The embodiment of the utility model provides a high-efficient tank circuit's theory of operation as follows: referring to fig. 2, after receiving sunlight, a photovoltaic cell converts light energy into electric energy, the electric energy is transmitted to a first chopper Q1 through a first diode D1, and after chopping and voltage transformation are performed by a first chopper Q1, current is transmitted to a second capacitor C2, a second chopper Q2 and a fourth chopper Q4, a second diode D2 plays a role in reverse breakdown and voltage stabilization, voltage of the current chopped and voltage transformed by the first chopper Q1 can be stabilized, a part of current can be stored in the first capacitor C1 when the voltage of the photovoltaic cell is too large, so that voltage stabilization of the photovoltaic cell is performed, a certain amount of electric energy is stored by the second capacitor C2, and the received current is transmitted to a super capacitor group C after being chopped and voltage transformed by the second chopper Q2 and stored (at this time, a third chopper Q3 is turned off); the current transmitted to the fourth chopper Q4 is subjected to chopping and voltage transformation (at the moment, the fifth chopper Q5 is closed), and then is transmitted to the lead-acid battery pack B for storage. If the voltage of the lead-acid battery B is too large, a part of the current can be also transmitted to the third capacitor C3 for storage, so as to stabilize the voltage of the lead-acid battery B. In the whole charging process, the switch S is in an off state, and the light generation resistor RL does not consume any electric energy. When charging is completed, the first chopper Q1, the second chopper Q2 and the fourth chopper Q4 are all closed, and the third chopper Q3, the fifth chopper Q5 and the switch S are all closed. At this time, the current stored in the second capacitor C2 flows to the light emitting resistor RL to supply power to the light emitting resistor RL (i.e. the street lamp is on); the super capacitor group C also supplies power to the light-emitting resistor RL through the diode of the second chopper Q2, and the current output by the super capacitor group C is chopped and transformed due to the opening of the third chopper Q3, so that the voltage Vc of the super capacitor group C can be maintained at an ideal value; the lead-acid battery pack B supplies power to the light-emitting resistor RL through the diode of the fourth chopper Q4, and the current output by the lead-acid battery pack B is chopped and transformed due to the opening of the fifth chopper Q5, so that the voltage Vb of the lead-acid battery pack B can be maintained at an ideal value. Through the second capacitor C2, the super capacitor group C and the lead-acid battery group B supply power to the street lamp (namely, the light-emitting resistor RL) together, so that the light-emitting current requirement of the street lamp can be ensured, and the light-emitting timeliness of the street lamp can be ensured.
The embodiment of the utility model provides a high-efficient energy storage circuit and solar street lamp still have following characteristics: the super capacitor group C realizes charge and discharge through adsorption and desorption of conductive ions on electrodes, and the charge and discharge process is basically not limited theoretically due to the huge surface area of electrode materials, has high power density which is about 20 times of that of a lead-acid storage battery, and has high power output and input capacity; and secondly, the cycle life is long, the maintenance cost is low, and the solar street lamp using the super capacitor group C and the lead-acid battery B as the energy storage device can reduce the times of maintaining the energy storage device and reduce the maintenance cost. The service life of the super capacitor C is more than 10 years, and the service life of the super capacitor C can be more than 20 years under the low-temperature condition; the charging and discharging times are more than 100 ten thousand. The energy storage device of the whole solar street lamp can be used with less maintenance or even without maintenance, thereby achieving the requirement of reducing the cost; and thirdly, the charging and discharging efficiency is high, the equivalent series internal resistance and the charging and discharging time constant of the super capacitor group C are very small, so that the super capacitor group C has very high charging and discharging efficiency, and the charging and discharging cycle efficiency can reach more than 90%. The charge-discharge cycle loss of the lead-acid battery B is 20-30%, while the super capacitor group is only 10%. Fourthly, the charging and discharging speed is high, and the charging and discharging efficiency is relatively high due to the fact that the equivalent series internal resistance of the super capacitor group C is small, the charging and discharging time constant is small. In the process of charging and discharging, the lead-acid battery B is limited by the diffusion speed of ions participating in electrochemical reaction, the charging and discharging speed is much slower than that of the super capacitor group C, and the super capacitor group C can finish rapid charging or discharging within tens of seconds or minutes; fourthly, the environment is friendly, and the material used by the super capacitor group C is safe, non-toxic and environment-friendly. The electrode material is mainly composed of carbon, does not contain heavy metals such as lead, cadmium and the like, and does not cause harm to production or users and pollution to the environment. Moreover, the supercapacitors C themselves have no mechanical parts and do not produce noise pollution. The super capacitor group C is used as an energy storage device of the solar street lamp, and the energy-saving and emission-reducing indication is met; sixthly, the temperature characteristic is good, in the exchange process of energy, the super capacitor group C does not generate electrochemical reaction, so that the dependence on the environmental temperature is relatively small, and the super capacitor group C has good high and low temperature performance, can normally work within the temperature range of-40 ℃ to +70 ℃, and does not generate obvious performance reduction, and the characteristic determines that the super capacitor group C can meet the use in regions with large temperature difference, and the energy stored in the lead-acid battery B is difficult to discharge when the temperature is lower than 5 ℃; when the temperature is lower than minus 5 ℃, electric energy can not be discharged on the basis. Seventhly, weak and small current can be absorbed, and the phenomenon that the electric energy of the lead-acid battery B is insufficient usually occurs due to climate change such as yin, rain, snow, sunny, cloudy and sunshine in the south and north and geographical environment; the lack of power is also typically present due to the life of the lead-acid battery B itself. The principle of the combined use of the super capacitor group C and the lead-acid battery B is that the super capacitor group C can absorb weak and small current, when the current generated by the solar panel is not large enough, the super capacitor group C is charged firstly, and then the electric energy in the super capacitor group C is controlled to be stably charged into the lead-acid battery B. The electric energy which cannot be absorbed by the lead-acid battery B is supplemented into the lead-acid battery B, so that the lead-acid battery B is ensured to have enough electric energy to be supplied to the street lamp for use, the service life of the lead-acid battery B is ensured, and the aim of ensuring the stability of the whole solar street lamp system is fulfilled.
