目前,隨著環(huán)境污染、石油資源不可再生等問題日趨嚴(yán)重,環(huán)境污染和能源局限已成了世界范圍內(nèi)的以內(nèi)燃機(jī)為動(dòng)力的燃油汽車所面臨的兩大難題。2015年2月,科技部發(fā)布《國(guó)家重點(diǎn)研發(fā)計(jì)劃新能源汽車重點(diǎn)專項(xiàng)實(shí)施方案(征求意見稿)》,旨在落實(shí)《節(jié)能與新能源汽車產(chǎn)業(yè)發(fā)展規(guī)劃(2012-2020年)》,并強(qiáng)調(diào)實(shí)施新能源汽車“純電驅(qū)動(dòng)”技術(shù)轉(zhuǎn)型戰(zhàn)略,完善電動(dòng)汽車“三縱三橫”技術(shù)體系和新能源汽車研發(fā)體系等內(nèi)容。發(fā)展新能源汽車包括混合動(dòng)力汽車(H=EV)、純電動(dòng)汽車(PEV)以及燃料電池汽車(FCEV)是實(shí)現(xiàn)我國(guó)能源安全和環(huán)境保護(hù)以及中國(guó)汽車工業(yè)健康可持續(xù)發(fā)展的必然趨勢(shì)。純電動(dòng)汽車以車載二次電源作為儲(chǔ)能方式,以電動(dòng)機(jī)為動(dòng)力裝置驅(qū)動(dòng)車輛行駛,相比混合動(dòng)力汽車而言,具有零排放、低噪聲且結(jié)構(gòu)簡(jiǎn)單等特點(diǎn),而相比燃料電池則在當(dāng)前更具產(chǎn)業(yè)化的基礎(chǔ),因此而受到了世界各國(guó)政府及汽車企業(yè)的廣泛關(guān)注。
本書從新能源汽車專業(yè)英語(yǔ)的角度出發(fā),將新能源汽車技術(shù)內(nèi)容劃分為電池、電機(jī)、電控三部分核心技術(shù),另外增加新能源汽車發(fā)展歷史、現(xiàn)狀,以及相關(guān)的國(guó)外產(chǎn)業(yè)政策等內(nèi)容。本書編寫過程中,結(jié)合目前很多國(guó)外新能源汽車技術(shù),將其系統(tǒng)化后,結(jié)合國(guó)內(nèi)新能源汽車專業(yè)培養(yǎng)學(xué)生需要,以及行業(yè)、企業(yè)崗位需求,以項(xiàng)目化教學(xué)為主線,設(shè)計(jì)本書的內(nèi)容。
全書由衢州職業(yè)技術(shù)學(xué)院方曉汾老師編著,項(xiàng)目一、項(xiàng)目二、項(xiàng)目三由東北石油大學(xué)張勇老師和惠州經(jīng)濟(jì)職業(yè)技術(shù)學(xué)院鐘文浩老師審稿,項(xiàng)目四、項(xiàng)目五由河北工業(yè)大學(xué)武春龍老師審稿,項(xiàng)目六、項(xiàng)目七由江蘇安全技術(shù)職業(yè)學(xué)院溫俊芳老師審稿,南京理工大學(xué)方斌教授主審。
感謝共同參與工作的衢州求是科技聯(lián)合會(huì)各位同仁,感謝浙江大學(xué)朱紹鵬副教授、美國(guó)ASE(Automotive Service Excellence)高級(jí)技師Paul Polzer提出的寶貴修改意見。感謝校級(jí)課改項(xiàng)目(NO.KGXM201609)支持。
本書在編寫過程中,引用了純電動(dòng)汽車標(biāo)準(zhǔn)、網(wǎng)絡(luò)資源以及圖片,特向其作者表示感謝。
