The utility model provides a connecting bar resistance online testing system used for online testing and enabling people to know the resistance situation of the battery cell set connecting bar instantaneously, and avoiding the ripple interference of a charging set and various electromagnetic interferences; the connecting bar resistance online testing system comprises a monitoring host, an internal resistance load controlled by the monitoring host for the selective discharging of the battery cell segment tap connection, and a connecting bar voltage detection unit used for correspondingly the voltage of the segments.
Description
[technical field]
The utility model belongs to the accumulator testing technical field, particularly a kind of connection strap resistance Online Transaction Processing, and native system can be used for the resistance situation of at-once monitor battery pack connection strap.
[background technology]
The size of connection strap resistance is of crucial importance for the safe operation of accumulator in the battery pack, and excessive connection strap resistance may set off an explosion or fire when battery discharging.Along with industrial automatization improves constantly, higher for the accumulator dependence of doing the back-up source use, the user presses for the resistance situation that the battery pack connection strap is known in instant understanding.Use accumulator connection strap resistance test instrument mostly to be non-instant off-line test system at present, the portable accumulator connection strap resistance test instrument of off-line type of widespread use can not satisfy the instant needs of understanding of aforementioned on-line testing in the existing commercialization battery testing, and the charging set that is connected the battery pack two ends also can have influence on testing result.
[utility model content]
But goal of the invention of the present utility model provides a kind of on-line testing, helps people to understand the group connection strap resistance Online Transaction Processing of battery pack connection strap resistance situation immediately, and the ripple of avoiding charging set disturbs and various electromagnetic interference.
The technical scheme that the prior art problem that solves the utility model adopts is: connection strap resistance Online Transaction Processing, it is characterized in that comprising a monitoring main frame, one connects the internal resistance load select a discharge and the connection strap voltage detection unit of each section of respective detection voltage by the monitoring host computer control to battery pack segmentation tap.Fragment size can be set arbitrarily according to the battery joint number of battery pack during use, by monitoring host computer control internal resistance load to the loop generation of each section tap formation and the discharge current of accumulator coupling, the pressure drop that utilizes the connection strap voltage detection unit to catch fast on the connection strap calculates corresponding resistance value then.Can eliminate the influence to test result of the charging set output current that is connected the battery pack two ends to battery pack segmentation direct-current discharge, avoid the ripple of charging set to disturb and other unnecessary interference, the battery pack connection strap resistance value that records accurately and stable.
Internal resistance load described in the utility model is provided with the pin that sets out more than two pairs, and each can form the closed-loop path with battery pack segmentation tap to the pin that sets out, described internal resistance load by monitoring main frame input control select a conducting each to the pin that sets out.Tap is connected with the segmentation battery pack to the pin that sets out to make each, forms a plurality of separate discharge circuits, uses monitoring main frame input control internal resistance load internal switch to switch, and select a conducting each realizes the discharge of every section accumulator to the pin that sets out.
The range of current that monitoring host computer control internal resistance load described in the utility model produces is 30～100A.Through experiment, this range of current is comparatively suitable.
The utility model is connected with battery pack segmentation tap by the internal resistance load, each segmentation battery pack after the tap is selected a discharge, calculate corresponding resistance value after utilizing the connection strap voltage detection unit to gather pressure drop on the connection strap fast, discharge circuit and charging set are independent of each other, realize the online accurate measurement of battery pack connection strap resistance, measurement result is accurate, stable.
