The Battery Pack

I’ve been brooding over the design of the battery pack. From the beginning I’ve been planning to sacrifice the seldom needed back seat. But recently one of the guys at the club got his batteries. Wow. Three crates. They sure look like they’re going to take a lot of space.

It’s high time I stripped the rear interior and started plotting where the batteries are going to go.

The fuel tank is directly under the back seat. I’m planning to cut through this floor and utilize the fuel tank as a battery box. This will serve the cause of keeping the center of gravity as low as possible.

Having cleared out the back seat and the rear cargo area I took some measurements and plotted out a few rough battery pack designs. (For these images I’m assuming that I’ll be using the Voltronix 160ah Li batteries which are 18.2cm x 7.1cm x 29.7cm. The width of the exposed metal where the rear seat was is 92cm.) To my delight it looks like these batteries are going to fit in here without much trouble.

For the cause of weight distribution I will likely put four to six batteries in the engine compartment. In addition to carving through the floor into gas tank, I will also carve out the cargo area floor to built an inset battery box.
