Description
Technical field
The utility model relates to a kind of portable emergency electric power system, especially utilizes solar panel to produce electric energy, and the solar portable formula emergency power supply system of emergency lighting and supply of electric power is provided for the scene of rushing to repair.
Background technology
Scene such as rush repair equipment, rescue and relief work can't normally obtain supply of electric power from electrical network out of doors, thereby has demand widely for the emergency lighting that is independent of electrical network and power supply in these occasions.
Existing solution is to utilize diesel engine generator and energy storage device such as lead acid accumulator or lithium battery that energy is provided.But, when emergency power supply system when energy is used up, can not be on the spot makeup energy in time, often increase the stored energy capacitance of equipment with the portability of sacrificing emergency power supply system.
At present, though the Emergency power supply unit that utilizes solar panel to guarantee the energy supply is arranged, can reduce stored energy capacitance to a certain extent, improve the portability of system, but the energy conversion efficiency between the photoelectricity is not high enough, can not amplitude peak ground be electric energy with conversion of solar energy.
Summary of the invention
The purpose of this utility model, a kind of solar portable formula emergency power supply system is provided in order to address the above problem exactly, this emergency power supply system not only has good portability, and can also guarantee energy conversion efficiency between the high photoelectricity, realize MPPT maximum power point tracking (MPPT), amplitude peak luminous energy is converted into electric energy, is applied to the emergency service occasion.
The purpose of this utility model is achieved in that
A kind of solar portable formula emergency power supply system of the present utility model, the charger that comprises the lithium battery group, links to each other and link to each other with civil power with this lithium battery group and DC converter, AC converter and the LED lamp that links to each other with described lithium battery group respectively, described solar portable formula emergency power supply system also comprise solar panel and the charge controller that links to each other with the lithium battery group with described solar panel respectively.
Above-mentioned a kind of solar portable formula emergency power supply system, wherein, described charge controller is the charge controller that when the sufficient and described lithium battery group electric weight of illumination is not enough the lithium battery group is carried out the maximum power charging.
The utility model solar portable formula emergency power supply system can guarantee that solar panel is operated in optimum state in the process of charging normal, and can improve the efficient of solar panel charging again, has improved the portability of emergency power supply system.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the Buck circuit theory diagrams.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See also Fig. 1, the utility model solar portable formula emergency power supply system, charger 2, the DC converter 3 that links to each other with lithium battery group 1 respectively, AC converter 4 and the LED lamp 5 that comprises lithium battery group 1, links to each other and link to each other with civil power with this lithium battery group 1, solar panel 6 and the charge controller 7 that links to each other with lithium battery group 7 with solar panel 6 respectively.
Under the normal condition, utilize the city of 220V to be electrically connected charger 2, charge to lithium battery group 1.Can't obtain under the situation of civil power solar panel 6 at the utility model solar portable formula emergency power supply system) connect charge controller 7, in time charge on the spot to lithium battery group 1.
The utility model can satisfy different needs for electricity.DC converter 3, AC inverter 4 are electrically connected with lithium battery group 1 respectively, for lithium battery group 1 provides the direct current of 5V and the alternating current of 220V respectively; Choose adaptive direct-current LED lamp 5 and be electrically connected with lithium battery group 1, emergency lighting can be provided.
MPPT maximum power point tracking can realize in the following manner: calculate charge power P (k) by sampling charge controller 7 output voltage V (k), electric current I (k), and compare with the charge power calculated value P (k-1) of a last sampled point, and determine the mobile direction that changes of output voltage according to the situation that voltage moves.Move in circles, guarantee that charge power is stabilized near the maximum, realize MPPT maximum power point tracking.
The change of output voltage realizes by the Buck circuit.In Fig. 3, when the Q1 conducting, solar panel 6 as power supply to equivalent load R
0Power supply, the electric current inductance L 1 of flowing through is load R in the time of to capacitor C 1 charging
0Energy is provided; When Q1 turn-offs, 1 couple of load R of capacitor C
0Discharge, electric current is by 1 couple of load R of sustained diode simultaneously
0Power supply.Output voltage is D*Vs, and wherein D is the duty ratio of PWM ripple shown in Fig. 3.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
