Dui ni shuo de dui
10 kW
Good news: my PCB arrived!
It was missing a few through hole components, because I chose to solder them myself to save a little bit money.
I had to make two since it was the minimum order quantity, but that's no problem, this way I have one spare.
The first test revealed that everything worked well... except for the peltier module (which is kinda the whole point of this thing in the first place). :lol:
But lucky for me, it was an easy fix:
Second test:
Everything's working, Alleluia!
I just need to find a 10 amps fuse, the 1amp one didn't stand a chance, the Peltier modules use 6Amps at startup and settle at 4 amps after a while, it burned instantly.
Then I could finally tidy up all the wiring:
Also printed and installed the last internal plastic cover. It was a bit difficult to design, but it seems to work just fine. It features a system to push the battery forward, so that it will be compressed onto the front plate, this way the battery should be firmly secured. I still have to print this pusher part, it will fit in the recess you can see in the center. Now most of the hard work should be done on the battery box:
I then couldn't resist putting back the cover, wire everything properly, give it a test and of course take some beauty shots:
I think it looks super nice, too bad it won't be visible at all once the box will be sealed. All this time and effort and no one will ever know it :lol:
There are still lots of things to be done, but hopefully everything should start getting easier. I still have to:
-install the aerogel sheets
-sand all the box to make it super smooth before the final clear coat
-drill holes for the battery power cable
-Make sure the battery fits well and that I can pass the balancing wires to the BMS box. They might be a tad too short so it's likely I'll have to make them longer.
-Paint the BMS box
Maybe then I'll be able to reinstall everything back in the frame. I hope it'll be soon!
