Abstract

The invention relates to an electric oil pump energy supply system of an engine, and relates to the technical field of vehicle energy saving. The system comprises a first energy supply module, a second energy supply module and a control module; the first energy supply module comprises a first energy supply assembly and a first switch K1. The second energy supply module comprises a second energy supply assembly and a second switch K2; the first energy supply assembly comprises a first branch and a second branch. A battery energy supply unit and a third switch K3 are arranged on the first branch; the second branch is provided with a thermoelectric conversion energy supply unit and a fourth switch K4; the control module is used for monitoring operation parameters of the oil pump module, the battery energy supply unit and the thermoelectric conversion energy supply unit, and energy distribution and management among all the modules are achieved by adjusting the switching of the first switchK1, the second switch K2, the third switch K3 and the fourth switch K4. According to the electric oil pump energy supply system, the problems that in the process of supplying power to the electric oil pump of the engine, the oil consumption of the whole vehicle is too large, and energy utilization is insufficient are solved.

Description

technical field [0001] The present application relates to the technical field of vehicle energy saving, in particular to an electric oil pump energy supply system for an engine. Background technique [0002] At present, the public pays more and more attention to the protection of the environment, and the requirements for vehicle emissions are becoming more and more stringent. From the perspective of energy security, the current oil consumption for vehicles has accounted for 60% of the total oil consumption. Cars are still commercial vehicles, and the production of more fuel-efficient electric vehicles has become an inevitable choice in the future. [0003] In related technologies, some complete vehicles and some accessories of the engine need to consume engine crankshaft work to maintain operation. If the oil pump of a heavy truck engine is completely driven by the crankshaft through the cam, the crankshaft work consumed by the oil pump of a 13L diesel engine is about 1.2 ki...
