Charging management method and system of electric vehicle and electric vehicle

Abstract

The embodiment of the invention discloses a charging management method and system of an electric vehicle and the electric vehicle. Through the deployment of a battery management system (BMS) and a plurality of electric vehicle communication controllers (EVCCs) connected with the BMS on the same electric vehicle, when a first charging inserted gun is connected into a first charging socket, a firstEVCC converts information sent by the first charging inserted gun to obtain first interface state information and send the first interface state information to the BMS, and a second EVCC converts information sent by a second charging inserted gun to obtain second interface state information and send the second interface state information to the BMS; and the BMS generates a target charging controlstrategy according to the first interface state information and the second interface state information, so that the first EVCC and the second EVCC control the first charging inserted gun and / or the second charging inserted gun to execute charging operation according to the target charging control strategy. Therefore, in a short time, the two charging inserted guns can be used for charging more electric quantity for the electric vehicle through the two EVCCs, the charging efficiency of electric vehicle batteries is improved, thus, the time of a user to charge the electric vehicle can be shortened, and the charging experience of the user is improved.

Description

technical field [0001] The present application relates to the technical field of charging, in particular to a charging management method and system for an electric vehicle and the electric vehicle. Background technique [0002] For electric vehicles, such as electric buses, the charging pile provided by the charging operator is used for charging. Specifically, when the electric vehicle needs to be charged, it is necessary to plug a charging gun on the charging pile into the on the charging port of the electric vehicle to be charged, and trigger the charging pile to power on the plugged charging gun to charge the electric vehicle to be charged. [0003] However, the charging process of an electric vehicle is often relatively long. Generally, the battery of an electric vehicle is charged from zero to full, and the required charging time is about 6 to 10 hours. In this way, due to the limited charging power of the electric vehicle in a short period of time, it is impossible to...

Problems solved by technology

[0003] However, the charging process of an electric vehicle is often quite long. Generally, the battery of an electric vehicle is charged from zero power to full power, and the charging time required is about 6 to 10 hours.

In this way, due to the limited charging power of the electric vehicle in a short period of time, it is impossible to charge the battery of the electric vehicle (such as an electric bus) with the large amount of electricity it needs in a short period of time, and it is impossible to meet the charging needs of users.

[0004] Therefore, using a charging gun to charge the batteries of electric vehicles, especially electric buses, has low charging efficiency, which seriously affects the charging experience of users who require high charging efficiency, which may hinder the development of electric vehicles, especially electric buses, to a certain extent. car development
