1. Client Background & Challenges

Our client designs and manufactures mobile medical carts (e.g., medication carts, telemedicine stations) for hospitals and clinics across the EU. Their challenges were uniquely critical:

1. Absolute Safety & Compliance: Any risk of battery failure—especially fire or fuming—is completely unacceptable in an oxygen-rich hospital environment. Compliance with medical device directives (MDD/MDR) is mandatory.

2. Predictable Power Decline: Nurses need accurate, predictable battery level indicators to avoid unexpected shutdowns during patient-critical procedures.

3. Long Service Life: Hospitals invest in carts for the long term (5-7 years). Batteries must last the lifespan of the equipment with minimal capacity fade.

4. Silent Operation: Batteries and charging systems must emit no audible noise to maintain a quiet healing environment.

2. Our Tailored Solution: Safety as Standard

We provided a 14.4V 3000mAh Ni-MH Battery Pack engineered for the medical sector.

1. Inherently Safe Chemistry: We championed Ni-MH technology for its zero fire risk and stable chemistry, providing the highest possible safety factor for medical use cases.

2. Linear Voltage Discharge Curve: Unlike lithium-ion, which has a flat discharge curve that can lead to sudden "cliff-edge" shutdowns, Ni-MH provides a gradual, linear, and predictable decline in voltage. This allows for a much more accurate state-of-charge (SoC) reading, giving staff ample warning to recharge.

3. Medical Grade Construction: The pack was built to withstand repeated disinfection with hospital-grade cleaning agents. All materials were selected for chemical resistance and biocompatibility.

4. Ultra-Quiet Charging: The charging protocol was optimized for silent operation, with no cooling fans required, making it ideal for charging at nurse stations without disruption.

3. Product Specifications (Highlights)

• Model Number: BAK-NH003

• Self-Discharge: <10% per month (maintains charge for reliable emergency use).

• Key Feature: Linear and predictable discharge behavior for accurate battery gauging.

• 

4. Results & Value Delivered

• Achieved Regulatory Compliance: Our battery solution was a key component in helping the client achieve CE Marking under the Medical Device Regulation (MDR).

• Eliminated Critical Failures: Hospitals reported a 100% elimination of unexpected, mid-procedure power failures since adopting the new carts.

• Became a Marketing Advantage: The "Inherently Safe Ni-MH Power System" is now a core selling point, directly addressing a key concern of hospital procurement and risk management teams.
