Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, makes required in being described below to embodiment Accompanying drawing is briefly described.
Fig. 1 is the logic control chart of the intelligent stand test platform of battery performance proposed by the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described.
Embodiment:
Shown in Fig. 1, a kind of intelligent stand test platform of battery performance, the test platform by industrial computer, climatic chamber, Electrokinetic cell is performance test bed and battery parameter management system is constituted, and is communicated using TCP/IP communication modes.Industry is calculated Machine is provided with magnetic disk storage, for receiving, the battery parameter that storage control module is transmitted.Climatic chamber can ensure in electricity External temperature environment when simulated battery is normally used in the test process of pond so that environment temperature is changed by intended flow.Power Battery performance test platform can apply current-vs-time damping to tested battery, can simulate the battery charge and discharge in real road operating mode Electric current, tests battery performance.Battery parameter management system includes main controller module, current measurement module, voltage measurement mould Block and temperature-measuring module, are communicated using CAN communication modes.Main controller module be used for receive or on conduct electricity The battery parameter that stream, voltage and temperature-measuring module are transmitted.Current measurement module measurement collection cell electric current, measured electricity The parameter such as pond group total current and total voltage.Voltage, the voltage of temperature-measuring module collection cell, temperature, and it is total by CAN Line obtains the corresponding current parameters of cell to calculate internal resistance of single cell.
Implementation principle:Industrial computer sends beginning test signal, when climatic chamber and battery performance test platform pass through ICP/IP protocol is received after beginning test signal, according to predetermined temperature and real road operating mode to being measured battery module Enter trip temperature and real road operating mode is set, then current measurement module, voltage measurement module and temperature-measuring module point Not by digital-type intelligent current sensor, digital-type intelligent voltage sensor and digital-type intelligent temperature sensor simultaneously to electricity Electric current, voltage and the temperature of pond group are detected, and detection to data signal is passed into master controller mould by CAN Block, main controller module according to the signal of receiving carry out computing, compare, analyze, the process such as convert, by the performance of measured battery pack Parameter is transferred to industrial computer by ICP/IP protocol and shows and store, the cyclicity thus, it is possible to judge measured battery pack Can, it is that battery model checking and battery status parameter Research on Evaluation Method provide reliable data and supported.
In addition, the platform can also judge whether power battery pack circuit occurs event according to measured battery parameter Barrier, possesses power battery pack insulaion resistance detection function.Accordingly, corresponding cell branch current can also be obtained, is calculated The internal resistance of cell, possesses battery pack and overcharges, crosses and put fault alarm function.
A variety of modifications to these embodiments will be apparent for those skilled in the art, herein Defined General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.
