Embodiment 1

[0067] Design a low-power energy storage control device for wind power systems, and use this device together with two 12V100Ah lead-acid maintenance-free batteries, 100W wind power components and 50W LED lamps (discharge load 10) to form a city called road Wind power system with wind energy street lights.

[0068] The energy storage control device includes a measurement and control device 2, a wind power input terminal 3, a power output interface 5, a wind power collection device 6 and a discharge controller 8b, wherein the discharge controller 8b is a constant current power controller, and its power input terminal is electrically connected to The two poles of the battery pack 4 composed of two batteries connected in series, the power output end is electrically connected to the LED lamp, and the signal input end is connected to the measurement and control device 2; the measurement and control device 2 is electrically connected to the power output end of the wind power component...

Embodiment 2

[0075] Change the two 12V100Ah lead-acid maintenance-free storage batteries described in Example 1 into four 6V100Ah lead-acid maintenance-free storage batteries, and connect the four batteries in series to form the two extremes of the storage battery pack 4 and the three series taps in the middle, totaling five The external terminal; the power output interface 5 is correspondingly composed of 5 electronically controlled logic switches, and the measurement and control device 2 is respectively connected to the two extremes of the battery pack with 4 batteries connected in series and the middle 3 series tap terminals through the 5 electrically controlled logic switches. The connection method of the 5 electronically controlled logic switches and the 5 external terminals of the battery pack connected in series, and the rest of the connection methods of the energy storage control equipment and the wind power system are similar to those in Embodiment 1.

[0076] In this embodiment, d...

Embodiment 3

[0079] Embodiment 2 is further modified, and four 6V100Ah lead-acid maintenance-free batteries are replaced by twelve 2V100Ah single lead-acid batteries. The external terminal of the battery module; the power output interface 5 is correspondingly designed to consist of 13 electronically controlled logic switches.

[0080] In this embodiment, the 13 electronically controlled logic switches of the power supply output interface 5 perform corresponding on / off combinations under the programming control of the measurement and control device 2, so that the charging intensity of the single battery can be realized indirectly when the wind energy is weaker. Improvement, to further utilize the electric energy obtained by the wind power components in the weak wind environment, and at the same time implement time-distributed and evenly distributed charging for the 12 single batteries, so as to achieve the purpose of effective battery maintenance.
