一、電(dian)動(dong)車(che)智能充電(dian)器基(ji)本性能及參數：

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(ru)10±0.5h定時。

  當電(dian)流降(jiang)至(zhi)＜1.5A（±0.1A）而大(da)于1.1A（±0.1A）進入40±5min定(ding)時。

  當(dang)電流降至＜1.1A（±0.1A）而大于500mA時取消前一階段的40min定時，進入(ru)新的40±5min定時。

  當電流(liu)降至＜500mA而(er)大于(yu)轉燈(deng)電流(liu)時取(qu)消前一階段的40min定時，進入新(xin)的40±5min定時。

  舉例：48V 10AH 電動車充(chong)電器(qi)為例；

起(qi)充電流＞2.0A（±0.1A）以上(shang)，進(jin)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(ding)時。

  當(dang)電流(liu)降至＜1.5A（±0.1A）而(er)大于1.0A（±0.1A）時(shi)取(qu)消前一階(jie)段的60min定時(shi)，進入新的60±5min定時(shi)。

  當電(dian)(dian)流降(jiang)至＜1.0A（±0.1A）而大于(yu)轉燈電(dian)(dian)流時取消前(qian)一(yi)階段(duan)的60min定時，進(jin)入新(xin)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(liang)導(dao)致溫升過高，變(bian)壓器(qi)溫度達到100℃時(shi)，充電(dian)器(qi)輸出電(dian)流減為1.3A左右（20AH的(de)降至(zhi)1.8A）。

3、反(fan)(fan)接(jie)保護：輸出反(fan)(fan)接(jie)時，充電器無(wu)輸出，充電器燈(deng)(deng)(deng)亮(liang)綠燈(deng)(deng)(deng)10秒鐘(zhong)后指示燈(deng)(deng)(deng)紅綠燈(deng)(deng)(deng)交替閃(shan)爍。

4、空(kong)載(zai)電(dian)壓(ya)(ya):空(kong)載(zai)無輸出電(dian)壓(ya)(ya)。

    二、電動車充電器保護功能檢測方法：

1、  充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)輸出(chu)線接通檢(jian)(jian)測(ce)儀(yi)檢(jian)(jian)測(ce)輸入端，按規定(ding)接通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)燈亮而(er)無(wu)輸出(chu)，同時(shi)(shi)接入一只同極性的(de)(de)普通充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)作為觸發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源，此時(shi)(shi)儀(yi)器(qi)(qi)有顯示(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)正(zheng)常(chang)輸出(chu)。檢(jian)(jian)測(ce)時(shi)(shi)檢(jian)(jian)測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不宜過(guo)低，48V充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)檢(jian)(jian)測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)應(ying)大于40V以防充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)由于負載過(guo)大保護而(er)中斷輸出(chu)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)逐(zhu)漸(jian)降低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)逐(zhu)漸(jian)升高直(zhi)至轉(zhuan)(zhuan)態電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)轉(zhuan)(zhuan)態時(shi)(shi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)為轉(zhuan)(zhuan)態電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，轉(zhuan)(zhuan)態前的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為最高電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，轉(zhuan)(zhuan)態后的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為轉(zhuan)(zhuan)態電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)檢(jian)(jian)測(ce)時(shi)(shi)應(ying)避免(mian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)過(guo)低以防輸出(chu)中斷。
