Problems solved by technology
[0006]1. The current electronic metering meter has to be billed no matter whether the current is in or out, so the discharge back to the grid will cause secondary billing, resulting in a large increase in electricity bills;
[0007]2. The discharge directly returned to the power grid without any treatment will cause secondary pollution to the power grid, resulting in serious distortion of the power grid, and even cause power line failure

Embodiment Construction
[0032] The preferred embodiment of the present invention will be described in detail below in conjunction with accompanying drawing:
[0033] Such as figure 1 The shown public bus energy-saving recovery battery charging and discharging power supply mainly includes a main power supply unit 1 , a common bus unit 2 , multiple single-loop control units 3 , a discharge module 4 and a man-machine control module 5 . Among them, the main power supply unit 1 is mainly composed of a transformer 11 and a rectifier 12 , the three-phase alternating current is connected to the transformer 11 through a control switch, and the voltage converted by the transformer 11 is output through the rectifier 12 . The positive and negative input terminals of the common bus unit 2 are electrically connected to the output terminal of the main power supply unit 1 for receiving the converted DC power.
[0034] There are multiple single-loop control units 3, and the multiple single-loop control units 3...

The invention relates to common bus energy-saving recovery type storage battery charging-discharging power supply equipment which comprises a main power supply unit, a common bus unit, a single-circuit control unit, a discharging module and a human-machine control module, wherein the single-circuit control unit is used for controlling the charging and the discharging of a corresponding storage battery according to a command of a human-machine control unit; when the storage battery is required to be charged, power energy is output to the corresponding storage battery from a bus unit; when the storage battery is discharged, the power energy is returned to the bus through the single-circuit control unit; when the storage batteries of different single-circuit control units are simultaneously charged and discharged, energy discharged by the storage batteries is directly used for charging other storage batteries; and when discharging energy received by the bus is greater than charging output energy, the discharging module is started to work and consume excessive energy in a heat energy form. Compared with the traditional equipment, the common bus energy-saving recovery type storage battery charging-discharging power supply equipment has the advantages that the used electric expenses are greatly reduced by about 30 percent; and during discharging, secondary pollution to a power grid is avoided.
Description
[0001] technical field [0002] The invention relates to a charge-discharge power supply equipment used in storage battery formation process. [0003] Background technique [0004] The storage battery is a battery that can be repeatedly charged and discharged. It usually uses a lead plate filled with spongy lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and dilute sulfuric acid as the electrolyte. When charging, an external DC power supply is usually connected to the battery for charging, so that the electrical energy is converted into chemical energy and stored; when discharging, the electrical energy is released from the battery. The storage battery has the advantages of good reversibility, stable voltage characteristics, long service life, wide application range, convenient power supply, safety and reliability, etc. With the rapid development of modern industry, the battery industry plays an increasingly important and fu...
