This research focuses on the development and optimization of a load isolation type oil-electric hybrid power system for power equipment applications. The system incorporates a central controller that facilitates communication between various components, including a fuel engine connected to a generator. An adjustable switch configuration, consisting of first, second, third, and fourth adjusting switches, is employed for efficient power management. The system also integrates multiple energy storage battery sets and an electric energy output control device. Two battery set management systems ensure effective monitoring and control of the energy storage batteries. The load isolation type oil-electric hybrid power system demonstrates a simple structure, theoretical reliability, safety, cost-effectiveness, prolonged battery service life, high energy recycling efficiency, and environmental friendliness.
