The actual statistical data show that the actual service life of the overall battery pack is significantly lower than the bench test life of the battery cells. The structure of the predecessors has made a variety of structural schemes, including lithium battery + super capacitor, lead-acid battery + super capacitor, lithium battery + lead-acid battery, but most of them use the direct parallel connection of two energy storage devices, and practice has proved that, Direct parallel connection is difficult to achieve the desired effect. This is because the voltage platform of the two is always consistent due to direct parallel connection, and the decoupling of the working states of the two cannot be fundamentally realized, so that the simultaneous optimization of the two working conditions cannot be fully realized.

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...
