OK, SPARKEV - since you've been so helpful (Thanks!) can I just run some things by you? I have verified that my outlet is grounded, got a good 12/3 20 amp rated extension cord for plugging in at home (cord should be long enough, but just in case), signed up for both ChargePoint and SemaCharge. I went to PlugShare and I verified that in Cisco Grove (from what it appears) the Chevron has an L2 charger and it's $2.00 for 2 hours of charge. I also tried calling Boreal, they are closed for the season (not sure why....lots of snow still!) so I couldn't verify over the phone that it was operational, but it looks like someone checked in there yesterday....so I am guessing it is good?
So I start in Auburn (elevation 1200') with 18 kWh and drive to Colfax, CA (16.6 miles away, elevation 2400'). So that uses about 5 kWh (4 for miles, 1 for elevation) and leaves me with 13. So it looks like the L3 in Colfax is EVGo - I can get that without the card, right? I mean, I can pay there with a regular Credit Card, right? It seems like I'm going to paying a lot for a little bit of juice, but oh well. I'm getting a great deal on the car. Since it's a level 3 I should be able to top off in about 20-30 minutes?
From Colfax I head to Cisco Grove (31 miles away, elevation 5500') - this consumes 14 kWh (8 mileage, 6 elevation) - leaves me with 4 - probably not enough to make it to Boreal straight through. I stop at the L2 at Chevron, charge for two hours, I get about 6 kWh, bringing me back to 10.
I think I can skip the Boreal stop and go straight through to Truckee (21 miles away, elevation 5800') - The elevation change balances (up 2000, down 1400) so that is about 1 kWh +5 for mileage. The instant I get to Donner I immediately bite my wife (sorry, dry sense of humor) but then shift into "L" for maximum regeneration. Worst case I'm back to 4 kWh. I stop at the Save Mart in Truckee (side question - can I use the Tesla Superchargers for the Spark EV?) and fill up. I need 14 kWh, so that takes probably about 40 minutes. Back to 18kwh.
Leave Truckee on 18, 31.5 miles to Reno, still in L. 8 kWh to get to Reno, minus whatever I can generate on the way back down. I'm home!
Does my math look good?
* Auburn (elevation 1200', 18 kWh) to Colfax (16.6 miles away, elevation 2400'). So that uses about 5 kWh (4 for miles, 1 for elevation) leaving ~13 kWh.
Yup, that looks right - you might use a lot less (?half?) kWh at 50mph, but your estimates should be conservative for planning this trip!. If the Chevy dealer in Colfax will let you charge there (call ahead), you might want to do that instead of L3 charging. Price is $10 for 30 mins of charging at EVgo, and you will only charge for maybe 10-15 mins. Is it worth $10 to save yourself 60-80 minutes? Your call. There's also a L2 charger at the Amtrak station (near the EVgo fast charger). You can view this as a quick test to make sure you know how to L2 charge before getting halfway up the mountain.
* Colfax to Cisco Grove (31 miles away, elevation 5500') consuming 14 kWh (8 mileage, 6 elevation) - leaves ~ 4 kWh. Stop at the L2 at Chevron, charge for two hours, add about 6.5 kWh, leaving ~ 10 kWh in battery.
{{ If EV charger at Chevron is blocked, broken, or in use, you have to choose whether to simply wait, attempt to make it to Boreal, or try to plug in your L1 EVSE at a regular outdoor plug at the Chevron while waiting. It's only ~12 miles to Boreal from here, but if you run out of juice, you're
totally screwed - you will have to call a flatbed to tow you. If driving conservatively on the way up, you might get to Cisco Grove with over 20 miles range showing on the range estimate. If you can immediately charge at Chevron (charging station is avail), I definitely would stop here and charge (no matter what) - safe is much better than sorry. }}
* You can
not use Tesla charge stations at all - any Tesla charger, not just Superchargers - the plugs are different
* If you charged at Chevron (Cisco Grove), you can skip Boreal. If you couldn't/didn't charge at Chevron, stop at Boreal. Before the trip I would contact the last person who logged a visit to Boreal on plugshare (Shadow) and ask for advice // lay of the land at Boreal. (Using the plugshare app you can contact a user : click/tap/touch the person's report and "message" them. Remember to mention the station name {Boreal} - the app is too stupid to include that info in the message.}
* Truckee Save Mart. At this point you will be really tired of waiting for the car to charge, so just use the EVgo fast charger, plug in for 30 minutes (or until almost full) - $10. You really only
need about 8 kWh (half tank) to get home from here, but you are paying a flat rate (and "better safe than sorry"). You don't want a
completely full battery at the top of the mountain (read about this below). The L3 charger should tell you what % battery charge you have as you are charging, and the % should increase while charging (duh). At Truckee (the top of the mountain) I'd stop charging at about 80% full (you'll see why below). If for some reason you can't use the EVgo chargers, there are a few L2 (much slower) chargers elsewhere in town. But remember - "better safe than sorry". If you have at least a half battery when you leave Truckee, you should make it home - you are going to get to the bottom of the hill with more energy than you had when you left Truckee (unless the battery was already full - you can't get more than 'full'

).
