On June 22, 2010, AFS Trinity achieved a significant milestone by securing a groundbreaking United States Patent for its Extreme Hybrid drive train. This innovative system integrates ultra-capacitors and specialized power electronics with commercially available batteries in plug-in hybrid vehicles. The patented drive train not only reduces the battery costs associated with plug-in hybrid electric vehicles but also enhances their durability, reliability, and overall affordability. This advancement marks a notable step forward in the evolution of energy storage systems for plug-in hybrid vehicles.
The plug-in hybrid propulsion system features a fast energy storage device designed to extend battery life. It allows for the charging of energy storage elements using externally supplied electricity, as well as energy generated by the engine or captured through regenerative braking. The system employs electronic switches, passive electronics, an enclosure, controller circuitry, and control algorithms to effectively manage power flow between the fuel-powered engine, battery, fast energy storage system, traction motors, charger, ancillary systems, electrical distribution system, and drive train. This comprehensive approach ensures optimal performance and efficiency while minimizing environmental impact.
