Introduction to JP 40 Pack Testing
Objective: The presenter demonstrates the testing of a custom-built JP 40 battery pack designed for high-amperage loads, potentially for use in aircraft.
Specifications:
Configuration: 6S 2P (6 cells in series, 2 parallel).
Load Capacity: Over 100 amps.
Build Technique: Copper-nickel sandwich with 0.2 copper and 0.15 pure nickel.
Testing Setup and Equipment
Battery Monitoring:
Probe to measure temperature.
Fluke current meter for amperage tracking.
Load Details:
24V inverter rated at 1500 watts.
Additional load tester pulling 15 amps.
Combined loads aiming for an 80-amp draw.
Safety and Features:
BMS cable integrated but no active BMS.
Focus on pack endurance under continuous heavy load.
Testing Procedure
Initial Setup:
The heaviest load (heat gun) is turned on first.
Incremental activation of equipment to reach target amp loads.
Observations:
Current consistently peaks around 77-79 amps.
Temperatures remain stable, showing high efficiency in the pack’s design.
Voltage monitoring ensures all cells remain within safe operational limits.
Pack Performance:
The pack shows excellent thermal management.
Voltage stabilizes at around 20.5V as load increases.
Conclusion and Results
Performance Highlights:
The pack operates effectively under heavy load conditions, maintaining manageable temperatures (~55°C).
Sustained performance demonstrates reliability and robust design.
