Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-4, a kind of cloud energy storage device, including multiple energy storage device monomers 1, the positive pole of the plurality of energy storage device monomer 1 is connected by conductor in parallel, the negative pole of multiple energy storage device monomers 1 is connected by conductor in parallel, described energy storage device monomer 1 includes super energy carrier 2, converter 3 and charging device 4, the positive pole of described super energy carrier 2 connects the P end of frequency changer direct current bus, the negative pole of super energy carrier 2 connects the N end of frequency changer direct current bus, the positive pole of described charging device 4 connects the positive pole of super energy carrier 2, the negative pole of charging device 4 connects the negative pole of super energy carrier 2, described super energy carrier 2 is super capacitor or superbattery.
If there is N platform elevator in a house, every elevator has an energy storage device monomer 1, super energy carrier 2 in energy storage device monomer 1 is attempted by the dc bus of converter 3, if the energy storage device monomer of N platform elevator 1 is respectively A1, A2, A3 ... An, and super energy carrier 2 therein is attempted by the dc bus of converter 3 of this elevator respectively, again this n energy storage device monomer 1 is together in parallel and realizes resource-sharing, in this N platform elevator, always there are some elevators in electricity consumption, it is assumed that A1, A3, A5 ... An-1 is in electricity consumption；And other elevators are in generating, such as A2, A4, A6 ... An is in generating；A1, A2, A3 ... An is together in parallel, the then elevator of generating state, the electric energy sent can be directly fed to the elevator of electricity condition by connecting line, the balance of nature of acquirement state is unlikely to overflow and waste, and the supplementary of the electric energy that another part electricity consumption elevator sends owing to obtaining power-generating elevator is unlikely to exhausted and stops ladder, so, no matter it is electricity consumption or generating, electric energy in super energy carrier 2 is all fully utilized, reach relative balance of nature, also can alleviate the load of energy storage device thus the deployment cost of super energy carrier 2 can be substantially reduced.
