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(wai)甥女給電(dian)(dian)(dian)(dian)(dian)動車電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)忘(wang)了(le)時間，兩(liang)天兩(liang)夜后(hou)發現電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)“流水”報廢(fei)。自那(nei)時起，做(zuo)了(le)十(shi)幾(ji)年電(dian)(dian)(dian)(dian)(dian)工的(de)舅舅張(zhang)建彬就(jiu)將(jiang)此記在心(xin)頭(tou)。10年后(hou)的(de)今天，張(zhang)建彬終于做(zuo)出(chu)較成熟的(de)智(zhi)能充電(dian)(dian)(dian)(dian)(dian)器，只要(yao)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充滿電(dian)(dian)(dian)(dian)(dian)，充電(dian)(dian)(dian)(dian)(dian)器就(jiu)把(ba)電(dian)(dian)(dian)(dian)(dian)流徹底切斷，既(ji)避免了(le)過(guo)量充電(dian)(dian)(dian)(dian)(dian)對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)損(sun)害，又起到(dao)了(le)節能效果。
“充電時間(jian)再(zai)長也不怕”
張建彬(bin)高(gao)中只讀了半年，做電工已有20多年。目前，他在石家莊市計劃(hua)生育(yu)技術服務(wu)中心做電工技師(shi)。
56歲的張建彬從包里拿出智能充電器，個頭(tou)與(yu)一般(ban)充(chong)(chong)電(dian)(dian)(dian)器相差無幾。隨后，張(zhang)建彬隨手拿(na)出(chu)一個普通的(de)充(chong)(chong)電(dian)(dian)(dian)器，接上電(dian)(dian)(dian)源。“你看，正常的(de)情況(kuang)下(xia)，充(chong)(chong)電(dian)(dian)(dian)器上的(de)綠(lv)燈亮了(le)，說(shuo)明電(dian)(dian)(dian)滿了(le)不必(bi)再充(chong)(chong)了(le)。”張(zhang)建彬又在(zai)充(chong)(chong)電(dian)(dian)(dian)器上接了(le)一個電(dian)(dian)(dian)壓表，指針一下(xia)子跳到“51伏”的(de)位置(zhi)。“這說(shuo)明還(huan)有少(shao)量(liang)電(dian)(dian)(dian)流在(zai)輸送(song)。”張(zhang)建彬說(shuo)，如果不盡快拔掉電(dian)(dian)(dian)源，電(dian)(dian)(dian)池里的(de)電(dian)(dian)(dian)會過量(liang)，最終損(sun)害(hai)電(dian)(dian)(dian)池壽命。
“再看看這個智能的(de)充電(dian)(dian)(dian)(dian)器(qi)，充滿電(dian)(dian)(dian)(dian)了(le)(le)自動(dong)關閉電(dian)(dian)(dian)(dian)源，充電(dian)(dian)(dian)(dian)時間再長也(ye)不怕。”張建彬(bin)把智能的(de)充電(dian)(dian)(dian)(dian)器(qi)接上電(dian)(dian)(dian)(dian)源，又(you)接上電(dian)(dian)(dian)(dian)壓(ya)表(biao)，電(dian)(dian)(dian)(dian)壓(ya)表(biao)一動(dong)不動(dong)，之后又(you)用兩根手指頭(tou)(tou)觸摸電(dian)(dian)(dian)(dian)路接頭(tou)(tou)，“如(ru)果有電(dian)(dian)(dian)(dian)，我手指頭(tou)(tou)就著(zhu)了(le)(le)。”
多一部(bu)分電路(lu)控制電源(yuan)
“其(qi)實就(jiu)是(shi)(shi)比一(yi)般充電器多了(le)一(yi)部分電路，這(zhe)部分電路能在電池電量飽和后自(zi)動斷(duan)電。”張建彬說，“我琢磨了(le)十年才做(zuo)成，如果(guo)科學(xue)家想做(zuo)這(zhe)個，我估計就(jiu)是(shi)(shi)幾天的事(shi)兒(er)。”
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)池充滿后自(zi)動(dong)斷電(dian)(dian)。電(dian)(dian)路(lu)設(she)計(ji)利用原有的(de)四運放IC電(dian)(dian)路(lu)作電(dian)(dian)壓(ya)和比較(jiao)，通(tong)過精密穩(wen)壓(ya)等反饋延時電(dian)(dian)路(lu)，實現了(le)電(dian)(dian)池充電(dian)(dian)到極限時主動(dong)斷電(dian)(dian)。這個智(zhi)能充電(dian)(dian)器解決了(le)蓄電(dian)(dian)池在無人看管的(de)情況下容易充鼓充爆的(de)問題。
潛(qian)心10年搞發明
說起為啥做智能充電器，張(zhang)建彬介紹，大概在2000年，外甥女買(mai)了(le)一輛電(dian)動(dong)自行車，有一次她(ta)給電(dian)池充電(dian)“充了(le)兩天兩夜，電(dian)池流水了(le)。”拿到修(xiu)車那，師傅看(kan)了(le)看(kan)說“用(yong)不了(le)，換(huan)一個吧。”自從那時起，張(zhang)建彬對此事耿耿于懷，“鬧鐘都能自動(dong)響鈴，充電(dian)器也就能自動(dong)斷電(dian)啊！”
當時，他做智能充電(dian)(dian)(dian)器是心有余力(li)不(bu)(bu)足(zu)，畢(bi)竟自(zi)己學歷有限(xian)，但(dan)他有一(yi)股(gu)子犟脾(pi)氣，知難(nan)而上(shang)。起初他拆(chai)了不(bu)(bu)少鬧鐘，又拆(chai)了不(bu)(bu)少電(dian)(dian)(dian)子定時器材，琢磨里(li)面(mian)的技(ji)術。不(bu)(bu)過，早幾年(nian)的時候工作忙，到了2008年(nian)他開始集中(zhong)專研集成電(dian)(dian)(dian)路等方(fang)面(mian)的知識，“下班不(bu)(bu)回家，蹲在自(zi)己的辦公室里(li)，看書、實驗。”張建彬說，后來(lai)癡迷到周末也不(bu)(bu)回家，“老(lao)伴(ban)和我(wo)斗氣，叫我(wo)回家干(gan)活(huo)，我(wo)早上(shang)5點就起來(lai)，把活(huo)兒(er)干(gan)完就走，老(lao)伴(ban)就沒話說啦!”
為了(le)搞明(ming)白一(yi)點問題，張(zhang)建(jian)彬在2009年還去了(le)一(yi)趟(tang)北京(jing)，“問了(le)問專家，還找(zhao)來點必(bi)備的器材。”張(zhang)建(jian)彬說(shuo)，如今他終(zhong)于解決了(le)外(wai)甥女以(yi)前遇到的難(nan)題，“以(yi)后充(chong)電(dian)時間(jian)再長(chang)也(ye)不怕啦！”
