Description
The present invention relates to a kind of charging-discharge tester system, be meant the charge-discharge test that is applied to the notebook computer battery especially, and can write down the test macro of the test data of charge and discharge process automatically.
Battery has been that the standard of notebook computer one of is equipped with, and the quality of battery more can influence the power supply supply of computer, so battery precedingly must do detailed test what dispatch from the factory, just can guarantee the quality of using.
Traditional charging-discharge tester system as shown in Figure 1, traditional test mode is that battery to be tested is installed in the notebook computer 1, come record test data via temperature/voltage register 2, connection by battery voltage signal line 34, battery temperature signal wire 35 and battery ground wire 38 between the two, it is as follows that it discharges and recharges step normally:
1. the power supply with notebook computer connects, and uncharged battery is charged, and opens register simultaneously, so that the voltage of battery, electric current and temperature variation are shut down when charging in monitoring.
2. at set intervals, the variation of numerical value on the inspection record paper and the battery status cresset on the notebook computer, with the electric power of judging battery whether be full of or its state whether normal.
3. when the electric power of battery to be determined is full of, notebook computer start and executive routine are removed to read the status data of inside battery, with artificial mode these records of values are got off simultaneously.
4. execution discharge procedures is pulled out the power supply of notebook computer, simultaneously the state during register opening entry battery discharge.
5. at set intervals, check that whether notebook computer shuts down because of consumable power source.
6. after determining that battery discharge finishes, plug in, with the notebook computer start, executive routine reads discharge time again, this moment because of battery again by the electric weight that charges into a little, so after must being discharged again, carry out the circulation that the next one discharges and recharges again.
By top step narration as can be known, the charge-discharge test of battery is the test event of suitable time-consuming and manpower, not only the time of charge-discharge test is long, and need very numerous and diverse manually-operated (for example: executive routine) with record (for example: the correlation values that discharges and recharges), the result who adds test must be via the numerical value that manually removes comparative voltage register and system log (SYSLOG), therefore, whole test process is quite tediously long trouble.
If need other charge and discharge modes of test, for example partly fill partly and put, the step of test just becomes more numerous and diverse, even what is difficult to carry out, the user can't exhaust battery electric quantity just at every turn and be charged after all, but with regard to product test, but is the step that must carry out, for the tester, be quite heavy numerous and diverse work and be difficult to carry out.
In addition, very long by the time consumption that what discharges and recharges, if the time After Hours can not be made full use of, it is very long that the time of whole charging and discharging test certainly will be drawn, even what has influence on the time cost that company pays.
Fundamental purpose of the present invention provides a kind of charging-discharge tester system at what, is meant the charge-discharge test of using what notebook computer battery especially, and can write down the test macro of the test data of charge and discharge process automatically.
