Battery-Integrated Mobile Cases
16 patents in this list
Updated:
Mobile device cases with integrated batteries face increasing demands on power capacity, charging speed, and form factor. Current solutions typically add 3000-5000mAh of capacity while adding 8-12mm of thickness, creating a direct tradeoff between power availability and device ergonomics. Heat management during wireless charging presents additional challenges, with surface temperatures sometimes exceeding 40°C.
The fundamental challenge lies in maximizing power capacity and charging capabilities while maintaining case thickness, weight, and thermal characteristics within acceptable limits for daily use.
This page brings together solutions from recent research—including wireless charging architectures with improved thermal management, modular battery designs that allow capacity customization, multi-device charging cases, and smart power management systems. These and other approaches focus on practical implementations that balance power delivery with user experience requirements.
