is all is all less than 21V; Then selecting the civil power module is that stand-by power supply is imported electric energy to monolithic computer, and its discharge of monolithic computer control is used to load end, after solar energy module is full of at least one battery pack; Stop the discharge of civil power module, switch back battery pack and be discharged to load end.
The charge-discharge system of the light-electricity complementary battery of said structure; When discharging, if employing is battery power discharge, monolithic computer can detect the state of each battery pack; Height according to the current potential of each battery pack sorts; To load end, the preferable employing of this each battery pack is the mode of discharge in turn according to current potential sequence discharge from high to low, is more preferably under only to have a battery power discharge in the discharge process simultaneously.Do not adopt discharge simultaneously, and adopt the aforesaid way discharge, can reduce the waste of discharge; Improve discharging efficiency; And in turn discharge can guarantee that each battery pack is average as far as possible and uses, and can be because of only not using certain several battery pack to cause battery pack aging rapidly, the useful life of having improved battery pack.Above-mentioned each battery pack can not receive the charging of solar energy module when being discharged to load end.
The charge-discharge system of the light-electricity complementary battery of said structure is when work; The state information of each battery pack that monolithic computer will obtain from battery manager at any time after treatment; Be transferred to the LED light module, the LED light module shows different monolithic computers and battery pack state information.For example: the corresponding monolithic computer of LED light module is provided with 5 LED lights, and No. 1 green light is bright, and charging is accomplished, No. 2 Blink greens, and expression regular picture, No. 3 orange lamp is bright, and expression charges normal, and No. 4 red light is bright, the alarm of expression low pressure, No. 5 red light dodges system exception; Corresponding each battery pack is provided with LED light respectively, and this LED light green light is bright, representes that this battery pack normally uses; This LED light Blink green; Represent that this battery pack is in low-pressure state, this LED light green light puts out, and representes that this battery pack is in unusual or complete discharge condition.Can also in the LED light module, install a buzzer additional, when abnormality appearred in the battery more than 4 groups, buzzer was promptly emitted alarm song.
Above-mentioned LED light module can reflect the work state information of the charge-discharge system of this light-electricity complementary battery well, and can find the fault point of the charge-discharge system of this light-electricity complementary battery effectively, and gets rid of fault.
