Abstract
The invention relates to a charging station for electric vehicles, with a matrix output. The charging station comprises: at least two power blocks, each having at least two power modules; at least two charging points compliant with the corresponding outputs of the charging station provided with respective charging connectors; a switch matrix with a specific number of inputs and a number of outputs; a control unit and additional units. The invention also relates to a method for controlling the charging station.
Claims15
A charging station for electric vehicles, having a switch matrix with interfaces for connection and communication with a power grid and with at least one charged vehicle, the charging station comprising:
- at least two power blocks, each having at least two power modules, wherein the number of power modules in each of the power blocks is the same;
- at least two charging points compliant with the corresponding outputs of the charging station, provided with respective charging connectors;
- additional units;
- a switch matrix with a specific number of inputs and a specific number of outputs, enabling parallel connection of outputs of the power blocks and their connections to selected charging points and consequently to the outputs of the charging station;
- a control unit that manages, via a bus, the configuration of the charging station and is responsible for controlling and communicating with:
- each of the power blocks and their power modules, the switch matrix and the charging points;
- wherein the control unit, depending on at least:
- assignment of power blocks to charging points, number of charged vehicles and charging parameters reported by them:
- a) defines control strategies for the charging station:
- sharing power blocks according to dynamic assigning them to specific charging points;
- sharing power blocks in accordance with their static assignment to specific charging points;
- b) sets a charging station control regime which depends on the selected control strategy, the type of station and the prioritization of individual outputs at the charging points;
- c) configures the switch matrix, using a controller of the switch matrix, by setting individual switches in a number of sets of switches of the switch matrix, providing a parallel connection of the outputs of selected power blocks and their connections to specific charging points and consequently to the outputs of the charging station;
- d) determines which of the power blocks should be used in the next charging cycle and in what order, taking into account the number of charging cycles and/or the degree of utilization of the rated power of the power block;
- e) determines the operating parameters, i.e. charging current and voltage, for the power modules within each power block, taking into account at least one of the operating parameters of the power module:
- the power at which the module reached maximum efficiency, the number of charging cycles and the degree of utilization of the rated power of the particular power module.
