Abstract

The invention relates to an intelligent performance analysis and testing bench for batteries of motorized automobiles, which allows the studying and analysis on the charging and discharging characteristics of various batteries in a lab, so as to reduce the studying cost, shorten the studying time, simplify the studying procedures and improve the analysis accuracy. The invention comprises a main system interface module comprising a hi-voltage charging parameter setting module and a hi-voltage charging display module. The hi-voltage charging comprises hi-voltage programmed charging and hi-voltage constant-current charging. The main system interface module additionally comprises a low-voltage charging parameter setting module and a low-voltage charging display module. The low-voltage charging comprises low-voltage programmed charging and low-voltage constant-current charging. The main system interface module additionally comprises a discharging parameter setting module and a discharging display module. The charging comprises programmed discharging and constant-current discharging.

Description

1. Technical field: [0001] The invention relates to a battery test bench, in particular to an electric vehicle battery performance intelligent analysis test bench. 2. Background technology: [0002] The battery is a key component in an electric vehicle, and its performance directly affects the vehicle's dynamic characteristics and mileage. Therefore, it is of great significance to analyze and study the charging and discharging characteristics of batteries for improving the performance of electric vehicles. There are many types of batteries available for electric vehicles, with different charging and discharging characteristics. Usually the characteristics we care about mainly include: charging time, charging mode, charging current, charging voltage, charging temperature rise, discharge time under different discharge currents, discharging temperature rise, cycle times, etc. At present, there are few intelligent detection and test systems for electric vehicle battery perform...
