特斯拉Model S低温无法充电 CEO正式致歉

感觉是应该是锂电池的特性造成的，怎么会跟电缆有关？理解不了。

0度以下就有问题？美国冬天这点温度不算啥，怎么没听说出问题的

特斯拉是不是被吹过头了 别压根不如比亚迪啊

电池、电池还是电池，什么时候电池有革命性发展了再来提电动汽车普及问题吧

是充电电缆的问题
早先美国有个杂志编辑开特斯拉沿东海岸旅行
就是晚上充了一晚上电 结果第二天跑了两三百公里就歇菜了
马斯克还说这个编辑胡扯不会开车
这编辑就说是因为晚上气温低 充电充不进去
这次特斯拉终于承认了

只遇到过电池在低温下电量减小的问题，还没听过说电缆在低温下不能给电池不能充电的问题。按照物理定律温度越低金属的导电性越好啊。要不然就没超导效应了。

充电线又不只是一根电线而已

不管几根线，只要是导体那么都要遵守物理定律。还有，电缆无法在低温下累积电荷，这是开玩笑吗？

你的手机电脑电源线难道就是一根电线？？？

18650电池嘛

那你告诉我电缆是干什么用的？是用于导电还是存电，在电路设计中电缆就是起到连接作用和信号传递作用，不管起什么作用都要遵守物理定律，因此我很好奇低温下电缆不能积累电荷是什么原理。
你说的几根线和原理有关系吗？

电池问题。锂离子电池在低温时荷电能力下降。至于电池管理系统，车的不清楚，像笔记本这种，零度以下会进行保护动作。

特斯拉死活不愿承认电池有问题而已。

0度以下就有问题？美国冬天这点温度不算啥，怎么没听说出问题的

在美国就出过问题
但是不常见
而且特斯拉知道有问题 但是你不问他就不说
特斯拉的发言人暗指挪威电网不稳定来推卸责任
我估计是低温+电压不稳导致适配器不能工作
可能是交变直的问题

主要有两个问题，一个就是车主预约充电时间的时候因为插上充电接头，12V电不再由主电池供应，也没有由插座供应，在寒冷的天气里，电池可能会失效，现在改成只要插上插座，就由插座的电供应，哪怕还没到充电的时间。

     
Firstly, when the charge port opens the high voltage battery is disconnected from the 12V system. The 12V feeding returns when the charge port closes and brake pedal is pressed. Therefore people who put their car into scheduled charging say 6PM and the scheduled charging starts at 6AM keep their 12V going without backup for 12h. During that time even if the car is connected to the grid the 12V is not touched at all therefore if you plan to keep the car in cold conditions etc try to limit the time charge port is open or start charging earlier at lower amps because the 12V is supported again when charging begins. This behavior. will change in the next firmware, then even when not charging, but connected to wall power the 12V is supplied from the wall.


      另一个就是软件上设置得对电压波动更不敏感些，如果电压波动，就降低充电电流一段时间后再尝试提高充电电流，不会像以前那样停止充电。

   
Secondly, the main reason for charging failures is abnormal variations in current. The new firmware (promised to me latest by this Friday) will make the car more tolerant allowing it to take what ever the wall supplies (so if the wall gives 13A, then 7A for a while, then 13A then the car won"t stop charging in the new fw, but will take what it gets). It should also make the charging more tolerant for other things, but they didn"t disclose what. They"ll try to push it to me today so we"ll see how things change. Also it should address the generic issues of charging failing to start when scheduled. So this is the Norway fix release  And I understand the generic push out for affected cars starts tomorrow or latest Friday.

  这位车主最后的结论是：
   最新的5.8.6版本看起来已经解决了充电难题，会先加热电池，然后再充电。
  
I can confirm that 5.8.6 seems to fix the scheduled charging issue. I had issues when the car was cold soaked and it started scheduled charging (i.e. I wanted it to start charging at 7AM but arrived home 6PM so 13h of standing in -20C). It just wouldn"t charge unless you turned on heating in the car and warmed the battery a bit. Got 5.8.6 yesterday with Tesla calling to confirm that this should fix my issue so yesterday I came home around 5PM and set scheduled charging at 9AM (so that people at Tesla would be in office) and it"s -19C outside (-15C in the car right now so it"s really cold soaked) and the car started charging at 9AM like clockwork. It"s currently drawing only 6 amps and not charging very fast, but that"s because it"s warming up the battery, that"s normal and what I had observed prior to 5.8.4 as well. I"d even assume the issue was not with cold per-se, but with 5.8.4 firmware that caused most of the charging issues that got fixed in 5.8.6.
    以前的版本因为考虑不周全，车主必须多次插拔插座，或者打开加热功能，然后才可能开始充电。

tesla电池充电主要还是软件问题。

换没有任何恒温设施的e6，去东北跑一个冬天看看。

反正那么贵，直接瞄准人傻钱多的暴发户市场，我等屁民就看看笑话好了。

特斯拉出事，怎么e6中枪了。本来就是卖到北欧的货，自己没做好环境适应性测试能怪谁。如果如楼上说的在美国就曾出过问题，那就是特斯拉自己做死
