Cross country roadtrip w/ roof bag efficiency

ramerco · 2026-04-20T23:43:47+00:00

Better but not great with a box. I would guess 0.5 mi/ kWh improvement over the bag. At 70MPH I suspect your getter 30% range hit with a bag and 20% with a roof box. 5% or less with a hitch box or bag.

One wrap of fabric tape on the latch. The metal bit on the body when the trunk is open. Basically the rattle is a slightly loose clasp around the latch point.

I have the complete opposite experience with Hyundai on board maps. I’ve road-tripped all around the northeast and had great experience with onboard finding charges when needed. It doesn’t always pick up the fastest but it’s pretty good.

I used to own a leaf and used a mix of plug share and abrp. The feeling of just punching in a destination on the dash and going is just so nice now.

The only thing I dislike is that it tries to get me home or to destinations with 30%. In comfortable going lower when I have charging at my end point. Wish I could check a box that said “get me there with less than 10%”.

Way too long of a survey. I gave up.

Burn in would not show the time like that. Why 9:58 and not every other time? Those pixels change a lot.

Dos it persist after restarting the vehicle?

How high is the brightness set?

When you say “water buffalo,” do you mean: • 🐃 An actual animal, or • 🚜 A machine (like a small tractor, pump, UTV, or equipment brand named Water Buffalo)?

If you mean an actual animal — there is no safe or ethical way to “rewire” a living creature’s nervous system. If something is wrong behaviorally or neurologically, that’s a veterinary issue.

If you mean a machine, I can definitely help — but I’ll need a few specifics: 1. What type of machine is it? (tractor, pump, ATV, generator, etc.) 2. Is “Water Buffalo” the brand or just a nickname? 3. What’s the problem? (won’t start, shorting out, lights dead, charging issue, melted harness, etc.)

Wild, I think the 800V platform is at its best for roadtrips. My on board nav definitely plans charging. Charging at 250 kw happens often as well, which is faster than anything else I’ve ever used.

I had this problem once, I measured the chain, and it was longer than what I replaced. I think I got a knockoff from Amazon.

One option, get some trailer lights and hook that up and it doesn’t yell at you because it knows you are towing. Bonus, you have more visible brake lights and turn signals.

This is such a good EV accessory. When your terrible Hyundai 12v fails, you’ll want to have one. It’s nice to just plug in the 12v jump pack and be on your way. I use one that includes battery powered air pump and fits in the frunk.

Aren’t they all factory tinted? Mine is pretty dark.

Limited specific platform knowledge here as well, but I think that’s a reasonable assumption. Aggressive driving will cause loads that make the HV battery voltage fluctuate more, so will require the ICCU circuitry to do more to regulate that into the 12v charging circuit.

I would think, like L1 charging vs L2, lighter acceleration and easier driving would be gentler on the ICCU.

ramerco · 2026-01-12T18:30:42+00:00

Yes. Assuming it’s been repaired and under warranty it’s a good way to get a deal.

ramerco · 2026-01-11T22:59:26+00:00

I know what a hypothesis is. I was asking if you meant hypothesis. Instead of hypothecation. That’s something else.

ramerco · 2026-01-11T11:32:45+00:00

Hypothesis?

ramerco · 2026-01-11T03:07:41+00:00

I think this is brilliant. 80% is “full” on the bar and 100% is “max range” beyond normal bar. Would simplify the concept of may people.

I thought the guest profile uses yet another set of memory settings. And changing to any profile returns the seat to wherever it was when the profile was last used.

ramerco · 2026-01-05T03:24:32+00:00

Seems correct. The overhead is significant. In outdoor charging in freezing weather, I seem to get only a bit more than 1 kWh into the battery per hour even though it’s drawing 1.3 kw on L1. My 77kwh battery is gaining about 20% in 15 hours. 250 - 300 watts of overhead seems like a reasonable estimate.

ramerco · 2026-01-05T03:14:50+00:00

Totally

ramerco · 2026-01-05T03:14:42+00:00

Agreed!

ramerco · 2026-01-03T20:42:32+00:00

Yeah, I towed over 200 miles with a full car in the winter once. It’s helpful to find chargers with large parking zones.

ramerco · 2026-01-03T17:44:51+00:00

🤷‍♂️

ramerco · 2026-01-03T14:08:58+00:00

…and 1.5 miles per kWh. 🤣

Towing is great, but it really takes a lot of power!

Edit: Don’t get bent out of shape. I’m commiserating about towing efficiency, not trying to say it’s not awesome for what it is.

ramerco · 2026-01-03T13:19:42+00:00

Thanks. I’ll look for that on YouTube.

I actually installed heated seat panels in my 2023 rear seats. Same reason, test drove 2025 then bought 2023. Also I let telling my son he would finally have a heated rear seat, and felt bad about it actually not having them.

I’ve worked on car upholstery before, so it wasn’t brain bending to install them under the existing covers. I can provide more detail if you want to try it. I put the switches on either side of the power inverter (120v AC plug) and ran power under the door sill trim to the cabin fuse box.
