[0025] In order to solve the technical problem of poor reliability of automobile battery replacement control in the prior art, the present application provides a vehicle controller, method, system and automobile for automobile battery replacement, which can achieve the effect of improving the reliability of automobile battery replacement control.

[0026] Figure 1 A control flow chart of a battery-swap vehicle controller provided in an embodiment of the present application, such as Figure 1 As shown, including:

[0027] S101, controlling the interaction component to perform information interaction with the battery swap station so that the battery swap station determines the vehicle status of the vehicle;

[0028] S102, when the vehicle state is that battery replacement is allowed, controlling the first battery pack to perform self-checking, lowering high voltage power, and cutting off low voltage power in preparation for battery replacement;

[0029] S103, after the first battery pack of the car is replaced with the second battery pack at the battery swap station, the second battery pack is subjected to low voltage, self-inspection, and high voltage control to operate the car, wherein some main control functions and logics in the first battery pack and the second battery pack are integrated into the battery swap vehicle controller.

[0030] The car mentioned in the above-mentioned battery-swap vehicle controller can be a new energy vehicle with a detachable battery pack, which is used to provide energy to the car to enable the car to move.

[0031] The above-mentioned battery swap station is a place for replacing the battery pack of a car. The battery swap station is equipped with replaceable battery packs. When the car drives to the battery swap station, the battery pack on the car can be removed and replaced with the battery pack of the battery swap station. The battery pack in the battery swap station has more remaining power. Therefore, by replacing the battery pack at the battery swap station, the empty battery can be replaced with a fully charged battery.

[0032] The above-mentioned battery swap vehicle controller can be a car's control chip, or a system and instructions integrated on the control chip. The battery swap vehicle controller is responsible for controlling the power supply of the battery pack on the vehicle, the startup of electronic devices, and the communication with the battery swap station.

[0033] In the above step S101, information can be exchanged with the battery swap station through the interactive component of the battery swap vehicle controller. The interactive component can be a physical component or a virtual component. When the user drives the car into the battery swap station, for example, when it enters a certain range of the battery swap station, the battery swap controller on the car interacts with the battery swap station to allow the battery swap station to determine the car status of the car. Alternatively, the battery swap station can also be equipped with cameras, sensors, etc. When the car is photographed entering the battery swap station, or when the car is sensed to enter the battery swap station, it interacts with the battery swap controller on the car to determine the information and status of the car.

[0034] The battery swap station determines the vehicle status of the vehicle, which can be used to determine whether the vehicle is allowed to swap batteries. The vehicle status can include multiple states, such as identity status, vehicle condition status, etc. The identity status can be whether the vehicle is registered and whether it is eligible for battery swapping. The vehicle condition status can be whether the vehicle needs to swap batteries, whether the vehicle is normal, and whether battery swapping can be performed.

[0035] In the above step S102, when the vehicle status is that battery replacement is allowed, the first battery pack is controlled to perform self-inspection, reduce high voltage power, and cut off low voltage power for battery replacement preparation; the control interface of the first battery pack can be called to obtain the status information of the first battery pack; according to the status information of the first battery pack, the high-voltage relay of the first battery pack is disconnected to make the first battery pack exit the high-voltage state, and the low-voltage driving power supply is disconnected after the exit from the high-voltage state, so that the first battery pack is completely powered off and enters a dormant state.

[0036] In the above step S103, after the battery swap station replaces the first battery pack of the car with the second battery pack, it performs low voltage power-up, self-test, high voltage control, etc. on the second battery pack to operate the car. Among them, some main control function logics in the first battery pack and the second battery pack are integrated into the battery swap vehicle controller, which can directly control the power-up and power-down, battery swap control, charging control, diagnostic services and OTA upgrades of the battery.

