| Abstract: Power battery, the core component of electric vehicles, directly determines overall performance of electric vehicles. It is very signi cant for battery management to test the performance of battery. A power battery test system is designed based on LabVIEW in this paper. User interface communication were designed. GPIB (General-Purpose Interface Bus) controlled by VISA (Virtual Instrument Software Architecture) was employed to communicate between the software and the instruments, such as DC source, data acquisition unit and electrical load. The result of the experiment shows that the proposed system is capable of testing discharge rate, power-ef cient characteristic and the HPPC (Hybrid Pulse Power Characteristic). |
