The study compared cars that fast charge at least 90% of the time to cars that fast charge less than 10% of the time. In other words, people who almost exclusively fast charge their car and people who rarely fast charge.
The results show no statistically significant difference in range degradation between Teslas that fast charge more than 90% of the time and those that fast charge less than 10% of the time.
When is fast charging more likely to cause damage? There are several times when fast charging may impact your EV battery more. Avoid fast charging in extreme heat without preconditioning your battery. Preconditioning is when the car’s thermal management system pre-cools or heats the battery to accept a higher charge rate.
Typically, the battery will be preconditioned if you set your car’s navigation to a fast charge station. Similarly, precondition the battery before fast charging in extreme cold. Driving a bit before fast charging is often enough to warm up the battery or get to the fast charger using your car’s navigation. Avoid fast charging your EV at very low states or very high states of charge since battery resistance will be higher.

家里有啊,但是loaner的超冲免费啊,我为啥要自己掏腰包?再说了我前几天带孩子出去打球,没法回家充电啊。TNTCN 写了: 2024年 12月 3日 17:31 叫你狠劲草loaner。。。
家里没安装240v充电桩?
我要是家里不能充电,是万万不会买tesla的。tesla的super charge在休斯顿不比2.30$/gal的gas便宜。。。

反正就是买个特斯拉,天天得供着,不能草太狠,充电什么的还得准备半天。ignius 写了: 2024年 12月 3日 18:20 https://www.notateslaapp.com/tesla-refe ... dy-reveals

还真可能是这个道理。以前没想过。谢谢。geniushanbiao 写了: 2024年 12月 3日 15:33 很多人都有这个经历,有几个因素影响。我总结最主要的是很多人没有入冬给轮胎打气的习惯,所以很多人冬天轮胎都是低气压行驶造成油耗高。我们这边冬天大概在20-30F附近所以我一般找一个大概25F左右的天气把车停外面几小时然后把轮胎打气到规定值这样油耗就会恢复正常。这个气压会差很多,比如我的Sprinter后轮的cold inflation规定是70psi,如果我在秋天外面70F附近打70psi气压,到冬天30F附近的时候这个cold inflation能给我掉到63-65psi。
叔的话看看就行,叔只是来娱乐的

我的打气筒上有气压表,经常检查胎压,尤其是天变冷后,必须加点气,基本上始终维持在推荐的加2-3个psi。温度低于50,就有明显的耗油增加,低于45就更多了。跟预热也没关系。YouTube上有个好像叫小韩修车的解释过,好像是因为发动机的温度太低,办法是前面来个保温被子。我还真见过,原来以为是为了保护车头的漆。geniushanbiao 写了: 2024年 12月 3日 15:33 很多人都有这个经历,有几个因素影响。我总结最主要的是很多人没有入冬给轮胎打气的习惯,所以很多人冬天轮胎都是低气压行驶造成油耗高。我们这边冬天大概在20-30F附近所以我一般找一个大概25F左右的天气把车停外面几小时然后把轮胎打气到规定值这样油耗就会恢复正常。这个气压会差很多,比如我的Sprinter后轮的cold inflation规定是70psi,如果我在秋天外面70F附近打70psi气压,到冬天30F附近的时候这个cold inflation能给我掉到63-65psi。

那个小韩修车的视频看看就完了,他有很多观点也都不正确。就是一修车的,你指望他懂多少汽车设计和engineering?fard 写了: 2024年 12月 3日 20:13 我的打气筒上有气压表,经常检查胎压,尤其是天变冷后,必须加点气,基本上始终维持在推荐的加2-3个psi。温度低于50,就有明显的耗油增加,低于45就更多了。跟预热也没关系。YouTube上有个好像叫小韩修车的解释过,好像是因为发动机的温度太低,办法是前面来个保温被子。我还真见过,原来以为是为了保护车头的漆。
发动机在冬天和夏天完全预热之后的工作温度是几乎一样的,上下差不了几度,这个对油耗的影响几乎为0。天气对发动机的影响主要是预热时间,冬天预热时间长而且尤其刚启动时候汽油雾化很差,这都是造成油耗上升的罪魁祸首。如果是一直跑的话就不会有这问题,但是多数人用车都是这种预热-冷却-预热-冷却的循环。
前面盖棉被这个倒是有用,作用并不是保温而是减少散热水箱上的气流。

目前的电池技术条件限制下,电池车只适用于上下班买菜。出长途的话那很可能会不方便,破坏旅行的风险较高。而且有很多千里无人烟的旅游区,开电车去形同自杀式冲锋,出事的几率太高。这从hertz甩卖特斯拉的行为上就可以看出来,hertz有一年时间频繁发电车的coupon,但照样没几个客户买账,最后只能卖ddheart 写了: 2024年 12月 3日 16:52 你这个思维有个大漏洞那就是假设油车和电车需要充电的次数一样。实际上我如果开油车一星期至少一充,但是电车我在本地基本就没有在外面充过电,都是在家充。