[0037] When the battery swap station determines the vehicle status of the car and confirms that the car can be replaced, it can send instructions to the car to prepare for battery replacement. The car can be ready for battery replacement when the car enters a specific position and the various components on the car enter a specific state, such as locking the doors, locking the steering wheel, and putting the gear in neutral. The battery swap vehicle controller controls the vehicle control to block the safety strategy of opening the door and automatically entering the P gear when the high voltage is lowered. At the same time, the car's lights, wipers, and multimedia functions are turned off; and the first battery pack is controlled to perform self-inspection, lower high voltage, and cut off low voltage power replacement preparations; then, the battery swap station replaces the car, removes the first battery pack from the car, and puts in the second battery pack.

[0038] After the car's first battery pack is replaced with the second battery pack at the battery swap station, the battery swap state is exited; the battery swap vehicle controller controls the second battery pack to increase low voltage, self-check, increase high voltage, etc., so that the car can be driven; at the same time, the vehicle is controlled to restore the safety strategy of opening the door and automatically entering the P gear with low voltage, restore the car's lights, wipers, and multimedia functions, and update the car's remaining mileage and remaining power status.

[0039] Let's take an example. A user drives a new energy vehicle into a battery swap station, and the new energy vehicle is equipped with a first battery pack. When the user drives into the battery swap station, the battery swap station can detect the new energy vehicle through wireless Bluetooth information interaction, cameras, sensors and other facilities, such as detecting the license plate or the vehicle's unique identification, to check the vehicle status of the new energy vehicle. The vehicle status may include identity status, vehicle condition status, etc. The identity status may include whether the vehicle has been registered, whether it is eligible for battery swap, and vehicle condition status may include whether the vehicle needs to be replaced, whether the vehicle is normal, whether it can be replaced, etc. When the vehicle status is detected and it is determined that the vehicle can be replaced, the owner needs to control the vehicle according to the instructions. The instructions may be prompting the vehicle to move to a specific location, or prompting the vehicle to close the door, shift to neutral, lock the steering wheel, etc. If it is an autonomous vehicle, the owner can also get off the vehicle, and the vehicle will automatically replace the battery according to the instructions of the battery swap station. When the vehicle moves to the correct location and can be replaced, the battery swap station can be replaced by mechanical automation, remove the first battery pack, place it in the battery swap station for charging, and install the fully charged second battery pack on the new energy vehicle, thereby completing the battery pack replacement. When the battery pack is replaced, the new energy vehicle can control the second battery pack to supply power to the vehicle's electronic equipment or power system, and the user can drive the car away from the battery swap station.

[0040] In this application, some main control functions in the first battery pack and the second battery pack are integrated into the battery swap vehicle controller, which can directly control the power on and off of the battery, battery swap control, charging control, diagnostic services and OTA upgrades, etc. It can replace the existing technology such as the battery swap dedicated gateway GW that separately transmits battery status information to adapt to the vehicle product lines under different EE architecture platforms of different OEMs. It is no longer the way for traditional new energy vehicles to indirectly control the power battery BMS through VCU.

[0041] This application uses a battery swap vehicle controller equipped with interactive components to directly exchange information between the power battery information of the vehicle and battery pack and the battery swap station, replacing the "battery swap TBOX" controller of the mainstream solution on the market. The battery swap vehicle controller directly realizes the battery swap function with the battery swap station, shortens the control link, improves reliability, and reduces costs.

[0042] In one example, in the above step S102, when the vehicle status is to allow battery replacement, the first battery pack is controlled to perform self-inspection, reduce high voltage power, and cut off low voltage power in preparation for battery replacement, which can be to call the control interface of the first battery pack to obtain the status information of the first battery pack; according to the status information of the first battery pack, the high-voltage relay of the first battery pack is disconnected to make the first battery pack exit the high-voltage state, and the low-voltage driving power supply is disconnected after the exit from the high-voltage state, so that the first battery pack is completely powered off and enters a sleep state.

[0043] In one example, in order to better replace the battery, when the second battery pack is controlled after the battery pack is replaced in the above step S103, the control interface of the second battery pack can be called to obtain the status information of the second battery pack; the second battery pack can be controlled according to the status information of the second battery pack to enable the second battery pack to supply power. For example, the low-voltage hard-line wake-up interface is driven to enable the second battery pack to enter a low-voltage working state; the control interface of the second battery pack is called to obtain the status information of the second battery pack and guide its self-test; the high-voltage relay of the second battery pack is controlled to close and open in sequence according to the status information of the second battery pack to enable the second battery pack to enter a high-voltage power supply state.

