Description

Technical Field

[0001] This disclosure pertains to the field of electric vehicle technology, and particularly relates to a charging control device, a charging pile, a charging method, and a vehicle. Background Technology

[0002] With the development of electric vehicle technology, two main charging methods exist in the charging field: AC charging and DC charging. AC charging involves AC power being delivered to the battery via an on-board charger (OBC) from an AC charging station. DC charging, on the other hand, converts AC power to DC power via a DC charging station before delivering it to the battery. The most significant difference between these two methods is that AC and DC charging stations have different charging interfaces, and the vehicle also has two charging sockets, one for AC and one for DC. This charging method offers a poor user experience; users may have difficulty distinguishing which socket is for AC and which is for DC. Furthermore, from a vehicle design perspective, two charging ports are large and inconvenient for vehicle layout, and require two sets of high-voltage wiring harnesses, increasing costs. Summary of the Invention

[0028] Embodiments of this disclosure are described in detail below, with examples of embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0029] The terms "first" and "second," etc., used in the specification, claims, and drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the present disclosure described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] With the development of electric vehicle technology, two main charging methods exist in the charging field: AC charging and DC charging. AC charging involves AC power being delivered to the battery via an on-board charger (OBC) from an AC charging station. DC charging, on the other hand, converts AC power to DC power via a DC charging station before delivering it to the battery. The most significant difference between these two methods is that AC and DC charging stations have different charging interfaces, and the vehicle also has two charging sockets, one for AC and one for DC. This charging method offers a poor user experience; users may have difficulty distinguishing which socket is for AC and which is for DC. Furthermore, from a vehicle design perspective, two charging ports are large and inconvenient for vehicle layout, and require two sets of high-voltage wiring harnesses, increasing costs.

[0031] The technical solutions of this disclosure and how they solve the aforementioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of a charging control circuit provided for an exemplary embodiment of the present disclosure. The charging control device 10 includes: a first switch module 101, a second switch module 102, and an AC / DC converter 103.

[0033] The first end of the first switch module 101 is connected to the charging pile 20, the second end of the first switch module 101 is connected to the first end of the second switch module 102, the second end of the second switch module 102 is connected to the vehicle battery 30, and the AC / DC conversion device 103 is connected in parallel with the second switch module 102.

[0034] In some embodiments, the AC / DC converter 103 is used to control the switching state of the second switch model 102 based on the charging signal sent by the charging pile 20 after receiving the charging signal, so as to realize the charging pile charging the vehicle battery.

[0035] Specifically, during the actual charging process, the AC / DC converter 103 controls the second switch module 102 to be closed, which enables the charging pile to be directly connected to the vehicle battery. If the second switch module 102 is controlled to be open, the charging pile can be connected to the vehicle battery through the AC / DC converter 103.

[0036] In some embodiments, the charging pile 20 is a DC charging pile or an AC charging pile.

[0037] In some embodiments, the charging signal includes a charging protocol type identifier. This charging protocol type identifier includes both a DC charging protocol identifier and an AC charging protocol identifier.

[0038] In some embodiments, when the AC / DC conversion device 103 detects that the charging protocol type identifier contained in the charging signal is a DC charging protocol identifier, it controls the second switch module 102 to close, so that the charging pile 20 and the vehicle battery 30 are directly connected.

[0039] In some embodiments, when the AC / DC converter 103 detects that the charging protocol type identifier contained in the charging signal is an AC charging protocol identifier, it controls the second switch module 102 to disconnect, so that the charging pile 20 is connected to the vehicle battery 30 through the AC / DC converter 102.

[0040] During actual charging, when the charging gun corresponding to the charging pile 20 is inserted into the car's charging interface, the AC / DC converter 103 receives the charging signal sent by the charging pile 20. The AC / DC converter 103 identifies the charging protocol type identifier contained in the charging signal. If the charging protocol type identifier is a DC charging protocol identifier, the second switch module 102 is controlled to close, so that the charging pile 20 and the vehicle battery 30 are directly connected. If the charging protocol type identifier is an AC charging protocol identifier, the second switch module 102 is controlled to open, so that the charging pile 20 is connected to the vehicle battery 30 through the AC / DC converter 103. The AC / DC converter 103 converts AC power into DC power, thereby powering the vehicle battery.

