电动车没有大幅提高续航里程的情况下,研发方向是不是应该转向快充技术?**
题主的思路大体是正确的,但有那么一点点偏差。
电动汽车确实不应该一味追求续航里程的提高,而应该在充电上下功夫 —— 除了充电速度之外,更重要的是充电便利性**。

## 一、60-100kW的充电速度很慢吗?

以特斯拉为例,目前Model 3双电机版最大充电功率250kW、标续版170kW[1];我自己开的小鹏P7最高在85kW左右。

当然,最大充电功率并不等于实际充电功率,国外Model 3的实测充电曲线如下图的蓝线[2]:40%SOC以下时可以实现195kW充电、50%/60%/70%/80%/90%SOC时分别降为154kW/107kW/89kW/57kW/32kW。

同时测试的奥迪e-tron的最大功率虽然不如Model 3,但平均功率却强得多。80%SOC时还有125kW的充电功率、96%时还有63kW的充电功率。
