The technical scheme of the application will be described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a rectifying unit according to an embodiment of the application. As shown in fig. 1, the rectifying unit 13 is applied to the vehicle-mounted charging system 10, the vehicle-mounted charging system 10 comprises a wired charging unit 11, a wireless charging unit 12 and the rectifying unit 13, the rectifying unit 13 comprises a first rectifying sub-unit 131, a second rectifying sub-unit 132 and a third rectifying sub-unit 133, the first rectifying sub-unit 131 is connected with the second rectifying sub-unit 132, the second rectifying sub-unit 132 is connected with the third rectifying sub-unit 133, the wired charging unit 11 is connected with the first rectifying sub-unit 131 and the second rectifying sub-unit 132 respectively, the wireless charging unit 12 is connected with the first rectifying sub-unit 131 and the third rectifying sub-unit 133 respectively, and the rectifying unit 13 is used for rectifying current from the wired charging unit 11 or from the wireless charging unit 12.
The wired charging unit may include a wired charger, and the wireless charging unit may include a wireless charger. The wired charging unit and the wireless charging unit can be integrated together to share one rectifying unit, so that charging currents acquired by the wired charging unit or the wireless charging unit are rectified through the same rectifying unit. In a specific implementation, a rectifying unit includes a plurality of rectifying sub-units, and each rectifying sub-unit can be used for rectifying the current acquired by the rectifying unit. In the application, the charging current obtained by the wired charging unit is rectified through the first rectifying subunit and the second rectifying subunit, and the current obtained by the wireless charging unit is rectified through the first rectifying subunit and the third rectifying subunit. That is to say that the wired charging unit and the wireless charging unit share the same rectifying sub-unit. The first rectifying sub-unit, the second rectifying sub-unit, and the third rectifying sub-unit are the same rectifying sub-unit, and thus the wired charging unit and the wireless charging unit may be a common second rectifying sub-unit or third rectifying sub-unit.
Therefore, in the embodiment, the wired charging unit and the wireless charging unit share one rectifying subunit in the rectifying unit to rectify, so that the vehicle can realize wired charging and wireless charging switching, and the cost waste of vehicle components caused when the wired charging unit and the wireless charging unit respectively use one independent rectifying unit can be reduced.
In one possible example, each of the first rectifying sub-unit, the second rectifying sub-unit and the third rectifying sub-unit includes at least one rectifying module, and the at least one rectifying module is used for rectifying the current acquired by the rectifying unit.
Since the first rectifying sub-unit, the second rectifying sub-unit and the third rectifying sub-unit are the same rectifying sub-unit, taking any one rectifying sub-unit as an example, please refer to fig. 2, fig. 2 is a schematic structural diagram of a rectifying sub-unit according to an embodiment of the present application. As shown in fig. 2, at least one rectifying module 201 is included in one rectifying subunit 20, where the rectifying module in the dashed box represents that the rectifying module may or may not be present, i.e. the rectifying module in the rectifying subunit may include one or more rectifying modules. When a plurality of rectifying modules are included in the rectifying sub-unit, the plurality of rectifying modules may be connected in sequence. Each rectifier module may be used to rectify the current flowing into the rectifier sub-unit.
It can be seen that in this example, the rectifying subunit includes at least one rectifying module for rectifying, so that the rectifying effect and the rectifying efficiency on the current flowing into the rectifying unit can be ensured.
In a possible example, referring to fig. 3a and 3b, the rectifying unit 33 further includes a first switch subunit 334 and a second switch subunit 335, wherein a first end of the first switch subunit 334 is connected to the wired charging unit 31, a second end of the first switch subunit 334 is connected to the first rectifying subunit 331 or the second rectifying subunit 332, for controlling the connection relationship between the wired charging unit 31 and the rectifying unit 33 according to a current charging mode, the charging mode includes a wired charging mode or a wireless charging mode, a first end of the second switch subunit 335 is connected to the wireless charging unit 32, and a second end of the second switch subunit 335 is connected to the first rectifying subunit 331 or the third rectifying subunit 333, for controlling the connection relationship between the wireless charging unit 32 and the rectifying unit 33 according to the current charging mode.
