Power Box offers a centralized electric power and control platform for trailers, integrating an on‑board charge controller, vehicle control unit, and additional modules into a single box. The system combines a Smart Hitch sensor suite, a 120 kW motor, and a bi‑directional battery that supports 30‑minute fast charging and 25 kW off‑grid supply, enabling safe, efficient charging, motion control, and real‑time load management to improve towing capacity and vehicle performance.

Problem
Conventional trailer systems rely on separate, often incompatible components for power management, motion control, and load sensing, leading to inefficient towing, limited payload capacity, and a lack of integrated power capabilities for off‑grid use.
Solution
Power Box consolidates the on‑board charge controller, vehicle control unit, and auxiliary control modules into a single, centralized enclosure that manages charging, battery health, and motion control for electric trailers. The integrated Smart Hitch measures trailer load in real time and feeds this data to the Power Box, which uses the information to modulate a 120 kW motor for smoother acceleration and higher towing capacity. A bi‑directional high‑voltage battery provides rapid 30‑minute fast charging and can deliver up to 25 kW of off‑grid power, turning the trailer into a mobile power source that can recharge at public EV stations. The combined system optimizes safety, efficiency, and functionality, enabling trailers to operate as self‑propelled, intelligent platforms.
Target Audience
Primary customers are trailer manufacturers, RV and motorhome producers, and commercial towing operators seeking integrated electric powertrains and on‑board power capabilities.
