US-Made Slate EVs Could Fast-Charge At Home With Genius Canadian Tech

Vancouver-based Exro’s Coil Driver inverter technology will feature on low-cost SUVs and trucks from Bezos-backed startup

• Canada’s Exro will supply game-changing tech to EV startup Slate, Driving.ca reports.
• Exro’s equipment removes need for on-board charger, allows AC fast-charging at home.
• Slate is developing EV SUVs and trucks with $25k start price that should debut in late ’26.

The tech comes from Exro, which has developed its own Coil Driver inverter. The technology has several advantages, one of which is that it removes the need for a traditional on-board charger that’s necessary when converting AC power from your house to DC for charging an EV.

Ditching the converter makes the EV lighter and also cheaper to build – a big priority when you’re targeting a $25k retail price. But it also allows for faster AC charging, giving the possibility of sucking in 19 kW, with up to 80 kW possible in the future, according to Driving.ca, which broke the story. That doesn’t just mean easier charging at home, but would make it much easier for the global charging network to expand, because it removes some of the need to build expensive DC charging stations.


Another plus point to Exro’s tech is its coil-switching system. This effectively creates multiple virtual power and torque profiles in one motor, each configured to best suit what the driver and vehicle needs at that moment. The result is more bottom end torque and more top end power than with a conventional motor, plus greater efficiency.

My #1 reason for purchasing was for the opportunity to back feed my home and/or have plenty of power off-grid as the Ford Lightning has proven; especially with the new chargers that they finally got around to developing. What will Slate be saying about these capabilities in the near future and will they market it soon as such as Ford did from the beginning?

I definitely want a power output option as well for overnight camping mode. Would like to see 10 A 120 AC output. But just a DC port to which I could connect my own external inverter would be fine.

Yes the Lightning can do V2H but the slate has a tiny, half the capacity battery compared to the Lightning.

Not much energy to put back into a house......

"...The Nissan Leaf has a V2H function (it’s the only EV on the market with both V2G and V2H), and it can supply up to 7 kW of electricity and provide electricity to your home for around two days...."
So how does the Slate power plant compare to a Leaf and what is the comparative (minimum) kW value where any Slate owners would say 'meh'.
I've got a cheap Pecron 3600W solar/inverter/battery combo with a spare stackable battery at 3000W.
I'm tickled pink to have this connected to the house for even a few loads and would be thankful even more for the Slate to back up even one critical load to boot.
Storage to fill even a small portable power station is everything in my book. I like this set up as well to charge your EV for even a few miles in a pinch:

There are some terrific power station home backup systems on the market that would be a lot easier, and better, to use than the Slate. Draining the Slate battery so that the vehicle can't be used for its intended purpose leaves me scratching my head. That said, having some ability to use the battery while camping would be nice for DC loads...or to charge a portable power station. 400v is pretty nice, but dangerous in the wrong hands...a step-down converter would be needed. 800-1000 watts of output would be fantastic. A DC-AC inverter may be a cost Slate is not willing to add.

I could see this being a good short-term solution for a power outage to run your lights and TV for an hour or so until I fire up the generator.

it will have a V2L connection

Hey David, Thank you so much! We were absolutely blown away by how excited people were and all the support we have been getting! It feels phenomenal! Two things for you as well! We will have the option of having a V2L connection for tools and appliances and all that fun stuff! We will also with that have USB and USB-C connections available for you to plug your devices and more into. We will have a lot more information on all this coming out at we near production, so stay tuned! We've got a lot more exciting stuff coming! Lastly, I do not have an exact timeline as of now as to when we will start converting reservations to orders, but it will definitely be more than 30 days out! You have time so don't worry. When we do have one of our team, whether me or one of the amazing other agents, reach out to you, if it is not a good time for you to place that order or you need more time to think about it, that is totally ok! You will not lose that reservation, so take the time you need to make your decision! Cheers✨ Kathryn

It's not mildly ironic that a vehicle leveraging Canadian technology won't be available to Canadians. That sucks, and I lament its cause. I hope perhaps this state of affairs will change by the time production ensues.

Yes, I have a similar setup to recharge my EV - EcoFlow 3kW w/ solar panels.

Might take a couple of days on L1 to recharge my Ford EV, but at least if the grid fails and gas pumps stop running or out of fuel, my EV will still run.

Wish these solar battery companies come out with a 240V output so that I can get a decent charge rate on my EV.

 

[metroshot]

......... for faster AC charging, giving the possibility of sucking in 19 kW, ......

The only issue that might arise with some owners is the 100A breakers you would have to add in order to get 19kW (80A) to the battery using L2 (240V AC) in the panel.

My current EV charger at home is a L2 48A (11kW) w/ 60A breakers - that was a tight squeeze and now maxed out on my 200A service.

Electrician installing dual 60A breakers:

If I wanted to install a 19kW (80A) charger, I'd have to upgrade the panel to 300A service which I am not willing to do....

I find it rather interesting that on the reservation page on this forum I counted at least three from Ontario and Alberta Canada. Why accept reservations if you’re not going to fulfill them?

To pay for that 3D printer running 24/7.

That would be very expensive and require a very large circuit. Will keep an eye on it but price to install would put a lot of people out.
