今天早上在学校看到  tesla的model s

我们学校有EV的充电器

在充电

方向盘边上有一个比ipad大的屏幕

这辆车价格大概在70K以上。 一个小时的充电可以开5 mile。一个晚上充电开50 mile。一般上下班都没问题了。 一次full charge可以开大概 220 miles。tesla现在有一种 supercharger station,可以1小时充满电。

现在的问题还是 1个是价格,另外一个是supercharger station的覆盖。人们可不想开到一半抛锚了。。 觉得hybrid可能暂时是一个缓冲的好方法。

按照tesla的数据,  85kwh的电池,可以开150 mile左右。

roughly  1.76 mile/kwh 在Texas,电价是 8.51 Cents per kwh, 所以,大概是 1.76 mile/ 8.51cents, which translate into  20.68 miles/dollar

那一般的 sedan,比如说 Honda Accord, 28.6 MPG. 现在Texas的油价。 $2.5/Gallon, 所以 是 28.6/2.5 =  11.44 miles/dollar.

一般来说,一个星期,加一次油,30块钱。 如果要开同样的距离,充电的话,要 $16.6.

一个星期省 14块钱左右。  一个月省 56块钱,一年 才省 672 块钱? 就算充电都是免费的,

省 1300 一年? 那要开10年省 13K .

假设开10年换车。那么tesla的价格要低于 (Honda Accord + 13 K) 对于用户来说才是值得的。现在 Accord 算 25K. 那么tesla如果能低于 40k的话就算便宜了。 当然tesla的配置应该算luxury car了。 average luxury car 算 40 K. 如果tesla能低于 55K, 就算便宜的了。现在最低的model s,60k左右。

当然从大局来看,我们少消费了很多gas,用核能,或其他能量代替了. It is sustainable, but not cheap.
