32CH Lithium Cell Grading Machine 6V 200A Ni MH Hybrid Battery Cell Tester

6V 200A 32 Channels Battery Life Cycle Tester For Li-ion/Lead-acid/Ni-Cd/Ni-MH Battery

Product Description

ACEY-HRCDS-6V200A-32CH battery life cycle tester is designed for battery cycle life testing and quality control in both production and laboratory environments. It is applicable to a wide range of battery chemistries, including Lithium-ion, Lead-acid, Nickel-Cadmium (Ni-Cd), and Nickel-Metal Hydride (Ni-MH) batteries. The system supports comprehensive test functions such as cycle life testing, capacity testing, charge and discharge performance evaluation, charge retention testing, charge/discharge efficiency testing, overcharge and over-discharge tolerance testing, pulse testing, and simulated working condition tests, providing reliable data for battery performance assessment and verification.

Equipment Features

• Current supports multiple ranges: 0.02A-50A (accuracy ≤0.03%FS), 50A-100A (accuracy ≤0.03%FS), 100A-200A (accuracy ≤0.03%FS).
• Minimum discharge voltage -6V.
• High Reliability and Low Noise: Compact and flexible for laboratory use, with high energy density.
• Energy Feedback (Up to 75% Grid Efficiency): Bi-directional energy feedback during charge and discharge reduces electricity costs and air-conditioning expenses caused by heat dissipation.
• Fixture Contact Impedance Monitoring: Prevents safety issues due to poor terminal contact or oxidation from prolonged use.
• CCCV Charging: Smooth CCCV transition with no voltage or current spikes, effectively preventing localized heating, tab delamination, micro-short circuits, and unwanted protection triggers on PCBs.
• Stable and Accurate Current/Voltage Sampling: Uses high-precision, wide-dynamic-range ADC units for long-term measurement stability and accuracy.

• Dynamic Load (DL) Protection: Safeguards batteries during charge/discharge, preventing arcing or current surges caused by loose connectors, and protects sensitive electronic components such as MOSFETs and fuses.

• Voltage Clamping Function: Limits voltage during battery protection activation or device abnormality to prevent damage to the battery or battery protection board.

• ECD & EVD Protection: Prevents charging or discharging of batteries that fail selection criteria, avoiding unnecessary protection triggers.

• Third-Party Equipment Control: Supports integration with external devices (e.g., thermal chambers) during testing; relevant test data is stored together for comprehensive battery testing (optional, third-party protocol required).

• Capacity Calibration Function: Sets the discharge capacity of a specific test step as a reference for current and capacity evaluation in various cycle tests.

• RSOC Capacity Recharge Testing: Uses the previous cycle’s charge/discharge capacity (or accumulated capacity from multiple steps) as the baseline for subsequent step evaluation.
