【摘要】：當(dāng)前大部分充電機(jī)硬件電路設(shè)計(jì)過(guò)于簡(jiǎn)單,通常是恒壓恒流充電,同時(shí)充電控制過(guò)程只適于某一種蓄電池,無(wú)法有效控制充電過(guò)程,在很大程度上會(huì)導(dǎo)致電池欠充或過(guò)充,減少蓄電池使用壽命。為此,設(shè)計(jì)一種新的電動(dòng)汽車(chē)多段式智能自動(dòng)化充電機(jī)。硬件設(shè)計(jì)中,介紹了主電路、采集電路和控制電路的設(shè)計(jì)過(guò)程。軟件設(shè)計(jì)中,將整流電路和蓄電池共同看作被控對(duì)象,將充電機(jī)的輸出和一個(gè)小電感串聯(lián)在一起,給出被控對(duì)象數(shù)學(xué)模型,將其看作傳遞函數(shù),通過(guò)PID算法對(duì)充電機(jī)進(jìn)行充電控制。實(shí)驗(yàn)結(jié)果表明,所設(shè)計(jì)充電機(jī)穩(wěn)壓穩(wěn)流精度高、并聯(lián)均流不平衡度低、發(fā)熱狀態(tài)可達(dá)到允許溫升要求,且充電控制性能高。
[Abstract]:Most of the current hardware circuit design is too simple, usually constant voltage and constant current charging, while charging control process is only suitable for a certain battery, can not effectively control the charging process. To a great extent, the battery will be undercharged or overcharged, and the service life of battery will be reduced. Therefore, a new multi-segment intelligent automatic charger for electric vehicle is designed. In the hardware design, the main circuit is introduced. Acquisition circuit and control circuit design process. In the software design, the rectifier circuit and the battery are regarded as the controlled object together, the output of the charger and a small inductor are connected in series, and the mathematical model of the controlled object is given. It is regarded as a transfer function, and the charging control is carried out by PID algorithm. The experimental results show that the designed charger has high precision of steady voltage and steady current, and low imbalance of parallel current sharing. The heating state can reach the allowable temperature rise requirement, and the charge control performance is high.
