一、電(dian)動車智能充電(dian)器基本性能及參(can)數：

1、定時功能：舉例：48V 10AH 電動車充電器為例；

  起充電(dian)流＞1.5A（±0.1A）以上，進入10±0.5h定時。

  當電流降(jiang)至＜1.5A（±0.1A）而(er)大于1.1A（±0.1A）進入40±5min定時。

  當電(dian)流降至＜1.1A（±0.1A）而(er)大于500mA時取(qu)消前(qian)一階段的(de)40min定時，進入(ru)新的(de)40±5min定時。

  當電流(liu)降至＜500mA而大于轉燈電流(liu)時(shi)取(qu)消前一階(jie)段的40min定時(shi)，進入新的40±5min定時(shi)。

  舉例：48V 10AH 電動車充(chong)電器為(wei)例；

起充(chong)電流＞2.0A（±0.1A）以上，進入10±0.5h定時。

  當電流降至＜2.0A（±0.1A）而大(da)于(yu)1.5A（±0.1A）進入60±5min定時。

  當電流(liu)降至＜1.5A（±0.1A）而大于1.0A（±0.1A）時取消前一階段的(de)60min定(ding)時，進(jin)入新(xin)的(de)60±5min定(ding)時。

  當電流(liu)降至(zhi)＜1.0A（±0.1A）而大于轉燈電流(liu)時取(qu)消(xiao)前一階段(duan)的60min定時，進入新的60±5min定時。

2、過熱保護功能

  由于外界溫度過高或者充電器充電(dian)環境通風不良導致(zhi)溫升(sheng)過高，變壓器溫度(du)達到100℃時，充電(dian)器輸出(chu)電(dian)流(liu)減為1.3A左右(you)（20AH的(de)降至1.8A）。

3、反(fan)接保護：輸(shu)出反(fan)接時，充(chong)電(dian)器無輸(shu)出，充(chong)電(dian)器燈亮綠燈10秒鐘后指示燈紅(hong)綠燈交替閃爍。

4、空載電壓:空載無輸出電壓。

    二、電動車充電器保護功能檢測方法：

1、  充電(dian)(dian)(dian)(dian)器(qi)(qi)輸(shu)出線接通(tong)檢(jian)測(ce)(ce)(ce)儀(yi)檢(jian)測(ce)(ce)(ce)輸(shu)入(ru)端(duan)，按規定接通(tong)電(dian)(dian)(dian)(dian)源充電(dian)(dian)(dian)(dian)器(qi)(qi)燈亮而無(wu)輸(shu)出，同時(shi)接入(ru)一只同極性的(de)普通(tong)充電(dian)(dian)(dian)(dian)器(qi)(qi)作為觸發電(dian)(dian)(dian)(dian)源，此時(shi)儀(yi)器(qi)(qi)有顯示電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)及(ji)電(dian)(dian)(dian)(dian)流，充電(dian)(dian)(dian)(dian)器(qi)(qi)正常輸(shu)出。檢(jian)測(ce)(ce)(ce)時(shi)檢(jian)測(ce)(ce)(ce)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)不宜過(guo)低，48V充電(dian)(dian)(dian)(dian)器(qi)(qi)檢(jian)測(ce)(ce)(ce)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)應(ying)大于40V以防充電(dian)(dian)(dian)(dian)器(qi)(qi)由(you)于負載過(guo)大保護(hu)而中斷(duan)(duan)輸(shu)出，電(dian)(dian)(dian)(dian)流逐(zhu)漸(jian)降低電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)逐(zhu)漸(jian)升高直至轉態電(dian)(dian)(dian)(dian)流轉態時(shi)的(de)電(dian)(dian)(dian)(dian)流為轉態電(dian)(dian)(dian)(dian)流，轉態前(qian)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)為最高電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，轉態后的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)為轉態電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，低電(dian)(dian)(dian)(dian)流檢(jian)測(ce)(ce)(ce)時(shi)應(ying)避免電(dian)(dian)(dian)(dian)流過(guo)低以防輸(shu)出中斷(duan)(duan)。

