This flow battery test station is a high-precision, intelligent testing platform tailored for the R&D and production testing of vanadium redox flow battery (VRFB) stacks.
Integrating power electronics control, fluid dynamics monitoring, and electrochemical analysis, it simulates the operating conditions of battery stacks under a wide range of scenarios.
Supporting full lifecycle assessment—from stack activation (0V start) to performance degradation testing—it serves as an ideal tool for VRFB stack development, quality inspection, and durability evaluation.
PRODUCT DESCRIPTION
1. 0V Startup Support
Enables stack activation from 0V, eliminating the need for an auxiliary power supply during electrolyte initialization. Continuously monitors electrolyte temperature, density, and condition to ensure optimal activity.
2. High-Precision Control
Delivers current and voltage control accuracy up to ±5% FS for reliable polarization curve and efficiency testing. Built-in multi-channel voltage scanning monitors individual cell voltages to quickly identify inconsistencies and assess flow distribution uniformity.
3. Regenerative Energy Savings
Bidirectional power conversion feeds discharge energy back to the grid with over 90% efficiency, significantly cutting energy costs during long-term cycle testing.
4. Intelligent Flow Management
Directly regulates variable frequency pumps to control flow rate or pressure according to test protocols. Real-time monitoring of flow, pressure, and temperature includes configurable alarm thresholds, and automatic activation of external cooling or heating ensures a consistent thermal environment.
5. Advanced Data Analysis
Online SOC estimation tracks electrolyte and stack charge status. AC/DC internal resistance measurement supports analysis of ohmic and mass transport polarization.
●Programmable test sequences: constant current/voltage/power charge/discharge, duty cycle simulation.
