400kw over 800V is 500amps. That’s within the adapter’s 500amp limit spec. If they want to be really careful, they could “de-rate” to 450amps for 360kw.
Yes, but my point is that with 800V, when charging at 240kw, a customer wouldn’t have to run the risk of going over the 500A limit, or frying their adapter, at all.
If the iX3 were charging at 240kw speed on a 800V connection, the battery pack would be considerably cooler than this. And, any adapter wouldn’t be running the risk of going over 500amps (or even close to burning a pin), since it would only be pulling 300 amps.
I’ve swapped mine to the ohmmu sodium after I got a warning. Luckily, the RIDE menu was enough to clear out the error code.
It seems enough people have gone with the ohmmu to know it works. It’s supposed to last 3x as long as the oem agm ones. So I’m hoping I don’t have to replace them again...
The battery pack is a lot more than just the cells. The copper or aluminum connections between all the cells make up a lot of heat too. If the heat can be dissipated easily, then Rivian should have done so from day one, and so should every EV battery pack manufacturer. But there is a limit based...
Most fun to least fun:
1. 2024 Mazda Miata (ND3), manual
2. 2023 Rivian R1T (mostly bc of its versatility)
3. 2004 BMW 330 (e46) manual
4. 2018 Tesla Model 3
5. 2025 Rivian R1S
6. 2015 BMW x5
7. 2021 Tesla Model Y
8. 2022 Tesla Model S
In terms of reliability, most to least:
1. Mazda Miata

Rivian refused to discount my batteries and wanted to charge full price of $800+. Even after I told them others were getting a discount to $500.
It pissed me off. I got the sodium ohmmu batteries along with battery monitor. I replaced the 12V myself. The sodium batteries are supposed to last 3x...
