@Nathan_2706:
$蔚来(NIO)$
帮大家好好算一算换电站的账。以2代换电站为例。一个站需要13块电池,以70度电池来算,电池成本大概需要7x13--91w。加上其他配套,撑死算他120w好吧。如果蔚来现存100w辆车,如果全部换成2代来配套。全国大概需要2000座到3000座2代站来配套。差不多就是30亿人民币的投入吧。可能你会问我为什么只有十几万辆蔚来,却又770座换电站。我把换电站算少了。其实不然,目前换电站是超前布置的,大多数换电站不饱和运转的。当然,你会说,怎么可能不饱和。我听说很多换电站都排队。其实换电站排队现象主要集中在市中心区域为主。市中心多是1代站,电池数量少。车主多,造成的不平衡。随着蔚来的车主越来越多,蔚来得到的数据越来越精确,自然会在排队多的区域多开站。为了不要太啰嗦,其他的原因我就不说了。2代站已经具备无人值守的能力了。之后维持换电站的人工成本只剩下维修人员的了。换电站的盈利能力会比充电桩强很多。换电站可以做到低谷充电,峰价买电。可以通过大数据精确控制充电成本。且频次会比充电桩高很多很多。不说挣钱,起码可以应付换电站运转成本。所以换电站属于一次性投入。免费换电只是目前的引流之计,收费是大势所趋。换电总得来说,是一笔非常合算的投入。想必研发而已,固定成本的投入不要太划算。有一点点理科知识的人都知道,电池充电想要压缩进半小时,目前来看都是很遥远的事情。换电还是能节约大量时间的。特别是中国,至少有一半以上的人,家中是不具备充电条件的。相信再过几年,陆陆续续的换电品牌会出现的。蔚来的换电站也会有升级。大家有不同想法可以留言,不要太简单粗暴,至少说明你不同意的原因。
