充電系統(tǒng)控制分析國(guó)家標(biāo)準(zhǔn)化管理會(huì)在2015年12月發(fā)布了GB/T18487.1-2015電動(dòng)汽車傳導(dǎo)充電系統(tǒng)第1部分：通用要求，定義了充電接口原理和時(shí)序，于2017年10月發(fā)布了GB/T34657.2-2017電動(dòng)汽車傳導(dǎo)充電互操作性測(cè)試規(guī)范第2部分：車輛。國(guó)標(biāo)建議的控制引電電路原理如圖2所示，解決新能源汽車和充電樁的充電兼容性，但是整車內(nèi)部實(shí)現(xiàn)的方案卻各有不同。檢測(cè)點(diǎn)2、3的檢測(cè)電路有放在充電機(jī)、BMS、整車控制器內(nèi)部，這就要求OBC的零件生產(chǎn)企業(yè)要設(shè)計(jì)多種電路來匹配不同整車企業(yè)的需求，軟件策略也同樣需要調(diào)整，從行業(yè)高度分析，不利于降低開發(fā)及單件成本。調(diào)研分析小結(jié)新能源汽車的中心零件可分為三部分：動(dòng)力電池，電驅(qū)（電機(jī)控制器，電機(jī)，減速器），小三電（PDU+DC+OBC）；原因每一部分的技術(shù)與其它部分相對(duì)**，且有整合提升空間。不同車型小三電的組合方式不同，PDU原理不同，連接器不同，功率需求不同，控制引導(dǎo)電路實(shí)現(xiàn)方式不同，導(dǎo)致不能通過規(guī)模化降低成本。因此，如何把小三電有機(jī)分解易于規(guī)?；切袠I(yè)研究的重點(diǎn)和難點(diǎn)。</p><p
