Based on the above embodiment, please refer to fig. 5 when the charging electrode is disposed in the charging gun, and fig. 5 is a schematic structural diagram of a charging terminal in a charging system provided by an embodiment of the present invention. The charging terminal may include: a first charging circuit 11, a second charging circuit 12, a terminal controller 13, and a communication circuit 14;
the input end of the first charging circuit 11 and the first end of the second charging circuit 12 are both connected with the electric energy output end of the charger; the output end of the first charging circuit 11 is connected with the input end of the charging gun 15, and is used for transmitting the electric energy output by the electric energy output end of the charger to the charging gun 15 and charging the vehicle through the charging gun 15; the second end of the second charging circuit 12 is connected to the energy storage pack, and is configured to transmit the electric energy output by the electric energy output end of the charger to the energy storage pack, or transmit the electric energy output by the energy storage pack to the input end of the first charging circuit 11.
It can be understood that, in this embodiment, two ends of the second charging circuit 12 may be respectively connected to the electric energy output end of the charger and the energy storage pack, and are configured to receive the electric energy output by the electric energy output end of the charger to charge the energy storage pack, or output the electric energy output by the energy storage pack to the first charging circuit 11 together with the electric energy output by the charger to charge the vehicle connected to the charging gun 15.

The charging terminal can also charge the vehicle and the energy storage pack at the same time, for example, the terminal controller 13 can charge the vehicle and the energy storage pack at the same time by using the electric energy output by the charger when the charging gun 15 is connected with the vehicle and the electricity price is low at night.

Specifically, in order to reduce the modification of the charging terminal, in this embodiment, the DC-DC converter is disposed in the energy storage PACK, as shown in fig. 5, the energy storage PACK may include a Battery PACK (Battery PACK) and a DC-DC converter (DC-DC Module), so that electric energy output by the Battery PACK is converted into a target voltage by the DC-DC converter and then output to the second charging circuit of the charging terminal; the battery pack can be connected with a second charging circuit of the charging terminal through the DC-DC converter; the control assembly of the DC-DC converter is connected with the communication circuit of the charging terminal and used for converting the electric energy output by the battery pack into a target voltage according to a communication signal of the communication circuit and outputting the target voltage to the second charging circuit; for example, a controller (e.g., PDU or central control unit CCU) in the charger or a terminal controller in the charging terminal may send a communication signal to the control component of the DC-DC converter through the communication circuit, so as to control the DC-DC converter to convert the voltage of the electric energy output by the battery pack into a voltage equal to the voltage output by the charger.
It can be understood that, in the embodiment, the energy storage pack may charge the battery pack in the energy storage pack by using the electric energy output by the second charging circuit in the charging terminal, and may also output the electric energy of the battery pack to the second charging circuit to charge the vehicle connected to the charging electrode in the charging terminal. For the specific structure type of the DC-DC converter in the energy storage pack, the specific structure type may be set by a designer according to a practical scenario and a user requirement, for example, in order to further reduce the cost of the energy storage pack, since the electric energy output to the energy storage pack by the second charging circuit of the charging terminal when the energy storage pack is charged is the direct current output by the charger, the DC-DC converter in the energy storage pack in this embodiment may specifically be a unidirectional DC-DC converter, which is used to convert the electric energy output by the battery pack into a target voltage and output the target voltage to the second charging circuit; correspondingly, the energy storage pack can further comprise a charging circuit, and the charging circuit is used for transmitting the electric energy output by the second charging circuit to the battery pack, namely the anode and the cathode of the battery pack are connected with the second charging circuit of the charging terminal through the charging circuit; that is to say, when the energy storage pack is discharged, the electric energy of the battery pack can be converted into a target voltage through the DC-DC converter and then output to the second charging circuit of the charging terminal to charge the vehicle connected with the charging electrode; when the energy storage pack is charged, the electric energy output by the second charging circuit of the charging terminal can be output to the battery pack through the charging circuit of the energy storage pack to charge the battery pack of the energy storage pack. In this embodiment, the DC-DC converter in the energy storage pack may also be a bidirectional DC-DC converter, that is, both the charging and the discharging of the energy storage pack may complete the transfer of electric energy through the bidirectional DC-DC converter, which is not limited in this embodiment.
It should be noted that, when the DC-DC converter is specifically a unidirectional DC-DC converter, the specific settings of the DC-DC converter and the charging circuit in the energy storage pack may be set by a designer according to a practical scene and a user requirement, for example, the positive output end of the DC-DC converter may be connected to the second charging circuit of the charging terminal through a diode, that is, the anode of the diode is connected to the positive output end of the DC-DC converter, and the cathode of the diode is connected to the second charging circuit; the negative output terminal of the DC-DC converter may be connected to the second charging circuit of the charging terminal; the charging circuit of the energy storage pack may include a first controllable switch and a second controllable switch, that is, the positive electrode of the battery pack is connected to the second charging circuit of the charging terminal through the first controllable switch, and the negative electrode of the battery pack is connected to the second charging circuit of the charging terminal through the second controllable switch. As shown in fig. 6, the energy storage pack may further include a third controllable switch (S3) and a fourth controllable switch (S4), i.e., the positive output terminal of the DC-DC converter may be connected to the second charging circuit of the charging terminal through a diode (D1) and the third controllable switch (S3) connected in series, the negative output terminal of the DC-DC converter may be connected to the second charging circuit of the charging terminal through the fourth controllable switch (S4), the positive electrode of the battery pack is connected to the second charging circuit of the charging terminal through the first controllable switch (S1), and the negative electrode of the battery pack is connected to the second charging circuit of the charging terminal through the second controllable switch (S2). Correspondingly, the control ends of the first controllable switch to the fourth controllable switch can be connected with a corresponding controller (such as a charging controller) in the energy storage pack, so that the third controllable switch and the fourth controllable switch are switched on and the first controllable switch and the second controllable switch are switched off when the energy storage pack is discharged, the third controllable switch and the fourth controllable switch are switched off and the first controllable switch and the second controllable switch are switched on when the energy storage pack is charged, electric energy cannot pass through the DC-DC converter when the energy storage pack is charged, and electric energy cannot pass through the charging circuit when the energy storage pack is discharged. As long as the energy storage pack is ensured to be charged, the electric energy output by the second charging circuit can be transmitted to the battery pack through the charging circuit of the energy storage pack and cannot flow into the DC-DC converter; when the energy storage pack is discharged, the electric energy output by the battery pack is transmitted to the second charging circuit through the DC-DC converter, and is not transmitted to the second charging circuit through the charging circuit.
It can be understood that, in this embodiment, the energy storage pack may further include a charging controller, which is configured to be connected to a terminal controller of the charging terminal and send charging information (i.e., a charging requirement) to the terminal controller.
