GOAL: Measure Resistance of current-pack with more-precision for pack characterization. Module to Module, Cell to Terminal Busbar
Test set-up:
Range: up to 1 micro-meter
Test Set-Up:
Pass high (known) current and measure voltage drop - have known shunt resistors so we can use that to ensure current measurement is accurate
For measuring resistance in-between pack: measure resistance of pack, and subtract the resistance of the cells - source a measure unit from school labs
To-dos: create a set-up for measuring very-accurate low-voltage readings
Battery Impedance Meter - more detailed behavior, AC (not needed)
DC determines real-life behaviors whereas AC is a standardize-way of comparing between-cells
