[0002] With the continuous development of new energy vehicles, electric vehicles have gradually gained the favor of more and more consumers, thus promoting the rapid development of electric vehicle technology.

These terms are only used to distinguish the same type of information from each other.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0054] First, the terms involved in one or more embodiments of this specification are explained.

[0055] Battery Management Unit (BMU): It is the core part of the battery management system and is mainly responsible for real-time monitoring of the battery, including the collection and processing of key parameters such as voltage, current, and temperature. In addition, it also performs functions such as battery status diagnosis, fault warning, and communication with other vehicle subsystems.

[0056] DC-to-DC converter: Also known as a DC / DC converter, it is a circuit or electromechanical device for converting electrical energy. It can convert a direct current (DC) power supply into a DC (or near-DC) power supply of a different voltage.

[0057] In this specification, a charging processing method is provided. This specification also relates to a charging processing device, a computing device, a computer-readable storage medium, and a computer program, which are described in detail one by one in the following embodiments.

[0058] Figure 1 A flowchart of a charging processing method provided according to an embodiment of the present specification is shown. The charging processing method is applied to a charging device, and the charging device includes: a battery pack, a DC / DC converter, a battery management unit and a charging interface, and specifically includes the following steps.

[0059] Step 102: In response to a charging instruction sent by the power supply device through the charging interface, wake up the DC / DC converter and obtain a first required voltage of the battery pack collected by the battery management unit.

[0060] The charging processing method provided in the embodiments of this specification is applied to a charging device, which is configured with a battery pack, a battery management unit, a DC / DC converter and a charging interface, wherein the charging interface is connected to the battery management unit and the DC / DC converter, the battery pack is also connected to the battery management unit and the DC / DC converter, and the charging interface can be a DC charging interface.

[0061] Specifically, the power supply device can be a charging pile, and the charging pile is equipped with a charging gun; the charging device is equipped with a charging interface. When the charging device needs to be charged through the charging pile, the charging gun configured by the charging pile can be inserted into the charging interface of the charging device, thereby realizing information exchange between the charging device and the charging pile.

[0062] In addition, the battery management unit is BMU. BMU can be used to collect and process key parameters such as battery voltage, current, and temperature.

[0063] Based on this, when the charging device needs to be charged through the charging pile and the charging gun configured by the charging pile is inserted into the charging interface of the charging device, the charging pile can send a charging instruction to the charging device through the charging gun, and the charging device receives the charging instruction through the charging interface and responds to the charging instruction to wake up the DC / DC converter. In addition, the charging requirement voltage (first requirement voltage) of the battery pack collected by the BMU can also be obtained for subsequent power supply voltage conversion.

[0064] Furthermore, the charging device also includes a DC / DC enabling interface. The schematic diagram of the DC / DC enabling interface provided in the embodiment of this specification is as follows: Figure 2a The DC / DC enable interface includes at least three pins, and the three pins in the figure are used for fault uploading, grounding, and waking up the DC / DC converter.

[0065] The schematic diagram of the charging interface provided in the embodiment of this specification is as follows Figure 2b As shown. The charging interface contains at least 10 pins. Figure 2b In the figure, A+ and A- of pins 1 and 6 are power lines, which are used to transmit the power delivered by the charging pile through the charging gun. The power can be used to wake up the DC / DC converter of the charging device; pins 2 and 3 are communication lines, which are used for the charging device to communicate with the charging pile; pins 4, 5 and 7 are used for the positive and negative poles of the temperature sensor; PE of pin 9 is used for grounding; CC2 of pin 8 is used by the charging device to confirm whether it is successfully connected to the charging gun; CC1 of pin 10 is used by the charging pile to confirm whether the charging gun and the charging interface are successfully connected.

[0066] The schematic diagram of the battery management unit provided in the embodiment of this specification is as follows Figure 2c As shown. The battery management unit contains at least 14 pins. Figure 2c In the figure, pin 29 is used for fault uploading; pin 30 is used to wake up the battery management unit; pin 13 is a switch for controlling the connection or disconnection of the line; A+ of pin 3 is used to transmit power; pins 10 and 11 are communication lines for communicating with the charging interface; pins 8 and 9 are communication lines for communicating with the quick-change connector interface; 24V+ and 24V- of pins 2 and 28 are power lines for transmitting power; pins 12, 15 and 20 are respectively connected to pins 4, 5 and 7 of the charging interface to transmit relevant information; PE of pin 9 is used for grounding; CC2 of pin 16 is used to connect to pin 8 of the charging interface to transmit relevant information.

