As soon as a medical device is intended to be portable, worn close to the body, or used in emergency situations, the battery—or rather, the choice of battery—becomes a key development consideration. It influences safety, size, and runtime. And yes… accordingly, the topic of batteries must be addressed early in the product development process.
In medical technology, different rules apply than for consumer products. Body-worn and implantable systems must reliably manage overheating, leakage, and mechanical stress. At the same time, they should be compact, lightweight, and operate reliably over the long term. Temperature management is also part of the equation from the very beginning. That’s why we get involved early on!
We provide support for the system design of battery and energy storage systems and determine capacity, power, and charge cycles. We always consider weight, runtime, and service life in the context of the entire device. For our customers, this means that conflicting goals become apparent earlier. As a result, decisions become clearer and late changes can be better
A key component is the battery management system. We develop functions for condition monitoring, charge and discharge management, fault detection, safety shutdowns, and temperature and aging monitoring. In addition, safety engineering. We provide support for safety architectures, risk analyses in accordance with ISO 14971 and FMEA, and protection concepts against thermal runaway. At the same time, we take regulatory requirements into account. These include electrical safety, software processes, quality processes, and documentation for approvals.
To ensure that the concept ultimately works in everyday use the way our customers want it to, we conduct thorough testing at a very early stage. We use simulations, tests, and validation, and examine aging, thermal behavior, hardware, and the behavior of the entire system. This allows us to identify weaknesses before they become costly issues in the project. This is relevant for many applications!
- For wearables
- For portable diagnostic and therapeutic systems.
- For implantable devices.
- For rehabilitation robotics,
- For exoskeletons
- For mobile field medicine.
In these areas, requirements are increasing year after year, and at the same time, as a manufacturer, you naturally want to limit development risks. When battery, safety, and system design are considered together from the very beginning, these risks can be significantly reduced—and that is exactly where we support you.
