[0068] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0069] Example 1

[0070] Figure 1 A battery box data interaction system of the present embodiment is shown. The battery box data interaction system includes: a vehicle battery replacement control system 11 and a battery box system 12 provided on a vehicle battery box. Among them, the vehicle battery replacement control system 11 is usually managed and owned by a battery replacement station or other professional organization that can replace batteries for vehicles. However, it should be noted that the vehicle battery replacement control system 11 is not limited to working in a battery replacement station or professional organization. The vehicle battery replacement control system 11 can also control the vehicle battery box while the vehicle is driving, and can also provide battery replacement services in any area such as public roads, outdoor places, etc. outside the battery replacement station or professional organization to cope with the situation where the vehicle needs emergency battery replacement.

[0071] The vehicle battery replacement control system 11 can be implemented by, but is not limited to, a backend server, or a control circuit module installed in a battery replacement device for a vehicle. The battery box system 12 can be implemented using a control circuit module of a vehicle battery box.

[0072] The vehicle battery replacement control system 11 includes a battery replacement control module 111 and a first data transmission module 112. The battery box system 12 includes a battery control module 121 and a second data transmission module 122. The battery replacement control module 111 is electrically connected to the first data transmission module 112, and the battery control module 121 is electrically connected to the second data transmission module 122. In order to realize long-distance data transmission and signal interaction between the vehicle battery replacement control system 11 and the battery box system 12, the first data transmission module 112 and the second data transmission module 122 are preferably connected by wireless communication, which can be achieved by but is not limited to wireless communication technologies such as 4G and Bluetooth.

[0073] The battery replacement control module 111 is used to generate control information and transmit the control information to the first data transmission module 112.

[0074] The first data transmission module 112 is configured to send the control information to the second data transmission module 122 .

[0075] The second data transmission module 122 is configured to receive the control information and transmit the control information to the battery control module 121 .

[0076] In this embodiment, the control information can include at least one of a power-off command, a power-on command, a deceleration command, and an acceleration command. The battery control module 121 is further configured to execute the control information.

[0077] The battery control module 121 can generate the control information in response to a manual control command, or generate the control information when a preset condition is met. The preset condition can be self-set, for example, a deceleration command is sent to the battery control module 121 when the vehicle is overspeed, or a power-off command is sent to the battery control module 121 before the vehicle is replaced with a new battery, etc. The second data transmission module 122 can be integrated in the battery control module 121. Alternatively, the second data transmission module 122 can be separately arranged from the battery control module 121. The so-called separate arrangement means that the second data transmission module 122 and the battery control module 121 are implemented by different chips, but the two chips can be arranged on the same circuit board or different circuit boards.

[0078] In actual application, the above signal interaction between the vehicle battery replacement control system 11 and the battery box system 12 can occur before the battery replacement equipment replaces the battery for the vehicle. At this time, the battery box system receiving the control information is the battery box system arranged on the original vehicle battery box of the vehicle, which is hereinafter referred to as the battery box system in power shortage. The vehicle battery replacement control system 11 sends the control information to the battery box system in power shortage. After receiving the control information, the battery box system in power shortage can cooperate with or guide the vehicle battery replacement control system 11 or the battery replacement equipment to further implement the battery replacement operation.

[0079] Embodiment 2

[0080] The embodiment is a further improvement of the embodiment 1. In the battery box data interaction system of the embodiment, in order to cooperate with and guide the vehicle battery replacement control system 11 or the battery replacement equipment to further realize the battery replacement operation, the battery control module 121 can be used to judge whether the vehicle battery box has been disconnected from the electrical connection with the vehicle after receiving the control information, and if not, control the vehicle battery box to be disconnected from the electrical connection with the vehicle. Alternatively, the battery control module 121 can also be used to control the vehicle battery box to be disconnected from the electrical connection with the vehicle directly after receiving the control information without judgment. The electrical connection between the vehicle battery box and the vehicle includes high-voltage and low-voltage connection between the vehicle battery box and the vehicle when the vehicle battery box supplies power to the vehicle, and both high-voltage and low-voltage need to be disconnected when the electrical connection is disconnected. The battery control module 121 can specifically realize the control of the vehicle battery box to be disconnected from the electrical connection with the vehicle by using various technical means, such as controlling switches, relays, and disconnecting the connection circuit between the vehicle battery box and the vehicle, and the embodiment will not be exemplified one by one. The battery control module 121 can also feed back a power-off completion command to the battery replacement control module 111 through the second data transmission module 122 after determining that the vehicle battery box is disconnected from the electrical connection with the vehicle.