[0067] The schematic diagram of some connections inside the charging device provided in the embodiments of this specification is as follows Figure 3 As shown. Among them, the A+ signal is the confirmation signal for inserting the charging gun, that is, after the charging gun is successfully connected to the charging interface, the charging pile sends the A+ signal to the charging interface through the charging gun; after the charging interface receives the A+ signal, it can output it to pin 1 of the DCDC enable interface, thereby waking up the DC / DC converter.

[0068] In practical applications, the A+ signal can be used as a charging instruction, and the charging interface can be a DC charging socket. The charging device receives the A+ signal from the charging gun through the DC charging socket, which is equivalent to receiving a charging instruction. The A+ signal can be transmitted to pin 1 of the DC / DC enable interface, thereby waking up the DC / DC converter to work.

[0069] In an optional implementation, the charging device may first detect the connection relationship between the power device and the charging device before receiving the charging instruction;

[0070] When it is determined that the charging device is disconnected from the power device, step 102 is executed.

[0071] Specifically, the charging device is usually connected to the power device through a quick-change connector to supply power to the power device.

[0072] like Figure 3 As shown, the charging device includes a quick-change connector interface. By inserting the quick-change connector of the power device into the quick-change connector interface, the power device and the charging device can be connected.

[0073] Based on this, whether the power device and the charging device are completely separated can be determined by detecting the connection relationship between the quick-change connector and the quick-change connector interface; when it is determined that the charging device and the power device are disconnected, that is, the charging device and the power device are completely separated, execute step 102 to realize direct charging of the charging device through the charging gun without the need to use the charging interface configured by the power device to charge the charging device.

[0074] In practical applications, the charging device may be an onboard power supply of an electric device such as an electric vehicle.

[0075] Step 104: converting the DC power supply of the power supply device according to the first required voltage by the DC / DC converter to obtain a converted first DC power supply.

[0076] Specifically, a DC / DC converter can convert a DC power source into a DC (or approximately DC) power source of a different voltage.

[0077] like Figure 3 As shown, the charging device includes a DC / DC converter. The embodiment of this specification converts the voltage of the DC power output by the power supply device through the buck-boost circuit of the DC / DC converter, and converts it into a DC power supply (first DC power supply) that is compatible with the charging requirement voltage of the charging device.

[0078] Step 106: Deliver the first DC power supply to the battery management unit, and charge the battery pack through the first DC power supply, wherein the charging device is used to supply power to the power device.

[0079] Specifically, after the voltage of the DC power supply of the power supply device is converted according to the charging requirement voltage of the battery pack, the battery pack of the charging device can be charged by the converted power supply.

[0080] In actual applications, the BMU is responsible for monitoring the charging and discharging process of the battery pack to ensure that it operates within a safe range. It monitors key parameters of the battery pack, such as voltage, current, and temperature, and transmits these data to the system regulator to adjust the charging state; during the charging process, the BMU will adjust the charging rate according to the battery status to prevent overcharging and overheating, ensuring a safe and reliable charging process; in addition, the BMU will communicate with the charging pile and adjust the charging state based on the transmitted data to ensure a smooth charging process.

[0081] Based on this, after the DC / DC converter converts the DC power of the power supply device into DC according to the charging requirement voltage of the charging device, the converted DC power can be transmitted to the battery management unit, so that the charging process of the battery pack is controlled by the battery management unit to realize charging of the battery pack.

[0082] The charging device described in the embodiments of this specification can be used for charging vehicles or other electric devices that support battery replacement.

[0083] In an optional embodiment, the charging device further includes a cooling unit;

[0084] Accordingly, the method further includes:

[0085] Determining a second required voltage corresponding to the cooling unit;

[0086] Converting the DC power supply of the power supply device according to the second required voltage by the DC / DC converter to obtain a converted second DC power supply;

[0087] The second DC power supply is transmitted to the cooling unit to supply power to the cooling unit.

[0088] Specifically, during the charging process of the battery pack, in order to prevent local overheating of the charging device and ensure a safe and reliable charging process, the embodiment of this specification provides a cooling unit inside the charging device, and supplies power to the cooling unit so that the cooling unit can work normally to achieve cooling of the inside of the charging device.

[0089] Based on this, when powering the cooling unit, the input voltage (second required voltage) of the cooling unit can also be determined first, and then the DC power supply of the power supply device can be converted according to the input voltage through a DC / DC converter, and the converted second DC power supply can be transmitted to the cooling unit to power it.

[0090] In practical applications, the required charging voltage of the battery pack and the input voltage of the cooling unit can both be 24V. In this case, the DC / DC converter only needs to perform a voltage conversion on the DC power supply of the power supply equipment, and then transmit the converted DC power supply to the BMU and the cooling unit.