2、10小時定時功能檢測

  將充電(dian)(dian)器(qi)直接進入充電(dian)(dian)電(dian)(dian)流大(da)于1.5A（20AH的為(wei)2.0A）并保持大(da)于1.5A（20AH的為(wei)2.0A）充電(dian)(dian)狀(zhuang)態下,10小(xiao)時(shi)(shi)后充電(dian)(dian)器(qi)自動轉換(huan)（參(can)考方法(fa)：先將充電(dian)(dian)器(qi)調至(zhi)1.5A±0.1A電(dian)(dian)流以上后切斷電(dian)(dian)源(yuan)(yuan)，再重新接通電(dian)(dian)源(yuan)(yuan)，同(tong)時(shi)(shi)接入一只同(tong)極性(xing)的普通充電(dian)(dian)器(qi)作為(wei)觸發電(dian)(dian)源(yuan)(yuan)，讓充電(dian)(dian)器(qi)觸發進入10小(xiao)時(shi)(shi)定時(shi)(shi)狀(zhuang)態，不可由低電(dian)(dian)流段(duan)調至(zhi)大(da)電(dian)(dian)流段(duan)測試(shi)。）

將(jiang)(jiang)充(chong)電(dian)(dian)器直接(jie)進入(ru)小于1.5A（20AH的(de)(de)為2.0A）并(bing)保(bao)持大(da)于1.1A（20AH的(de)(de)為1.5A）充(chong)電(dian)(dian)狀態下(xia),40min（20AH的(de)(de)為60min）定時啟(qi)動(dong)（參考方法：先(xian)將(jiang)(jiang)充(chong)電(dian)(dian)器電(dian)(dian)流(liu)調至(zhi)1.5A～0.1A后(hou)切(qie)斷充(chong)電(dian)(dian)電(dian)(dian)源(yuan)，再重(zhong)新接(jie)通電(dian)(dian)源(yuan)，同時接(jie)入(ru)一只同極性的(de)(de)普通充(chong)電(dian)(dian)器作為觸發(fa)電(dian)(dian)源(yuan)讓(rang)充(chong)電(dian)(dian)器觸發(fa)進入(ru)該40分鐘(zhong)（20AH的(de)(de)為60min）定時狀態，不(bu)可由低電(dian)(dian)流(liu)段調至(zhi)大(da)電(dian)(dian)流(liu)段測試。）

將充電(dian)(dian)器直接(jie)進入小(xiao)于1.1A（20AH的(de)(de)為(wei)(wei)1.5A）并保(bao)持大于500mA（20AH的(de)(de)為(wei)(wei)1.0A）充電(dian)(dian)狀(zhuang)態(tai)下,該40min定時(shi)(shi)啟動（參考方法：先將充電(dian)(dian)器電(dian)(dian)流(liu)調(diao)至1.0A～0.1A后切斷充電(dian)(dian)電(dian)(dian)源，再重新接(jie)通電(dian)(dian)源，同(tong)時(shi)(shi)接(jie)入一只同(tong)極性的(de)(de)普通充電(dian)(dian)器作(zuo)為(wei)(wei)觸發(fa)電(dian)(dian)源讓充電(dian)(dian)器觸發(fa)進入該40分鐘(zhong)（120AH的(de)(de)為(wei)(wei)60min）定時(shi)(shi)狀(zhuang)態(tai)，不(bu)可由低電(dian)(dian)流(liu)段(duan)(duan)調(diao)至大電(dian)(dian)流(liu)段(duan)(duan)測試(shi)。）

將充電器直接進入電流為500mA（20AH的為1.0A）以下并保持大于轉換點充電狀態下,該40min（20AH的為60min）定時啟動（參考方法：先將充電器電流調至500mA～轉態電流后切斷充電電源，再重新接通電源，同時接入一只同極性的普通充電器作(zuo)為觸(chu)發電源(yuan)讓充電器(qi)觸(chu)發進入該40分(fen)鐘定時(shi)狀(zhuang)態。）