* After Truckee: once I-80 flattens out just before you get to Nevada - slow down to 55 or so until you are comfortable that you have enough range to get home.
NOTE on the "range" estimator. It is called (in slang) the GOM (for
Guess -
O -
Meter). It is an
estimate based on your recent driving. So, imagine that you have
just driven 15 miles down a mountain, adding energy to the battery instead of using energy. Do you think that the range estimate is going to be accurate? Hint:
NO! The computer will be using energy consumption info that is way too low, based on your last 15 minutes of driving. So, keep an eye on your GOM for 10-20 miles after you get to the flats and don't freak out if it starts dropping radically quickly. If it ever gets below 20 miles (it won't, not on this drive), find a place to charge (there are several around Reno, if you have a ChargePoint card).
* Where are you in relation to the "spaghetti bowl" (I-80/US-395 junction)? North, East, South, or West?
A few other notes :
- you shouldn't have to tailgate trucks (drafting) - so don't. they hate it, it's dangerous, etc. It's a last resort.
- use cruise control, on the way up hills AND down. The EV will keep you more or less at the exact speed (stay in 'L') - that is one of the advantages. When you are going downhill, it uses regenerative braking to maintain your speed, unlike a gas car which picks up speed on down-slopes when in cruise control. Well, unless the battery is already full. And of course, if you are using cruise control, you shouldn't be close to cars in front - another reason NOT to tailgate.
- When you are in 'L' mode (poorly named, it isn't for "Low gear", it is for max regen), lifting up on the accelerator will cause you to slow down - even 'brake'. You can pretty much 'one pedal drive' this vehicle in 'L', only using the brake pedal to slow down under 5-6 mph at stop signs/lights. In 'D', you 'coast' pretty much like a gas car. In 'L', when you lift up on the accelerator, you brake. In the Spark EV, the brake pedal FIRST increases regenerative braking, and if you press down further/harder on the pedal it uses friction brakes (well, unless the battery is full).
- If the battery is full, you do NOT get a regenerative braking effect (the battery is full - no place to put the energy) - you MUST push harder than normal to engage the friction brakes (i.e., use the brake pads). Don't get surprised by this.
Especially about half-way down the mountain after leaving Truckee. The braking behavior will change if you manage to fill up the battery on the drive down the mountain. (Yet
another reason to not tailgate ...)
- degraded battery. Batteries degrade over time - it is the nature of the beast. A Spark EV starts life with about 18.5 kWh battery, when new. The Spark you are buying may only have 17 kWh capacity left. Or 16 kWh. You *should* be able to easily make it to Reno (at 45 mph) using this plan so long as the battery will hold at least 15 kWh. The 'tight spot' is getting to Cisco Grove Chevron. As an emergency fallback, I would (1) keep my eyes like a hawk on the range meter on the drive to the Chevron, and (2) have a backup plan that consists of knowing where every convenience store/gas station is in the 15 miles before Cisco Grove in case you start to think you can't make it to CG - you pull in and beg on your knees to use a 120V socket to charge your car. I don't know how to easily explain how to check the capacity of the battery before purchase. Maybe somebody else can. As a data point, I have treated my battery very gently and have very close to 18 kWh capacity after 18 months.
- Your Level1 (120V) EVSE (that comes with the car). MAKE SURE it is in the car. Tell the seller s/he must demonstrate (to you) how to use it. Ask her/him to show/explain the messages on the instrument panel before and while charging (miles remaining, charge gauge/thermometer, text message/info screen, what it looks like when not charging, then when charging). That way you know : (1) that you have the EVSE and where it is, (2) that it works, (3) how to use it.
Oh, one last thing. I probably forget to mention this, but (1) regenerative braking doesn't work well if the battery is > 98% full, and (2) don't tailgate.
