Problems solved by technology

At present, the construction of charging infrastructure in the country is not perfect, and it is impossible to require electric vehicles to uniformly use charging piles for charging; therefore, most electric vehicles can only be charged using the household power grid. Due to the limitation of the power consumption of the household grid, charging The current is small and the charging time is too long

Embodiment Construction

[0023] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] see figure 1 It is a schematic structural diagram of the charging system of the present invention. The charging system in the charging method of the electric vehicle of the present invention includes: a vehicle controller, a battery management control module, an on-board charger, and a charging mode detection circuit (see the attached image 3 ).

[0025] CAN communication is used for information exchange among the vehicle controller, battery management control module and on-board charger.

[0026] The vehicle controller determines whether the external charging connection device is fully connected according to the charging mode detection circuit, which charging mode the electric vehicle enters, that is, detects whether the charging socket of the vehicle charger is connected to the charging plug of the charging pile or the cha...

Abstract

The invention relates to an electric automobile charging system, which supports charging with a charging pile and a household 220V alternating-current power supply simultaneously. An entire automobile controller, a battery management control module and an automobile-mounted charger perform information interaction through a CAN (Controller Area Network) bus. The entire automobile controller is used for confirming connection between a charging wire and an external charging device of the automobile-mounted charger, selecting a charging mode for charging the electric automobile with the charging pile or the household 220V alternating-current power supply, and controlling the charging process.

Description

technical field [0001] The invention belongs to the field of electric vehicle control, and in particular relates to a slow charging method for simultaneously supporting charging at a charging pile and a household power grid. Background technique [0002] With the depletion of global oil resources and the increasing emission requirements, electric vehicles, which are more economical and environmentally friendly than conventional vehicles, have become the design focus of major automobile manufacturers. In order to meet the longer sustainable driving requirements of electric vehicles, it is required that electric vehicles can be supplemented with power anytime and anywhere. At present, the construction of charging infrastructure in the country is not perfect, and it is impossible to require electric vehicles to uniformly use charging piles for charging; therefore, most electric vehicles can only be charged using the household power grid. Due to the limitation of the power consu...
