Problems solved by technology

However, this solution has the problem that the mathematical model is based on historical data and the vehicle does not necessarily respond. The current model generally has a relatively large deviation, and most AC charging does not support real-time adjustment of charging power.

Embodiment 1

[0058] Such as figure 1 As shown, an ordered charging control method in this embodiment is applicable to DC charging piles, and at least includes:

[0059] Step 11: Obtain the real-time load of the transformer in the station area, the real-time charging demand power of the vehicle and the real-time operation status of the charging pile.

[0060] Specifically, before implementing this step, corresponding configurations need to be performed on the side of the transformer device and the side of the sequential charging controller.

[0061] (1) Transformer equipment side

[0062] In order to obtain the current power consumption information of the transformer, it is necessary to install a multifunctional transformer information acquisition device on the low-voltage side of each dedicated line of the transformer (in principle, the current transformer is installed at the main low-voltage incoming line) to collect and upload the power consumption information to Orderly charge control...

Embodiment 2

[0092] The sequential charging control method of this embodiment is applicable to AC charging piles.

[0093] The power of the AC charging pile is essentially controlled by the on-board charger. At present, the maximum output power of the on-board charger can be controlled by the duty cycle of the PWM wave of the AC charging pile. When the output of the PWM wave stops, the vehicle stops charging.

[0094] The ordered charging control method of this embodiment at least includes:

[0095] Step 21: Obtain the real-time load of the transformer in the station area, the real-time charging demand power of the vehicle and the real-time operation status of the charging pile.

[0096] Specifically, before implementing this step, corresponding configurations need to be performed on the side of the transformer device and the side of the sequential charging controller.

[0097] (1) Transformer equipment side

[0098] In order to obtain the current power consumption information of the tra...

Embodiment 3

[0119] The sequential charging controller of this embodiment is configured to implement the sequential charging control method described in the first embodiment.

[0120] The orderly charging controller of this embodiment realizes the orderly charging of the electric vehicle by combining the charging state of the electric vehicle, the user's usage habits, and the load information collection method of the transformer station area.

Abstract

The invention discloses an orderly charging control method, controller and system. The orderly charging control method is suitable for direct-current charging piles and includes: and includes: acquiring real-time load of a station transformer, real-time charging demanded power of vehicles and real-time running condition of the charging piles; on the premise that the load of the station transformerdoes not exceed a limit, formulating an orderly charging strategy, and issuing the same to the charging piles, wherein the orderly charging strategy includes: charging the vehicles according to preset priority and preset output power of the charging piles if total charging demanded power of the vehicles does not exceed current residual power of the station transformer; when the total charging demanded power exceeds the current residual power, the charging piles with higher priority work at full power in a prioritized manner, and the charging piles with lower priority charge through power smooth adjusting. By the method, orderly charging of electromobiles is realized, and matching between charging load of the electromobiles and power supply capacity of a power distribution network is realized through orderly charging control by utilizing the characteristic of energy-type load of the electromobiles, so that power supply of the electromobiles and running safety of the power distributionnetwork are ensured.

Description

technical field [0001] The invention belongs to the field of electric vehicle charging, and in particular relates to an orderly charging control method, controller and system. Background technique [0002] At present, most electric vehicle charging equipment adopts the method of instant charging. The charging pile cannot control the timing and charging power of electric vehicles; The operation of the distribution network does not charge according to the most suitable method and time for the operation of the power grid. With the increase in the number of electric vehicle users, the large-scale and disorderly charging of electric vehicles will further aggravate the uncertainty of the power grid, worsen the operating indicators of the power system, and cause the residents' load to "peak on top of the peak", forcing the power supply equipment to increase and expand. The utilization rate of power supply equipment is reduced, which is not conducive to the stable and economical op...
