50V 500A Lithium Battery Tester

Product Overview

This high-current lithium battery tester is engineered for controlled charge and discharge evaluation of large-format cells, modules, and battery assemblies within a 50 V operating envelope. Its 25 kW single-channel power capability, 500 A current range, four-wire sensing, and dual closed-loop CC-CV architecture give laboratories a stable platform for demanding electrical characterization. Independent channel control supports disciplined test execution while helping users obtain repeatable voltage, current, capacity, and resistance data.

The equipment is suited to battery R&D, incoming-cell qualification, validation laboratories, pilot-line development, and advanced materials research. It supports constant-current, constant-voltage, constant-power, and constant-resistance test modes, making it practical for cycle-life studies, rate capability evaluation, pulse characterization, and application-condition simulation. Optional auxiliary measurement extends visibility to battery surface temperature, tab temperature, and external voltage signals.

Designed for sustained laboratory operation, this system combines MOSFET power control, high-resolution measurement, rapid current response, and layered protective functions. Centralized MySQL data management, Ethernet communications, barcode traceability, and offline testing capability support reliable execution and efficient review of high-value test programs under controlled operating conditions.

Key Features

• High-Current 25 kW Test Capability: The unit provides 2.5 A to 500 A per-channel current measurement capability and 25 kW single-channel output power. This capacity supports intensive charge and discharge testing where high current and controlled power delivery are essential.

• Dual Closed-Loop CC-CV Control: Constant-current and constant-voltage sources use a dual closed-loop structure. Smooth constant-current to constant-voltage transition helps prevent current spikes and reduces large-current impact on the battery during charge termination.

• High-Resolution Electrical Measurement: Voltage and current measurement use 24-bit resolution, with voltage accuracy of +/-0.02% of FS and independent-range current accuracy of +/-0.05% of FS. Four-wire connections at the shared charge/discharge port help support dependable measurement at high current.

• Fast Dynamic Response: Current response time is <=3 ms, current transition time is <=6 ms, and the minimum process-step duration is 0.1 s. These capabilities allow the equipment to follow programmed profiles efficiently and support time-sensitive characterization tasks.

• Flexible Charge and Discharge Modes: Users can configure constant-current, constant-voltage, constant-current constant-voltage, and constant-power charging, plus constant-current, constant-voltage, constant-power, and constant-resistance discharging. Voltage, current, relative time, capacity, and -DeltaV are available as applicable cutoff conditions.

• Profile and Pulse Test Programming: Table-based editing supports operating-condition simulation with up to 1 million downloaded lines. A pulse step can contain 32 different pulses, uses a minimum 100 ms pulse width, and can continuously switch between charge and discharge within one pulse step.

• Integrated DCIR Evaluation: The system supports DCIR calculation using user-defined sampling points. This enables teams to align direct-current internal-resistance evaluation with their own pulse procedures and review resistance behavior alongside the main electrical record.

• Layered Operational Protection: Configurable software limits cover upper and lower voltage, upper and lower current, and delay time, while hardware protection includes reverse-connection, overvoltage, overcurrent, and overtemperature protection. Power-side provisions include surge, islanding, frequency, voltage, and phase-loss protections.

• Traceable Data Infrastructure: Test data can be managed centrally in a MySQL database, exported as Excel or Txt files, and reviewed through customizable plots with four Y axes. Barcode scanning supports historical-data management and traceability through the battery barcode.

• Optional Process-Synchronized Auxiliary Monitoring: Optional temperature and voltage auxiliary channels bind their measurements to the main voltage and current data. Measured temperature can also serve as a process-step control condition and a protection condition during testing.
