Background technology:
At present, large-scale accumulator testing mainly contains following dual mode:
1) silicon rectifier charging, carbon resistance discharge are characterized in being manual operations, have defectives such as the charging precision is low, adjusting range is narrow, error is big.
2) another kind is to adopt the unit charging/discharging apparatus to discharge and recharge, and its shortcoming is when needing test a plurality of storage batterys, because the volume of large-scale storage battery is big, Heavy Weight, be not easy to carrying, so also needs many special testing equipments, cost height.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the utility model aims to provide and a kind ofly both can independently carry out charge-discharge test to single storage battery, can discharge and recharge the machine of paying provides the parallel heavy-current charge-discharge test for certain storage battery multi-unit parallel heavy-current storage battery charge-discharge control system by parallel connection is a plurality of again.
To achieve these goals, the utility model by the following technical solutions: it comprises a N storage battery and the individual machine of paying that discharges and recharges of N, respectively discharges and recharges and pays the corresponding connection with each storage battery of machine; Each storage battery is communicated with each self-corresponding machine of paying that discharges and recharges by the connection cutter cabinet that is provided with high-current switch separately, is arranged on the status switch that respectively is communicated with in the cutter cabinet and is connected by the self-corresponding machine of paying that discharges and recharges of connection and each; First discharges and recharges with last, and the cutter cabinet in parallel by two series connection is connected between the machine of paying, the middle machine of paying that respectively discharges and recharges is connected between the cutter cabinet in parallel of above-mentioned two series connection by a cutter cabinet in parallel separately, and the status switch that is arranged in each cutter cabinet in parallel is connected by the self-corresponding machine of paying that discharges and recharges of connection and each; The negative pole parallel connection of each storage battery respectively discharges and recharges the machine of paying and is connected with master controller by communication bus.
In technique scheme, N represents storage battery in the whole system, discharges and recharges the quantity of the machine of paying.
Compared with the prior art, the utility model is owing to adopted technique scheme, therefore system not only can be to each storage battery independent test, but also can provide the parallel heavy-current charge-discharge test for certain storage battery by a plurality of machines of paying that discharge and recharge of parallel connection, other equipment that does not insert (storage battery, discharge and recharge the machine of paying) is then unaffected; Have intelligent degree height, low cost and other advantages, and each storage battery all can reach, and system's maximum charges and discharge, electric current value when test.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: storage battery 1 is communicated with cutter cabinet 2 cutter cabinets 3 in parallel and discharges and recharges pair machine 4 master controllers 5 connections 6 high-current switchs 7 status switches 8 communication buses 9
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: N storage battery 1 connects one to one by a connection cutter cabinet 2 and the individual pair machine 4 that discharges and recharges of N separately, is communicated with the status switch 8 that is provided with high-current switch 7 and links with this high-current switch in the cutter cabinet 2; Wherein, high-current switch 7 is paid storage battery 1 machine 4 and is communicated with discharging and recharging, status switch 8 by connection 6 with discharge and recharge a pair machine 4 and be connected.First discharges and recharges input of paying machine 4 and discharges and recharges with last that the cutter cabinet 3 in parallel that is provided with high-current switch 7 by two series connection is connected between the input of pair machine 4, the middle input of paying machine 4 that respectively discharges and recharges is connected between the cutter cabinet 3 in parallel of above-mentioned two series connection by a cutter cabinet 3 in parallel that is provided with high-current switch 7 separately, and the status switches 8 with high-current switch 7 links that are arranged in each cutter cabinet 3 in parallel are connected by the self-corresponding pair machine 4 that discharges and recharges of connection 6 and each; The negative pole parallel connection of each storage battery 1 respectively discharges and recharges pair machine 4 and is connected with master controller 5 by communication bus 9 separately.
Operation principle: during single machine test, the staff is by the keyboard and the large-screen LCD display of master controller, utilize interactive mode to import the required running parameter of test, the test program of master controller sends this running parameter to and discharges and recharges the machine of paying accordingly, this discharges and recharges the machine of paying and enters quasi-operating status through processing with after judging, puts into operation immediately in case receive enabling signal.After equipment brings into operation, discharge and recharge the machine of paying and send control signal to built-in power component, make the test current of storage battery be increased to set point from zero in the short time at the utmost point by built-in D/A converter; Simultaneously, discharge and recharge the machine of paying again by built-in A/D converter from the corresponding current sensor real-time test current value of reading back, and its and set point compared, send revised signal with increase or reduce test current according to comparative result to power component.Like this, by master controller software control, add that the hardware of various electronic components cooperates, make the charging and discharging of accumulator loop form a closed-loop control system, finish various charge-discharge tests tests.When control discharges and recharges, master controller also will be monitored time and accumulator voltage that its inside produces, the intra-record slack byte of setting according to test program is regularly in the memory of data acquiring and recordings such as electric current, voltage, temperature, capacity and time in the master controller, and according to current test program to the test termination condition judge, just stop test immediately automatically as long as reach the condition of end, the data during record end also provide end signal.After the off-test, can get test report (setting data, test data and empirical curve) by printer as required.
During the multi-machine parallel connection test, the staff fills according to storage battery, discharging current calculates the required quantity that discharges and recharges the machine of paying, set the operating current of master controller, each cutter cabinet in parallel closes, the maximum rated operating current that master controller is inquired about the state of cutter cabinet in parallel by connection and discharged and recharged the machine of paying, automatically calculate the current value that respectively discharges and recharges the machine of paying and it is distributed to and respectively discharge and recharge the machine of paying, the close connection cutter cabinet corresponding with the storage battery that needs test and start by master controller and respectively to discharge and recharge the machine of paying filled by the big electric current that respectively discharges and recharges the machine of paying control and finish certain storage battery, discharge test.In the test, the collection data that pair machine that discharges and recharges will be adopted are passed master controller back by communication bus, and whether master controller reaches termination condition according to this data judging test, finishes test by each pair of main controller controls machine.