[0081] In the embodiment, the battery box system 12 can further collect information of the vehicle battery box and upload the information to the vehicle battery replacement control system 11. The vehicle battery replacement control system 11 can realize real-time detection of the state of the vehicle battery box according to the information, effectively track the battery state, and help to manage the vehicle battery box uniformly.

[0082] Specifically, the battery control module 121 is also used to collect battery information of the vehicle battery box and transmit the battery information to the second data transmission module 122. The second data transmission module 122 is also used to send the battery information to the first data transmission module 112. The first data transmission module 112 is also used to receive the battery information and transmit the battery information to the battery replacement control module 111. The battery information can specifically include battery operation information, and the battery operation information includes at least one of the previous battery replacement station, the previous battery replacement time, and the battery mileage. The battery information can also include battery state information, and the battery state information includes at least one of the battery voltage, the battery current, and the battery temperature.

[0083] In addition, the battery control module 121 can be configured to collect the battery information in real time (regardless of whether the battery box is installed on the vehicle or whether the vehicle is running or entering the battery swap station), or can be configured to collect the battery information in response to an information acquisition request received from the battery swap control module 111.

[0084] Of course, the battery control module 121 can also be configured to collect the battery information of the battery box under certain conditions, such as collecting the battery information of the battery box after the vehicle is parked, or collecting the battery information of the battery box after the battery control module 121 receives the control information, or collecting the battery information of the battery box after the battery control module 121 receives a collection command sent by the battery control module 121 or the vehicle battery swap control system 11 (which can be sent in any case), and so on.

[0085] In order to comprehensively collect various information of the battery box, the battery box system 12 can further include a battery management system 123. The battery management system 123 is used to store the battery information of the battery box. The battery control module 121 can collect the battery information from the battery management system.

[0086] By uploading the battery information of the battery box to the battery box system 12, the vehicle battery swap control system 11 can effectively grasp the battery status, determine whether the battery box is overheated or the power supply is normal, and further determine whether the battery box is intact or damaged. In addition, the vehicle battery swap control system 11 can also upload the battery information of the battery box to a remote data center or a cloud platform for further data processing and analysis by the remote data center or the cloud platform.

[0087] The battery control module 121 can be integrated into the battery management system 123. Alternatively, the battery management system 123 can be separately provided from the battery control module 121. The so-called separate arrangement means that the battery control module 121 and the battery management system 123 are implemented separately using different chips, but the two chips can be arranged on the same circuit board or different circuit boards.

[0088] The second data transmission module 122 can be integrated into the battery management system 123. Alternatively, the second data transmission module 122 can be separately provided from the battery control module 121 and the battery management system 123. The so-called separate arrangement means that the second data transmission module 122 and the battery control module 121 and the battery management system 123 are implemented separately using different chips, but the chips can be arranged on the same circuit board or different circuit boards.

[0089] In practical applications, before the battery replacement equipment replaces the battery for the vehicle, the battery box system needs to ensure that the original vehicle battery box on the vehicle is disconnected from the vehicle, and then upload the battery information of the original vehicle battery box on the vehicle. Only then can the vehicle battery replacement control system 11 further control the battery replacement equipment to perform the battery replacement operation. The specific battery replacement operation usually includes: removing the original vehicle battery box on the vehicle, and installing a new (sufficient power) vehicle battery box to the vehicle.