[0041] In some embodiments, the first end of the first switch module 101 is provided with a DC charging gun interface.

[0042] In some embodiments, such as Figure 2 As shown, the AC / DC conversion device 103 further includes: a detection unit 1031 and a communication unit 1032.

[0043] The detection unit 1031 is used to detect the shutdown signal generated when the vehicle battery 30 is fully charged; the communication unit 1032 is used to send the shutdown signal to the charging pile 20.

[0044] In some embodiments, continue as follows Figure 2 As shown, the AC / DC conversion device 103 also includes a data acquisition unit 1033;

[0045] The acquisition unit 1033 is used to acquire various power data of the vehicle battery 30.

[0046] The communication unit 1032 is also used to send the various power parameters to the charging pile.

[0047] The electrical data mentioned above include at least the following parameters: voltage, current, and temperature.

[0048] Specifically, during the actual charging process, the communication unit 1032 will send BCS, BSM and other messages to the charging pile in real time.

[0049] The BCS message refers to the overall state of battery charging, which includes the remaining battery charge percentage, remaining charging time, and charging voltage requirements.

[0050] The BSM message refers to battery status information, specifically including insulation resistance status, total battery voltage and current, and fault alarm codes (such as overvoltage and overtemperature).

[0051] In some embodiments, continue as follows Figure 2 As shown, the AC / DC conversion device 103 further includes a conversion unit 1034, which is used to convert the AC power delivered by the charging pile 20 into DC power when the charging pile 20 is connected to the vehicle battery 30 through the AC / DC conversion device 102, thereby realizing the power supply to the vehicle battery.

[0052] The technical solution provided in this disclosure includes a first terminal of the first switch module connected to a charging pile, a second terminal of the first switch module connected to the first terminal of the second switch module, and a second terminal of the second switch module connected to the vehicle battery. The AC / DC conversion device is connected in parallel with the second switch module. The AC / DC conversion device, upon receiving a charging signal from the charging pile, controls the switching state of the second switch module based on the charging signal, thereby enabling the charging pile to charge the vehicle battery. This technical solution allows both DC and AC charging piles to charge the vehicle battery through a charging control device, simplifying the number of charging ports, saving costs, and improving charging efficiency.

[0053] Figure 3 This is a schematic diagram of the structure of a charging pile provided for an exemplary embodiment of the present disclosure. The charging pile 20 includes: a processor 201, a power supply module 202, a charging gun 203, and a communication module 204.

[0054] The power supply module 202 is a DC power supply module or an AC power supply module, and the charging gun 203 is a DC charging gun.

[0055] When the DC charging gun is connected to any of the charging control devices described in the above embodiments, the processor 201 is used to control the communication module 204 to send a charging signal carrying a charging protocol type identifier to the charging control device, and to receive a feedback signal returned by the charging control device in response to the charging signal; based on the feedback signal, the processor 201 controls the power supply module 202 to charge the charging control device.

[0056] In some embodiments, when the communication module 204 receives a shutdown signal sent by the charging control device, the processor 201 controls the power supply module 202 to stop operating and controls the first switch module connected to the DC charging gun to disconnect.

[0057] Specifically, in the actual charging process, if the power supply module 202 in the charging pile 20 is a DC power supply module, then the charging pile 20 is a DC charging pile; if the power supply module 202 in the charging pile 20 is an AC power supply module, then the charging pile 20 is an AC charging pile.

[0058] Combination Figure 3 As shown, in the actual charging process, if you want to charge the vehicle battery 20, you need to insert the charging gun 203 into the interface of the electric vehicle. In this disclosure, the charging gun 203 is a DC charging gun. Both DC and AC charging piles are equipped with DC charging guns. This arrangement ensures that the interfaces of electric vehicles using AC or DC charging are consistent, saving costs and improving charging efficiency.

[0060] S301 receives charging signals sent by the charging pile.

[0061] S302, based on the charging signal, when the first switch module is closed, the switching state of the second switch module is controlled to realize the charging pile charging the vehicle battery.

[0063] In some embodiments, for step S301 described above, the charging signal may refer to a CRM message or other types of messages. The specific settings can be adjusted according to the actual situation.

[0064] Specifically, during the actual charging process, after the charging pile is connected to the charging control device, the charging control device receives a charging signal from the charging pile and then adjusts the relevant second switch module according to the charging signal.
