Abstract

The invention relates to a series hybrid electric vehicle energy storage structure based on elastic energy storage and an energy distribution method and belongs to the technical field of hybrid electric vehicles. The problem that cost increasing and energy source waste caused by a plurality of times of battery replacement existing in an electric vehicle drive energy storage structure is solved. According to the series hybrid electric vehicle energy storage structure based on elastic energy storage and the energy distribution method, energy storage assisting is conducted through elastic energy storage, and an engine works in an efficient and low-emission area as much as possible; energy transmitting is conducted through electric energy conversion, so that a control method is simple and efficient; and meanwhile an elastic energy storage system is used as the energy storage structure, pollution of a chemical battery on the environment is avoided, the service life is longer than that of the chemical battery, and use cost of a vehicle is indirectly reduced. The series hybrid electric vehicle energy storage structure based on elastic energy storage and the energy distribution method are suitable for energy storage of the hybrid electric vehicles.

Description

technical field [0001] The invention belongs to the technical field of hybrid vehicles. Background technique [0002] The traditional hybrid vehicle uses the combination of APU and power battery as the energy storage structure of the vehicle. This structure requires a large number of batteries to meet the needs of energy storage, and with the increase of the number of charge and discharge cycles, the battery performance will be reduced by as much as If the expected requirements are not met, the traditional solution is to replace the battery for the hybrid vehicle, which increases the cost of the vehicle, and the production of the battery and the disposal of the waste battery will cause some pollution to the environment. SUMMARY OF THE INVENTION [0003] The present invention proposes a series hybrid vehicle energy storage structure based on elastic energy storage in order to solve the problems of low efficiency in the existing electric vehicle driving energy storage struct...
