Abstract
The invention relates to a detection device and method for a power battery sampling wire harness. The existing method for detecting the wire harness includes three steps of visual inspection, use of a universal meter and connection battery plate detection. The visual inspection step includes that a worker checks whether a contact pin of a connector on the wire harness is firm in press connection. The step of the use of the universal meter includes that the communication principle of a universal meter is utilized to detect whether the wire harness is correct or not according to drawing paper. The three steps are long in detection time and severely affect working efficiency though correction of wire harness processing can be detected by the three steps. The detection device for the power battery sampling wire harness comprises a battery pack (1) connected with a battery wire (2) connected with an operational amplifier (3), the operational amplifier is connected with a hysteresis comparator (4) connected with a NOR gate (5) and a red light-emitting tube (6) respectively, and the NOR gate is connected with a green light-emitting tube (7). The detection device and method is used for detecting the power battery sampling wire harness.
Description
Technical field:
The present invention relates to a kind of electrokinetic cell sample line Beam Detector and detection method.
Background technology:
The sales volume of electrokinetic cell and battery management system increases, the processing capacity of wire harness also constantly increases, not only require the processing and manufacturing wire harness to realize mechanization gradually, and the equipment that detects wire harness should be arranged, can detect qualified bunch product accurately and rapidly.The method of existing detection wire harness had three steps, and the one, range estimation sees whether the contact pin crimping of connector on the wire harness is firm; The 2nd, use multimeter, utilize the conducting principle of ten thousand tables whether correct according to drawing detection wire harness; The 3rd, connect cell panel and detect, though this three step also can detect the correctness of wire harness processing, detection time is long, has a strong impact on work efficiency.
Summary of the invention:
The purpose of this invention is to provide a kind of electrokinetic cell sample line Beam Detector and detection method.
Above-mentioned purpose realizes by following technical scheme:
A kind of electrokinetic cell sample line Beam Detector, its composition comprises: electric battery, described electric battery and battery line are joined, described battery line is connected with operational amplifier, described operational amplifier is connected with hysteresis loop comparator, described comparer AND, red luminotron respectively connects, and described rejection gate is connected with green luminotron.
Described electrokinetic cell sample line Beam Detector, described operational amplifier is more than or equal to 2; Every group of described comparer and rejection gate are more than or equal to 2; Redness and green luminotron are also greater than 2.
A kind of electrokinetic cell sample line Beam Detector detection method, getting adjacent two cell voltages of series battery sends into, operational amplifier subtracts each other two cell voltages, result after subtracting each other sends into hysteresis loop comparator and compares, comparative result reaches requirement and just signal is sent into rejection gate, removing to drive green LED brightens, if reaching requirement, comparative result just do not brighten with this signal driving red light emitting diodes, therefore, the green LED line of measuring that brightens then is qualified, and red light emitting diodes brightens, and then slotted line is defective.
Beneficial effect:
1. but whether the present invention fast detecting wire harness is qualified, saves for 2/3 time than existing detection wire harness method, improves 3 times work efficiency, and can be used for the on-the-spot accuracy that detects wire harness, simple to operate, convenient and practical, lower cost for material.
2. pure electric automobile or the equipment of other battery operations are in order to reach corresponding power requirement the multiple batteries use that is together in series, for the performance of distinguishing battery and the security of use, we want the change in voltage of real-time monitoring battery, the variation of monitoring cell voltage just need connect sample line at series battery cell positive and negative terminal, the voltage of battery is sent into control and the display unit of battery management system by sample line.If virtual connection or misconnection appear in the battery sampling line in manufacturing process, will directly influence the correct collection of cell voltage, influence the operate as normal of battery management system.
The invention solves the difficult points such as mistake weldering rosin joint of existing detection wire harness, not only increase work efficiency but also improve and detect quality, prevent the error in the artificial judgement.
3. volume of the present invention is little, and little power consumption is easy to operate, and is easy to learn.
