一(yi)、電動車(che)智能充(chong)電器基本(ben)性能及參(can)數：

1、定時功能：舉例：48V 10AH 電動車充電器為例；

  起充電流＞1.5A（±0.1A）以上，進入10±0.5h定時。

  當(dang)電流降至＜1.5A（±0.1A）而大于1.1A（±0.1A）進入(ru)40±5min定時(shi)。

  當電流降至＜1.1A（±0.1A）而大(da)于500mA時(shi)取消前一(yi)階段的(de)40min定時(shi)，進(jin)入(ru)新的(de)40±5min定時(shi)。

  當電(dian)(dian)流(liu)降至＜500mA而大于(yu)轉燈電(dian)(dian)流(liu)時(shi)(shi)取消(xiao)前(qian)一階段的40min定(ding)時(shi)(shi)，進入新的40±5min定(ding)時(shi)(shi)。

  舉例(li)：48V 10AH 電動車(che)充電器為(wei)例(li)；

起充電流＞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(da)于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(xiao)前一階段的60min定(ding)時，進入新的60±5min定(ding)時。

  當(dang)電流降至(zhi)＜1.0A（±0.1A）而(er)大于轉燈電流時取消(xiao)前一階段的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(feng)不(bu)良(liang)導致溫(wen)升過(guo)高，變(bian)壓器溫(wen)度達到100℃時，充電器輸出(chu)電流減為1.3A左右（20AH的降至1.8A）。

3、反(fan)接保護(hu)：輸出反(fan)接時，充(chong)電(dian)器(qi)無輸出，充(chong)電(dian)器(qi)燈亮綠燈10秒鐘后(hou)指示燈紅(hong)綠燈交替(ti)閃爍(shuo)。

4、空載電(dian)壓(ya):空載無(wu)輸出電(dian)壓(ya)。

    二、電動車充電器保護功能檢測方法：
