70 V Battery Tester Lithium Battery Pack Charger And Discharge Aging Machine

Here’s a professional English description for battery pack charge-discharge testing:

​​Battery Pack Charge-Discharge Testing​​
Charge-discharge testing evaluates the performance, capacity, efficiency, and cycle life of battery packs under controlled conditions. Key parameters include:

1. ​​Test Objectives​​

   • Measure actual capacity vs. rated capacity
   • Determine charge/discharge efficiency (Coulombic efficiency)
   • Assess cycle life degradation
   • Verify thermal management performance
   • Identify voltage/capacity inconsistencies between cells

2. ​​Standard Procedures​​

   • Constant Current-Constant Voltage (CC-CV) Charging:
     Charging at rated current until reaching cutoff voltage, then maintaining voltage while current tapers.
   • Discharge Protocols:
     Conducted at specified C-rates (e.g., 0.5C, 1C) to cutoff voltage.
   • Cycle Testing:
     Repeated charge-discharge cycles (e.g., 500+ cycles) with periodic capacity checks.
