Reliable Performance in Critical and Low-Temperature Environments
Designed to operate in extreme environments ranging from -40°C to +60°C, our lithium-ion and solid-state batteries are ideal for emergency medical equipment, portable care systems, and field diagnostics. With 23+ years of technical experience, we are trusted by global partners like Arjo, Teijin, Mindray, Yuwell, SonoScape, United Imaging to deliver dependable energy under pressure.
In the medical industry, battery technology is becoming the power source for many critical devices, ensuring stable support during critical moments. Whether it is surgical tools, patient monitoring equipment, or applications such as respiratory care and wound treatment, batteries can provide the precise, reliable and continuous power these devices need. Through innovative battery solutions, medical devices can not only operate efficiently in various environments but also enhance the quality of patient care, promoting the advancement of medical technology and the expansion of its application scope.
Customer Pain Points:
- Runtime vs. Weight Dilemma – Clinicians require devices light enough for all-day use but with enough battery life for multiple uninterrupted scans. This creates a difficult trade-off between a heavier, long-lasting battery and a lighter option that triggers “range anxiety.”
- Inconsistent Performance – Sudden battery failure during critical procedures is unacceptable. Poor cell quality can cause unexpected shutdowns, inaccurate battery readings, and a loss of clinician trust.
- Safety & Reliability Risks – In close proximity to patients, the battery must meet the highest safety standards. Poor thermal management can cause overheating, and inadequate protection circuits can damage both the battery and the device.
Solutions:
Large Power delivers more than a battery—we provide a custom-engineered, certified, and intelligent power system tailored for portable medical ultrasound (Model: 09AQ109-06T).
By controlling the entire process in our ISO 13485-certified facilities, we ensure every component is optimized for performance, safety, and long-term reliability. This eliminates supply chain fragmentation and delivers a power source as dependable as the diagnostic device itself.
Customer Pain Points:
- Weight vs. Runtime Conflict – Devices must be light enough for all-day carry yet powerful enough to last through long appointments or travel.
- Inconsistent Quality & Reliability – For a life-sustaining device, an unexpected shutdown can be life-threatening. Poor battery quality increases warranty claims, raises maintenance costs, and damages brand trust.
- High Total Cost of Ownership – Standard lithium-ion batteries typically last only 300–500 cycles, forcing replacements every 1–2 years and creating a financial burden.
- Complex Supply Chains – Sourcing cells, BMS, and housings separately risks delays, incompatibility, and multiple points of failure.
Solution Approach:
We supply a fully certified, custom-designed power system for POCs (Model: 01WQ0026-01T). By managing the process from cell selection to final assembly and testing, we provide OEMs with a single, optimized, and dependable power solution.
The Shift to Patient-Centric Home Healthcare
Portable Oxygen Concentrators (POCs) empower patients with respiratory insufficiency to lead active, independent lives. By filtering nitrogen from ambient air, they deliver a continuous flow of medical-grade oxygen—freeing patients from heavy, limited oxygen tanks.
However, the mobility promise of a POC depends entirely on its battery, making power design a critical challenge for OEMs.
