In supply module, owing to adopting accumulator to carry out store electrical energy, must carry out additives for overcharge protection and over to these accumulators, in order to extend battery, must use Intelligent Charge-control System, its major function comprises:
1, additives for overcharge protection,
In the time that voltage has exceeded final charging voltage, battery just starts to produce gas.This process and temperature have very large relation, and final charging voltage value is regulated according to environment temperature automatically by built-in sensor, even if still reach the battery of final charging voltage, is not also full of completely.Therefore electric current should not be cut off, and this Time Controller reduces the electric current that flows into battery as far as possible, is no more than final charging voltage to control, and this process is called IU charging.IU charging is charging modes the most stably, and reducing of electric current is that extremely fast of short duration short circuit (pulse width modulation) by solar components realizes.
2, gassing produces gas regulation,
Final charging voltage changes along with the variation of discharge level, while there is not gassing reaction, just likely forms the acid solution layering that one deck is very harmful when a lead-acid battery use long period.By limited controllable gassing, can avoid the formation of acid solution layering, gassing regulatory function that Here it is.Gassing regulate temporary close overcharge protection until reach so-called final charging voltage, gassing regulates in addition also can increase the final charging voltage of battery at high circulation time, breaks the memory effect of lead-acid battery.By this and function temperature close association, the capacity of battery can be utilized more fully, and the life-span of accumulator also increases relatively.
3, over,
If battery does not have the over equally can be damaged yet.When voltage is during lower than minimum sparking voltage, controller can automatically cut off load and protect battery not by overdischarge.In the time that solar components continues battery charging to reach the turn-on voltage that controller sets, load is also switched on again subsequently.
4, system charging and discharging state shows,
This controller has a green and one can be by the red light emitting diode that crossfades into green (altogether through 10 kinds of different colours) through Huang.When solar components produce power, green LED is lighted; In the time that controller starts to limit charging current or while charging, this LED flash variable color.The effective different color of light-emitting diodes represents different voltage, and before load is cut off, it starts quick flashing, in the time that load is cut off, dodges slowly.
The solar panel this time adopting is by standard GB/T/T9535-1998, and technical parameter is as follows:
Model: 80 (17.2) P443X1173;
Peak power (Wp): 80;
Short-circuit current (Isc): 5.19;
Open-circuit voltage (Voc): 22.00;
