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(cong)2014年(nian)(nian)2月生(sheng)(sheng)效。2013年(nian)(nian)2月前生(sheng)(sheng)產和銷(xiao)售(shou)的充(chong)電(dian)器不(bu)受(shou)此規(gui)定約束。

      該委員(yuan)會稱，目前加州約(yue)有1.7億個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)在(zai)(zai)使用，平均每個(ge)家庭約(yue)有11個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，例如電(dian)(dian)(dian)(dian)(dian)(dian)腦、電(dian)(dian)(dian)(dian)(dian)(dian)話、電(dian)(dian)(dian)(dian)(dian)(dian)動工具、剃須(xu)刀、商品(pin)條碼掃描器(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)動力高(gao)爾夫球(qiu)車和叉(cha)車等(deng)都會用到(dao)充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，這些(xie)充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)大多在(zai)(zai)充滿電(dian)(dian)(dian)(dian)(dian)(dian)后或在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)被取下后仍繼續通(tong)電(dian)(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(xiao)無需(xu)花費太多(duo)，只需(xu)利(li)用現成的開關(guan)，使充電器在充滿電后能自動斷電，僅(jin)需(xu)花費40到50美分.
