Photovoltaic power generation system for electric automobile

Abstract

The invention discloses a photovoltaic power generation system for n electric automobile, which is characterized in that the photovoltaic power generation system comprises a vehicle main power source, a vehicle standby power source, a photovoltaic power generation module and a power source control module, and the vehicle main power source is used for supplying power to a driving system of the electric vehicle and electric appliances in the vehicle; the vehicle standby power supply is used for supplying power to the vehicle main power supply and in-vehicle electric appliances; and the photovoltaic power generation module is installed on an outer vehicle body of the electric vehicle and used for supplying power to a vehicle standby power source. The power supply control module is respectively connected with a vehicle main power supply and a vehicle standby power supply, the power supply control module is used for monitoring the electric quantity of the vehicle main power supply and the vehicle standby power supply and calculating to obtain a main power consumption proportion value and a standby power consumption proportion value, and the power supply control module is configured with a charging strategy and a power supply adjustment strategy; the system can improve the cruising ability of the electric automobile, and can prolong the service life of the power supply.

Description

technical field [0001] The invention relates to the field of electric vehicles, and more specifically relates to a photovoltaic power generation system for electric vehicles. Background technique [0002] In recent years, the automobile industry has developed rapidly. Due to the non-polluting characteristics of electric vehicles, electric vehicles are highly sought after by people. Coupled with the strong support of the state, the development of electric vehicles has been particularly rapid, and its market share in the automotive industry has increased year by year. [0003] However, limited by the limited power capacity of the power supply, battery life has always been a shortcoming of electric vehicles. At present, the solution to the battery life problem of electric vehicles is to increase battery capacity and reduce operating power consumption to improve battery life. This solution It has reached a white-hot situation, and it is difficult to make a big improvement throu...

Problems solved by technology

[0003] However, limited by the limited power capacity of the power supply, battery life has always been a shortcoming of electric vehicles. At present, the solution to the battery life problem of electric vehicles is to increase battery capacity and reduce operating power consumption to improve battery life. This solution It has reached a white-hot situation, and it is difficult to make a big improvement through technology. Even if it can be improved, the cost will be relatively high

Moreover, the power supply needs to supply power to the drive system of the electric vehicle and various electrical appliances in the vehicle at the same time, the power supply burden is heavy, the power supply is used quickly, and the power supply needs to be frequently charged and discharged, resulting in a low service life of the power supply, and the power supply of the electric power supply is expensive, and the replacement cost of the power supply is high.
