It was so cold that the trains couldn’t operate and the diesel in the buses froze. But the Model S was just fine.</text></comment>

Looking at an LG datasheet I pulled online (&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.powerstream.com&amp;#x2F;p&amp;#x2F;LG-ICR18650HE2-REV0.pdf&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.powerstream.com&amp;#x2F;p&amp;#x2F;LG-ICR18650HE2-REV0.pdf&lt;/a&gt;) you can see:&lt;p&gt;Operating - Charging: 0-50C&lt;p&gt;Operating - Discharging: -20-75C&lt;p&gt;Storage (1 month): -20-60C&lt;p&gt;So starting at -20C you run into trouble!  Many people forget that the charging temperature range is narrower, but luckily if you are connected to a charger you could use some of that energy to run the Battery Thermal Management System.</text></comment>
