[车师傅 长期测试] 在上一期结尾,我曾预告本期将会开着荣威Ei5(参数|询价)出趟远门,现在我来兑现承诺。本次旅行的目的地是天津,距离北京不远,但考虑到荣威Ei5的续航能力,这个距离还是蛮具有挑战性的,尤其是在全程零度以下的冬天。废话不多说,充满电,收拾好行囊,拉上媳妇、岳父、岳母还得抱着娃,准备出发吧!
我们定于下午1点左右出发,所以上午我提前将车开到家附近的快充桩充电。充电前,车子的电量仅剩余18%,正好可以测一测它的快充表现。
不过当电量达到40%以后,充电功率就开始走下坡路了,直到停留在23kW功率的时候,才开始企稳。最终测得从18%充电到80%,用时50分钟;充电到100%,用时83分钟,也就是说从80%充到100%电量用了半个多小时。好在充电的时候我回家吃饭了,不然呆在车里这么久,真挺无聊的。
根据这么长时间我对荣威Ei5的了解,在我们全程开空调20度、满载、外界气温均处于零度以下,不刻意为了省电而降低速度的条件下,把它开到最终目的地比较悬。稳妥起见,我计划先在距离天津最近的徐官屯服务区充一次电。
行程开始,我们从通州出发,行驶6公里左右的城市低速路段,就可以走到限速100km/h的东六环,随后从徐庄桥直接上京津高速。
吃完饭后,我们立即出发赶往酒店。最终到达酒店的时候,车辆还剩下17%电量,全程共行驶了171km。令我们十分开心的是,在媳妇行程规划的时候,并没有考虑酒店会有充电桩,但这个酒店里面还是配备了特来电直流快充桩,这样我们就不用去酒店附近找桩充电了。
我能找到的一个合理解释是,由于荣威Ei5配备的是风冷电池,所以无法通过温控系统给电池预热,在零下四五度的寒冷环境下,电池充电速率会比较慢。
至此,第一天的行程全部结束。总的来看,虽说出行第一天在充电的时候出了点小意外,但整体行程并没有因为驾驶的是电动车,而有过多的麻烦,比我预想的要顺利。
