Hybrid energy storage method of solar electric vehicle

Abstract

The invention relates to a hybrid energy storage method of a solar electric vehicle, and provides an electric vehicle and a production technology. The electric vehicle adopts a storage battery and supercapacitor hybrid energy storage technology, is controlled by a control system, and uses an electric vehicle power supply system as the energy, the deficiencies that when an existing electric vehicledrives up a hill and increases the speed, the power is insufficient, the driving range is short, and the service life is short are overcome. When sunlight is sufficient, through solar photovoltaic power generation, the excess electric quantity is stored and used by charging storage batteries and supercapacitors; when the uphill power and the acceleration power are insufficient, the supercapacitors are used as main auxiliary energy and the batteries are used as secondary auxiliary energy, and when downhill and deceleration are carried out, the energy is recycled in time. When the sunlight is insufficient, an energy storage element is charged; when driving is carried out, the storage batteries output at constant power, and the supercapacitors respond quickly when the power is insufficient,so that the allocation quantity of the storage batteries can be reduced, charging and discharging energy consumption can be reduced, electric vehicle performance can be optimized, and the driving range can be increased.

Description

technical field [0001] The invention relates to the field of new energy electric vehicles, in particular to a hybrid energy storage method for solar electric vehicles. Background technique [0002] Energy shortage and environmental problems are prominent in today's world. The country and people pay more and more attention to energy-saving and environmental protection products, especially the design of new energy vehicle systems. The energy used by new energy vehicles is mainly energy saving, environmental protection and emission reduction, which greatly reduces the damage to the environment and is more sustainable. Such as the application of solar energy in automobiles, but solar energy has the disadvantages of instability and discontinuity. In order to ensure its stable operation, a certain energy storage device must be configured. The single energy storage system using batteries as power generation systems has disadvantages such as low power density, low charge and discha...
