1. One Device Covers All Specifications: Significantly Reduced Costs

Industry Status Quo: Third-party testing agencies and manufacturers often deal with a wide variety of equipment specifications and models requiring testing. Different specifications of charge-discharge testers typically require matching with various calibration devices, resulting in substantial hardware asset investments and high management costs.

Hangzhi Solution: Multi-purpose functionality in a single unit. The PIU2000D covers a current range of 1A to 2000A and a voltage range of 1V to 2000V, maintaining a full-scale reading accuracy of ±0.01%. A single device is compatible with the calibration of virtually all charge-discharge tester specifications, significantly reducing procurement and maintenance costs.

2. Consistent ±0.01% Reading Accuracy Across the Full Range: Precision Even at Low Currents

Industry Status Quo: Traditional equipment performs adequately in the high-current range; however, in the low-current range (1A–200A), they often rely on “range accuracy” (%RG) specifications. This leads to larger error margins and fails to meet the high-precision requirements for battery cell charge-discharge testers.

Hangzhi Solution: The PIU2000D maintains a reading accuracy of ±0.01% across its entire operating range. Whether measuring 1A or 2000A, the precision remains consistent, ensuring reliable multi-purpose utility from a single device.

3. Breaking Through the Bottleneck of High-Voltage Testing (>1000V)

Industry Status Quo: Traditional multimeters are limited to measuring voltages up to 1000V. However, modern energy storage battery testing often involves voltages approaching 2000V; consequently, traditional multimeters are no longer capable of meeting these new testing demands.

Hangzhi Solution: The PIU2000D offers a full-scale voltage range of 1V to 2000V with a reading accuracy of ±0.01%. It effectively meets the high-voltage testing requirements for energy storage batteries, providing a practical solution to a critical industry pain point.

4. Integrated Design for Simplified Operation: Enhanced Efficiency and Stability

Industry Status Quo: The traditional “shunt + multimeter” configuration offers a precision level of only 0.1 to 0.5. Furthermore, it requires manual data conversion, is prone to errors introduced by contact resistance in wiring, and suffers from stability issues caused by temperature drift—all of which result in low operational efficiency.

Hangzhi Solution: PIU2000D. Features 0.01-grade direct-reading accuracy, eliminating the need for external shunts or cumbersome calculations while effectively nullifying the influence of wiring resistance. It supports both cable-through and series connection methods and offers multiple communication interfaces—with RS232 and RS485 included as standard, and a CAN interface available as an option. Calibration results can be directly imported into test reports, thereby exponentially boosting operational efficiency and facilitating seamless system integration and automated testing.
