Revision 1

Rationale:

The first version of the board had some odd functions with the mux switching but was fixed in a rather unsatisfactory method. It was also decided that the BMS is not really needed and that its functionalities can be transferred to this board. Revision 1 aims to manage these.

Tasks

• [ ] Fix the MUX switching
• [ ] Read up on BMS circuitry
• [ ] Figure out how to implement the BMS circuitry
• [ ] Create and test the BMS circuitry on breadboard
• [ ] Create a new schematic for the BMS and have that reviewed
• [ ] Layout new schematic and have that reviewed
• [ ] Fabricate and Validate

Status:

Validation for the MUX and E-Fuse is almost finished.

Description

Make a board that has the following:

• Power mux that can choose an input from either the BMS or GSE
  • If you want to be fancy, tie the control pin of the mux to the GSE input, so when GSE power is applied, it automatically switches to GSE power
• efuse to protect from overcurrent and shorts
• Current/power monitor