The first switch subunit shown in fig. 3a is respectively connected with the wired charging unit and the first rectifying subunit, and the second switch subunit is respectively connected with the wireless charging unit and the first rectifying subunit. In a specific implementation, the first switch subunit is connected with the wired charging unit and the first rectifying subunit respectively, and the second switch subunit is connected with the wireless charging unit and the third rectifying subunit respectively. Or the first switch subunit is connected with the wired charging unit and the second rectifying subunit respectively as shown in fig. 3b, and the second switch subunit is connected with the wireless charging unit and the third rectifying subunit respectively. Or the first switch subunit is respectively connected with the wired charging unit and the second rectifying subunit, and the second switch subunit is respectively connected with the wireless charging unit and the first rectifying subunit. When the charging mode is a wireless charging mode, namely, charging current is acquired through the wireless charging unit, the wired charging unit and the rectifying unit are disconnected through the first switch subunit, and the wireless charging unit and the rectifying unit are connected through the second switch subunit, so that the rectifying unit rectifies the charging current acquired by the wireless charging unit. When the charging mode is a wired charging mode, that is, the charging current is obtained through the wired charging unit, the first switch subunit and the second switch subunit function similarly.
In this example, the connection relationship between the wired charging unit, the wireless charging unit and the rectifying unit is controlled by the first switch subunit and the second switch subunit, so that the vehicle can realize switching between the wired charging mode and the wireless charging mode.
In one possible example, the first switch subunit and the second switch subunit control connection relations between the wired charging unit and the wireless charging unit and the first rectifying subunit respectively according to a current charging mode, wherein the connection relations comprise that a current available charging mode is obtained, and in the case that the current available charging mode comprises a wireless charging mode, the first switch subunit is controlled to be opened and the second switch subunit is controlled to be closed.
The current available charging modes comprise a wired charging mode or a wireless charging mode, if the current available charging mode is the wireless charging mode, the switch state of the first switch subunit is controlled to be opened, and the switch state of the second switch subunit is controlled to be closed, so that the wired charging unit is disconnected from the rectifying unit, and the wireless charging unit is connected with the rectifying unit. The vehicle can acquire charging current through the wireless charging unit, and the rectifying unit rectifies the current acquired by the wireless charging unit. Similarly, if the currently available charging mode is a wireless charging mode, the switch state of the first switch subunit is controlled to be closed, and the switch state of the second switch subunit is controlled to be opened.
It can be seen that in this example, the charging mode can be switched only by changing the switching states of the first switch subunit and the second switch subunit, so that the charging mode can be switched quickly and simply.
In one possible example, the first switch subunit includes a first relay switch and the second switch subunit includes a second relay switch.
The first switching subunit and the second switching subunit can be not only relay switches, but also semiconductor switches for evolution substitution.
Therefore, in this example, by controlling the relay switch, the connection relationship between the wired charging unit and the wireless charging unit and the rectifying unit can be controlled conveniently and rapidly, so as to improve the switching rate of the charging mode.
In a possible example, referring to fig. 4, the rectifying module 40 includes a diode sub-module 41 and a transistor sub-module 42, the diode sub-module 41 is connected in parallel with the transistor sub-module 42, the transistor sub-module 42 is used for rectifying the current obtained by the rectifying unit, and the diode sub-module 41 is used for protecting the circuit of the transistor sub-module 42.
The diode sub-module is connected with the transistor sub-module in parallel, so that when overvoltage occurs, devices in the diode sub-module are broken down reversely, and high current is directly connected to the ground, and the devices in the transistor sub-module are prevented from being burnt out. In a specific implementation, one rectifying subunit comprises two rectifying modules, and the two rectifying modules are connected in series. When rectifying the current acquired by the wired charging unit, the two rectifying modules included in the first rectifying sub-unit and the two rectifying modules included in the second rectifying sub-unit may be regarded together as one rectifying bridge. When the current obtained by the wireless charging unit is rectified in the same way, the two rectifying modules included in the first rectifying subunit and the two rectifying modules included in the third rectifying subunit can be regarded as a rectifying bridge together.
In this example, the rectifying module includes a diode sub-module and a transistor sub-module, which can not only improve the rectifying efficiency, but also ensure the safety of the circuit.
In one possible example, the diode sub-module comprises a diode and the transistor sub-module comprises a field effect transistor.
Wherein the field effect transistor comprises a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET).
