Of course I wish Rivian can survive. But I really doubt. Unless Rivian can cut the cost dramatically, they cannot ramp up the volume, volume is the key for long term operation.
Say it costs 10B to develop it, if Ford sold one Lightning, the cost is 20B, if Ford can sell 200k per year for 5 years, then R&D cost per truck is $10k.
Our tier1 is 45 cents and we always charge at tier2 at 53 cents.
And yes Tesla SC (not open for other brand yet) 5 miles away is 35 cents and 16 cents after 8pm.
This is with $7500 credit. Imagine without this next year.
People just have no interest, hard to find the right charge with enough speed, battery failure, miserable resale value, and the unpredictable repare cost, no need to mention the high insurance cost and extra $100-200 registratin fee...
30A breaker for 24A charger adds 5.5 kWh per hour for 10-12 miles and 12 hours to charge 20-80%.
If you have a reliable EA around it is fine. Otherwise, consider a 60A breaker 48A charger which reduce charge time to be half.
It sounds more like software issue triggered by the charger rather than the real error.
Of course this is only my guess, but unless Lightning is using very different battery modules, MME has much less issues to my knowledge.
Hope Ford can fix all the issue soon.
If I were you, I would try 80A and wait for a while, then check every 10min. The first sign of overloading the adapter is the heat. It should warm up if the contact is not capable to handle 80A current..
My guess is it should work fine. The manufacturer of the adapter had no chance to test 80A...
