That's some great data. I have spreadsheets going for all of my vehicles, and am looking forward to doing a similar analysis in the coming months as our ID4 becomes our primary vehicle.

Thanks for the data! I have similar spreadsheets (PM vs other costs) going for all of our vehicles, and I look forward to doing similar analysis in the coming months now that we have an ID4.
This is just the tip of the iceburg for the data... I have over 300 assets that I manage I use Fleetio for my information system, but they have some good spreadsheet templates if you are not managing as many vehicles... https://www.fleetio.com/tools/fleet-maintenance-spreadsheet

-Should only be two fluids to maintain, brake fluid and battery coolant. A quick search says most manufacturers say around 100,000 or 10 years for the coolant and brake fluid is 30,000/3 years. These are basically the same as a ICE car, and easy to do yourself. I'd recommend actually halfing those numbers.
-Then you have tires, most EVs go through tires faster than the average car, but the Slate being so light and having a less powerful motor, I think it should be pretty similar tire tread life as an average car.
-Registration, depending on where you live, might be higher. Reduced fuel cost should offset this.

I'm pretty new to looking into EVs. Why do they tend to go through tires faster?

There is a lot of speculation to this, and as tires for EV's begin to get better they will last longer.

But basically the vehicles are heavier, so as they turn, stop, accelerate they cause more wear than a comperable non EV. There is also some thought that the regenerative braking causes some extra wear, but im skeptical on that.

It really just depends on the tire, and the driver mostly if the vehicle will go through tires faster or not.

I have Police Vehicles in my fleet that cant keep a set of tires for more than 3 months, and i have a Leaf that has had the same set of tires for 7 years... you can find data that will support either side of the argument.

here is a decent video if you want a deep dive.

My goal is to charge my Slate 100% from excess home solar, no cost. Totally possible with extended battery, possible challenge with Standard. Leaving home is approx 1.5 miles down hill so that could be a brake wear factor. Not too concerned about tire wear/mileage.

if I could charge my Slate on the methane from my farts I could drive free. Just putting that out there in case there is a fart to voltage generator.

Unless the grade on the hill is extreme, I doubt the Slate will ever engage the brakes just going downhill. It should regen the whole way. One pedal driving in a Tesla, Bolt, etc will come to a dead stop on steep hills with only regen.

just limit the charging to 90% so that you have some room in the battery to store energy and use regen braking down the hill, youll gain a few percent on the way down.

That’s my hope. Years ago this was hard on my Sequoia front brakes. Hoping the regenative braking is a positive solution. Need to check, but 800-900 elevation change.

They are heavier. However, that said, I believe Mr. Slate is around 3000lbs, and not super duper godzilla heavy.
I think the Blank Slate will weigh 3,600 lbs and 3,900 lbs with the standard battery and extended battery respectively.

That's similar to the weight of a typical crossover SUV.

Thank you! I will check this out later today! Those things make sense, just hadn't really thought about it.

Are EV drivetrains completely maintenance-free? For how long? A decade and a half, and 250,000 miles, for example?

Can an electric motor make billions of revolutions over many years and never need any service whatsoever?

Doesn't seem likely.

Wouldn't the motor's bearings need to be serviced or something like that?

Aren't there gears involved? Not the differential gears, but the the simple single-speed gear reducer that's in lieu of the transmission in an ICE vehicle. Are those going to be Super Gears that just keep going and going like the Energizer Bunny with zero maintenance for years to come?

There is no oil, water or gas wear to worry about. The electric charge cost is lower than buying gas. The battery is the largest cost that will deteriorate over time. EVs weigh more than an ICE vehicle because of the battery. That means the braking and the tires will take a little more punishment. Overall the EV cost is much the same as ICE. We buy EVs because we do not want to pollute the environment.
No, cost of ownership is generally significantly lower on an EV than an ICE. It’s generally the upfront cost that is higher, but the Slate helps solve that problem. While batteries degrade, it is very unlikely you’ll have to replace it unless you keep it to 150k+ miles. Even then it will likely still be functional, just may have lost enough energy capacity to not be as useful for a car. While EV’s typically are heavier and have higher torque than ICE vehicles, the current weight of the Slate is actually pretty similar to its ICE counterparts because of their minimalist design approach. It is only like a hundred pounds or so heavier than the Maverick. Tires should last a similar amount of time to an ICE vehicles. Brakes will likely never need replaced as regen does most of their work. If you can plug in at home, you will save a significant amount over fueling up a gas vehicle. Cost of repairs should be low and will be DIY friendly based on what Slate has said. Being a new company, only time will tell with this specific vehicle, but the company has some very experienced people in their ranks that seem to have a good handle on how things work in the industry and they seem to genuinely want to change it for the better and make a truly affordable vehicle.

It does have oil but it's not a high temperature environment so that oil can last a long time think of a rear differential, but it has a filter and cooling. Probably a good idea to change it every now and then but they are considered "lifetime" fluids.
I've never heard of the bearings failing but that's a good question.
