Short Description
The ReJoule BattScan050M is a non-destructive diagnostic system for rapid state-of-health (SOH) testing of lithium-ion battery modules. Combining Electrochemical Impedance Spectroscopy (EIS) and Direct Current Internal Resistance (DCIR) methods, it determines performance, degradation, and connection faults in under five minutes. The system supports End-of-Line testing in Module Manufacturing and Testing & Remanufacturing in early Recycling stages, enabling consistent quality assurance across the battery life cycle. Integrated with ReJoule’s BatteryDB cloud platform, it automates data collection, analysis, and traceability for reuse qualification and manufacturing QA.

Product Information in Detail
- The BattScan050M delivers fast, non-destructive diagnostics for lithium-ion battery modules, combining Electrochemical Impedance Spectroscopy (EIS) and Direct Current Internal Resistance (DCIR) to evaluate internal condition and performance within minutes.
- In battery module manufacturing, the BattScan050M is used at the End-of-Line stage to verify electrical integrity and production consistency before modules are integrated into packs. Operators connect modules via shielded test leads, initiate the automated EIS/DCIR sequence, and receive a complete State-of-Health (SOH) profile with >96 % accuracy. The system flags deviations such as contact resistance, open circuits, or capacity imbalance—allowing immediate process correction and traceable QA documentation.
- In reuse or recycling facilities, the same workflow identifies which retired modules are suitable for second-life applications. Modules are connected and tested without disassembly, producing a rapid grading outcome that classifies each unit by SOH, internal resistance, and stability. Results are automatically uploaded to BatteryDB, ReJoule’s cloud-based analytics platform, where they can be viewed, exported, or integrated into digital asset-tracking and battery-passport systems.
- Testing workflow: A new or used lithium-ion module (10–50 V range) is connected via terminal cables to the BattScan, and the user starts the test using the parameters defined during the calibration phase. The system also includes an input data port to read BMS data where necessary, supporting serial communication interfaces such as CANbus, RS-485, SPI, or others. For module types new to the database, ReJoule offers characterization services to establish a diagnostic reference database. If a battery type has not yet been characterized, ReJoule collaborates with clients to build up the necessary reference test data to ensure accurate SOH estimation and fault detection.
- All test data are stored and visualized in BatteryDB Cloud for traceability and reporting. SOH estimation results are always benchmarked against charge–discharge cycling, and during benchmarking, model performance metrics such as median absolute error, RMSE, R² score, and error variance are provided to objectively assess model performance.
- Operating between 10 and 50 V and up to 10 A, the BattScan050M is lightweight, portable, and can be customized for different voltage ranges or interface requirements. Variants include the BattScan450P (for battery packs up to 500 V) and the BattScan500V (for EV testing via DC fast-charge port). Future models will support voltages up to 1000 V.
