    摘要:

    為進(jìn)一步提高電動(dòng)汽車的能量利用效率以改善其續(xù)駛里程，開發(fā)了一套電動(dòng)汽車制動(dòng)能量回收系統(tǒng)。系統(tǒng)結(jié)構(gòu)簡單，可靠性高，并具有機(jī)械制動(dòng)備份功能。同時(shí)，考慮到電動(dòng)汽車電動(dòng)機(jī)和電池性能參數(shù)，開發(fā)了高效的再生制動(dòng)控制策略，算法具有較強(qiáng)的移植性。采用硬件在環(huán)的方式對系統(tǒng)的控制效果和制動(dòng)能量回收效率進(jìn)行了仿真測試。結(jié)果表明，再生制動(dòng)力和摩擦制動(dòng)力可以很好地協(xié)調(diào)運(yùn)作，同時(shí)有效地回收制動(dòng)能量。最后，在燃料電池汽車上進(jìn)行轉(zhuǎn)鼓實(shí)驗(yàn)，很好地完成了Japan-1015循環(huán)工況，能量回收效率高達(dá)59.15%。

    Abstract:

    In order to further improve the energy efficiency of electric vehicles, thus to improve the driving range economy, a braking energy recovery system for electric vehicles with simple structure, high reliability and fail-safe function was developed. Meanwhile, considering performance parameters of motor and battery, the efficient regenerative braking control strategy with strong portability was developed. Based on the proposed system and control strategy, hardware-in-loop tests were accomplished. Test results showed that friction braking force and regenerative braking force could be well integrated and braking energy recovery efficiency was high. Finally, experimental data of a FCV on CYC Japan-1015 proved the performance and feasibility of the proposed system. Braking energy recovery efficiency reached to 59.15%.
