Large-capacity accumulator modularized discharging device

The utility model provides a large-capacity storage battery modularized discharging device, relating to a discharging device which can achieve large-capacity storage battery modularization according to the battery capacity. The utility model includes a plurality of same discharging modules in parallel connection; the discharging module consists of a major discharging loop and a feedback loop in parallel connection with the major discharging loop. Aiming at large-capacity battery discharging, the utility model can select the number of discharging modules according to the number of batteries; each module adopts a same current-type control circuit and an independent discharging loop, which can connect the modules in parallel; then the same current set value is added to each module, thus achieving the same discharging current of each module and discharging current share, converting large current into small current of each module, realizing the equipment miniaturization and enhancing the equipment reliability.
