My trip in Rex crossing the sierra nevada range

EVMan · Sep 10, 2017

Did a long trip crossing the high mountain range sierra nevada on a very hot summer day.
The car did quite well
My observations:

While climbing , i had lot of power and was among the fastest drivers
My SOC went down from 64% to 24% with REX running while uphill .

While downhill, i was not the fastest in speed , as i was regenerating continuously

Having AC running at full capacity at zero speeds is a big plus compared to ICE. It does it efficiently as well. I was caught in standstill traffic for an hour. This car is great in hot weather.

On the flip side, if it had been a cold day with the need of heating continuously , i would have done worse in efficiency . Consuming lot of energy , and not being able to use my heat of REX.

I used DC charging , during my trip , with my AC running. It was a hot day 105F / 40C
It looked like the car was not charging fast enough.
I think the charger said around 76 Amp. 3XX (358 or so ) volts at 25% charge . So the charging was reduced by the hot day ? It was a new NRG 100Kwh charger.

Thx

Thanks for the post. I'm curious about your route. Did you take 120 and head east or ?? What were your starting and ending points ?
I've also had problems with DC fast charge in hot weather. The charger will turn off after 5 to 15 minutes and will not restart. Very frustrating. I don't know if the charger was "broken" or what but when I returned on a cooler day it worked fine. Also, on the hot days in question, I returned home and was able to use the supplied L1 charger in my cooler basement with no problems.

I went by 80 and came back by 50 to lake Tahoe
50 has lot of traffic , but the S. lake tahoe view is better.

Also , since the car gas storage is very small, my additional gas can came in very handy and saved time

No spill worked well.

Does that can fit in the frunk?

Yes, After u remove the tools , which is quick and easy.
I padded with some plastic bags around
Carry can only in long distance. ( and take the small risk )
This can is cheap and best , i did lot of research . Its rated well for ease of use
Leave empty space for altitude and temperature change, carry about 2 gallon / 8 liters max.
