Novel double-flow cross-test capacity check testing machine for storage battery pack

Abstract

The invention provides a novel double-flow cross-test capacity check testing machine for a storage battery pack. The testing machine structurally comprises a carrying handle, a display screen, a discharge rate adjustment rotator, a double-flow cross-test device, a capacity check test box body and a high discharge side fan, wherein the bottom end of the carrying handle is fixedly connected to the top end of the capacity check test box body in an electric welding mode; the display screen is arranged on the front end face of the capacity check test box body in an inlaid manner; and the double-flow cross-test device is arranged in the front end face of the capacity check test box body in an embedded mode. During a process of carrying out connection on a sub-interface of a main control storagebattery pack through a conductive rod, the current reserves of a part of the main control storage battery pack can be supplemented, so that the control handover can be completed orderly, the capacitycheck tests of all storage battery packs in a switching station can be completed in a short time, the discharge in the capacity check test can be converted and recycled, the loss condition of the capacity check currents of the same number can be reduced, and the usage state of the main control storage battery pack can be quickly restored.

Description

technical field [0001] The invention belongs to the field of accumulators, and more specifically relates to a novel accumulator pack double-flow cross-measuring nuclear capacity testing machine. Background technique [0002] For the battery packs in the power switching station, in order to ensure safety, it is necessary to check the internal capacity of the working battery packs in the station every year. Since the stations in the station are not allowed to stop, a backup battery is usually set up for detection and supply to supply the battery packs in the station. The battery pack in the test can maintain the normal power supply demand in the test. [0003] Based on the above description, the inventors found that the existing new battery pack double-flow AC measurement and nuclear capacity testing machine mainly has the following deficiencies, such as: [0004] Since the capacity of the backup battery pack is difficult to compare with that of the main control battery pack,...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a new battery pack double-flow cross-measuring nuclear capacity testing machine to solve the problem that the capacity of the backup battery pack is difficult to match with the existing The main control battery pack is used for comparison. After the main control battery pack is discharged, it needs a period of time for internal power accumulation. The backup battery pack needs to be maintained until it completes the power supply before switching power supply. After the transfer is completed, the capacity can be checked by replenishing the power supply again, and the two-way loss of the power supply consumes energy uselessly, and at the same time it takes a lot of time in the same switching station to complete the storage of all internal batteries.
