Embodiment approach

[0024] Solution 1: Each power source supplies power to the load independently. At night, in rainy weather or in case of failure, if a generator stops working, the remaining generators can supply power to the load individually or simultaneously. The structure of multiple input sources greatly improves the reliability of power supply.

[0025] Solution 2: Multiple power sources supply power to the load at the same time. Under most normal working conditions, the device can realize multiple power sources supplying power to the load at the same time. In this way, waste heat and solar energy can be fully utilized to provide sufficient electric energy for the car, and the excess electric energy will be stored by charging the battery.

Abstract

The invention relates to an auxiliary power supply device of a hybrid-power electric vehicle based on waste heat and photovoltaic generation. The device mainly comprises a solar panel, a thermoelectric generator, an energy adjusting circuit and a storage battery. The solar panel is capable of utilizing solar energy to generate electric power; the thermoelectric generator is capable of utilizing waste heat produced by a vehicle to generate electric power; and the energy adjusting circuit supplies power for a load or the battery by connecting a plurality of input power sources through a multi-input converter. The invention has simple structure and high reliability, can greatly improve the fuel efficiency of the vehicle, reduce the exhaust emission, and generate great economic and social benefits.

Description

technical field [0001] The invention relates to an auxiliary power supply device for a hybrid electric vehicle based on waste heat and photovoltaic power generation, and belongs to the field of vehicle power supplies. Background technique [0002] As the world's crude oil consumption continues to increase and environmental problems become increasingly prominent, energy saving and the development and utilization of renewable energy are showing a trend of accelerated development. Automobiles are currently the main product that consumes crude oil. With the rapid growth of the national economy, the number of automobiles in our country is also increasing rapidly. Only 25% of the combustion energy of a typical automotive internal combustion engine is used to drive the vehicle, and about 40% of the energy is wasted in the form of heat. According to the Seebeck effect, thermoelectric materials can directly convert thermal energy into electrical energy. On the other hand, solar ene...
