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 |
Validation Focus |
| Backup Duration | Can the system sustain the data-protection window after power loss? | CC / CP discharge and energy reports |
| Transient Switching | Is intervention fast enough after a Bus voltage drop? | Scenario-based test steps and transition capability |
| Dual Voltage Architecture | 48V and 800V architectures coexist | BT-2000 + PBT-2000 |
| State of Health | Is backup still reliable after aging? | SOH, cycling, DCIR |
| Communication Integration | Are BMS strategies and protection functions correct? | CAN / Modbus / SMBus |

One Software Platform: iBest
iBest provides a unified environment for creating, executing, monitoring, and analyzing BBU test procedures — reducing training effort and making test workflows easier to reuse across projects.
- Process Setup — Variable-based cutoff conditions, C-rate settings, process preview, and configurable protection limits.
- Test Modes — HPPC / DST / FUDS / Waveform / Pulse / DCIR / CP.
- Real-Time Monitoring — Live curves, scheduled pause, resume testing, and dual-layer protection.
- Data & Analysis — Reports, CSV / Excel export, dQ/dV, and SOC analysis (optional).
- System Integration — Temperature chambers, CANbus / BMS, external measurement equipment, and MES integration (optional).
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.