[0091] like Figure 3 As shown, the A+ signal of the charging port is transmitted to pin 3 of the BMU, and the BMU is awakened. At the same time, the DC / DC converter outputs a stable 24V voltage and transmits it to the BMU and the cooling unit at the same time. In this case, the cooling unit can continue to work normally and the battery pack can also be charged normally. In addition, Figure 3 Diode 1 in FIG. 1 can be used to prevent voltage from being injected into pin 30 of the BMU.

[0092] In an optional implementation, when it is determined that the charging device is connected to the power device, the operating state of the power device is detected;

[0093] When it is determined according to the operating state that the power device is running, the third DC power source output by the quick-change connector interface is transmitted to the battery management unit, and the battery management unit is awakened;

[0094] The third direct current power source is delivered to the DC / DC enabling interface through the battery management unit, and the DC / DC converter is awakened through the DC / DC enabling interface.

[0095] Furthermore, the charging device also includes a cooling unit;

[0096] Accordingly, the method further includes:

[0097] Determining a second required voltage corresponding to the cooling unit;

[0098] Converting the third DC power source according to the second required voltage by the DC / DC converter to obtain a converted fourth DC power source;

[0099] The fourth DC power supply is transmitted to the cooling unit to supply power to the cooling unit.

[0100] The schematic diagram of the quick-change connector interface provided in the embodiment of this specification is as follows Figure 2d As shown. The quick-change connector interface contains at least 6 pins. Figure 2d In the figure, pins 1 and 2 are used to transmit power; pin 3 is a switch used to control the connection or disconnection of the line; pins 4 and 5 are communication lines used to communicate with the battery management unit; and pin 7's A+ is used to transmit power.

[0101] Specifically, as mentioned above, in the embodiment of the present specification, a cooling unit is provided inside the charging device, and the cooling unit is powered so that the cooling unit can operate normally to achieve cooling of the inside of the charging device. In the aforementioned embodiment, when the battery pack in the charging device is charged by the power supply device, the cooling unit can also be powered by the power supply device.

[0102] However, if the charging device and the power device are not separated, that is, the charging device and the power device are in a connected state, and the power device is in an operating state, and the charging device provides power to the power device, the charging device cannot be charged by an external power supply during the operation of the power device, and the cooling unit cannot be powered by an external power supply.

[0103] Therefore, when it is determined that the charging device and the power device are not separated, the operating state of the power device is detected, that is, it is determined whether the power device is running or in a stationary state; when it is determined that the power device is running, the cooling unit is powered by the battery pack of the charging device.

[0104] In this case, the DC power output by the quick-change connector interface can first be transmitted to the battery management unit to power the battery management unit, and pin 3 of the quick-change connector interface can be controlled to close, thereby waking up the battery management unit; then the battery management unit powers pin 1 of the DC / DC enable interface through pin 30, thereby waking up the DC / DC converter to work.

[0105] In practical applications, the DC power output by the quick-change connector interface can come from a battery configured for the power equipment.

[0106] After the DC / DC converter is awakened, the DC / DC converter can convert the DC power of the battery pack according to the input voltage of the cooling unit, and transmit the converted fourth DC power to the cooling unit to power it.

[0107] like Figure 3 As shown, when it is determined that the power equipment is running, pins 1 and 2 of the quick-change connector interface transmit 24V power to the BMU for power supply, and control pin 3 of the quick-change connector interface to close to wake up the BMU. After the BMU is awakened, it supplies power to pin 1 of the DC / DC enable interface through pin 30 to wake up the DC / DC converter to work, so that the DC / DC converter converts the voltage of the high-voltage DC power supply of the battery pack, and provides a stable 24V power supply to the cooling unit through the output end to ensure that the cooling unit can continue to work normally. In addition, Figure 3 The diodes 3 and 4 in the embodiment are used to ensure that the voltage of the BMU pin 30 will not be connected to the pin 3 of the BMU and the pin 7 of the quick-change connector interface.

[0108] In an optional embodiment, when it is determined that the power device is stationary according to the operating state, in response to a charging instruction sent by the power supply device, the DC power of the power supply device is transmitted to the battery management unit through the quick-change connector interface, and the battery management unit is awakened;

[0109] The DC power supply is delivered to the DC / DC enabling interface through the battery management unit, and the DC / DC converter is awakened through the DC / DC enabling interface.

[0110] Alternatively, when it is determined according to the operating state that the power device is stationary, step 102 is executed.

