ROI Calculation Logic

For a company manufacturing 100,000 automotive devices annually, extending the battery replacement cycle by an average of 1 year through this technology. Assuming a battery replacement cost of $8.00/unit (AI est.), the potential annual cost savings would be 100,000 units × $8.00/unit = $800K (AI est.). This significantly reduces product Life Cycle Costs (LCC).

Speed to Market
6× faster than in-house development
This technology is based on a clear operating principle of current path control via physical connector attachment/detachment, with its basic design already established. The enclosure structure and connector placement described in the patent claims can be integrated relatively easily into existing power supply designs. It does not require new chemical reactions or complex control algorithm development, and can be adopted without significant changes to existing manufacturing processes or supply chains, thus significantly shortening time-to-market compared to in-house development.
