Client Background
The client is a medical device manufacturer producing portable oxygen concentrators (POCs) for COPD patients and long-term oxygen therapy users.
Their devices must deliver stable oxygen flow during daily activities and travel, with a strong emphasis on safety, reliability, and long runtimes.
Challenges
During early deployments, the client faced several power-related issues:
• Insufficient runtime for patients who needed oxygen support during long trips or outdoor activities.
• Concerns about thermal behavior and safety when batteries were used for many hours continuously.
• Weight and size limitations that made it difficult to integrate larger batteries without compromising portability.
• The need for a chemistry with long cycle life to reduce replacement frequency and after-sales cost for home-care providers.
Battery Solution
HIMAX ELECTRONICS supplied a family of LiFePO₄ battery packs designed specifically for portable oxygen concentrators. Available configurations included 6.4 V 5 Ah, 6.4 V 12 Ah, 12.8 V 5 Ah, 12.8 V 8 Ah, and 12.8 V 12 Ah to support different POC platforms and power levels.
LiFePO₄ chemistry was chosen for its inherent safety, stable voltage profile, and extended cycle life in medical use.
Each pack integrated a dedicated BMS with protection against overcharge, over-discharge, overcurrent, and short circuit, as well as optional fuel-gauge communication to the device.
Testing & Compliance:
• To support global deployment, the packs underwent comprehensive testing, including:
• UN38.3 transportation testing for safe logistics.
• Electrical, thermal, and cycle-life testing under continuous flow and pulse flow operating modes.
• Safety and reliability verification in line with the client’s medical device standards and regulatory requirements.
Full test reports and specifications were provided to the client’s engineering and regulatory teams.
Results & Performance
After adopting the HIMAX LiFePO₄ solutions, the client’s POCs achieved significantly longer runtimes per charge, improving patient mobility. Devices showed stable output voltage and controlled temperature during extended operation, reducing alarms and unplanned shutdowns.
Customer Benefits
End users reported greater confidence when traveling or leaving home, as the battery packs provided dependable oxygen support over longer periods.
The client and its distributors saw fewer battery-related service calls and replacements, helping reduce total cost of ownership for home-care providers.
Why HIMAX ELECTRONICS
• Proven experience with LiFePO₄ systems in medical and industrial applications.
• Flexible voltage and capacity options supporting multiple POC product platforms.
• Strong engineering collaboration from pack design to validation and long-term supply.
