一(yi)、電動車智(zhi)能充電器(qi)基本性能及參數：

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(yu)1.1A（±0.1A）進入40±5min定時。

  當(dang)電(dian)流降至(zhi)＜1.1A（±0.1A）而大于500mA時取消前一階段的(de)40min定時，進(jin)入新的(de)40±5min定時。

  當電流降(jiang)至(zhi)＜500mA而大于轉(zhuan)燈電流時(shi)(shi)取消前一階段的40min定(ding)時(shi)(shi)，進入新的40±5min定(ding)時(shi)(shi)。

  舉(ju)例(li)：48V 10AH 電動車(che)充(chong)電器為例(li)；

起充電(dian)流(liu)＞2.0A（±0.1A）以(yi)上，進(jin)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定時。

  當電流降(jiang)至＜1.5A（±0.1A）而大(da)于(yu)1.0A（±0.1A）時取消前(qian)一階(jie)段的(de)60min定(ding)時，進入新的(de)60±5min定(ding)時。

  當電流(liu)降(jiang)至＜1.0A（±0.1A）而(er)大于轉燈電流(liu)時(shi)取(qu)消前一階段(duan)的60min定時(shi)，進入新(xin)的60±5min定時(shi)。

2、過熱保護功能

  由于外界溫度過高或者充電器充電環境(jing)通風不良導致(zhi)溫升過高，變壓(ya)器溫度達到100℃時，充電器輸出電流減為(wei)1.3A左右（20AH的降(jiang)至(zhi)1.8A）。

3、反接保護：輸出(chu)反接時，充(chong)電器無輸出(chu)，充(chong)電器燈亮綠(lv)燈10秒鐘(zhong)后指示(shi)燈紅綠(lv)燈交替閃爍。

4、空載電壓:空載無(wu)輸出(chu)電壓。

    二、電動車充電器保護功能檢測方法：

1、  充(chong)電(dian)(dian)(dian)器(qi)輸(shu)出線接(jie)(jie)通(tong)(tong)(tong)檢(jian)(jian)測(ce)儀(yi)檢(jian)(jian)測(ce)輸(shu)入端，按規定接(jie)(jie)通(tong)(tong)(tong)電(dian)(dian)(dian)源(yuan)充(chong)電(dian)(dian)(dian)器(qi)燈亮而無(wu)輸(shu)出，同時接(jie)(jie)入一只(zhi)同極性的(de)(de)普通(tong)(tong)(tong)充(chong)電(dian)(dian)(dian)器(qi)作(zuo)為(wei)觸發電(dian)(dian)(dian)源(yuan)，此時儀(yi)器(qi)有顯示電(dian)(dian)(dian)壓(ya)及電(dian)(dian)(dian)流(liu)，充(chong)電(dian)(dian)(dian)器(qi)正常輸(shu)出。檢(jian)(jian)測(ce)時檢(jian)(jian)測(ce)電(dian)(dian)(dian)壓(ya)不宜(yi)過(guo)低，48V充(chong)電(dian)(dian)(dian)器(qi)檢(jian)(jian)測(ce)電(dian)(dian)(dian)壓(ya)應大于40V以防(fang)充(chong)電(dian)(dian)(dian)器(qi)由于負載過(guo)大保護而中斷輸(shu)出，電(dian)(dian)(dian)流(liu)逐漸降低電(dian)(dian)(dian)壓(ya)逐漸升高(gao)直至轉(zhuan)態(tai)(tai)(tai)電(dian)(dian)(dian)流(liu)轉(zhuan)態(tai)(tai)(tai)時的(de)(de)電(dian)(dian)(dian)流(liu)為(wei)轉(zhuan)態(tai)(tai)(tai)電(dian)(dian)(dian)流(liu)，轉(zhuan)態(tai)(tai)(tai)前的(de)(de)電(dian)(dian)(dian)壓(ya)為(wei)最(zui)高(gao)電(dian)(dian)(dian)壓(ya)，轉(zhuan)態(tai)(tai)(tai)后(hou)的(de)(de)電(dian)(dian)(dian)壓(ya)為(wei)轉(zhuan)態(tai)(tai)(tai)電(dian)(dian)(dian)壓(ya)，低電(dian)(dian)(dian)流(liu)檢(jian)(jian)測(ce)時應避(bi)免電(dian)(dian)(dian)流(liu)過(guo)低以防(fang)輸(shu)出中斷。
