Fly Farther. Fly Smarter. Fly Safer. — Battery Validation from Cell to Pack

Reproducible | Quantifiable | Traceable UAV Battery Validation

Why CHEN TECH ELECTRIC?

As UAV missions become longer and payloads heavier, battery performance increasingly defines flight endurance, peak power capability, and operational safety. Validation must therefore go beyond static capacity measurements to cover high-rate pulses, real-world flight load profiles, environmental aging, BMS strategies, and test-process support for standards such as IEC 62133 and UN 38.3. CHEN TECH ELECTRIC provides a complete validation approach built around the BT-2000 platform, covering cells through Packs. With iBest, actual flight profiles can be converted into executable test sequences, while temperature chambers and BMS / ES / ET integration enable a reproducible, quantifiable, and traceable UAV battery validation environment.

Solution Overview

UAV Battery Test Solutions | From Cell to Pack. From cell development and compact battery Packs to medium-size, high-rate modules, CHEN TECH ELECTRIC supports RPT, HPPC, high-rate pulse testing, flight-load simulation, environmental aging, and safety-test process support — helping shorten development cycles and improve flight reliability.

Market Trends & Testing Requirements

Advances in UAV technology and evolving regulations are accelerating adoption across agriculture, logistics, environmental monitoring, and disaster response. As missions become more demanding, battery design and performance directly affect endurance, mission reliability, and flight safety. Extreme temperatures can accelerate aging and capacity loss, making standardized performance testing and dynamic load simulation essential for evaluating battery capability under real-world mission conditions.

Application-Based System Selection

Key Validation Challenges

Flight Performance & Endurance Validation

Regular Reference Performance Tests (RPT) provide a standardized way to track capacity, energy, and temperature rise under controlled charge/discharge conditions. Combined with Hybrid Pulse Power Characterization (HPPC) and flight-current load simulation, engineers can evaluate peak current during takeoff and climb, available power, and discharge behavior — building a more realistic picture of battery capability throughout the mission.

Core Test Capabilities

• RPT Reference Performance — Standardized measurement of capacity, energy, and temperature rise
• Cycle Life — Track capacity fade over repeated mission cycles
• HPPC — Evaluate available power during climb and sudden load changes
• High-Rate Pulse — Verify high C-rate output for takeoff and other peak-power events
• Flight Load Simulation — Reproduce takeoff → cruise → hover → landing profiles using Waveform / DST / FUDS / custom profiles
• DCIR / ACIR — Use internal resistance as an indicator of battery quality and aging

Platform Highlights

• Cell Platform (BT-2000 5V / MCL2) — ±0.02% F.S. accuracy, voltage resolution down to the 10 μV level, and rise time <1 ms (<5 ms above 300A)
• Pack Platform (BT-2000 60V / 100V) — 5V / 20V / 60V / 100V series, transition <5 ms, with optional channel paralleling and custom fixtures
• Recommended Selection — 60V/60A or 100A for small UAVs; 100V/300A for medium-size and high-rate applications

Environmental, BMS & Safety-Test Support

• Temperature Chamber Integration — Validate capacity, protection behavior, and aging at high and low temperatures
• BMS / Communication Testing — Verify control strategies, protection logic, and stage-transition conditions
• ES / ET Acquisition — Monitor cell-voltage differences and temperature hotspots within the Pack
• Safety-Test Process Support — Build test procedures for IEC 62133, UN 38.3, and related requirements (does not provide automatic certification)
• Shipping SOC Control — Bring SOC into the target range before shipment

Recommended Test Packages

One Software Platform: iBest

iBest provides a unified environment for creating, executing, monitoring, and analyzing UAV battery test sequences. Standardized workflows reduce training effort and make test procedures 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 — Chamber, CANbus / BMS, external measurement equipment, and MES integration (optional)

Integrated Safety by Design

Safety is built around layered protection: condition detection, protective action, event recording, and traceability. This approach helps protect operators, the battery under test, and the test environment throughout the validation process.

A typical system connects iBest on a PC with the BT-2000 charge/discharge platform and can integrate a temperature Chamber, BMS / Gas Gauge, ES-100B voltage acquisition, and ET-100B/C temperature acquisition — bringing performance, communication, and environmental validation into one test environment.
