老電工10年發明智能充電器
智能充電器(上)與普通充電器相差無幾
10年前，外甥女給(gei)電(dian)(dian)(dian)(dian)(dian)動車電(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)忘了(le)(le)時間，兩天兩夜后發現電(dian)(dian)(dian)(dian)(dian)池(chi)“流水”報廢(fei)。自(zi)那時起，做了(le)(le)十(shi)幾年電(dian)(dian)(dian)(dian)(dian)工的(de)(de)舅舅張(zhang)建(jian)(jian)彬(bin)就將(jiang)此(ci)記在心(xin)頭。10年后的(de)(de)今天，張(zhang)建(jian)(jian)彬(bin)終(zhong)于做出較成熟的(de)(de)智能(neng)充電(dian)(dian)(dian)(dian)(dian)器，只要電(dian)(dian)(dian)(dian)(dian)池(chi)充滿(man)電(dian)(dian)(dian)(dian)(dian)，充電(dian)(dian)(dian)(dian)(dian)器就把電(dian)(dian)(dian)(dian)(dian)流徹(che)底切斷，既(ji)避(bi)免了(le)(le)過量充電(dian)(dian)(dian)(dian)(dian)對電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)損害，又起到了(le)(le)節(jie)能(neng)效(xiao)果(guo)。
“充電時間再(zai)長(chang)也(ye)不怕”
張建(jian)彬高中只讀了半年(nian)，做(zuo)電工(gong)已有20多(duo)年(nian)。目前，他在(zai)石家莊市計劃生育技(ji)術服務(wu)中心做(zuo)電工(gong)技(ji)師。
56歲的張建彬從包里拿出智能充電器，個(ge)(ge)頭與(yu)一(yi)般(ban)充(chong)電(dian)(dian)(dian)(dian)(dian)器相(xiang)差無(wu)幾。隨后，張建彬隨手拿出一(yi)個(ge)(ge)普通(tong)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)器，接上(shang)電(dian)(dian)(dian)(dian)(dian)源(yuan)。“你(ni)看，正常的(de)(de)情況(kuang)下(xia)(xia)，充(chong)電(dian)(dian)(dian)(dian)(dian)器上(shang)的(de)(de)綠燈亮了(le)，說(shuo)明電(dian)(dian)(dian)(dian)(dian)滿了(le)不必再充(chong)了(le)。”張建彬又在(zai)充(chong)電(dian)(dian)(dian)(dian)(dian)器上(shang)接了(le)一(yi)個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)壓(ya)表，指(zhi)針一(yi)下(xia)(xia)子(zi)跳到“51伏”的(de)(de)位置(zhi)。“這(zhe)說(shuo)明還(huan)有(you)少量電(dian)(dian)(dian)(dian)(dian)流在(zai)輸送(song)。”張建彬說(shuo)，如果(guo)不盡快拔(ba)掉電(dian)(dian)(dian)(dian)(dian)源(yuan)，電(dian)(dian)(dian)(dian)(dian)池里的(de)(de)電(dian)(dian)(dian)(dian)(dian)會(hui)過量，最終損害電(dian)(dian)(dian)(dian)(dian)池壽(shou)命。
“再看看這個智(zhi)能的充(chong)(chong)電(dian)器，充(chong)(chong)滿電(dian)了自動關閉電(dian)源(yuan)，充(chong)(chong)電(dian)時(shi)間再長(chang)也不(bu)怕。”張建彬把智(zhi)能的充(chong)(chong)電(dian)器接(jie)上電(dian)源(yuan)，又接(jie)上電(dian)壓(ya)表(biao)，電(dian)壓(ya)表(biao)一動不(bu)動，之后又用兩根(gen)手(shou)指頭(tou)觸(chu)摸電(dian)路接(jie)頭(tou)，“如(ru)果(guo)有電(dian)，我(wo)手(shou)指頭(tou)就(jiu)著了。”
多一部分電路控制電源(yuan)
“其實就(jiu)是(shi)比一(yi)般充(chong)電(dian)器多了(le)一(yi)部分電(dian)路，這(zhe)部分電(dian)路能在電(dian)池電(dian)量飽(bao)和后自動斷(duan)電(dian)。”張建彬說(shuo)，“我琢磨(mo)了(le)十年才做成，如果科學家想做這(zhe)個，我估計就(jiu)是(shi)幾天的事兒。”
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(shi)現電(dian)池充(chong)滿后自(zi)動斷電(dian)。電(dian)路設計利用原有的(de)四運放IC電(dian)路作電(dian)壓和比較，通過精密穩壓等反饋延時電(dian)路，實(shi)現了(le)電(dian)池充(chong)電(dian)到極限時主動斷電(dian)。這個智能充(chong)電(dian)器解決(jue)了(le)蓄電(dian)池在無人看管的(de)情況下(xia)容易充(chong)鼓充(chong)爆的(de)問題(ti)。
潛心10年搞發明
說起為啥做智能充電器，張建彬介紹(shao)，大概在2000年，外甥女買了(le)(le)一(yi)輛電動自(zi)行車(che)，有(you)一(yi)次她給電池(chi)充(chong)電“充(chong)了(le)(le)兩天(tian)兩夜，電池(chi)流水了(le)(le)。”拿到修車(che)那，師傅看了(le)(le)看說“用(yong)不了(le)(le)，換一(yi)個吧。”自(zi)從那時(shi)起，張建彬對此事(shi)耿耿于(yu)懷，“鬧鐘都能(neng)自(zi)動響鈴，充(chong)電器也就能(neng)自(zi)動斷電啊！”
當時，他做智能充(chong)電器是心有(you)余力不(bu)(bu)(bu)(bu)足(zu)，畢竟(jing)自(zi)己學歷有(you)限，但他有(you)一股子犟脾氣(qi)，知(zhi)難(nan)而上。起(qi)(qi)初(chu)他拆了不(bu)(bu)(bu)(bu)少鬧(nao)鐘(zhong)，又(you)拆了不(bu)(bu)(bu)(bu)少電子定時器材，琢(zhuo)磨里面(mian)的(de)技術。不(bu)(bu)(bu)(bu)過，早幾年的(de)時候工作忙，到了2008年他開始集中專研集成電路等方面(mian)的(de)知(zhi)識，“下班不(bu)(bu)(bu)(bu)回(hui)家(jia)，蹲在自(zi)己的(de)辦公室里，看(kan)書、實驗。”張建彬說(shuo)，后來癡(chi)迷到周末也不(bu)(bu)(bu)(bu)回(hui)家(jia)，“老(lao)伴和我(wo)(wo)斗(dou)氣(qi)，叫我(wo)(wo)回(hui)家(jia)干(gan)活(huo)，我(wo)(wo)早上5點就起(qi)(qi)來，把活(huo)兒干(gan)完(wan)就走(zou)，老(lao)伴就沒(mei)話說(shuo)啦!”
為了搞(gao)明白一(yi)點問(wen)題，張(zhang)(zhang)建彬在2009年還(huan)去了一(yi)趟北京(jing)，“問(wen)了問(wen)專家，還(huan)找(zhao)來(lai)點必備的器材。”張(zhang)(zhang)建彬說，如今他終于解決了外甥女以前(qian)遇到(dao)的難題，“以后充電(dian)時(shi)間再長也(ye)不怕(pa)啦！”
