一、電動車智能(neng)充電器基本性能(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(liu)＞1.5A（±0.1A）以上，進入10±0.5h定時。

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

  當電流降至(zhi)＜1.1A（±0.1A）而(er)大于500mA時取消前一階段的(de)40min定時，進入新的(de)40±5min定時。

  當(dang)電流降至＜500mA而(er)大于轉燈電流時取消前一階段的40min定(ding)時，進(jin)入新的40±5min定(ding)時。

  舉例：48V 10AH 電(dian)動(dong)車充電(dian)器為例；

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

  當電流降至＜2.0A（±0.1A）而大于1.5A（±0.1A）進入60±5min定(ding)時。

  當(dang)電流降至＜1.5A（±0.1A）而大于1.0A（±0.1A）時(shi)(shi)取消(xiao)前(qian)一階段的60min定時(shi)(shi)，進入新的60±5min定時(shi)(shi)。

  當電流降至＜1.0A（±0.1A）而大于轉燈電流時(shi)取消前一階段的(de)60min定(ding)時(shi)，進入新的(de)60±5min定(ding)時(shi)。

2、過熱保護功能

  由于外界溫度過高或者充電器充電(dian)(dian)環(huan)境(jing)通風不良(liang)導致溫升過高，變壓器溫度(du)達到100℃時，充電(dian)(dian)器輸出(chu)電(dian)(dian)流減為(wei)1.3A左右（20AH的降至(zhi)1.8A）。

3、反接保護：輸(shu)出反接時，充電(dian)器無輸(shu)出，充電(dian)器燈(deng)亮綠燈(deng)10秒鐘后指示燈(deng)紅綠燈(deng)交(jiao)替閃爍。

4、空載電壓(ya):空載無輸出(chu)電壓(ya)。

    二、電動車充電器保護功能檢測方法：

1、  充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)輸出(chu)(chu)線(xian)接(jie)通(tong)檢測(ce)儀(yi)檢測(ce)輸入端，按(an)規定接(jie)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)燈亮(liang)而無輸出(chu)(chu)，同時接(jie)入一只(zhi)同極(ji)性的(de)(de)普通(tong)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)作為(wei)觸(chu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源，此(ci)時儀(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，充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)正常輸出(chu)(chu)。檢測(ce)時檢測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不宜(yi)過低，48V充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)檢測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)應大于40V以防(fang)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)由(you)于負(fu)載過大保(bao)護而中斷輸出(chu)(chu)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流逐(zhu)漸降低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)逐(zhu)漸升高(gao)直至轉(zhuan)態電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流轉(zhuan)態時的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流為(wei)轉(zhuan)態電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，轉(zhuan)態前的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)最高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，轉(zhuan)態后的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)轉(zhuan)態電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流檢測(ce)時應避免(mian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流過低以防(fang)輸出(chu)(chu)中斷。

2、10小時定時功能檢測
