Problems solved by technology

[0003] In the above-mentioned method in which the charging of the vehicle fleet is influenced in order to compensate for an overload in the grid, it may arise that the power reduction desired by the grid operator cannot be achieved by interrupting the charging process of the energy storage on the vehicle side. to achieve, because charging can only be interrupted for a small number of vehicles for the purpose of following the departure time

Embodiment Construction

[0026] exist figure 1 The basic architecture for implementing the method according to the invention is shown schematically in FIG. The core component of this infrastructure is the central control unit CO, which is integrated in the server SE and serves to control the charging of a fleet of electrically driven vehicles, ie the drive batteries of these vehicles. Three electric vehicles 1 in the fleet are described by way of example. These vehicles are connected to the control unit CO via a portal PT in terms of communication. The control system CO has access via a suitable control backend (not shown) to said portal PT, which in turn is able to communicate with the respective vehicle 1 eg via SMS. The charging time window can be transmitted from the control system CO to the individual vehicle 1 by means of a communication path via the portal PT, as will be explained below.

[0027] Each individual vehicle 1 user of the fleet has a smartphone 2 , only a single smartphone being ...

Abstract

The invention relates to a method for controlling the electrical charging of a vehicle fleet. A central control system can communicate with the corresponding vehicles of the group and with a server of the grid operator. A charging time window, a departure time and a desired state of charge of the vehicle-side energy store at the departure time are respectively predetermined for one or more specified vehicles of the group. The central control system transmits the modified charging time window to corresponding designated ones of at least some of the designated vehicles, and then follows the modified charging time window according to the modified charging time criteria without changing the departure time and the desired state of charge. A modified charging time window implements the charging process. The modified charging time window includes at least one time period before the start of the unmodified charging time window, the cost value for the modified charging time window according to the cost function is equal to or less than that for the unmodified charging time window The cost value for the charging time window.

Description

technical field [0001] The invention relates to a method for controlling the electrical charging of a vehicle fleet and a corresponding control system. Background technique [0002] It is known from the prior art to control the charging of the energy stores of groups or fleets of electrically drivable vehicles via a control system in such a way that the requirements of the operator of the grid used for charging with regard to power reduction are also taken into account. In other words, the charging of certain vehicles of the fleet can be interrupted or delayed at the corresponding request of the grid operator in order thereby to reduce the power absorption in the grid. In this case, charging is only interrupted for vehicles in which the interruption of the charging process has no effect on the departure time specified by the vehicle user, ie there is always enough time to resume the charging process even at a later time. Fully charge the vehicle or charge it to a predetermi...
