一、電(dian)動車智能(neng)(neng)充電(dian)器(qi)基本性能(neng)(neng)及參數：

1、定時功能：舉例：48V 10AH 電動車充電器為例；

  起充電流＞1.5A（±0.1A）以上，進入10±0.5h定時。

  當電流降至(zhi)＜1.5A（±0.1A）而大于1.1A（±0.1A）進入40±5min定(ding)時。

  當電流降至＜1.1A（±0.1A）而大于500mA時(shi)取消前一階段(duan)的40min定時(shi)，進入新的40±5min定時(shi)。

  當電(dian)流(liu)降(jiang)至＜500mA而大于(yu)轉燈電(dian)流(liu)時(shi)取(qu)消前一階(jie)段(duan)的(de)40min定(ding)時(shi)，進入(ru)新的(de)40±5min定(ding)時(shi)。

  舉例：48V 10AH 電動車(che)充電器為(wei)例；

起充電流＞2.0A（±0.1A）以上，進入10±0.5h定時。

  當電(dian)流降至＜2.0A（±0.1A）而大于1.5A（±0.1A）進入(ru)60±5min定時(shi)。

  當(dang)電流降至＜1.5A（±0.1A）而(er)大于1.0A（±0.1A）時取消前(qian)一階段的60min定時，進入新的60±5min定時。

  當電(dian)流(liu)降至(zhi)＜1.0A（±0.1A）而大于轉燈電(dian)流(liu)時取消前一階(jie)段的60min定時，進入(ru)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環境通風不(bu)良(liang)導致溫升過高，變壓器溫度(du)達到100℃時，充電器輸出電流減為1.3A左右（20AH的降(jiang)至(zhi)1.8A）。

3、反(fan)(fan)接保護：輸出反(fan)(fan)接時，充電器無輸出，充電器燈(deng)亮綠(lv)(lv)燈(deng)10秒鐘后指示燈(deng)紅綠(lv)(lv)燈(deng)交替閃(shan)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(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)輸(shu)(shu)出(chu)(chu)線接通(tong)(tong)檢(jian)測(ce)(ce)儀檢(jian)測(ce)(ce)輸(shu)(shu)入(ru)(ru)端(duan)，按規定(ding)接通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)源充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)燈亮而無輸(shu)(shu)出(chu)(chu)，同(tong)時(shi)接入(ru)(ru)一只同(tong)極性(xing)的(de)普(pu)通(tong)(tong)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)作(zuo)為(wei)觸發電(dian)(dian)(dian)(dian)(dian)源，此(ci)時(shi)儀器(qi)有顯示電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)及電(dian)(dian)(dian)(dian)(dian)流(liu)，充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)正常輸(shu)(shu)出(chu)(chu)。檢(jian)測(ce)(ce)時(shi)檢(jian)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不宜過低，48V充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)檢(jian)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)應大(da)于40V以防充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)由于負載過大(da)保護而中斷輸(shu)(shu)出(chu)(chu)，電(dian)(dian)(dian)(dian)(dian)流(liu)逐漸降低電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)逐漸升高直至轉(zhuan)態(tai)電(dian)(dian)(dian)(dian)(dian)流(liu)轉(zhuan)態(tai)時(shi)的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)為(wei)轉(zhuan)態(tai)電(dian)(dian)(dian)(dian)(dian)流(liu)，轉(zhuan)態(tai)前的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)最高電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，轉(zhuan)態(tai)后(hou)的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)轉(zhuan)態(tai)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，低電(dian)(dian)(dian)(dian)(dian)流(liu)檢(jian)測(ce)(ce)時(shi)應避免電(dian)(dian)(dian)(dian)(dian)流(liu)過低以防輸(shu)(shu)出(chu)(chu)中斷。

2、10小時定(ding)時功能檢測