[0090] Embodiment 3

[0091] This embodiment is a further improvement of embodiment 2. Considering that there are some bad car owners who privately replace the battery or steal the battery of other vehicles, resulting in the loss of high-quality battery boxes in the battery replacement station or the battery replacement place. In order to strengthen the management of the battery box, in the battery box data interaction system of this embodiment, the battery box system 12 also has the function of locking and unlocking the power supply function of the vehicle battery box. When the power supply function of the vehicle battery box is locked, the vehicle battery box is in a state of being unable to supply power to the vehicle, but other functions such as charging can be realized. That is, even if the battery box has power, the vehicle battery box cannot supply power to the vehicle when the vehicle battery box is installed on the vehicle. On the contrary, when the power supply function of the vehicle battery box is unlocked, the vehicle battery box is in a state of being able to supply power to the vehicle. That is, the vehicle battery box itself can supply power to the vehicle when the vehicle battery box is installed on the vehicle, unless the vehicle battery box itself is out of power or damaged.

[0092] In this embodiment, the locking of the power supply function of the vehicle battery box can be realized by the battery control module 121. Specifically, the battery control module 121 can be used to lock the power supply function of the vehicle battery box when the vehicle battery box is removed from the vehicle, and unlock the power supply function when a unlock command is received. Whether to unlock the power supply function of the vehicle battery box can be controlled by the vehicle battery replacement control system 11, and the unlock command can be issued by the vehicle battery replacement control system 11.

[0093] In the battery replacement operation process, the original vehicle battery box on the vehicle is removed, the battery control module 121 of the battery box system of the battery box is locked for power supply, and the new (sufficient power) vehicle battery box is installed on the vehicle. Since the power supply function of the newly installed vehicle battery box of the vehicle is originally locked, it needs to be unlocked to supply power to the vehicle. Therefore, after the vehicle battery replacement operation is completed, the battery replacement control module 111 can also be used to generate the unlock command and transmit the unlock command to the first data transmission module 112. The first data transmission module 112 is also used to send the unlock command to the second data transmission module 122 of the battery box system 12 of the newly installed vehicle battery box of the vehicle. The second data transmission module 122 of the battery box system 12 of the newly installed vehicle battery box of the vehicle is also used to receive the unlock command and transmit the unlock command to the battery control module 121 of the battery box system 12 of the newly installed vehicle battery box of the vehicle. The battery control module 121 of the battery box system 12 of the newly installed vehicle battery box of the vehicle is also used to unlock the power supply function of the newly installed vehicle battery box after receiving the unlock command.

[0094] In this embodiment, the battery box system 12 realizes the locking of the power supply function of the vehicle battery box, and the vehicle battery replacement control system 11 controls the unlocking permission, and cooperates with each other to realize the unified management of the battery box. Even if the owner privately disassembles and replaces the battery, or steals the battery of other vehicles, the disassembled battery box will be self-locked, and even if it is reassembled to the vehicle or other vehicles, it cannot supply power to the vehicle again.

[0095] Embodiment 4

[0096] The battery box data interaction method provided in this embodiment is realized by a vehicle battery replacement control system and a battery box system arranged on a vehicle battery box. The vehicle battery replacement control system is usually managed and owned by a battery replacement station or other professional institutions that can replace the battery of the vehicle. However, it should be noted that the vehicle battery replacement control system can not only work in the battery replacement station or professional institution, but also can control the vehicle battery box during vehicle driving, and can provide battery replacement services in any region such as public roads, outdoor places, etc. outside the battery replacement station or professional institution, to cope with the situation that the vehicle needs to be replaced urgently.

[0097] The vehicle battery replacement control system can be realized by a background server, or by a control circuit module installed in a battery replacement device for replacing the battery of the vehicle. The battery box system can be realized by a control circuit module of a vehicle battery box.

[0098] The vehicle battery replacement control system comprises a battery replacement control module and a first data transmission module. The battery box system comprises a battery control module and a second data transmission module. The battery replacement control module is electrically connected with the first data transmission module, and the battery control module is electrically connected with the second data transmission module. In order to realize the long-distance data transmission and signal interaction between the vehicle battery replacement control system and the battery box system, the first data transmission module and the second data transmission module are preferably connected by wireless communication, which can be but is not limited to 4G, Bluetooth and other wireless communication technologies.

