Abstract
The utility model relates to a high-performance charging controller of a photovoltaic power generation system. The high-performance charging controller consists of an electronic component, an instrument, a relay, a switch and a peripheral accessory. The charging controller adopts a self-research temperature compensation control circuit as the core part, adopts a voltage-stabilizing diode and a thermistor as the compensation components and utilizes a follower amplifier for realizing the temperature compensation for the backward stage. The high-performance charging controller can not only regulate the photovoltaic power generation system with high precision, but also regulate the photovoltaic power generation system with wide compensation range, so that the charging for a storage battery can be faster, more stable and efficient, and the loss can be reduced in the charging process, so as to protect the storage battery and prolong the service life of the storage battery.
Description
Technical field
The utility model relates to solar energy utilization field, especially high-performance optical photovoltaic generating system charge controller.
Background technology
Nowadays, the use of solar power system is more and more general.The solar energy electroplax of every day all charges repeatedly to battery, if the energy of battery storage is too much, will cause over-charging of battery; When perhaps it discharges, do not control, occur over-discharge can easily; Existing solar energy system equipment, if overcharge, battery temperature can raise, and does not have the battery circumferential ambient temperature to detect the protection of control circuit, the too high meeting of battery temperature influence the performance of battery.In the prior art, what have has over-charge protective to battery, and what have had the protection of putting to battery, but lacks the battery overheat protector.Like this, battery can be subjected to bigger influence all the time and reduce the life-span.
Summary of the invention
In order to overcome the problem that prior art exists, the utility model provides a kind of high-performance optical photovoltaic generating system charge controller that temperature-compensation circuit is housed.
The technical scheme that its technical problem that solves the utility model adopts is: this high-performance optical photovoltaic generating system charge controller mainly is made up of electronic devices and components, instrument, relay, switch and peripheral accessory.High-performance optical photovoltaic generating system charge controller adopts the temperature compensation control circuit of independent research as core component, adopts voltage stabilizing didoe and thermistor device by way of compensation, is undertaken the temperature-compensating of level afterwards by follow-up amplifier.Because diode is relatively stable, the precision height, the heat energy resistance range is wide, so can obtain different compensation by adjusting resistance.By follow-up amplifier back level is regulated, can be to high the regulating of precision prescribed, also can be to requiring wide the regulating of compensation range, thus for storage battery provides best charging current and voltage, be charge in batteries fast, steadily, efficiently.
The beneficial effects of the utility model are: make charge in batteries quicker, steady, efficient, and reduce loss in charging process, protection storage battery, the useful life of prolongation storage battery.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model principle schematic.
Among the figure 1, Ub-battery-operated voltage, Us-solar cell output voltage, D-voltage stabilizing didoe, the equal effect pipe of Q-, U-amplifier, Ua-amplifier U in-phase end current potential, Um-amplifier U end of oppisite phase current potential, Uk-amplifier U output current potential, R1-R3-divider resistance, RT-thermistor.
Embodiment
This high-performance optical photovoltaic generating system charge controller mainly is made up of electronic devices and components, instrument, relay, switch and peripheral accessory.Charge controller adopts the temperature compensation control circuit of independent research as core component, adopts voltage stabilizing didoe and thermistor device by way of compensation, is undertaken the temperature-compensating of level afterwards by follow-up amplifier.
In the embodiment shown in fig. 1, the concrete method of attachment of temperature-compensation circuit is as follows: thermistor RT connects with voltage stabilizing didoe D, two groups of resistance are in parallel with accumulator output end respectively, the output of two groups of resistance links to each other with negative input with the forward of amplifier U respectively, the output Uk of amplifier U is connected with the grid of field effect transistor Q, and the grid of field effect transistor Q is connected with the output of control circuit.Thermistor RT does sensing device and measures battery temperature on every side to regulate electric current; when temperature requires above regulation; thermistor RT changes the antiphase current potential of amplifier U in the controller; thereby field effect transistor Q is disconnected; make storage battery stop charging; the protection battery keeps battery to be in the good operation temperature range, thereby prolongs battery useful life.
