H系列回饋(kui)式(shi)(shi)充放(fang)電(dian)(dian)設備(bei)可針對大(da)型(xing)倉庫或者整(zheng)車廠(chang)的(de)整(zheng)套高(gao)壓電(dian)(dian)池系統做(zuo)充放(fang)電(dian)(dian)維護，用(yong)于寬電(dian)(dian)壓范圍、功率(lv)大(da)的(de)鋰電(dian)(dian)池包，進行集中(zhong)式(shi)(shi)維護保養(yang)，設備(bei)采用(yong)回饋(kui)型(xing)的(de)放(fang)電(dian)(dian)方式(shi)(shi)，現場不產生(sheng)新熱源，測(ce)試高(gao)效節能又(you)安全。
主要應用場景：
售后、4S店、儲運中(zhong)的(de)鋰電池包維護保養。
功(gong)能特點(dian)
● 能(neng)量回饋：整個系(xi)統能(neng)量具有雙向流動性，自動調節能(neng)量方(fang)向，充放電(dian)(dian)(dian)(dian)(dian)維護(hu)時，電(dian)(dian)(dian)(dian)(dian)池包與三(san)相電(dian)(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)(dian)能(neng)回饋，直流母線(xian)效率≥93%，節約大(da)量耗電(dian)(dian)(dian)(dian)(dian)開(kai)支(zhi)和耗熱型維護(hu)所產生的空調電(dian)(dian)(dian)(dian)(dian)費開(kai)支(zhi)
● 大功率隔(ge)離變壓器，整(zheng)套系(xi)統與電(dian)網隔(ge)離，輸出電(dian)流轉換快、電(dian)流無超調(diao)現象，系(xi)統運行(xing)可(ke)靠，穩定
● DC/AC模塊采用空(kong)間矢(shi)量調(diao)制(zhi)技(ji)術，數字(zi)化控制(zhi)，使得電(dian)壓利(li)用率(lv)高(gao)，電(dian)流諧波分(fen)流更小
DC/DC模(mo)塊采用(yong)先進(jin)的PID調節技術(shu)，多重(zhong)保護機制(zhi)，保證設備運(yun)行穩定性
● 能夠(gou)與外(wai)部工裝(zhuang)做通訊，接收外(wai)部信(xin)息(xi)以及控制指(zhi)令(ling)
● CCCV 充電(dian)(dian)：充電(dian)(dian)過程無任何(he)的電(dian)(dian)壓電(dian)(dian)流沖(chong)(chong)擊(ji)，有效防止電(dian)(dian)池因尖峰(feng)電(dian)(dian)流出現(xian)熱量集中導致極(ji)耳脫粉或(huo)微(wei)短路產生孤島(dao)效應或(huo)過沖(chong)(chong)現(xian)象(xiang)引起 PCB 的保護動(dong)(dong)作和(he)二次保護動(dong)(dong)作。
● 采用高(gao)精度(du)，高(gao)動(dong)態范圍(wei) ADC/DAC 單元，電壓(ya)采樣精度(du)高(gao)，長期(qi)穩定性好
● DCIR 直流負載(zai)(zai)阻(zu)抗測試(shi)：實時(shi)偵測電池充帶載(zai)(zai)/驟(zou)卸(xie)載(zai)(zai)時(shi)ms級內(nei)負載(zai)(zai)阻(zu)抗，識(shi)別 DCIR 不(bu)穩定電池
● 電壓(ya)鉗位(wei)：充電過程中在電池保護(hu)動作或設備異(yi)常時，電壓(ya)可鉗位(wei)在設定電壓(ya)，防止保護(hu)板損壞
● ECD&EVD 保(bao)護：能避免與挑(tiao)選出電池(chi)(chi)因不合格條件下(xia)造成主動(dong)保(bao)護并提前停(ting)止充電或(huo)放電的(de)電池(chi)(chi)
