Part 1: Custom Lithium Battery Packs Benefits
1.1 Higher Energy Density
You need portable oxygen concentrators that deliver consistent performance without frequent recharging. Custom lithium battery packs offer a significant advantage in energy density compared to traditional battery technologies. This means you can store more energy in a smaller, lighter package, which is essential for medical devices.
Battery Type | Energy Density (kWh/m³) |
|---|---|
NiMH | 70 – 100 |
Lithium | 80 – 200 |
When you choose custom lithium battery packs, you benefit from both gravimetric and volumetric energy density. For medical applications, these packs typically provide:
Energy Density Type | Range (Wh/kg) | Range (Wh/L) |
|---|---|---|
Gravimetric | 150–250 | N/A |
Volumetric | N/A | 300–700 |
High energy density allows you to design compact devices that do not sacrifice runtime or performance. Lithium-ion batteries, for example, can reach up to 260 Wh/kg, making them ideal for applications where space and weight are limited. NMC Lithium battery chemistries are often chosen for their superior energy density in compact medical devices, while LiFePO4 Lithium battery chemistries provide excellent thermal stability and long cycle life.
Tip: High energy density in custom lithium battery packs means your devices can run longer between charges, supporting uninterrupted patient care.
1.2 Longer Runtime
Longer runtime is critical for portable oxygen concentrators, especially in medical environments where reliability can impact patient outcomes. Custom lithium battery packs are engineered to maximize runtime by optimizing several key factors:
Factor | Description |
|---|---|
Battery Chemistry | Most portable oxygen concentrators use lithium-ion batteries for optimal performance. |
Voltage | Matching battery voltage to device requirements ensures efficient operation. |
Capacity (mAh or Wh) | Higher capacity extends runtime but may affect weight and cost. |
Weight & Size | Larger batteries increase runtime but can reduce portability. |
Oxygen Flow Needs | Assessing daily oxygen requirements helps select the right battery pack. |
Battery Runtime | Choose batteries that deliver extended runtime for continuous support. |
Charging Speed | Fast-charging batteries minimize downtime. |
Brand Reputation | Trusted brands ensure consistent performance and safety. |
Custom lithium battery packs can provide 8–12 hours of continuous operation, depending on the device and usage. This extended runtime reduces the need for frequent battery changes or recharging, which is especially important in clinical and home care settings.
1.3 Lightweight for Portability
Portability remains a top priority for medical device manufacturers. Custom lithium battery packs help you achieve lightweight designs without compromising runtime or performance. The impact of battery weight on user experience is clear:
Weight Range (lbs) | Impact on Portability and User Experience |
|---|---|
3–20 | Lighter models enhance mobility, allowing users to maintain an active lifestyle. Heavier models may require additional support for transport. |
The lightest model, ReadyO₂ Lite, weighs only 1.32 pounds.
The heaviest model, Philips SimplyGo POC, weighs 10 pounds.
This range allows you to tailor solutions for different user needs.
High energy density batteries enable you to extend runtime without adding significant weight. This balance is crucial in medical, robotics, security, infrastructure, and consumer electronics sectors, where both portability and performance matter.
Note: Custom lithium battery packs let you design devices that are easy to carry, supporting active lifestyles and improving patient satisfaction.
1.4 Enhanced Reliability
Reliability is non-negotiable in medical devices. Custom lithium battery packs deliver enhanced reliability through advanced safety features, robust battery management systems (BMS), and strict quality controls.
Integration with strict safety and reliability standards ensures dependable operation.
LiFePO4 Lithium battery chemistries offer thermal stability and long cycle life, while NMC Lithium battery chemistries provide high energy density for compact devices.
Every battery pack includes a BMS, as required by national and international regulations.
Battery cycling tests evaluate health, state of charge, and internal impedance, ensuring consistent performance.
Nominal capacity (Ah) and detailed documentation of capacity and energy (Wh) are essential for medical compliance.
Custom lithium battery packs also feature:
Long life cycles, reducing the need for frequent replacements.
Quick charging (1–2 hours), which is vital for emergency readiness.
Lightweight construction, supporting portability and ease of use.
Feature | Description |
|---|---|
Enhanced Safety | Protection against over-charge, over-discharge, over-current, short circuits, and thermal runaway. |
Optimized Performance | Precise voltage and current control, cell balancing for maximum capacity and cycle life. |
Data Monitoring & Communication | Real-time data monitoring and system integration via CANBus, SMBus, etc. |
Multi-layer Protection Mechanisms | Redundant detection, fuses, self-recovery components, and thermal runaway protection. |
Fast Hardware Cutoff | Prevents current surges and thermal runaway. |
Software Pre-warning & Power Limiting | Limits output power or stops charging/discharging before hardware action. |
These features give you confidence in the reliability and safety of your portable oxygen concentrators. You can trust that your devices will perform consistently, even in demanding environments.
