In medical equipment, the battery is a critical system component. Reliability, safety, and predictable behavior throughout its entire service life are essential, particularly in portable and life-critical applications. Battery solutions must therefore be an integral part of the system design and meet both technical and regulatory requirements.
Tefoo develops interchangeable hard-case smart battery packs with voltages ranging from 3.6 V to 14.4 V, intended for medical and industrial applications. The robust housings enable safe replacement, while integrated protection circuits, cell balancing, and an advanced Battery Management System (BMS) ensure controlled charging and discharging. The BMS supports functions such as accurate State-of-Charge determination, fault detection, and communication via SMBus, which simplifies system diagnostics and maintenance. Support for hot-swapping increases the availability of medical equipment during use.
In addition to functional safety, quality assurance and continuity of supply are crucial. Tefoo works in accordance with ISO 13485 and supplies battery packs that comply with IEC 62133 and UN 38.3, among others, which supports validation and certification. By designing on a platform basis, battery packs can be reused across multiple projects and product life cycles of ten years or more remain manageable.
The solutions are used in fans, patient monitors, AEDs, and portable diagnostic systems, among other things, where safety, traceability, and long-term availability are key.
