Battery Questions
- How do you select cells?
- how do you design a protective shell?
- mounting options ingrained in the case?
- heat sensing?
- heat dissipation? how important to design for this?
- How to effectively calculate power requirements of a complex system?
- At which stage in the design cycle is the battery designed? (before/after motor selection, before/after full electrical system diagram)
- How to deal with/account for in-rush current?
- testing vs calculation
- battery placement within the system? - is this important?
- sourcing?
- Active vs Passive balancing?
- Copper wiring/Soldering
- Connectors
- Assembling the battery - how important to test each cell and specify each cells location based on resistance?
- Spot welding - worth it to make a pcb supercap thing for that?
- bms on the battery? or separated?
- hexagonal or square grid pattern?
- vertical stacking? - some one else advised against this, but it might be nice to have a flatter battery
- how to charge, with bms or without?
- What to expect during assembly?
- expected costs? cost savings?
- Other cell chemistries to consider?
- Diagnostic tests to run?
- Critical data query functions?
- Hierarchy of protections?
- Firmware Architecture? Use OOP to send commands to BMS and store data?
- Is it useful to manually trigger the FETs or allow BMS to handle it?
- Ideal calibration procedures?
- Optimal to use IC as a peripheral and have microcontroller sample it for necessary data?
- When to use FUSE functionality?
IC Specific(may not be useful)
Avoid shutdown in favour of deepsleep? Save data to OTP before shutdown?
Uses for SEALED security?
Use permanent fail to brick chip? Avoid using PF if not intending to blow fuse?
How to get the Chip to be recognized by BQstudio?
Chip's internal die temperature reliable? OR is using an external thermistor better?
