Portable Dual-Battery Trailer Hitch Charging System is designed for electric vehicles such as long-haul trucks, RVs, compact EVs, and golf carts. It integrates dual battery packs, a gyro wheel, an ECVT gearbox, and a generator/alternator for mobile energy recovery. An AI module with a PID-based controller dynamically manages energy flow, field voltage, and battery switching using real-time driving data. The trailer features scalable battery capacity, a coiled charging cable, cooling fans, and a compact rooftop storage carrier. It can be configured for 36V or 48V golf carts, includes low voltage recognition, and offers a top compartment for golf club storage.
The system functions across a wide range of EV models and brands, supporting universal compatibility via standard charging input ports. It leverages kinetic energy from trailer movement and regenerative braking via wheel hub-mounted generators to maintain battery charge. Solar panels can optionally extend battery life while stationary. The AI module adapts in real-time using vehicle momentum, GPS, torque, sensors, and SOC data to optimize power output from the generator/alternator to the dual battery pack. A rooftop modular storage carrier adds utility with swappable battery bays.
In addition to EV charging, the system includes an onboard AC output panel with a pure sine wave inverter, USB ports, and power sockets for backup power during blackouts or off-grid use. It can be recharged at home using a built-in AC power cord, establishing the invention as a versatile energy platform. The system also includes a version tailored for electric golf carts, operating on 36V or 48V systems, with a modular and scalable design.
The invention addresses the need for extended-range solutions in EVs, particularly for long-haul scenarios. Traditional EVs face limitations due to fixed battery capacities and charging infrastructure availability, leading to prolonged downtime and limited route flexibility. This trailer-based charging system provides a mobile charging mechanism, generating and distributing energy dynamically while the vehicle is in motion, offering emergency and off-grid power solutions.
The system is highly marketable for electric vehicle support, residential, recreational, and industrial energy needs. It integrates seamlessly with core energy recovery systems to support a range of scenarios, such as powering appliances at remote cabins or campsites and providing electricity at job sites or during military operations. Homeowners can connect the trailer charger to household circuits for temporary power during blackouts, enhancing its utility and market appeal.