[0044] In this embodiment, both the first battery pack and the second battery pack mentioned above can have built-in control interfaces, and the control interfaces can be given to the battery swap vehicle controller for the battery swap vehicle controller to call. For example, the battery pack in this embodiment has a built-in battery management system, which is mainly responsible for monitoring the status of the battery pack, and exposing the interface for controlling and managing the battery pack to the new energy vehicle where the battery pack is located, and is used by the battery swap vehicle controller of the new energy vehicle. The purpose of this embodiment is that the battery swap vehicle controller integrates the control functions and logic of the battery, so the battery swap vehicle controller of the new energy vehicle can directly call the battery pack to control the battery pack.

[0045] In one example, when controlling the battery pack, a control instruction set of the battery management system can be determined according to the status information of the battery pack; and control instructions are sent to the battery management system according to the control instruction set to control the power supply of the battery pack.

[0046] In one example, if Figure 2 As shown in the figure, when replacing the battery pack of a car, the battery replacement vehicle controller can perform the following steps:

[0047] S201, before the battery swap starts, the battery swap vehicle controller controls the vehicle to open the door and automatically enter the P gear with high voltage, and at the same time, the car's lights, wipers, and multimedia functions are turned off;

[0048] S202, receiving a battery swap command from the battery swap station to enter a battery swap state, and controlling the first battery pack to perform self-checking, high voltage power reduction, and low voltage power reduction preparation work;

[0049] S203, after replacing the first battery pack of the vehicle with the second battery pack, exit the battery replacement state; the battery replacement vehicle controller performs low voltage, self-check, and high voltage control on the second battery pack, so that the vehicle can reach a drivable state;

[0050] S204, the battery-swap vehicle controller controls the vehicle to restore the safety strategy of opening the door and automatically entering the P gear under high voltage, restores the car's lights, wipers, and multimedia functions, and updates the car's remaining mileage and remaining power status.

[0051] In this embodiment, when the battery pack of the car is replaced, in order to ensure that the battery swap station can adjust the vehicle to the appropriate position, the battery swap vehicle controller needs to shield the safety strategy of automatically entering the P gear such as opening the door and lowering the high voltage, and the vehicle needs to be in a non-electronic parking state. In order to avoid the impact of power loss on the small battery of the car, the car's lights, wipers, and multimedia functions can be controlled to be turned off, such as music playback function, radio, etc. During the battery swap process, the battery swap progress can be displayed on the user's mobile phone. For example, the battery swap progress can be displayed by an animated image showing that the first battery pack is removed and the second battery pack is installed, etc., or the progress can be displayed by a progress bar or a percentage number. When the battery swap is completed, the car exits the battery swap state and updates the remaining mileage and remaining power status of the car. At the same time, the car's lights, wipers, and multimedia functions that are turned off are restored. It should be noted that if the lights, wipers, etc. are in a closed state, they are also in a closed state when the battery is swapped. After the battery is swapped, they can remain in a closed state and open again after receiving the opening signal. The purpose of doing this is to reduce the low-voltage power consumption during the battery replacement process, and to ensure that the vehicle will not be overpowered by the small battery due to special circumstances such as battery replacement failure, which causes the low-voltage power consumption of the entire vehicle to be too high and the inability to replenish power.

[0052] In one example, if Figure 3As shown, when the control interaction component interacts with the battery swap station, the following steps can be performed:

[0053] S301, sending the vehicle information of the vehicle to the battery swap station through the battery swap vehicle controller, and the battery swap station uploads the vehicle information to the cloud; wherein the cloud is used to identify the vehicle information to determine whether the vehicle is allowed to be battery swapped;

[0054] S302, when the vehicle status is that battery swapping is allowed, the battery swapping vehicle controller receives the battery swapping preparation instruction returned by the battery swapping station to prepare for battery swapping. When the vehicle status is that battery swapping is prohibited, the battery swapping vehicle controller receives the departure instruction returned by the battery swapping station to leave the battery swapping station.