[0099] As shown in Figure 3 The battery box data interaction method comprises the following steps:

[0100] Step 201: The battery replacement control module generates control information and transmits the control information to the first data transmission module.

[0101] Step 202: The first data transmission module sends the control information to the second data transmission module.

[0102] Step 203: The second data transmission module receives the control information and transmits the control information to the battery control module.

[0103] In this embodiment, the control information can include at least one of the power-off command, the power-on command, the deceleration command and the acceleration command. The battery box data interaction method can further comprise: the battery control module executes the control information after receiving the control information.

[0104] The battery replacement control module can generate the control information in response to a manual control command, or can generate the control information when a preset condition is met. The preset condition can be set by itself, for example, a deceleration command is sent to the battery control module when the vehicle is overspeed, or a power-off command is sent to the battery control module before the vehicle is replaced, etc.

[0105] The second data transmission module can be integrated in the battery control module. Alternatively, the second data transmission module can be arranged separately from the battery control module. The so-called separate arrangement means that the second data transmission module and the battery control module are realized by different chips, but the two chips can be arranged on the same circuit board or different circuit boards.

[0106] In practical applications, steps 201-203 can occur before the battery swap device swaps the battery for the vehicle, at which time the battery box system receiving the control information is designated as the battery box system provided on the original battery box of the vehicle, hereinafter referred to as the battery box system in power shortage, and the vehicle battery swap control system sends the control information to the battery box system in power shortage. After receiving the control information, the battery box system in power shortage can cooperate with or guide the vehicle battery swap control system or the battery swap device to further implement the battery swap operation.

[0107] Embodiment 5

[0108] This embodiment is a further improvement of embodiment 4. In order to cooperate with or guide the vehicle battery swap control system or the battery swap device to further implement the battery swap operation, as shown in the battery box data interaction method of the embodiment, the following steps are further performed after step 203: Figure 4

[0109] Step 204: After receiving the control information, the battery control module determines whether the battery box of the vehicle has been disconnected from the electrical connection of the vehicle. If not, the battery control module controls the battery box of the vehicle to be disconnected from the electrical connection of the vehicle.

[0110] Alternatively, in step 204, the battery control module receives the control information and directly controls the battery box of the vehicle to be disconnected from the electrical connection of the vehicle without determining. The electrical connection of the battery box of the vehicle to the vehicle includes the high-voltage and low-voltage connection between the battery box of the vehicle and the vehicle when the battery box of the vehicle supplies power to the vehicle. When the electrical connection is disconnected, both high-voltage and low-voltage need to be disconnected. The battery control module can also feed back a power-off completion command to the battery swap control module through the second data transmission module after determining that the battery box of the vehicle is disconnected from the electrical connection of the vehicle.

[0111] In this embodiment, the battery box system can further collect information of the battery box of the vehicle and upload the information to the vehicle battery swap control system. The vehicle battery swap control system can remotely detect the state of the battery box of the vehicle in real time according to the information, effectively track the state of the battery, and help to manage the battery box of the vehicle uniformly.

[0112] Specifically, the battery box data interaction method further comprises the following steps performed after step 204:

[0113] Step 205: The battery control module collects battery information of the battery box of the vehicle and transmits the battery information to the second data transmission module.

[0114] Step 206: The second data transmission module sends the battery information to the first data transmission module.

[0115] ​Step 207, the first data transmission module receives the battery information and transmits the battery information to the battery swap control module.

[0116] The battery information can specifically include battery operation information, and the battery operation information includes at least one of a previous battery swap station, a previous battery swap time, and a battery mileage. The battery information can also include battery state information, and the battery state information includes at least one of a battery voltage, a battery current, and a battery temperature.

[0117] In addition, the battery control module can be configured to collect the battery information in real time (regardless of whether the vehicle battery box is installed on the vehicle or not, or whether the installed vehicle is running or entering the battery swap station), or can be configured to collect the battery information in response to an information acquisition request received from the battery swap control module.

