Abstract
Description
Technical field:
[0001] The invention belongs to the technical field of energy and power equipment, and relates to a load-isolated hybrid pure electric drive device, which realizes complete decoupling and isolation of an engine, a power battery and an energy storage battery through a novel three-port power circuit structure. Background technique:
[0002] The basic purpose of the three kinds of gasoline-electric hybrids in series, parallel and hybrid is to optimize the working status of different energy supply devices by redistributing the power requirements of the vehicle, so that each energy supply device can work as best as possible. To achieve the optimization of energy conversion or energy output efficiency, emission, life, cost, reliability and other performance. Practice has proved that through the redistribution design of the vehicle power demand using the gasoline-electric hybrid technology, the engine is controlled at the most suitable steady-state working conditio...
