Electric car and intelligent discharging device thereof

Abstract

The invention provides an intelligent discharging device of an electric car. The intelligent discharging device comprises an alternating current discharging port, a discharging connecting device, man-machine interaction equipment, a controller, a battery management system, a power battery and direct-current/alternating-current switching equipment. One end of the discharging connecting device is connected with the alternating current discharging port, and the other end of the discharging connecting device is connected with other electric equipment. The man-machine interaction equipment is in communication connection with the controller, and is used for setting discharging information, sending a discharging starting instruction or a discharging stopping instruction to the controller after atriggering signal is received and displaying discharging state information and reminding information. The controller is used for executing corresponding operation based on the received discharging starting instruction or discharging stopping instruction. The battery management system is used for controlling the power battery to discharge outwards or stop discharging outwards. The power battery isused for providing a direct current for an outward-discharging loop. The direct-current/alternating-current switching equipment is used for converting the direct current into an alternating current and outputting the alternating current to the alternating current discharging port. The discharging device of the electric car can be easy and convenient to operate, discharging starting and stopping can be set in intelligence and individuation modes, and information intelligent reminding can be conducted in the discharging process.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to an electric automobile and an intelligent discharge device thereof. Background technique [0002] At present, most electric vehicles use larger-capacity power batteries to increase the cruising range of vehicles. Large-capacity power batteries can not only use the electric energy stored in the power batteries for motor driving, but also make it possible for electric vehicles to discharge externally. [0003] Patent Document 1 (CN103187769B) discloses a discharge device for an electric vehicle, which enables the electric vehicle to charge a dead electric vehicle, so as to solve the problem that the electric vehicle cannot travel halfway because the battery power is exhausted. Patent document 2 (CN103187768B) discloses a discharge device for an electric vehicle, which enables the electric vehicle to store electric energy during low peak power consumption, and release the...
