5V 5A Lithium Ion Battery Testing Equipment Battery Tester

Product Overview

This four-channel battery testing system is designed for precise evaluation of lithium-ion cells, laboratory prototypes, and electrochemical energy-storage components. With a programmable voltage range from -5 V to +5 V and current capability up to 5 A per channel, the equipment supports controlled charge, discharge, pulse, constant-power, constant-resistance, and DCIR testing within one integrated platform.

The system serves battery R&D laboratories, cell manufacturers, materials researchers, universities, and quality-control teams. It supports routine cycling, performance verification, capacity characterization, rate testing, pulse response analysis, and development-stage validation for cylindrical, pouch, coin, and other compatible cell formats using a universal fixture.

High-resolution 16-bit AD and DA conversion, four current ranges, four-wire measurement, rapid current response, and stable output regulation help produce repeatable test results. Software protection, power-failure data protection, offline testing, and database-backed record management support dependable operation during extended test programs and demanding research schedules.

Key Features

• Four Independent Test Channels: Four device channels allow parallel testing of multiple cells or test conditions, improving laboratory throughput while maintaining channel-level control and measurement.

• Wide Dynamic Current Range: Four selectable current ranges cover 0.1 µA to 5 A, allowing the same system to address low-current electrochemical measurements and higher-current battery performance tests with appropriate resolution.

• High-Precision Voltage and Current Control: Voltage and current accuracy are both specified at ±0.02% of full scale, while stability is maintained at ±0.005% of full scale for consistent charge and discharge results.

• Fast Sampling and Current Response: Current response time is ≤100 µs from 10% to 90% or 90% to 10%. Data recording supports time intervals of at least 1 ms and continuous charge-discharge recording at 1000 Hz.

• Flexible Charge and Discharge Programming: The equipment supports constant-current, constant-current/constant-voltage, constant-voltage, constant-power, constant-power/constant-voltage, and constant-resistance charge modes, together with multiple discharge strategies.

• Pulse and DCIR Testing: Pulse testing supports constant-current charge and discharge, minimum pulse widths of 400 µs, and up to 16 different pulse segments within one pulse step. Dedicated DCIR measurement steps support dynamic resistance evaluation.

• Comprehensive Protection Controls: Configurable voltage, current, capacity, and fluctuation limits help protect test articles and equipment. The software also provides power-failure data protection and offline testing capability.

• Four-Wire Measurement Architecture: Four-wire voltage and current sensing reduces the influence of lead resistance, supporting more reliable measurements for low-voltage cells and precision characterization work.

• Structured Data and Connectivity: A MySQL database organizes test data, while 100M Ethernet communication through TCP/IP supports host-computer operation. Results can be exported in EXCEL 2003, EXCEL 2010, and TXT formats.

Applications

Technical Specifications

The four-channel architecture and programmable test modes allow laboratories to combine routine cycling with advanced transient measurements on the same platform. Researchers can define voltage, current, time, capacity, energy, power, and pulse-related cutoff conditions according to the test objective, helping reduce manual intervention and improve procedural consistency.

The current-range design is especially useful when a laboratory works with cells and materials that require significantly different test currents. Low-current measurements can use the lower ranges for sensitive characterization, while higher-power testing can use the 150mA---5000mA range. The specified range-dependent current accuracy values make the measurement capability easier to assess during method development and equipment selection.

Data recording is designed for both long-duration cycling and fast pulse events. Continuous charge-discharge operation can record at 1000Hz, while GSM pulse mode supports individual pulse recording. Time, voltage, and current recording thresholds can be configured at the stated minimum intervals, providing a detailed data trail for performance analysis, troubleshooting, and report preparation.
