The invention discloses a multi-unit parallel heavy-current storage battery charge-discharge control system which belongs to storage battery charge-discharge test equipment. The invention aims to provide equipment which not only can be used for the test of a single storage battery, but also can provide parallel heavy current test for certain storage battery. The charge-discharge control system comprises N storage batteries and load units; various load units are connected with the storage batteries; each storage battery (1) is communicated with the load unit (4) corresponding to the storage battery (1) through each communicated tool cabinet (2); a state switch (8) of the communicated tool cabinet (2) is connected with the load unit (4) corresponding to the communicated tool cabinet (2); a first tool cabinet (4) and a last tool cabinet (4) are connected by two serially-connected parallel tool cabinets (3); middle load units (4) are connected between the two serially-connected parallel tool cabinets (3) respectively through parallel tool cabinets (3); the state switch (8) of the parallel tool cabinet is connected with the corresponding tool cabinet (4) through a communication cable (6); negative electrodes of various storage batteries (1) are connected in parallel; and various load units (4) are connected with a main controller (5) through a communication bus (9).
Description
Technical field: [0001] The invention relates to a storage battery testing device, in particular to a large-scale storage battery testing device. Background technique: [0002] At present, there are two main methods for large-scale battery testing: [0003] 1) Silicon rectifier charging and carbon resistance discharging are characterized by manual operation, which has defects such as low charging accuracy, narrow adjustment range, and large errors. [0004] 2) The other is to use single-unit charging and discharging equipment to charge and discharge. The disadvantage is that when multiple batteries need to be tested, due to the large size, heavy weight, and inconvenient handling of large batteries, multiple specialized test equipment are required ,high cost. Invention content: [0005] Aiming at the above-mentioned defects existing in the prior art, the present invention aims to provide a charging and discharging test system that can independently conduct charge and disc...
