5V 30A Battery Tester with Host Computer Connection

Product Overview

This system is an eight-channel battery testing platform engineered for controlled charge, discharge, cycling, pulse, and DCIR evaluation of laboratory cells. Its 5 V operating window, dual current ranges from 0.03 A to 30 A, and 150 W maximum output per channel support detailed electrical characterization across low- and higher-current test duties. Independent channel control enables multiple test profiles to run simultaneously without compromising channel-level control.

The equipment is suited to battery R&D laboratories, cell development teams, materials research groups, and quality-focused evaluation workflows that require host computer connectivity and centralized test-data management. It supports constant-current, constant-voltage, constant-power, and constant-resistance operating modes, allowing researchers to define practical protocols for charge acceptance, discharge behavior, cycle life, pulse response, and internal-resistance analysis.

Built around 16-bit AD and DA resolution, four-wire voltage and current sensing, and dual closed-loop constant-current and constant-voltage source architecture, this unit is designed for repeatable testing under demanding laboratory schedules. Configurable safety limits, reverse-connection protection, power-loss data protection, and offline testing capability help protect test continuity while maintaining disciplined control of each connected cell.

Key Features

• Independent Eight-Channel Control: Each of the eight channels operates independently, allowing different voltage, current, time, capacity, and cycling programs to run in parallel. This improves bench utilization when evaluating cells at different stages of development or under different test conditions.

• Dual-Range 30 A Current Capability: The equipment provides a 0.03 A to 6 A range and a 6 A to 30 A range on every channel. This arrangement supports controlled testing from lower-current characterization through higher-current charge and discharge procedures while retaining stated full-scale accuracy and stability.

• Precision Four-Wire Measurement: Four-wire connection for voltage and current detection reduces the influence of lead resistance on measurements. Combined with 16-bit AD and DA resolution, the system supports reliable capture of cell behavior for comparative R&D and process evaluation.

• Dual Closed-Loop Source Design: Constant-current and constant-voltage sources use a dual closed-loop structure. This architecture is intended to maintain controlled output behavior during transitions and extended test programs, supporting consistent execution of defined electrical profiles.

• Versatile Charge and Discharge Programs: Constant-current, constant-voltage, constant-current/constant-voltage, and constant-power charging are available. Constant-current, constant-power, constant-resistance, and constant-voltage discharge modes broaden the ability to match test methods to cell design and evaluation objectives.

• Pulse and DCIR Test Support: Charge and discharge pulse modes support constant-current or constant-power operation, with a minimum pulse width of 500 ms. A pulse step can include 32 different pulses and continuously change from charging to discharging; custom sampling points are supported for DCIR calculation.

• Long-Duration Cycling Control: The unit supports 1 to 65,535 cycles, up to 254 steps in a single cycle, and nesting to three levels. A per-step duration of up to 365 x 24 hours allows extended protocols to be programmed without manual intervention.

• High-Frequency Data Capture: Test data can be recorded at a minimum 100 ms interval, equivalent to 10 Hz recording frequency. Voltage and current change thresholds can also be used to capture meaningful electrical events while maintaining organized test records.

• Centralized Network Data Management: TCP/IP communication and a centrally managed MySQL database provide a structured basis for host computer-connected testing. Data can be exported in EXCEL2003, 2010, or TXT formats for downstream analysis and reporting.

• Configurable Protection and Test Continuity: The system provides programmable upper and lower voltage and current limits plus delay time, reverse-connection protection, power-loss data protection, and offline testing capability. These functions help laboratories maintain controlled operation through routine test interruptions and connection risks.
