Battery pack update

batteryPack3

Ok, here is an update on the battery pack.
All the cells are welded as well as the BMS. The packs are ready for finally assembly, and packaging.
I included a couple of pictures to show the progress.

Here is a small description of the pack:
Pack
120 cells in series
Divided into 14 Subpacks

Subpack
Cells: 240 x A123 small ANR26650
Cells configuration: 8 cells in series ( 1 cell = 30 x A123 in parallel (two rows of 15)
Casing: Polycarbonate (White)
Isolator: GP03 Reinforced fiberglass (red)
BMS: 8 Cell Boards (Elithion BMS)


I should post more info after Christmas

Battery boxes arrived

Just received the 14 battery boxes. I chose to go with Polycarbonate(Lexan) because it's a plastic that is heat resistant, flame retardant, has high impact strength and high dielectric strength.
Thanks to CasboPlexiglass who made them!

I'll do another post with the details on the battery box assembly!

Ok, So it's been a while since I posted, but the project was still advancing.
I concentrated mostly on welding the batteries during the winter.
But here is a quick post and pictures on the motor fully assembled.
The motor rack was powder coated for a long durability and to avoid rust.

The assembly of the flywheel with the motor went easily, we tapped in the adapter slowly onto the motor shaft to make sure the magic distance was set perfectly. The magic distance is the distance between the edge of the flywheel to the surface where the motor mounts the transmission. It is very important that this distance is accurate because the pressure plate and the transmission piston is set to this distance.

The actual mounting of the rack onto the car was also no problem since we already checked everything without the electric motor, just a little heavier.