[0111] Specifically, when it is determined that the charging device and the power device are not separated, if it is determined that the power device is in a stationary state, and the power device receives a charging instruction sent by the power supply device, the battery pack of the charging device can also be charged through the power supply device, and the cooling unit of the charging device can also be powered by the power supply device.

[0112] In actual applications, the power equipment is provided with a charging port. When the power supply equipment is a charging pile, if the power equipment needs to be charged through the charging pile, the charging gun of the charging pile can be inserted into the charging port of the power equipment to establish a connection with the power equipment. Then the charging gun of the charging pile transmits DC power to the charging equipment through the quick-change connector interface to charge the battery pack of the charging equipment.

[0113] In this case, the DC power supply of the power supply device output by the quick-change connector interface can be first transmitted to the battery management unit to power the battery management unit, and pin 3 of the quick-change connector interface can be controlled to close, thereby waking up the battery management unit; then the battery management unit powers pin 1 of the DC / DC enable interface through pin 30, thereby waking up the DC / DC converter to work.

[0114] In addition, as mentioned above, the embodiments of the present specification provide a cooling unit inside the charging device, and by supplying power to the cooling unit, the cooling unit can operate normally to achieve cooling of the interior of the charging device, and in the aforementioned embodiments, when the battery pack in the charging device is charged by the power supply device, the cooling unit can also be powered by the power supply device.

[0115] The embodiments of this specification can also power the cooling unit through the power supply equipment. Specifically, after the DC / DC converter is awakened, the high-voltage DC power supply of the power supply equipment can be converted into voltage according to the input voltage of the cooling unit through the DC / DC converter, and the converted voltage can be transmitted to the cooling unit to power it.

[0116] In addition, even when the charging device is not separated from the power device, since the charging device is provided with a charging interface, the charging gun can be directly inserted into the charging interface to charge the battery pack of the charging device.

[0117] like Figure 3 As shown, when the charging device and the power device are not separated, when charging the charging device, the A+ signal of the charging interface is transmitted to pin 3 of the BMU, the BMU is awakened, and the 24V power of pins 1 and 2 of the quick-change connector interface is transmitted to the BMU for power supply. After the BMU is awakened, it supplies power to pin 1 of the DC / DC enable interface through pin 30 to wake up the DC / DC converter to work, so that the DC / DC converter performs voltage conversion on the high-voltage DC power supply of the power supply device, and provides a stable 24V power supply to the cooling unit through the output end to ensure that the cooling unit can continue to work normally. At the same time, the A+ signal of the charging interface can also be directly output to pin 1 of the DC / DC enable interface to wake up the DC / DC converter to work normally. The A+ signal of the charging interface is also output to the quick-change connector interface for use by the power device. After the DC / DC converter is awakened, the 24V power obtained by the DC / DC converter through voltage conversion of the high-voltage DC power supply of the power supply device can also be directly output to the power pin of the BMU for power supply. In addition, Figure 3 The diodes 5 and 2 are used for circuit isolation.

[0118] besides, Figure 3 The charging device shown also includes a high-voltage control unit, which includes at least two relays for controlling the connection and disconnection between the battery pack and the DC / DC converter or other units or modules.

[0119] An embodiment of the present specification responds to a charging instruction sent by a power supply device through a charging interface, wakes up a DC / DC converter, and obtains a first required voltage of a battery pack collected by a battery management unit; converts the DC power supply of the power supply device according to the first required voltage through a DC / DC converter to obtain a converted first DC power supply; transmits the first DC power supply to the battery management unit, and charges the battery pack through the first DC power supply, wherein the charging device is used to power the power device. The embodiment of the present specification configures a charging interface on the charging device and configures a DC / DC converter inside the charging device, so that the user can directly charge the charging device through the power supply device, thereby improving the convenience of the user charging the power supply of the power device, i.e., the charging device, during the use of the power device, thereby helping to improve the user experience.

[0120] The following combination Figure 4Taking the application of the charging processing method provided in this specification in the charging scenario of a large electric agricultural vehicle as an example, the charging processing method is further described. Figure 4 A processing flow chart of a charging processing method provided in an embodiment of the present specification is shown, which specifically includes the following steps.

[0121] Step 402: Detect the connection relationship between the electric agricultural vehicle and the vehicle battery.

[0122] If it is determined that the onboard battery is disconnected from the electric agricultural vehicle, step 404 is executed; if it is determined that the onboard battery is not disconnected from the electric agricultural vehicle, step 416 is executed.

[0123] Step 404: In response to the charging instruction sent by the charging gun through the charging interface of the vehicle-mounted battery, the DC / DC converter is awakened, and the first required voltage of the battery pack collected by the battery management unit is obtained.
