Celltester BCTer-Series
The Wattical battery cell testers offer the ability to precisely analyze battery technologies such as lead-acid, Li-ion, and their derivatives, as well as next-generation battery systems. Using advanced microprocessor-controlled controllers, they adapt to evolving battery testing needs, supporting nearly any test standard.
With an AC/DC converter on the mains side (AFE) and a DC/DC converter on the battery side, our cell tester ensures efficient, eco-friendly operation through bidirectional energy recovery.
Testing and Integration Features:
- Cells can be tested in temperature-controlled climatic cabinets, integrated into the battery test system.
- Measurement data acquisition devices and data loggers can be integrated.
- Wattical systems allow cloud-based data management and archiving.
- Integration into a Manufacturing Execution System (MES) is available.
- Built-in high-performance computer enables offline, self-sufficient operation without a host computer.
Performance and Measurement Capabilities:
- High measurement accuracy, with voltages up to 20V DC and currents from 60A to 1200A DC and a parallel-switching option of up to 5000A DC+.
- Very high measurement rates, with an option for ultra-high rate recording.
- Circuits can be connected in parallel without loss, ensuring unrestricted data acquisition.
- Adaptive range switching allows for precise measurement without manual hardware adjustments.
Customization and Flexibility:
- Modular design allows flexible configuration and customization to meet specific needs.
