The invention discloses a vehicle hybrid energy storage system based on lithium battery life prediction, which comprises a hydrogen-oxygen fuel cell used for generating electric energy. An air compressor is connected with a hydrogen-oxygen fuel cell for providing high-pressure air for the air compressor; an air storage tank is connected with the outlet end of the air compressor, the air storage tank is used for enabling the pressure of the outlet of the air compressor to be greater than the air pressure required by the hydrogen-oxygen fuel cell, and the air storage tank is also used for communicating with the air outlet of the air compressor when the pressure is lower than a first pressure value; a vacuum power assisting device is communicated with the air storage tank; an energy recovery device is used for recovering energy and converting the recovered energy into electric energy; a lithium battery is electrically connected with the energy recovery device and the hydrogen-oxygen fuel cell; and a lithium battery is used for storing energy recovered by the energy recovery device. Energy can be recovered, so that the energy utilization rate is improved.
Description
technical field [0001] The invention relates to a vehicle hybrid energy storage system based on lithium battery life prediction, in particular to a vehicle hybrid energy storage system based on lithium battery life prediction. Background technique [0002] Hydrogen-oxygen fuel cell vehicles, as the cleanest vehicles, are gradually being valued and started to be used in practice. [0003] Because the hydrogen-oxygen fuel cell is a device that generates electricity, not a device that repeatedly charges and discharges. When in use, the hydrogen-oxygen fuel cell can only generate electricity when it is working. In normal use, the amount of electrical energy output can be controlled by controlling the intake of hydrogen and oxygen. Since hydrogen is stored in tanks, oxygen is supplied to the hydrogen-oxygen fuel cell by compressing fresh air through an air compressor. [0004] When the hydrogen-oxygen fuel cell is started, the air compressor must be rotated first to compress t...
