These chemistries provide high energy density and low internal resistance, making them ideal for digital and portable medical applications.
Note: Medical-grade lithium batteries must comply with strict safety standards such as IEC 60601, ANSI/AAMI ES 60601-1, and UL 2054. These standards protect both patients and healthcare staff.
You must also consider regulatory requirements. The EU Battery Regulation 2023/1542 and UN38.3 recommendations require rigorous testing and certification for batteries in medical devices. Custom bms solutions help you meet these standards by integrating protection circuit modules, cell balancing, and real-time communication protocols.
1.3 Energy Requirements
Medical devices demand precise energy management. Custom bms solutions are tailored to meet the voltage, current, and thermal needs of each device. You benefit from protection against overcharging, over-discharging, short circuits, and thermal runaway. Balancing features extend battery life, while state-of-charge and state-of-health estimation provide accurate battery status.
Battery Type | Nominal Voltage | Specific Energy (Wh/kg) |

Part 2: SoC and SoH Reporting in Custom Lithium Battery Packs
2.1 SoC and SoH Metrics
Accurate estimation of state of charge and state of health is essential for optimizing battery lifespan and device reliability in medical environments. You rely on precise SoC data to understand how much usable energy remains in your custom lithium battery packs. The most reliable method calculates SoC using the formula SOC = 1 – Qm/QD, which relates discharge time and battery voltage. This approach provides consistent results across lithium-ion, lithium-polymer, and LiFePO4 chemistries.
For SoH, expansion force analysis has emerged as a leading technique. You benefit from full-field surface stress profiling, which integrates deformation across the battery interface. This method offers superior noise immunity and captures cumulative degradation, giving you a clearer picture of battery aging. Model-based and data-driven approaches also support SoH estimation, using mathematical models and feature datasets to map battery health over time.
