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。

　　該委員會稱，目前加州約有1.7億個電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)器在使用，平(ping)均每(mei)個家(jia)庭約有11個電(dian)(dian)(dian)(dian)(dian)器，例如(ru)電(dian)(dian)(dian)(dian)(dian)腦、電(dian)(dian)(dian)(dian)(dian)話、電(dian)(dian)(dian)(dian)(dian)動工(gong)具(ju)、剃須刀、商品條碼掃描器、電(dian)(dian)(dian)(dian)(dian)池動力高爾夫球車和叉車等都(dou)會用到充(chong)電(dian)(dian)(dian)(dian)(dian)器，這些充(chong)電(dian)(dian)(dian)(dian)(dian)器大多在充(chong)滿電(dian)(dian)(dian)(dian)(dian)后或(huo)在電(dian)(dian)(dian)(dian)(dian)池被取(qu)下后仍繼續通電(dian)(dian)(dian)(dian)(dian)，造成能源消耗。

　　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，改進電池充電器能效無(wu)需(xu)花費太多(duo)，只需(xu)利(li)用(yong)現成的開關，使充(chong)電(dian)器(qi)在(zai)充(chong)滿電(dian)后能自動斷電(dian)，僅(jin)需(xu)花費40 到50美(mei)分。
