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)動車電(dian)池(chi)充(chong)電(dian)忘了時間，兩(liang)天兩(liang)夜后發現電(dian)池(chi)“流水”報廢。自那時起，做了十幾年電(dian)工的(de)舅舅張建彬(bin)(bin)就將此(ci)記在心頭。10年后的(de)今天，張建彬(bin)(bin)終于做出(chu)較成熟的(de)智能充(chong)電(dian)器，只要電(dian)池(chi)充(chong)滿(man)電(dian)，充(chong)電(dian)器就把(ba)電(dian)流徹底切斷，既避(bi)免了過量充(chong)電(dian)對(dui)電(dian)池(chi)的(de)損害，又起到(dao)了節能效果。
“充電時間再長(chang)也不怕”
張建彬高中只讀了(le)半年(nian)，做電工已有(you)20多年(nian)。目前，他在石家莊市(shi)計劃(hua)生育技術服務中心做電工技師。
56歲的張建彬從包里拿出智能充電器，個(ge)頭與一(yi)般充(chong)電(dian)器(qi)(qi)相差無(wu)幾。隨后，張(zhang)建彬(bin)隨手(shou)拿出一(yi)個(ge)普(pu)通的充(chong)電(dian)器(qi)(qi)，接上電(dian)源。“你看，正(zheng)常的情況下，充(chong)電(dian)器(qi)(qi)上的綠燈亮了(le)，說(shuo)(shuo)明電(dian)滿了(le)不(bu)必(bi)再充(chong)了(le)。”張(zhang)建彬(bin)又(you)在(zai)充(chong)電(dian)器(qi)(qi)上接了(le)一(yi)個(ge)電(dian)壓(ya)表，指針一(yi)下子(zi)跳到“51伏”的位置。“這說(shuo)(shuo)明還(huan)有(you)少(shao)量電(dian)流(liu)在(zai)輸送。”張(zhang)建彬(bin)說(shuo)(shuo)，如果不(bu)盡快拔掉電(dian)源，電(dian)池里的電(dian)會過量，最終損害電(dian)池壽命。
“再看(kan)看(kan)這個智能的充(chong)電(dian)(dian)(dian)(dian)器，充(chong)滿電(dian)(dian)(dian)(dian)了自(zi)動關閉電(dian)(dian)(dian)(dian)源(yuan)，充(chong)電(dian)(dian)(dian)(dian)時間再長也不(bu)怕。”張建(jian)彬把(ba)智能的充(chong)電(dian)(dian)(dian)(dian)器接(jie)上電(dian)(dian)(dian)(dian)源(yuan)，又(you)接(jie)上電(dian)(dian)(dian)(dian)壓表(biao)，電(dian)(dian)(dian)(dian)壓表(biao)一動不(bu)動，之后(hou)又(you)用兩根手(shou)指(zhi)頭觸摸電(dian)(dian)(dian)(dian)路接(jie)頭，“如果有(you)電(dian)(dian)(dian)(dian)，我手(shou)指(zhi)頭就著了。”
多(duo)一部分電路(lu)控(kong)制電源
“其實就是比一(yi)般充電(dian)器多了一(yi)部分(fen)(fen)電(dian)路，這(zhe)部分(fen)(fen)電(dian)路能(neng)在電(dian)池電(dian)量飽和后(hou)自動斷(duan)電(dian)。”張(zhang)建(jian)彬說，“我(wo)琢磨(mo)了十年才做(zuo)成(cheng)，如(ru)果科學家想做(zuo)這(zhe)個，我(wo)估計就是幾(ji)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)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)滿(man)后自動斷電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)路(lu)設計利用原有的四運放IC電(dian)(dian)(dian)(dian)路(lu)作電(dian)(dian)(dian)(dian)壓(ya)和比(bi)較(jiao)，通過精密穩壓(ya)等反饋延時電(dian)(dian)(dian)(dian)路(lu)，實(shi)現了電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)到(dao)極限(xian)時主動斷電(dian)(dian)(dian)(dian)。這(zhe)個智(zhi)能(neng)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器解決了蓄電(dian)(dian)(dian)(dian)池(chi)在無人看管的情況(kuang)下容(rong)易充(chong)(chong)(chong)鼓(gu)充(chong)(chong)(chong)爆的問題。
潛心10年(nian)搞發明
說起為啥做智能充電器，張建(jian)彬介紹，大概在2000年，外甥(sheng)女(nv)買了(le)(le)(le)一輛電(dian)(dian)動自(zi)行車(che)，有一次(ci)她給電(dian)(dian)池(chi)充(chong)電(dian)(dian)“充(chong)了(le)(le)(le)兩天(tian)兩夜，電(dian)(dian)池(chi)流水了(le)(le)(le)。”拿到(dao)修車(che)那，師傅看了(le)(le)(le)看說“用不了(le)(le)(le)，換一個吧。”自(zi)從(cong)那時(shi)起，張建(jian)彬對此事耿(geng)耿(geng)于懷，“鬧(nao)鐘都能自(zi)動響鈴，充(chong)電(dian)(dian)器也就能自(zi)動斷電(dian)(dian)啊！”
當(dang)時(shi)，他(ta)做智能充電器(qi)(qi)是心有(you)余(yu)力(li)不足，畢竟自己學(xue)歷有(you)限(xian)，但(dan)他(ta)有(you)一股(gu)子犟(jiang)脾氣，知(zhi)(zhi)難而上。起初他(ta)拆了(le)不少鬧鐘，又拆了(le)不少電子定時(shi)器(qi)(qi)材，琢磨里面的(de)(de)技術。不過(guo)，早幾年(nian)的(de)(de)時(shi)候工作忙，到了(le)2008年(nian)他(ta)開始(shi)集中(zhong)專(zhuan)研集成電路等方面的(de)(de)知(zhi)(zhi)識，“下班不回(hui)家，蹲在自己的(de)(de)辦公(gong)室(shi)里，看書、實驗。”張建彬說(shuo)，后來癡(chi)迷到周末(mo)也(ye)不回(hui)家，“老(lao)伴和(he)我斗氣，叫我回(hui)家干(gan)活(huo)，我早上5點(dian)就起來，把(ba)活(huo)兒干(gan)完就走，老(lao)伴就沒話說(shuo)啦!”
為了(le)(le)搞明(ming)白一點(dian)問(wen)(wen)題，張建彬(bin)在2009年還去了(le)(le)一趟北(bei)京，“問(wen)(wen)了(le)(le)問(wen)(wen)專家，還找(zhao)來點(dian)必備(bei)的器材。”張建彬(bin)說，如今他終于解決(jue)了(le)(le)外甥女(nv)以前遇到的難題，“以后充電時(shi)間再長也不(bu)怕啦(la)！”
