laboratoryportableAC

The UHV-220/30CFK is a battery charge and discharge tester for battery packs, combining adjustable wide voltage ranges, configurable current stages, wireless per-cell monitoring and dual‑CPU safety architecture for laboratory and production testing.

Key features:

• Continuously adjustable voltage ranges (configurable for 10–300 V or 10–600 V) to support multi‑grade battery pack testing.
• Integrated functions: charge, discharge, cell detection, online monitoring and activation in a single unit.
• Wireless cell monitoring modules: up to 12 cells per module for simultaneous per‑cell data capture.
• PC analysis software (Chinese UI) with remote discharge control and USB data export.
• Local data storage: 2 GB internal memory for extended test logging.
• Dual‑CPU architecture to separate measurement and safety control.
• Flexible test control: modify parameters or pause tests temporarily without terminating ongoing cycles; auto‑stop triggers by voltage, time or capacity.

Technical advantages:

• Comprehensive voltage coverage (10–600 V) for diverse battery-pack configurations.
• All‑in‑one bench or production solution reducing auxiliary equipment needs.
• Per‑cell wireless monitoring enabling detailed cell-level analysis and fault detection.
• Robust safety and measurement reliability through CPU redundancy and isolation tests.
• Flexible operation modes: single unit, multi-unit simultaneous operation, remote control and status monitoring.
