Abstract

The embodiment of the invention relates to the technical field of electric vehicles, in particular to an electric vehicle charging and discharging control system and control method based on an energyinternet mode, wherein a routing inspection module is capable of sending a prompt command to an electric vehicle to enable the electric vehicle to reach a designated energy internet site for chargingaccording to the prompt command when the remaining power value of a lead-acid battery pack module is insufficient, so that the convenience of charging can be improved, and the travel problem of the electric vehicle can be improved; a charging module is capable of stopping charging the lead-acid battery pack module and charging a lithium battery pack module when the remaining power value reaches asecond set threshold, so that overcharging of the lead-acid battery pack module can avoided, and the charging reliability can be improved; a discharging module is capable of realizing the energy supply switching between the lead-acid battery pack module and the lithium battery pack module and ensuring that the remaining power value of the lead-acid battery pack module during charging is sufficiently low, so that efficient and reliable charging and discharging of the electric vehicle can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electric vehicles, and in particular, relate to an electric vehicle charging and discharging control system and control method based on an energy Internet model. Background technique [0002] Electric vehicles, that is, electric drive vehicles, also known as electric drive vehicles, are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as the energy source, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed of the vehicle. The first electric car was manufactured in 1881. The inventor was the French engineer Gustave Truff. It was a tricycle powered by a lead-acid battery. It was driven by a DC motor. Today, electric cars Huge changes have taken place and there are many types. [0003] The energy source of the electric vehicle is...
