智能充電器(上)與普通充電器相差無幾
　　10年(nian)前，外甥女給電(dian)動車(che)電(dian)池充電(dian)忘了(le)時(shi)間，兩(liang)天(tian)兩(liang)夜后發現(xian)電(dian)池“流水”報(bao)廢(fei)。自(zi)那時(shi)起(qi)，做了(le)十幾年(nian)電(dian)工(gong)的(de)(de)舅(jiu)舅(jiu)張建(jian)彬就(jiu)將此記在(zai)心頭。10年(nian)后的(de)(de)今天(tian)，張建(jian)彬終于做出較成熟的(de)(de)智能充電(dian)器(qi)，只要電(dian)池充滿(man)電(dian)，充電(dian)器(qi)就(jiu)把電(dian)流徹底切斷，既避免(mian)了(le)過(guo)量充電(dian)對電(dian)池的(de)(de)損害，又起(qi)到了(le)節能效果。

　　“充電(dian)時間再長也不怕”

　　張建彬高中只讀了(le)半年，做電工(gong)已有20多年。目前(qian)，他在石家莊市計劃生育技術服務中心做電工(gong)技師。

　 56歲的張建彬從包里拿出智能充電器，個(ge)頭與(yu)一(yi)(yi)般充(chong)電(dian)(dian)(dian)(dian)器相差無(wu)幾。隨后(hou)，張建彬隨手拿出一(yi)(yi)個(ge)普通的(de)(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)器，接(jie)上(shang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)。“你看，正常的(de)(de)(de)(de)情況下，充(chong)電(dian)(dian)(dian)(dian)器上(shang)的(de)(de)(de)(de)綠燈亮(liang)了(le)，說明電(dian)(dian)(dian)(dian)滿了(le)不必再充(chong)了(le)。”張建彬又在(zai)(zai)充(chong)電(dian)(dian)(dian)(dian)器上(shang)接(jie)了(le)一(yi)(yi)個(ge)電(dian)(dian)(dian)(dian)壓表，指針一(yi)(yi)下子跳(tiao)到“51伏(fu)”的(de)(de)(de)(de)位置。“這說明還有(you)少量電(dian)(dian)(dian)(dian)流在(zai)(zai)輸送。”張建彬說，如果不盡快拔掉電(dian)(dian)(dian)(dian)源(yuan)(yuan)，電(dian)(dian)(dian)(dian)池里的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)會(hui)過(guo)量，最終損害電(dian)(dian)(dian)(dian)池壽命。

　　“再看看這(zhe)個智能的充(chong)電(dian)(dian)(dian)器，充(chong)滿電(dian)(dian)(dian)了自動關閉電(dian)(dian)(dian)源(yuan)，充(chong)電(dian)(dian)(dian)時間再長也不怕(pa)。”張建彬把智能的充(chong)電(dian)(dian)(dian)器接上電(dian)(dian)(dian)源(yuan)，又接上電(dian)(dian)(dian)壓(ya)表，電(dian)(dian)(dian)壓(ya)表一動不動，之后又用兩根手指(zhi)頭觸摸電(dian)(dian)(dian)路接頭，“如果有電(dian)(dian)(dian)，我手指(zhi)頭就著了。”

　　多一部分(fen)電(dian)路控制電(dian)源

　　“其實(shi)就(jiu)是比(bi)一般充電(dian)(dian)器(qi)多了一部分電(dian)(dian)路，這(zhe)部分電(dian)(dian)路能(neng)在電(dian)(dian)池(chi)電(dian)(dian)量飽和后自動斷電(dian)(dian)。”張(zhang)建彬說(shuo)，“我琢(zhuo)磨了十(shi)年才做成，如果科學家想(xiang)做這(zhe)個(ge)，我估計(ji)就(jiu)是幾天(tian)的事兒。”

　　　在申請的說明書上記者看到介紹，稱此發明的目的是提供一種帶自動控制節能系統的智能充電器，實現電(dian)(dian)(dian)(dian)池充(chong)滿后自動斷電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)路設計(ji)利用(yong)原有的(de)(de)四運放IC電(dian)(dian)(dian)(dian)路作電(dian)(dian)(dian)(dian)壓(ya)和比(bi)較，通過精密穩壓(ya)等反饋延(yan)時(shi)電(dian)(dian)(dian)(dian)路，實現了電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)到(dao)極限時(shi)主動斷電(dian)(dian)(dian)(dian)。這(zhe)個智能(neng)充(chong)電(dian)(dian)(dian)(dian)器解決了蓄(xu)電(dian)(dian)(dian)(dian)池在無(wu)人(ren)看管的(de)(de)情(qing)況下(xia)容易充(chong)鼓充(chong)爆(bao)的(de)(de)問題。
