根據相關標準規(gui)定(ding)，電(dian)(dian)動自行車(che)(che)的最高(gao)(gao)車(che)(che)速，不能(neng)超(chao)(chao)過(guo)最高(gao)(gao)設計車(che)(che)速，且不超(chao)(chao)過(guo)25km/h。本次(ci)電(dian)(dian)動自行車(che)(che)抽查有2批次(ci)的產(chan)品(pin)該項目不合格(ge)，分(fen)別來自丹尼騎和優速。其中(zhong)1批次(ci)的實(shi)測值25.4km/h，超(chao)(chao)標準值0.4 km/h；另1批次(ci)的實(shi)測值23.0km/h，并未超(chao)(chao)標準值，但(dan)企業明示的最高(gao)(gao)設計車(che)(che)速為18km/h，因實(shi)測值超(chao)(chao)最高(gao)(gao)設計車(che)(che)速被(bei)判為不合格(ge)。

另外，本(ben)次抽檢的三批(pi)次樣品照明不(bu)合(he)(he)格，分別來自(zi)優(you)速、愛(ai)瑪和(he)賽(sai)箭。其中有(you)一批(pi)次前燈(deng)(deng)不(bu)合(he)(he)格，2批(pi)次后燈(deng)(deng)不(bu)合(he)(he)格，均為亮度值達不(bu)到標準要求。

在電(dian)動(dong)自行(xing)車(che)蓄電(dian)池充(chong)電(dian)器(qi)不(bu)合格(ge)項(xiang)目上，兩(liang)款(kuan)(kuan)天能電(dian)池專用(yong)充(chong)電(dian)器(qi)樣品(pin)和(he)一(yi)款(kuan)(kuan)綠亮(liang)電(dian)動(dong)車(che)專用(yong)充(chong)電(dian)器(qi)樣品(pin)不(bu)達標(biao)。

上(shang)海市(shi)市(shi)場監(jian)管局提醒，電動自行車如果(guo)使用輸入、輸出線及插(cha)頭不(bu)合格的產品時，有(you)直接插(cha)在(zai)220V交(jiao)流電上(shang)使用的風險，一(yi)旦出現這種情況，就有(you)可能產生觸(chu)電、起火等安全(quan)隱患。

對此，上海市市場監管(guan)局建議，電動自行(xing)車要根據(ju)自身的使用(yong)需求(qiu)選(xuan)(xuan)擇，并(bing)不是續行(xing)里程越長(chang)(chang)越好(hao)(hao)；要選(xuan)(xuan)擇已取得3C認證(zheng)且常見的好(hao)(hao)口碑(bei)品牌，也要挑選(xuan)(xuan)經營時間長(chang)(chang)信譽好(hao)(hao)的商家，可以確(que)保售后服務(wu)得到(dao)保證(zheng)；不要追求(qiu)大(da)功率和高車速(su)。

同時(shi)，在給(gei)電(dian)(dian)(dian)(dian)(dian)動自行車充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)，謹防雨(yu)淋、高溫(wen)、陽光直(zhi)射；不要在樓道內給(gei)電(dian)(dian)(dian)(dian)(dian)動自行車充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，不要飛線充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，盡量避免(mian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)間過長等情況(kuang)；盡量避免(mian)電(dian)(dian)(dian)(dian)(dian)動自行車蓄電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器顛簸；當充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器在充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)，嚴禁在表(biao)面用(yong)其他物品覆蓋。
