Straight forward
Data for every-single-cell & entire pack
Current sense - pack voltage readings
Sum-up AFE readings - programmable multimeter
Reading Voltage & Current (5-6 amps - whatever cruise-current draw)
laptop inside-car to read amperage
Q: Current to discharge at?
Fraction of the capacity
Standard discharge: 1/2 amp
Data-sheet
5-6 amps (worst case 10 amps)
Aryan has a Confluence page: “Custom State of Charge”
HPPT Battery Testing - 5% + number of hours it will take
State of charge curve
UBC: 4 amp state of charge curve - open state voltage - predicting it
Battery Manufacturers - data that exists?
MS16: Capacity + Stability
Don’t care about weight for cells - going with characterization
Temperature range is smaller than other batteries
Resistance-Testing Plan Resistance-Testing Plan
Go over current confluence doc for trying to figure out how to test for very-low voltage readings
Vibrational Testing
Vibrations are a way that packs can die - internal components can become damaged
Setting up vibrational testing??
Point of reference for before/after changes are made to module and enclosure angular frequency - amplitude of wave = calculate energy
IMU - measures acceleration in-all axes - making one in-progress by Hardware
Telemetry - collects data - TBD = unknown
Vibration Pads - for modules
Mech/Elec Sync Dates
were these finalized yet? - make/put stuff in the channel
Did we also want to have weekly Firmware/Battery Syncs?
Meetings every 2 weeks for Firmware/Battery Syncs - talk to Jenna about what days would be best to meet-up
