Ah, that would work as long as you could convince the LEAF to move while charging. I don't know whatTonyWilliams wrote:<snip>The extra battery would have it's own BMS and charger.
He's going to have two soon!mitch672 wrote: the head of the company I am talking about also owns a Leaf.
Neither do I. But I'm convinced that this is the model I'll end up with.highcountryrider wrote:Ah, that would work as long as you could convince the LEAF to move while charging. I don't know whatTonyWilliams wrote:<snip>The extra battery would have it's own BMS and charger.
that might take.
This sounds like the Enginer kit. Seems like a very logical way to add battery capacity. One big question I would have is the efficiency of the battery to battery energy transfer. How well would that work?- especially since your energy draw is pretty large. Is there a safety that prevents you from drawing power off the pack and "charging" (or transferring power to it) at the same time?TonyWilliams wrote:The Prius kits use the same cascade down concept that I'm proposing... that's where I got the idea from.

I am not an expert but it was my understanding that ChaDeMo has communications protocols built in just like the J1772 system that regulate the power transfer. You would have to work within that system which means the car would be telling your battery when to supply power, hence it would act like a charger when the vehicle is stopped. For runtime parallel battery operation (charge on the go) I think you would have to bypass a number of safety systems. For one, the car won't move if it thinks something is connected to it. In other words the ChaDeMo may be a more direct connection to the main battery but it is more than just a wire going to the terminals.TonyWilliams wrote:Please enlighten me as to how the battery would know that 400 volts DC is coming from a battery in the trunk, or a ChaDeMo DC charger at 400 volts? Do you think the BMS stops working because it is receiving 400 volts?
