如何看待丰田发布燃料电池轿车Mirai的第二代?丰田未来的新能源路线会是怎样的?**
我可能是知乎上为数不多一代和二代Mirai都开过的,可以跟题主分享一些自己的体验和想法。

先简单过一下FCV车型的能量转化原理。FCV车型的核心是燃料电池堆,这是一个让氢气与空气中氧气平稳、缓慢反应,释放电能的过程,也就是说FCV车型的排放只有水。初中咱们就做过电解水的试验,FCV的反应过程其实就是电解水的逆向。
FCV车型的能量流并不难理解,以第二代Mirai为例,它是通过燃料电池堆发的电驱动电机,同时还“并联”一块容量不到2kWh的小型锂电池,这块锂电池起到辅助蓄能的作用,燃料电池可以给它充电,车辆动能回收的电能也储存其中,这块小电池也会参与到驱动车辆。
