I like what you're doing
However I am not convinced that a battery swap makes sense in the TTXGP brand of racing. I've been to all the US TTXGP events and haven't seen a venue where I think an advantage would be realized.
Now the opposite is true for another EV race with which I am involved. The kart race was 100 laps with many turns. We had about 8 kWh total battery by rule. We used split pack. During the race, swapped battery in 7 seconds
I also was involved with the Formula Lightning series back in the 90's. We were required to make battery exchange pit stops during most of the races. This was with Pb-Acid and the total on-board battery pack was about 1200 pounds. We were able to get the actual exchange time during race conditions down to about 17 seconds.
So I have some experience with battery exchange systems. Here are a couple of things I notice with your design. Containment in the vehicle should withstand crash conditions. I think this is about 8 g's. And the electric disconnect system needs to be spring loaded. It appears you use aluminum for the contacts. That will be trouble. I'd go with copper, silver or at least tin plated.
Just some of my observations. I've seen battery packs detach from vehicles during races and have seen fires result from disconnect failures
