The N-Gauge Battery Charger and Power Sharing prototype is based on a TI charger design for hot-swappable battery packs. Some medical devices need redundancy and flexibility in regard to battery configuration. There is a trend with large cart-based medical systems to use a uniform scalable approach across products with various power and battery capacity requirements. This battery charger focuses on a solution that is scalable to larger battery packs and maximizes system efficiency (As medical devices need to run as long as possible for patient safety). The solution was to demo hot-swappable batteries at various voltage levels, demonstrating various battery configurations, in a system with at least 3 batteries/chargers/Output stages and to add diagnostics such as voltage, current monitoring, and battery gauging.
