OBC(車(che)載(zai)充電(dian)(dian)機)是(shi)電(dian)(dian)動汽車(che)實現交流(liu)充電(dian)(dian)的核心(xin)設備，其與(yu)充電(dian)(dian)樁的兼(jian)容性直接影響電(dian)(dian)動汽車(che)的充電(dian)(dian)體驗(yan)和使用便利性。OBC 與(yu)充電(dian)(dian)樁兼(jian)容性測試(shi)是(shi)為了確保(bao)兩者(zhe)在通信協議、電(dian)(dian)氣參數(shu)、安(an)全保(bao)護等方面(mian)相互匹配，能夠穩定、高(gao)效地完成(cheng)充電(dian)(dian)過程。
兼(jian)容性測試(shi)涵蓋多個方面。在(zai) 通信協議測試(shi) 中，需(xu)驗證 OBC 與充電(dian)樁(zhuang)之(zhi)間(jian)(jian)能否(fou)正(zheng)確(que)(que)解析和執行充電(dian)通信協議，如國標 GB/T 18487.1 規(gui)定的(de)(de)充電(dian)通信標準(zhun)。測試(shi)過程中，模擬不同的(de)(de)通信場景(jing)，包括正(zheng)常充電(dian)流程的(de)(de)通信交互、充電(dian)過程中的(de)(de)狀態變更通知(zhi)、異常情況的(de)(de)信息交互等，檢查兩者之(zhi)間(jian)(jian)的(de)(de)通信是否(fou)順暢，數(shu)據(ju)傳輸(shu)是否(fou)準(zhun)確(que)(que)無誤。例如，測試(shi)充電(dian)樁(zhuang)發送的(de)(de)充電(dian)參數(shu)指令，OBC 能否(fou)正(zheng)確(que)(que)接收并(bing)執行;OBC 反饋的(de)(de)充電(dian)狀態信息，充電(dian)樁(zhuang)是否(fou)能夠(gou)準(zhun)確(que)(que)識別和顯示(shi)。
電(dian)(dian)(dian)(dian)氣參(can)數兼容(rong)性(xing)測(ce)(ce)(ce)試 主要包(bao)括電(dian)(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)(dian)流匹配(pei)性(xing)測(ce)(ce)(ce)試。測(ce)(ce)(ce)試充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)輸(shu)出的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)(dian)流范圍是(shi)否(fou)在 OBC 的(de)(de)額定(ding)工(gong)作(zuo)范圍內，以及兩者在功率傳輸(shu)過(guo)(guo)程(cheng)中的(de)(de)穩(wen)定(ding)性(xing)。通過(guo)(guo)調節充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)的(de)(de)輸(shu)出參(can)數，模擬(ni)不同的(de)(de)電(dian)(dian)(dian)(dian)網(wang)條件和充(chong)電(dian)(dian)(dian)(dian)需求，監測(ce)(ce)(ce) OBC 的(de)(de)輸(shu)入電(dian)(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)(dian)流、功率因(yin)數等(deng)參(can)數，評估其對不同電(dian)(dian)(dian)(dian)氣參(can)數的(de)(de)適(shi)應能(neng)力。同時，測(ce)(ce)(ce)試在充(chong)電(dian)(dian)(dian)(dian)過(guo)(guo)程(cheng)中，當電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)壓(ya)(ya)波(bo)動或負(fu)載變化(hua)時，OBC 與充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)能(neng)否(fou)協同工(gong)作(zuo)，保持穩(wen)定(ding)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)性(xing)能(neng)。
安(an)(an)全(quan)保護兼(jian)容(rong)(rong)性測試(shi) 是(shi)確保充(chong)電(dian)(dian)過程安(an)(an)全(quan)的(de)重要環節。測試(shi)內容(rong)(rong)包括過壓(ya)、欠(qian)壓(ya)、過流、漏電(dian)(dian)等(deng)(deng)保護功能的(de)協同工作情況。例(li)如，當充(chong)電(dian)(dian)樁(zhuang)檢測到漏電(dian)(dian)故(gu)障時，能否(fou)及時向(xiang) OBC 發送停止充(chong)電(dian)(dian)指令，OBC 是(shi)否(fou)能夠(gou)(gou)迅(xun)速響(xiang)應并切斷(duan)充(chong)電(dian)(dian)回路;在過壓(ya)、欠(qian)壓(ya)等(deng)(deng)異常情況下(xia)，兩者的(de)保護機制(zhi)是(shi)否(fou)能夠(gou)(gou)有效配合(he)，避(bi)免設備損壞和(he)(he)安(an)(an)全(quan)事故(gu)的(de)發生。此外，還需測試(shi)充(chong)電(dian)(dian)連(lian)接控(kong)制(zhi)導引電(dian)(dian)路的(de)兼(jian)容(rong)(rong)性，確保充(chong)電(dian)(dian)插頭(tou)正確連(lian)接和(he)(he)斷(duan)開時，OBC 與充(chong)電(dian)(dian)樁(zhuang)能夠(gou)(gou)進行安(an)(an)全(quan)的(de)交互和(he)(he)控(kong)制(zhi)。
