Speaking of battery boxes:
Remy inadvertently brought up a valid point earlier, about battery box heat
...which got me to thinking about what else, inside of the box (besides the battery), can create heat
So, after re-evaluating the situation, it seems like "physically" mounting the SC's inside of the battery box, isn't a good idea
Because they can produce a lot of heat that can/will affect the battery
...& also, that "heat" isn't good on them either
As such, they would/could benefit from not being "sealed up in a box"
...& may even benefit from some cooling
* My main goal for this battery box is to
secure the 2kWh of Lithium battery, in a steel box
...& then, secondarily to keep
all of the (HV) battery cables & connections inside of the box
One of the earliest designs of the battery box, for this application, had the SC's (still) inside of the box
...but, off to the side
...& kinda like on a shelf (above the frame rail)
So, the plan ended up evolving to just a simpler (to make) (2) piece, (4) sided box
...& mount the (2) SC's inside of the box
...& also, mount the CB right onto the front of the box
This way all of the battery cables & connections, would stay inside of "the box" (with the battery pack)
Speaking of Circuit Breakers:
Here are some ideas on CB mounting
...box mounting
...& a potential construction method
* That idea, was to have, the part of the box with the CB "butt" up against the floorboard
...in the angled down area
...& in front of the seat
This way the CB could be "flush" (& even) with the floor board (by protruding thru a hole)
...& so, easily accessible by the driver
But, "thinking it thru"
..."if" the CB was mounted "flush", with the floorboard (in front of & below the drivers seat) there seemed to be a "good" potential of "it" getting kicked during entry & exiting of the vehicle
So, it's probably NOT a good idea to have the CB "flush" with the floorboard
...& as such, "the plan" evolved to simply mounting the CB vertically (on the front of the battery box)
...& then, cutting an "access hole" in the floorboard
So, this way the CB would be safely mounted, down in a "recess" (& better protected)
...but, also, still easily accessible by the driver
Oh, yea back to the SC's
So, now I'm thinking that I can mount the SC's on an actual "shelf"
...on the chassis, right next to the battery box (but, thermically isolated)
This way the wiring from the SC's can still "feed" right into the side of the box
...where all of the cables & connections should be safe & secure
