Gasoline-electric hybrid operating system of truck crane, and crane

A gasoline-electric hybrid operating system of a truck crane, comprising an engine, an all-in-one controller, a power battery, a battery management system (BMS) used for controlling charge and discharge of the power battery and detecting a state of charge of the power battery, and a range extending mechanism;

• the power battery is connected to the BMS, and the BMS is connected to the all-in-one controller;
• the all-in-one controller is connected to a high-voltage slip ring of a central revolving body, the high-voltage slip ring of the central revolving body is connected to a first motor controller used for controlling operation of an upper body, and the all-in-one controller is connected to a third motor controller used for controlling operation of outriggers on a lower body;
• the range extending mechanism comprises an integrated starter generator (ISG) and a second motor controller used for controlling the ISG;
• the ISG is connected to the second motor controller, and the second motor controller is connected to the all-in-one controller;
• an output end of a crankshaft of the engine is connected to the ISG, and an output end of the ISG is connected to a clutch of a truck crane.
