Actually fits the pattern. they get an idea in their head, feel its plausible and post here. Get challenged, do some research finding they have nothing to talk about.

Too bad Nissan didn't invest as much energy into designing a robust pack as they did designing a secure one...alozzy wrote:For 40 kWh or higher packs, I think mux's CANBUS bridge would be the solution for getting those to work in an older LEAF (other than the challenges of different connectors, physical wiring differences, etc):

From what I can tell the turtle and final cutoff is voltage dependent, as is charging cutoff. So theoretically it should give you the range of a 30/40kWh or other battery. Whether or not the car will understand what is going on and display the correct range on the dash is another story. There's also a chance that if watt-hours are way more than the original design that it might throw some sort of error code since the car won't understand why voltage is so high even after so much juice has been used. But if this is a problem we do know that there is an easy workaround. Just feed electricity in after the place where amperage is measured. Even if you use 40kWh cells or whatever you should be able to make a parallel circuit around that part. Just add whatever shunt resistors you need to get the right percent of amperage through that part.Oilpan4 wrote:I thought that was their original plan.
Take a 24kwh pack, gut it, repack it with 40kwh pack modules. Or wire up a 40kwh battery with 24kwh battery guts.
Yeah it looked like swapping the 24kwh stuff over to the 40kwh battery was the way to go.
But if simply swapping a pack, vcm or bms would work, might as well try it and confirm or rule it out for sure one way or the other (like he did when putting a 30kwh pack and 30kwh cars' vcm in a 2011 last year and got it to work) .
I would call going 217 km with a 40kwh pack before going turtle a success.
I'm not sure how he will convince the gen 1 pack that it has more than the standard 24kwh stuff available for power.
It looked like in that last test on part 2 it displayed range with the 40kwh pack, but it looked like 24kwh range?
If the car was given 40kwh batteries wired up with 24kwh battery electronics and showed range wouldn't the car eventually learn that it has much more range than normal?
