Waste electric energy recycling device

Abstract

The invention discloses a waste electric energy recycling device which is used for recycling waste electric energy generated in a discharging process, but has no influence to the original aim of a burn-in test. The waste electric energy recycling device comprises a series circuit control unit, a current limiting control unit and an electric power converting unit, wherein the series circuit control unit capable of serially connecting a plurality of groups of electric energy modules to form a proper voltage condition and also disconnecting a single or the plurality of groups of electric energy modules from a series loop; the current limiting control unit is connected with the series circuit control unit and used for setting and limiting the current output of the electric energy modules; and the electric power converting unit is connected with the current limiting control unit and used for converting direct current electric energy into alternating current electric power and providing the alternating current electric power for an actual load. Therefore, the waste electric energy consumed by the original dummy load is recycled and then converted into effective electric power to be fed to an electric power network system to be established so as to be recycled; the electric energy consumption cost in the packaging process of the electric energy modules is reduced; and double benefits of energy saving and high efficiency for a process are achieved.

Description

technical field [0001] The invention relates to a waste electric energy recovery and reuse device, in particular to an electric energy recovery and reuse device which is used to recover waste electric energy in the discharge process and does not affect the test of the original burning machine. Background technique [0002] Electrical energy components such as batteries or battery modules or power supplies must pass a burn-in test during the packaging and manufacturing process. In the burn-in test process, it is generally necessary to charge the power components, and then use the dummy load resistor to release the stored electric energy of the power components. Through the charging and discharging cycle process of the power components, the performance verification of the power components is carried out. [0003] As shown in Figure 3, it is a schematic diagram of the application status of the burn-in equipment platform of the battery module. Generally, the burn-in test unit s...

Problems solved by technology

However, in such a test process, the total amount of electric energy consumed by the dummy load resistor is quite considerable, and the waste of energy consumption and the proportion of the manufacturing process cost are all unfavorable means or methods.

Therefore, the commonly used ones cannot meet the needs of users in actual use.
