Bakersfield to Santa Cruz and Return in a Chevy Bolt

Sun Jul 29, 2018 11:59 pm

We again put our Chevy Bolt through its paces with a 540-mile round trip from Bakersfield to Santa Cruz to visit friends.

Well, ok, we took the trip to escape Bakersfield's oppressive heat too. It was 63 F (17 C) when we left Santa Cruz and 104 (40 C) when we returned to Bakersfield.

The Bolt with its 60 kWh traction battery performed as expected. We consumed 133 kWh in total with 6% of that devoted to A/C and 1% to battery cooling. We didn't skimp on the A/C and drove with traffic. If you've driven on Hwy 99 you know that can mean traveling at close to 80 mph at times. Even the slow lane can cruise at 65 mph. There was no hypermiling on this trip.

Image

We would have preferred the more scenic route from Paso Robles on the 101 through the Salinas Valley but the critical DCFC stations were down. The two relatively slow Chargepoint stations (22 kW) in Paso Robles and King City are notoriously unreliable and sure enough users of Plugshare.com were reporting them off line.

Consequently, we had to take the more pedestrian Hwy 99 to Hwy 152 to cross the Pacheco Pass west of Los Banos. We stopped for a charge on each leg at EVgo's Madera station and it dependably was working. This route added about an hour to the trip, but it was workable and the trip was uneventful.

Image

We used ~35 kWh on each leg and arrived at the EVgo station with about 45% state-of-charge (SOC). We charged to 80%, adding about 25 kWh in some 40 minutes. We then arrived at our destination with about 25% SOC, slightly more than planned.

Unlike some EVgo stations, the Madera charger didn't time out after 30 minutes. We began with 47 kW from the nominally 50 kW station. Once the SOC reached 65% the car began limiting the power input. When we finished charging the car was drawing 24-27 kW.

On the outbound trip our consumption was only a few percent less than that estimated by Chevy Assist. We averaged 3.9 mi/kWh for the first leg and 4.1 mi/kWh on the second leg.

Image

We stayed at a Holiday Inn Express in Santa Cruz because it had two Tesla destination charges in the parking garage. At the hotel we charged up to 100% overnight for the first leg of the return trip. For how we did that, see First Use of JDapter Stub for Tesla Destination Charger to Chevy Bolt.

We consumed ~10% less on the inbound trip than that estimated by Chevy Assist. We averaged 4.1 mi/kWh on the first leg and 4.0 on the second leg ending in Bakersfield.

Our trip to Santa Cruz was our most extensive to date at freeway speeds. About three-quarters of the trip was driven at 65 mph or faster. Yet overall we averaged 4.0 mi/kWh on the 540-mile trip. This is better than the 3.8 mi/kWh of our 300-mile round trips to Grover Beach from Bakersfield, but in line with most of our other road trips.

The Bolt's big 60 kWh battery and the growing network of reliable DCFC stations now makes such trips a possibility.

I miss the Pacheco Pass since there is no DCFC north of Lost Hills on Interstate 5 before the 152.

Hopefully you took the scenic route:

152 to 156 through Dunneville (nice cafe stop for breakfast or lunch and supplies) to the 25 to 101 south briefly to the 129 to Watsonville and then the 1 up to Santa Cruz.

It is a really nice agricultural scenic drive!

We took 152 from Madera across the SJ Valley over Pacheco. Good straight road, but hot, hot, hot. The rest of the route is as you noted. Traffic was heavy going so I didn't enjoy it. Coming back it was pretty relaxed.

If you continued on the 152 past Casa de Fruita and did not switch to the 156, you missed the most beautiful aspects of the road trip to Santa Cruz (and instead went through “scenic” Gilroy).

I have never experienced heavy traffic on that route.

PS: when the Chargepoint in Paso Robles is down, I drive to the Marigold Center in San Luis Obispo to use the EVgo’s that are much faster charging

They may not be an option to you depending on your route.

I've used that station but SLO is out of our way to Santa Cruz. Our route would have brought us in to Paso Robles.

I understand.

When Paso Robles is down, I change my route from Interstate 5 to hiway 46 in Lost Hills to the 101 in Paso Robles to a route which puts me on the 101 further south to San Luis Obispo before Paso Robles

Good planning avoids the pitfalls
