BBU Battery Backup Module Test Solutions

From Rack-Level Backup to High-Voltage Systems — Validate Uninterrupted Power with Confidence

Reproducible | Quantifiable | Traceable BBU Validation

Why CHEN TECH ELECTRIC?

AI, cloud computing, and HPC are pushing rack power density to new levels, accelerating the shift from conventional UPS systems to rack-level Battery Backup Units (BBUs). Today, BBU validation goes far beyond confirming discharge capability. Engineers must verify backup runtime, response time after a DC bus voltage drop, stability under high-voltage and high-power conditions, and long-term State of Health (SOH). CHEN TECH ELECTRIC brings these requirements together in a dual-platform architecture: BT-2000 for low-voltage applications and PBT-2000 for high-voltage systems. Both are managed through the unified iBest software platform and can be integrated with temperature chambers, BMS communications, and ES/ET measurement modules to create a reproducible, traceable, end-to-end validation environment.

Solution Overview

One platform strategy for BBU testing from 48V to high-voltage systems. BT-2000 is optimized for 48V Core Pack applications, while PBT-2000 supports 600V, 800V, and 1000V high-voltage architectures with regenerative efficiency of up to 95%. Together, they help R&D, quality, and production teams validate backup runtime, transient switching, cycle life, SOH, and BMS interaction.

Key Validation Challenges

Challenge Engineering Question

Integrated Safety by Design

Safety is built around a layered workflow: Detection → Protective Action → Event Traceability. For high-voltage test environments, additional isolation and interlock measures can be incorporated to help protect operators, the DUT, and the test facility.

A typical system connects iBest on a PC with BT-2000 or PBT-2000 charge/discharge equipment, while integrating a temperature chamber, BMS communications, ES-100B voltage acquisition, and ET-100B/C temperature acquisition. The result is a single test environment for performance, communications, and environmental validation.

Chen Tech Enters Digital Multimeter Market, Unveils HCM-1000 High-Precision High-Current Meter

Solving Energy Storage and EV Measurement Pain Points: Automatic Range-Switching Technology Sets New Industry Standard

With the booming development of the renewable energy, electric vehicle (EV), and battery energy storage system (BESS) markets, the industry’s demand for “high-precision” and “high-current” DC measurement is experiencing explosive growth. Chen Tech, a leading global provider of power electronics testing solutions, today officially announced the launch of its brand-new “HCM-1000 High-Precision High-Current Meter”. This is not only a major technological breakthrough for Chen Tech, but it also marks the debut of its product line crossing into the digital meter field, providing the industry with more precise and secure power monitoring solutions.

Breaking Through Traditional Limitations to Directly Address Three Major High-Current Measurement Pain Points

In the past, high-current measurement environments frequently faced technological bottlenecks. Traditional shunt resistors (Shunt) or single-sensor methods often generate severe heat and power loss when handling high currents. This not only directly impacts measurement accuracy but also harbors potential safety risks. Furthermore, traditional instruments struggle to balance a “wide range” with “high precision” and lack intuitive user interfaces, resulting in low efficiency for data acquisition and equipment management.

HCM-1000 Series: Smart Switching Technology Defining a New Height in Measurement

Developed by Chen Tech to address the aforementioned pain points, the HCM-1000 Series features the following key innovative highlights, completely revolutionizing existing measurement paradigms:

  • Exceptional Measurement Accuracy and Thermal Stability: The HCM-1000 delivers industry-leading, high-precision, high-current DC measurement capabilities. It effectively overcomes errors caused by thermal loss in traditional methods, ensuring authentic and reliable data.

  • Exclusive Multi-Stage Automatic Range Switching: Equipped with advanced automatic range-switching technology, the instrument automatically shifts to the optimal measurement segment based on the current level. This perfectly solves the long-standing industry challenge of being unable to maintain low-current precision under high-current conditions.

  • Embedded Smart Touch Interface: Featuring an embedded system and an intuitive touch panel, it achieves real-time display and dynamic control. This significantly enhances operational convenience and optimizes data management efficiency, aligning with digital transformation needs.

  • Broad Industry Application: This series is specifically engineered for renewable energy grids, energy storage systems, and EV charging/discharging test environments, offering a highly practical and durable testing platform.

  • Wide Scope of Applications: It delivers superior convenience and accuracy for high-current measurement, current calibration of charging/discharging equipment, and input/output current measurement and certification for EVs or energy storage devices.

Deepening Roots in Energy Technology, Moving Toward All-Around Testing Solutions

Chen Tech stated: “The debut of the HCM-1000 Series symbolizes Chen Tech’s determination to extend its reach from battery testing equipment into the field of precision instrumentation. During this critical period of energy transition, precise data is the foundation of technological innovation. The HCM-1000 will help customers shorten verification time and enhance system safety when developing energy storage and EV battery systems.”
