Abstract

The invention relates to a storage battery activation grid-connected discharging device which comprises a main circuit unit and a control unit. The main circuit unit comprises a booster circuit, an inverter circuit and a filter circuit which are sequentially connected, a storage battery is connected with an input end of the booster circuit, an output end of the filter circuit is connected with a power grid, the control unit comprises a controller and a driving circuit, the controller is connected with the driving circuit in a controlling manner, and the driving circuit is used for driving power tubes in the booster circuit and the inverter circuit. By the aid of the booster circuit, the inverter circuit and the filter circuit, electric energy of the storage battery is fed back to the power grid, a traditional heating discharging method is replaced, energy loss is greatly decreased, and the national policy of energy conservation and emission reduction is met.

Description

technical field [0001] The invention relates to a storage battery activation grid-connected discharge device. Background technique [0002] In the industrial field, batteries have always played an important role as a backup power source. In the daily use and maintenance of the battery, in order to detect the state of the battery capacity and activate the battery, a discharge test must be carried out regularly. With the national policy of "energy saving and emission reduction" deeply rooted in the hearts of the people, energy-fed battery discharge devices have become a research hotspot in recent years. [0003] The battery needs to be maintained for a period of time, and it needs to be charged and discharged for activation, and the battery also needs to be periodically discharged by nuclear capacity and internal resistance measurement. The traditional battery activation and discharge process is to consume electric energy through loads such as resistors and electric furnaces...
