Embodiment Construction
[0034] exist figure 1 A system overview diagram 100 of load management in one embodiment of the method according to the invention is shown schematically in FIG. In a charging parking lot, this load management involves a charging management server 10 , at least one power electronics module 20 and a charging control device 30 for controlling the charging levels. In this case, the charging management server 10 is the function master and controls by means of a predefined distribution algorithm based on the power characteristic value of the grid power determined at start-up, the transformer power and minus the power requirements of optional peripheral components Or the corresponding charging power to be provided or provided at the corresponding charging point is adjusted. When determining the encoding parameter CaP_LoadManagement_Type 16 , which determines the type of charge allocation, a distinction is made between static allocation types 12 and dynamic or intelligent allocation ...

The invention relates to a load management method of a charging parking lot. At least two charging positions of the charging parking lot are provided with respective charging control devices, power electronic modules assigned to the charging positions, a charging management server and a transformer which is connected with a power supply network and provides transformer power. The load management implemented by the charging management server controls the distribution of transformer power; a charging control device connected with the load management device controls the charging process of the electric vehicle at the charging position; and the power electronic module provides charging power controlled by the load management, wherein the load management has a dynamic implementation mode for distributing transformer power to the charging positions according to at least one preset distribution algorithm and a static implementation mode for uniformly distributing the transformer power to each charging position; the load management is dynamically implemented in a system state in which the charging parking lot is fault-free; and the load management is statically carried out in a system state in which the charging parking lot is faulty. The invention further relates to the charging parking lot operated by the method.
Description
technical field [0001] The invention relates to a method for switching between dynamic load management and static load management of a charging parking lot in the event of a fault. Furthermore, a charging car park operated in this way is claimed. Background technique [0002] Charging parks provide electrical power for charging traction batteries of electric vehicles at a plurality of charging bays. For this purpose, the transformers of the charging car parks are in most cases directly connected to the medium-voltage grid of the local power supply. Therefore, depending on the installation location or installation configuration, the available grid power and / or transformer power of the charging car park is variable or even limited. In this case, the load distribution takes place locally among the power electronics connected to the transformer. The power modules of the power electronics are then switched on for the individual charging points, which serve as a collection of i...
