Problems solved by technology

[0004]However, there are still some problems in the existing charging pile charging scheme with multiple charging guns: in the existing charging pile charging scheme with multiple charging guns, Multiple charging guns on the charging pile are usually isolated by high-voltage relays, so there is a danger that multiple charging guns and the power output unit of the charging pile will be connected together at the same time due to the adhesion of the high-voltage relays, making it difficult to ensure Realization of safe charging operation

Embodiment 1

[0051] Such as figure 1 As shown, this embodiment provides a power output control system of a charging pile. Specifically, the power output control system includes:

[0052] A power controller 1, the power controller 1 is used to communicate with the charging controller of the charging pile;

[0053] A plurality of switch controllers 2, and each switch controller 2 is connected to the power controller 1 in communication; for example, in this embodiment, each switch controller 2 is connected to the power controller 1 through a CAN bus;

[0054] A plurality of switch groups 3, each switch group 3 has a plurality of switches 31 that can be closed and turned on or opened to disconnect the electrical connection state of the charging gun 5; the switches 31 in each switch group 3 are connected to the same switch controller Electrical connection; among them, the switch controllers electrically connected to the switches in different switch groups are different; that is to say, once a...

Embodiment 2

[0083] see Figure 4 As shown, this embodiment provides a charging control system having the power output control system described in Embodiment 1. Specifically, the charging control system includes a human-computer interaction unit 6 and at least one charging controller 7 capable of communicating with the vehicle 8 to be charged. The human-computer interaction unit 6 communicates with each charging controller 7, and is characterized in that Each charging controller 7 is communicatively connected to the power controller 1 . Wherein, the human-computer interaction unit 6 in this embodiment is connected to the charging controller 7 through a CAN bus, and each charging controller 7 is connected to the power controller 1 through a CAN bus. The operator can output corresponding instructions to the corresponding charging controller through the operation of the human-computer interaction unit 6, and then the charging controller can adjust and control the work of the corresponding po...

Abstract

The invention relates to a power output control system, charging control system and power output control method for a charging pile. Switch controllers and a plurality of switch sets are additionallyarranged between a power controller and a charging gun, thus all switches in each switch set are electrically connected with the same switch controller, a plurality of power output units are in communication connection with the power controller, and each power output unit is electrically connected with all the switches in the same switch set. According to states sent by all the switches and corresponding switch states fed back by the switch controllers, the power controller judges that the switches are abnormal switch channels when it is judged that two pieces of information for the same switch state are inconsistent, and the power controller shields the abnormal switch channels and the power output units connected with the abnormal switch channels correspondingly; and by additionally arranging the switch controllers and the switches between the power output units and the charting gun, the power output units and the charting gun can be physically isolated, and charging safety is improved.

Description

technical field [0001] The invention relates to the field of charging piles, in particular to a power output control system of a charging pile, a charging control system and a power output control method. Background technique [0002] With the continuous development of the electric vehicle industry, there are more and more charging pile products that meet the charging needs of electric vehicles. By correctly connecting the charging gun of the charging pile to the electric vehicle that needs to be charged (also called "vehicle to be charged"), the power output unit of the charging pile provides electric energy to the charging gun, and then the charging gun realizes the charging. The charging process of an electric car. [0003] Since the charging voltages required by different electric vehicles are often different, most of the existing charging piles will be equipped with multiple charging guns, and each charging gun has a different output voltage, so as to meet the requirem...
