Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the outdoor electric power system of the utility model based on storage battery and super capacitor.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail:
As shown in Figure 1, the outdoor electric power system of the utility model based on storage battery and super capacitor, it comprises solar panel 1, power-supply controller of electric 2, super capacitor 3 and storage battery 4, solar panel 1 converts solar energy into electrical energy, and by power delivery to power-supply controller of electric 2, power-supply controller of electric 2 is connected with storage battery 4 with super capacitor 3 respectively, and power-supply controller of electric 2 is also connected with outdoor study equipment 5.
Described power-supply controller of electric 2 is provided with the diverter switch 6 that super capacitor 3 and storage battery 4 exchange.
On described power-supply controller of electric 2, be also provided with the voltage detection unit 7 of the corresponding super capacitor 3 of difference and storage battery 4.
During the outdoor electric power system work based on storage battery and super capacitor of the present utility model, solar panel 1 first converts solar energy into electrical energy, and by power delivery to power-supply controller of electric 2, power-supply controller of electric 2 is respectively super capacitor 3 and storage battery 4 chargings.After super capacitor 3 is full of, stable voltage is provided to power-supply controller of electric 2, power-supply controller of electric 2 is again for outdoor study equipment 5 provides stable voltage.
When night or cloudy day, solar panel 1 cannot be changed enough electric energy, and power-supply controller of electric 2 all to super capacitor 3 and storage battery 4 chargings, after super capacitor 3 is full of, provides stable voltage to power-supply controller of electric 2 electric energy of solar panel 1 conversion.When super capacitor 3 discharges into a certain degree, the lower voltage of 3 pairs of power-supply controller of electric of super capacitor, 2 outputs, at this moment the voltage that in power-supply controller of electric 2, the voltage detection unit 7 of corresponding super capacitor 3 detects super capacitor 3 is lower than a certain set point, for example, during 12V, start the diverter switch 6 in power-supply controller of electric 2, super capacitor 3 quits work, and by storage battery 4, provides stable voltage for power-supply controller of electric 2.
Along with the electric discharge of storage battery 4, the supply power voltage of storage battery 4 reduces.Capacitance in storage battery 4 lower than total capacitance 20% time, storage battery 4 lower voltages are to liminal value; In addition, when the working temperature of storage battery 4 is lower than 0 ℃ or during higher than 50 ℃, storage battery 4 spread of voltages or be reduced to liminal value.The voltage that the voltage detection unit 7 of corresponding storage battery 4 detects storage battery 4 in power-supply controller of electric 2 is down to liminal value (for example 10.6V) or when abnormal, storage battery 4 quits work.If storage battery 4 in its capacitance 20% time lower than total capacitance discharge, storage battery 4 carries out deep discharge, can greatly reduce the useful life of storage battery 4.And the utility model adopts above design, avoided storage battery 4 to carry out deep discharge, extend the useful life of storage battery 4.In addition, storage battery 4 is under the environment lower than 0 ℃, and activity decreased, cannot provide stable voltage; And storage battery 4 is worked under the environment higher than 50 ℃, stable voltage cannot be provided, and greatly reduce useful life, design of the present utility model also avoided storage battery 4 lower than 0 ℃ or higher than the environment of 50 ℃ under work, further extended the useful life of storage battery 4.
