我們知道，太陽能路燈的主(zhu)要能源是(shi)太(tai)陽能，所以它是(shi)路(lu)燈中最環保(bao)的，因為(wei)它是(shi)白天(tian)太(tai)陽光(guang)照射在(zai)太(tai)陽能電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)上，把光(guang)能轉變成電(dian)(dian)(dian)(dian)(dian)(dian)能存貯在(zai)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)中，再(zai)由蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)在(zai)晚間為(wei)路(lu)燈的LED(發(fa)光(guang)二極體)提供電(dian)(dian)(dian)(dian)(dian)(dian)源。下(xia)面(mian)，太(tai)陽能路(lu)燈技(ji)術人員為(wei)您解析太(tai)陽能路(lu)燈的主(zhu)要保(bao)護(hu)(hu)模式：模式一(yi)、直充(chong)保(bao)護(hu)(hu)點(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya):直充(chong)也叫急充(chong)，屬(shu)于快速(su)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，一(yi)般都是(shi)在(zai)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)較(jiao)低的時候用大(da)電(dian)(dian)(dian)(dian)(dian)(dian)流和相對(dui)(dui)高電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)對(dui)(dui)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，但是(shi)，有(you)個控制點(dian)(dian)，也叫保(bao)護(hu)(hu)點(dian)(dian)。直充(chong)保(bao)護(hu)(hu)點(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)一(yi)般也是(shi)“過(guo)(guo)充(chong)保(bao)護(hu)(hu)點(dian)(dian)”電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)端電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)能高于這個保(bao)護(hu)(hu)點(dian)(dian)，否則會造成過(guo)(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，對(dui)(dui)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)有(you)損害的。

模式二(er)、均充(chong)(chong)(chong)(chong)(chong)控制點電(dian)(dian)壓：直充(chong)(chong)(chong)(chong)(chong)結束后，蓄電(dian)(dian)池一(yi)般(ban)會被(bei)充(chong)(chong)(chong)(chong)(chong)放(fang)電(dian)(dian)控制器靜置(zhi)一(yi)段時(shi)間(jian)，讓其電(dian)(dian)壓自然下落，當下落到“恢復電(dian)(dian)壓”值(zhi)時(shi)，會進(jin)入均充(chong)(chong)(chong)(chong)(chong)狀態。均充(chong)(chong)(chong)(chong)(chong)，也就是“均衡(heng)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)”。均充(chong)(chong)(chong)(chong)(chong)時(shi)間(jian)不(bu)宜(yi)過長，一(yi)般(ban)為幾分鐘(zhong)(zhong)~十幾分鐘(zhong)(zhong)，時(shi)間(jian)設定太長反而(er)有害(hai)。對配備一(yi)塊兩(liang)塊蓄電(dian)(dian)池的小型系統而(er)言，均充(chong)(chong)(chong)(chong)(chong)意義(yi)不(bu)大。所以。太陽能路燈(deng)控制器一(yi)般(ban)不(bu)設均充(chong)(chong)(chong)(chong)(chong)，只有兩(liang)個階(jie)段。

模式三、浮充控制點(dian)(dian)電(dian)(dian)壓：一(yi)(yi)(yi)(yi)(yi)(yi)般是均充完畢后，蓄(xu)電(dian)(dian)池也被靜置一(yi)(yi)(yi)(yi)(yi)(yi)段時(shi)間(jian)，使(shi)其端電(dian)(dian)壓自(zi)然下落(luo)，當下落(luo)至維護電(dian)(dian)壓”點(dian)(dian)時(shi)，就進入浮充狀態。就類似(si)于小電(dian)(dian)流充電(dian)(dian)，電(dian)(dian)池電(dian)(dian)壓一(yi)(yi)(yi)(yi)(yi)(yi)低就充上一(yi)(yi)(yi)(yi)(yi)(yi)點(dian)(dian)，一(yi)(yi)(yi)(yi)(yi)(yi)低就充上一(yi)(yi)(yi)(yi)(yi)(yi)點(dian)(dian)，一(yi)(yi)(yi)(yi)(yi)(yi)股(gu)(gu)一(yi)(yi)(yi)(yi)(yi)(yi)股(gu)(gu)地來(lai)，以免電(dian)(dian)池溫度持(chi)續升(sheng)高，這對(dui)蓄(xu)電(dian)(dian)池來(lai)說(shuo)  是很有好(hao)處的。

模式四、過(guo)放(fang)保(bao)護(hu)終止電(dian)(dian)(dian)壓(ya)：蓄(xu)電(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)不能低于國標的規定值。雖然蓄(xu)電(dian)(dian)(dian)池(chi)廠家也有自(zi)己的保(bao)護(hu)參數(shu)，但最終還是要向國標靠攏的。為了安全起見，一般將12V電(dian)(dian)(dian)池(chi)過(guo)放(fang)保(bao)護(hu)點(dian)(dian)電(dian)(dian)(dian)壓(ya)人為加上0.3v作為溫度補償(chang)或控(kong)制電(dian)(dian)(dian)路的零點(dian)(dian)漂移(yi)校正，這樣12V電(dian)(dian)(dian)池(chi)的過(guo)放(fang)保(bao)護(hu)點(dian)(dian)電(dian)(dian)(dian)壓(ya)即為：11.10v，那么24V系統  的過(guo)放(fang)保(bao)護(hu)點(dian)(dian)電(dian)(dian)(dian)壓(ya)就為22.20V。