[0118] Of course, the battery control module can also be configured to collect the battery information of the vehicle battery box under certain conditions, such as collecting the battery information of the vehicle battery box after the vehicle is parked, or collecting the battery information of the vehicle battery box after the battery control module receives the control information, or collecting the battery information of the vehicle battery box after the battery control module receives a collection command sent by the battery control module or the vehicle battery swap control system 11 (which can be in any case). and so on.

[0119] In order to comprehensively collect various information of the vehicle battery box, the battery box system can also include a battery management system. The battery box data interaction method further includes that the battery management system stores the battery information of the vehicle battery box, and the battery control module can collect the battery information from the battery management system.

[0120] By uploading the battery information of the vehicle battery box through the battery box system, the vehicle battery swap control system can effectively master the battery state, determine whether the vehicle battery box is overheated, whether the power supply is normal, and further determine whether the vehicle battery box is intact or damaged. In addition, the vehicle battery swap control system can also upload the battery information of the vehicle battery box to a remote data center or a cloud platform, and further process and analyze the data by the remote data center or the cloud platform.

[0121] The battery control module can be integrated into the battery management system. Alternatively, the battery management system can also be separately provided with the battery control module. The so-called separate setting means that the battery control module and the battery management system are realized separately by using different chips, but the two chips can be provided on the same circuit board or different circuit boards.

[0122] The second data transmission module can be integrated in the battery management system. Alternatively, the second data transmission module can also be separately arranged from the battery control module and the battery management system. The so-called separate arrangement means that the second data transmission module is separately implemented with different chips from the battery control module and the battery management system, but the chips can be arranged on the same circuit board or different circuit boards.

[0123] In actual application, before the battery replacement equipment replaces the battery for the vehicle, the battery shortage system needs to ensure that the original vehicle battery box on the vehicle is disconnected from the vehicle, and then upload the battery information of the original vehicle battery box on the vehicle, so that the vehicle battery replacement control system can further control the battery replacement equipment to perform battery replacement operation. The specific battery replacement operation usually includes: removing the original vehicle battery box on the vehicle, and installing a new (sufficient power) vehicle battery box to the vehicle.

Considering that there are phenomena of some unqualified vehicle owners privately disassembling and replacing batteries, or stealing batteries of other vehicles, resulting in loss of high-quality battery boxes of the battery replacement station or the battery replacement site, in order to strengthen the management of the battery box, the battery box data interaction method further includes: the battery control module locks the power supply function of the vehicle battery box when the vehicle battery box is removed from the vehicle, and unlocks the power supply function when a unlocking command is received.

[0126] Specifically, after step 207, as shown in Figure 5 The battery box data interaction method further includes:

[0127] Step 208, the vehicle battery replacement control system controls the battery replacement equipment to perform battery replacement operation. The specific battery replacement operation usually includes: removing the original vehicle battery box on the vehicle, and installing a new (sufficient power) vehicle battery box to the vehicle. The battery control module of the battery shortage system locks the power supply function of the vehicle battery box when the vehicle battery box is removed from the vehicle.

[0128] Step 209, after the vehicle battery replacement operation is completed, the battery replacement control module generates the unlocking command and transmits the unlocking command to the first data transmission module.

[0129] Step 210, the first data transmission module sends the unlocking command to the second data transmission module of the battery box system of the newly installed vehicle battery box of the vehicle.

[0130] Step 211, the second data transmission module of the battery box system of the newly installed vehicle battery box of the vehicle receives the unlocking command and transmits the unlocking command to the battery control module of the battery box system of the newly installed vehicle battery box of the vehicle.

[0131] Step 212, the battery control module of the battery box system of the newly installed battery box of the vehicle unlocks the power supply function of the newly installed battery box after receiving the unlocking command.

[0132] In this embodiment, the battery box system realizes the locking of the power supply function of the battery box, and the vehicle battery replacement control system controls the unlocking authority, and cooperates with each other to realize the unified management of the battery box. Even if the owner privately replaces the battery or steals the battery of other vehicles, the disassembled battery box will be self-locked, and even if it is reassembled to the vehicle or other vehicles, it cannot supply power to the vehicle again.
