每天30km （有人说车厂举例说在德国每天【太阳能(000591)、股吧】充的电能跑30km）, 对很多人来讲就足够了。就是所谓的买菜车。 我前几年每天开大约15km（上下班，接送小孩上学，附近超市买菜）。我的同事里面大约有一半以上都住在离公司不超过10km的地方，每天30km也够了。 我挪威的同事买了个日产的小型电动车，冬天也开不了多少公里就没电了，但他说作为买菜车足够了 （他每天40KM），他家还有一辆大的烧油的车，可以用来跑远途或者跑山上。

注意，这个德国太阳能车不仅仅有太阳能充电，还可以插电充电。Imagine an $18,000 electric vehicle that charges itself using solar power. It’s on the way in 2019.

The new Sion Solar Car is the first mass-produced electric car that can charge itself with integrated solar energy capacity. The compact minivan by the German startup, Sono Motors, has 330 monocrystalline solar cells built into the body. Located in the sides, roof, and rear of the car’s exterior, its solar cells add up to an extra 18 miles to its 155-mile range.

这就是你说的量产的太阳能汽车？太阳能板能提供155英里航程的电动汽车额外的18英里航程？

The 35 kW battery can receive supplemental power during daylight hours with the viSono solar charging system totaling 1,200 watts of supplemental power per day. The car needs to be parked outside to charge and the exact amount of power generated depends on the available solar radiation. The Sion also has plug-in capabilities that allow it to charge more quickly.

35kWh的电池，汽车太阳能板每天产生1.2x8kWh的电能（假设按日照时间8小时计算）。
充电4天，跑155+18=173英里。

好吧，也许上下班够用了，还得希望每天大太阳。

实际来讲，厂家宣传数据打个8折，太阳能板每天充电8kWh，按Tesla100kWh/500km的宣传数据打个8折，基本晒一天大太阳跑个30KM靠谱。
这种车的实际用途在哪里？
