Abstract

Hybrid conversion equipment (1) comprising a hybrid converter (3) formed by a branch (31) of primary semiconductors, a branch (32) of secondary semiconductors, a branch (33) of tertiary semiconductors, and a branch (34) of neutral semiconductors, where: the primary (31), secondary (32), tertiary (33), and neutral (34) branches constitute a dc/ac converter; and the primary (31) and secondary (32) branches constitute a dc/dc converter to provide the dc output (4); where a set (6) of contactors allows to select between the dc output (4) or the ac three-phase output (5), and that also comprises two capacitors (7) connected respectively between the positive and negative pole of the converter input (3) and the neutral (n) to allow regulation of the neutral current of the equipment (1).

formed by three capacitors connected respectively between each phase of the alternating current and the neutral current.

Another preferred embodiment of the invention is directed to a hybrid charging station that

It comprises equipment of the type described above, so that: a) the continuous output allows to obtain a vehicle recharge connection

DC electric type CHAdeMO;

b) the alternating three-phase output allows to obtain a vehicle recharge connection

electrical in three-phase alternating current type IEC 62196-2, and / or in single-phase current

alternating type J1772, and / or in single phase alternating current type Schuko.

Preferably, the charging station of the invention further comprises a processing means that controls the operation of the semiconductors and contactors of the converter depending on the type of load desired at any given time. In addition, the processing means may be in communication with a communication module of the electric vehicle to know the load profile demanded by said vehicle.

In another preferred embodiment, the station further comprises a user input module in communication with the processing means that acts as an interface between the station and the user.

The station may also comprise a communication module with the processing means to allow communication between the station and an external database. In another preferred embodiment, the station also comprises a local database in communication with the processing medium.

A second aspect of the invention is directed to a method of charging an electric vehicle in a hybrid charging station according to the above description, which comprises the steps of:

a) Wait for the connection of a vehicle. b) Identify an electric vehicle and check if the type of recharge is compatible. c) In case of a positive identification in stage b), pre-accept the service of

load and check user permissions to reload. d) Once the user permits have been checked in step c), enable the type of load required by the vehicle until checking that the output voltage meets

conversion. -Activation of the control algorithm in operation depending on the type of output selected. -Communication through the communications module (22) with the vehicle for

5 know the load profile demanded by said vehicle. Note that the Schuko connector is not connected to the communications module (22) given its characteristics.

-Control of the energy assigned by the station (20) to the vehicle. -Error control during operation through the information obtained from 10 sensors internal to the conversion equipment (1) or the errors notified by the vehicle through the communications module (22).

The processing means (21) is also in communication with various equipment such as a user interface (23) to allow communication between the user and the user.

15 station (20). There are different user interface designs depending on the nature of it. However, the interface includes a data display screen, touch or not, a keypad for entering user identification keys and a card reading interface (user and / or credit).

20 The processing medium (21) is also connected to a communication module (24) that allows communication with external networks to be able to carry out real-time queries such as a query to a database (100) external to the station (20) ) of whatever nature (identification, consultation of privileges, etc.). In the event that the corporate network is out of service, a GPRS system could be used to perform the

25 necessary communications. For example, when dealing with the recharging of vehicles from a service to the public, the station (20) must be able to identify the user and for this a general database (100) may be required to all stations (20) of a network in which they can make inquiries.

30 The station (20) can also include a small database (25) to store information that is not related to the user but to data from the network itself, such as the nearest station, kWh price among others and then can be synchronized with the network periodically.

35 The station (20) shown in Fig. 2 also has a communication module (22)
