Electrical - Build 1 - Balancing the Pack

This was a picture taken after the first day of wiring. This shows the main port for the car being wired in and also both relays.

This is some of the initial wiring for the pack rail itself where we had installed the relay and also the main port.

This is a picture of an error we found with the length of the wire. We had to reach a port that was out of the span of the wire causing us to have to solder an extension to the cable so it could be properly attached,

This is a picture of Collin adding the wire extension to the cable that was to short. This process involved cutting the original wire, stripping both sides, cutting an extension, stripping both sides of the extension, then tinning all exposed wire, and ultimately melting the solder together to create the extended wire. This was then heat shrinked to seal the connections with the extended wire.

This is a picture of the final soldering joint with the extension. As you can see in the picture it was extended by about 3 inches just to give a little bit of extra leway to allow for proper wire routing.

This is a picture of us wiring the relay into the pack rail. This was the wire that was the correct length and could reach the port correctly.

This is a picture of an error we ran into with the BMS and the hardware provided. The provided hardware was to small for the slots on the BMS due to the coating on the BMS. Due to this we used a file to enlarge the slots for all of them to fit into the assembly correctly.

This is a picture of the Lithium pack charger being mounted onto the mounting plate. This included making sure the wire runs were correct, and also installing the standoffs for the BMS to rest on.

This is a picture of the BMS and Lithium charger on the mount and installed into the main assembly. We had some troubles with the holes on the mount being to small due to the powder coat finish leading us to have to drill out the holes to enlarge them for the hardware to fit in correctly.

This is a picture of Collin working on screwing down the main assembly into the car. This involved 4 bolts getting put into the main frame and being tightened. These bolts did not have a torque spec they were just tightened till no movement was available.
