Product Description

70V Battery Tester - Lithium Battery Charge and Discharge Machine

Professional battery pack charge-discharge testing equipment designed for evaluating performance, capacity, efficiency, and cycle life of lithium battery packs under controlled laboratory conditions.

Testing Capabilities

Test Objectives

Measure actual capacity versus rated capacity
Determine charge/discharge efficiency (Coulombic efficiency)
Assess cycle life degradation over time
Verify thermal management performance
Identify voltage and capacity inconsistencies between cells

Standard Testing 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 (0.5C, 1C) to cutoff voltage
Cycle Testing: Repeated charge-discharge cycles (500+ cycles) with periodic capacity checks
