[0003] The purpose of the utility model is to overcome the shortcomings of the prior art. The range-extended diesel generator set can supply energy to the motor through intelligent power generation. At this time, the diesel engine can optimize fuel consumption and emissions under low-load conditions through intelligent control, so as to achieve the purpose of reducing the use cost. In addition, the operating compliance point of the engine is higher, the emissions are better, and it is not easy to cause DPF blockage, further reducing the use cost.

The range extender is started by reverse power supply from the battery pack, and a part of the high-voltage direct current generated by the start is used by the load, and the other part is stored through the battery pack. The battery pack receives fast charging from the commercial power in the static state of the equipment.

[0005] In the integrated system of the range-extended diesel generator set of the utility model, the range extender is composed of an engine, a generator, and an electronic control. The range extender also includes an engine cooling system, an intake system, an exhaust system, and a generator and electronic control cooling system. The high-voltage power supply system includes a generator, a motor controller, a 540V battery pack, a distribution box, a battery pack thermal management system, a DC540V line, and fast charging.

The integrated system includes an integrated frame, a range extender suspension and bracket, a heat dissipation antifreeze pipeline, shock absorption of heat dissipation system components, and a DC540V power supply line.

[0006] In the integrated system of the range-extended diesel generator set of the utility model, the engine cooling system includes an engine radiator. The front end of the engine radiator is a motor radiator. An intercooler is provided between the motor radiator and the engine radiator, and an intercooler outlet air duct is provided at one end of the intercooler.

[0009] 1. Compared with the existing diesel power solution, during engineering operations, the upper-mounted operation system needs to transfer energy through the engine power take-off. The engine operates at idle speed, with poor emissions, high fuel consumption, and poor emission effects, resulting in easy blockage of the DPF and frequent replacements.

[0010] 2. The present utility model can be driven by an electric motor. The extended-range diesel generator set can generate electricity intelligently and supply energy to the electric motor. At this time, the diesel engine can optimize fuel consumption and emissions under low-load conditions through intelligent control, so as to achieve the purpose of reducing usage costs. In addition, the operating coincidence point of the engine is higher, the emissions are better, and low-load fuel consumption is not likely to cause blockage of the DPF, further reducing usage costs.

[0011] 3. When the system of the present utility model is working, the extended-range engine adjusts the power generation operating point according to the state of the battery pack and the load demand; when the battery pack has a high power level and the load demand power is low, the extended-range engine stops working, and the power is provided by the battery pack; when the battery pack has a low power level and the load demand power is low, the extended-range engine works to generate electricity, and a part of the generated power is used for load output, and the other part is used to charge the battery; when the load demand power is high, the extended-range engine and the battery pack supply power to the load simultaneously, reducing the load on the extended-range engine; enabling the extended-range engine to always operate in the optimal load range.

[0012] 4. When the load power demand changes greatly, the extended-range engine of the present utility model always operates in the optimal load range, with good power generation efficiency and lower output fuel consumption, thereby reducing usage costs; the engine speed in the optimal load range is good, not likely to cause blockage of the DPF of the diesel engine, and the emissions are better.
