Re: 6600+ ft. of climbing / LEAF in the San Bernardino Mountains

Thu Dec 22, 2016 10:38 pm

Today I ended up driving our LEAF down the mountain to an appointment in San Bernardino, the first time taking it all the way "down the hill" in a few months, as my wife was already using our new-to-us 2012 Tesla Model S for a separate appointment.

This gave me an occasion to fire up LeafSpy and check the stats on our vintage 2011 battery, which are now: 48.46 Ah, SOH=73%, Hx=53.38%, 66536 miles, 132 QCs, 4790 L1/L2s

The bad news is that, with that battery at a temperature of about 41 F and a starting SOC of 80% (not planned well), the regen was almost non-existent. Thankfully, earlier this year, we had our warped brake rotors ground down by our local shop, so it was tolerable to use the friction brakes in the cold rain.

The great news is that there's now a working EVgo CHAdeMO/CCS station, with two separate quick chargers plus Level 2, right at the base of the mountain. It's now, by far, the closest QC to the primary route to Big Bear! See

So, all it took for me to return home was a single QC session, which raised the LEAF's charge to 59% in GIDs (an old metric that I'm used to) and the battery temperature to about 60 F. After driving 40-45 mph up the mountain, with traffic, and using the defogger sparingly, I pulled in our driveway with 11% in GIDs. There was no need for a Level 2 top-off! And there's a nice, new ALDI food market on the other end of the shopping center. That said, an EVgo a la carte quick charge is expensive, so we'll only do this occasionally, when the Tesla is not available. But if one already has an EVgo membership, this is a great option for visiting the mountain resort area in a LEAF or other EV.
2011 LEAF at 69K miles, pre-owned 2012 Tesla S 85 at 89K miles
LEAF battery: 9/12 bars and < 49 Ah (-28% vs. new)
Tesla battery: 250+ miles of range (-5% vs. new)

Thanks for pointing out the new DCFC at the Walmart. That makes a big difference (cutting off 10 miles from the 7-eleven) if you are heading all the way to Big Bear. I'm not sure if I will make the trek from San Diego again now that I have lost 10% of capacity, but at least I know making it up the hill would be no problem with the charger at the base.

Thanks for sharing... It would seem we are like the old model Ts that had to carefully roam about making sure gas was either strapped on board or in the landing range... On the other hand, electricity is well distributed. My thought is rather than big batteries, more fast chargers... But I digress. Thanks again for sharing the stats and outcome...
