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(zhun)從2014年2月生效。2013年2月前(qian)生產和銷售(shou)的充電器不受(shou)此規定約(yue)束。

      該委(wei)員會稱(cheng)，目前加州(zhou)約有1.7億個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)在(zai)使用(yong)，平均每(mei)個(ge)家庭約有11個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，例如電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動工具、剃須刀(dao)、商品條碼掃描器(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池動力高爾夫球車(che)(che)和叉車(che)(che)等都會用(yong)到充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，這(zhe)些充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)大多在(zai)充(chong)滿電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后或在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池被(bei)取下后仍繼(ji)續通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，造成能源(yuan)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)效無需花費太多，只需利用現成的開關，使充(chong)電(dian)器在充(chong)滿電(dian)后能(neng)自動斷電(dian)，僅需花費40到(dao)50美(mei)分(fen).
