Eight Channel 5V 20A Lithium Ion Battery Supercapacitor Testing Equipment Battery Tester

Product Overview

This eight-channel battery testing system is designed for controlled charge, discharge, pulse, DCIR, and lifecycle evaluation of lithium-ion batteries and supercapacitors. Each channel operates independently across a 0.025V to 5V constant-voltage control range and a 0.1A to 20A output range, with up to 100W per channel. High-resolution 16-bit AD and DA conversion, four-wire sensing, and dual closed-loop constant-current and constant-voltage source architecture support dependable measurement and control.

The equipment is suited to cell development, incoming-cell qualification, formulation comparison, process validation, and endurance testing in battery R&D laboratories, supercapacitor development programs, advanced-materials research centers, and academic institutions. Flexible charge, discharge, pulse, and cycle programming allows teams to configure test profiles around the behavior and acceptance criteria of their cells.

Built for continuous laboratory operation, this system combines configurable protections, offline testing with power-loss data protection, reverse-connection protection, centralized MySQL data management, and TCP/IP communication. Fine-grained recording down to 100ms, together with scalable temperature and voltage auxiliary channels, helps teams maintain traceability when tests become long, complex, and data-intensive.

Key Features

• Eight Independently Controlled Channels: Each channel can run its own program, enabling parallel comparison of cells, materials, or test conditions without forcing every position into a common operating profile. This improves utilization for mixed R&D and validation workloads.

• 5V 20A and 100W Per-Channel Capability: A 0.1A to 20A output range and 100W maximum output power per channel support demanding charge and discharge characterization within the specified 5V voltage class. The operating envelope is suitable for lithium-ion cells and supercapacitors requiring controlled high-current evaluation.

• Precision Dual Closed-Loop Control: Constant-current and constant-voltage sources use a dual closed-loop structure. Voltage and current accuracy are specified at +/- 0.1% of FS, while voltage and current stability are also +/- 0.1% of FS for consistent programmed operation.

• Versatile Charge and Discharge Programming: The unit supports constant-current, constant-voltage, constant-current constant-voltage, and constant-power charging. Discharge programming adds constant-resistance discharge, giving researchers a practical set of modes for performance and lifecycle protocols.

• Advanced Pulse and DCIR Evaluation: Charge and discharge pulses can run in constant-current or constant-power mode, with a minimum pulse width of 500ms. A single pulse step supports 32 different pulses and continuous switching from charge to discharge; custom data-point selection supports DCIR calculation.

• Long-Duration Cycling Logic: The system supports 1 to 65535 cycles, up to 254 steps in a single cycle, and up to three nested loop levels. This provides the programming depth needed for repeated aging sequences, periodic reference checks, and conditional multi-stage testing.

• High-Speed, Traceable Data Capture: Recording operates at 10Hz with a minimum 100ms time interval, 10mV voltage interval, and 40mA current interval. Test data are centrally managed through MySQL and can be exported in EXCEL 2003, 2010, or TXT formats.

• Four-Wire Measurement Connection: Four-wire voltage and current detection sampling reduces the influence of lead resistance in measurement connections. This is particularly valuable when comparing cells at higher currents or reviewing small changes in voltage response.

• Configurable Safety Protection: Users can define upper and lower voltage limits, upper and lower current limits, capacity limits, and delay time. Auxiliary-channel protection can also be configured around temperature, voltage, and individual-cell voltage difference conditions.

• Scalable Auxiliary Monitoring: Temperature and voltage auxiliary channels can be specified as required, with up to 248 temperature auxiliary channels and up to 248 voltage auxiliary channels per test channel. This supports broader monitoring strategies for thermal behavior and cell-level voltage observation.
