A Lesson in Balancing
In late August I was checking my BMS and found that my battery had fallen out of balance. I chronicled the process of bringing it back along with some thoughts on a root cause and some hard data here.
The Charging Stand
I wanted an easy way to store and charge YT. Requirements:
- Minimal floor space
- Charger can easily mount to stand, but can also be easily removed for travel charging
- No metal on metal contact
- Board is positioned so that charging port is easily accessible
- Brake light fixture is protected from contact
- Addition of spare (at a later time) will not impact the fit
- Could balance well on its own as well as when loaded
- Remote storage
I toyed around with different designs, eventually landing on a design using:
- 2x2 wood pieces
- Sunk holes to ensure no metal extended beyond the wood
- Vinyl covered eye bolts (bent) with heat shrink on the bolt ends
- 1/4" hardware for affixing the wood pieces to each other
- Wood spools with spacers to affix the DC charger to the stand
- S-hook for Remote storage
- Soft pads to protect the floor and wall
Here’s the design:
And here’s the finished product:
Changed
Nothing
Complete
The charging stand and balancing knowledge, as mentioned above.
Still need a spare…
You can check my thoughts from previous postings above, but I still need to get that spare hub in place.
What’s Next
- Helmet light- I have a great idea here, working out the details now and will get back here to post more info soon.
- Get spare hub and build as a quick swap spare
- VESC: Bump absolute max and battery regen as per the note from @rusins above
- VESC: Add additional low speed torque
- Tear down, sand, and paint
- Regrip
Research
- VESC: Add additional low speed torque
