In this page, methods of keeping a battery module electrically isolated from the rest of the car will be discussed.

(Up to this point), I couldn’t find any content exactly on keeping a battery module electrically isolated. What I have found Information found about electrical isolation can be summed up with the following:

  1. Keep live wires away from locations where they can make contact with other components and/or hands

  2. Any exposed conductors should not be connected to the electrical system

  3. Keep wires from fraying/leaking

  4. In general, keep a layer of insulating material between conductors

  5. Ensure that if a metal object will not short out what you are working on if it isropped


The regulations state that for our battery module,

Here are some pieces of practical knowledge I have gathered from the MSXIV documentation

    • Hard fiber sleeves

    Disk springs made of stainless steel to keep the pieces pressed together

  • Hookup was not in contact with busbar

...

It turns out that fuse wires are very complex, and quite unnecessary for MSXIV, due to a low current draw from each battery. They are also a nightmare to spot weld.

//TODO: Ask Micah what kind of currents would justify the use of fuse wires.

The bare minimum for fuses seems to be a fuse block:

Fuse and Power Distribution Blocks
