美國加利福尼亞州能源委員會日前通過電池充電器能效新標準，這一標準將從2013 年2月起執行。加州將是全美首個對電池充電器制定高能效標準的州。根據規定，2013 年2月后生產的充電器將開始執行新標準，重型設備如叉車的充電器新標準從2014 年2 月生效。2013 年2月前生產和銷售的充電器不受此規定約束。

　　該(gai)委員會稱，目(mu)前(qian)加州約(yue)有1.7億個電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)在(zai)使(shi)用，平(ping)均每(mei)個家庭約(yue)有11個電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，例如(ru)電(dian)(dian)(dian)(dian)腦、電(dian)(dian)(dian)(dian)話(hua)、電(dian)(dian)(dian)(dian)動工具(ju)、剃須(xu)刀、商品條碼掃描器(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)池(chi)(chi)動力高(gao)爾夫球車和叉車等都會用到(dao)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，這(zhe)些(xie)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)大多在(zai)充(chong)(chong)滿電(dian)(dian)(dian)(dian)后或在(zai)電(dian)(dian)(dian)(dian)池(chi)(chi)被(bei)取下(xia)后仍繼續(xu)通(tong)電(dian)(dian)(dian)(dian)，造(zao)成(cheng)能源消耗。

　　能源委員會表示，新的充電器標準將減少三分之二的能源浪費，每年為消費者節約近3 億美元，減少100萬噸溫室氣體的排放，相當于每年路上減少7.5 萬輛汽車的排量。全州每年將減少能耗2200 千兆瓦小時，相當于35萬個家庭的用電量。委員會稱，改進電池充電器能(neng)效無需(xu)花費(fei)太多(duo)，只需(xu)利用(yong)現成的開關，使充電(dian)器在充滿電(dian)后能(neng)自(zi)動斷電(dian)，僅需(xu)花費(fei)40 到(dao)50美分。