[0055] In this embodiment, when a car enters a battery swap station, the battery swap vehicle controller can interact with the battery swap station. The battery swap vehicle controller can send messages to the battery swap station through Bluetooth, near-field communication, etc., and send the car information to the battery swap station. After receiving the car information, the battery swap station uploads the car information to the cloud for verification. For example, based on vehicle information such as the license plate number or unique identification number of the car, the owner's information can be verified in the cloud to check whether the owner has the authority to swap the battery. If the user's car can be swapped, the cloud sends a message to the battery swap station. After receiving the message, the battery swap station can swap the car. If the car information is verified and it is found that the car cannot be swapped, a message is sent to the car, or the battery swap station notifies, indicating that the battery cannot be swapped, and requiring the car to leave or adjust the status until the battery can be swapped.

[0056] This embodiment verifies the vehicle status of the vehicle and can authenticate the identity of the vehicle that applies for battery replacement, so that vehicles that do not have identity authority to replace the battery are not allowed to replace the battery, and vehicles that are allowed to replace the battery can replace the battery, thereby ensuring the safety and stability of the battery replacement.

[0057] In one example, if Figure 4 As shown, when the state of the above-mentioned vehicle is to allow battery replacement, the above-mentioned battery replacement vehicle controller receives the battery replacement preparation instruction returned by the above-mentioned battery replacement station to prepare for battery replacement, including:

[0058] S401, adjusting the position of the above-mentioned vehicle to a battery replacement position;

[0059] S402, controlling the doors, steering wheel, handbrake and gear position of the above-mentioned automobile to be in a battery replacement state.

[0060] That is to say, if the car allows battery swapping, a message can be sent to the battery swapping vehicle controller, or a broadcast can be made at the battery swapping station to allow the car to move to the correct position and adjust the status of its own doors, steering wheel, handbrake, gear position, etc. to a mode that allows battery swapping, thereby performing the battery swap.

[0061] In this embodiment, the user can control or adjust the state of the car according to the broadcast of the battery swap station. If it is automatic driving, the car can be automatically adjusted according to the instructions sent by the battery swap station.

[0062] In one example, the battery-swapping vehicle controller may be a vehicle electronic controller (Vehicular Communication Unit, VCU) of a new energy vehicle. In addition to the battery-swapping function, the VCU may also have other functions, such as acting as a vehicle controller to control other controllers and sub-controllers on the vehicle. Figure 5 Schematic diagram of battery replacement in this embodiment. Figure 5 As shown, the vehicle side of the new energy vehicle may also include a first battery pack (including a battery management system (BMS)), an integrated brake control unit (iBCU), an electric power steering system (EPS), a body control module (BCM), and an intelligent head unit (iHU). Each system / controller is controlled by the vehicle control system and interacts with the vehicle control system.

[0063] The battery swap station includes a station Bluetooth module (Station Bluetooth low energy, SBLE), which communicates with the vehicle Bluetooth module (Vehicle Bluetooth low energy, VBLE) integrated in the battery swap vehicle controller to exchange vehicle information. The controller of the battery swap station is responsible for the control of the entire battery swap process and the charging process, and is responsible for the battery swap mileage billing. Cloud platform 1 is a cloud data platform where the battery swap station uploads the battery swap information through 4G cellular network communication. It is used for the operation and management of batteries and battery swap stations, monitoring of battery swap processes and user payments, etc. Cloud platform 2 is a vehicle-side cloud data platform that can monitor vehicle operation and battery swap status. The cloud data of cloud platforms 1 and 2 realizes information interaction with end customers and visualization of the battery swap process through the user-side APP.

[0064] The battery-swap vehicle controller VCU, in addition to controlling the high-voltage power on and off of the vehicle and the gear status of the vehicle, also integrates the battery swap function. The main functions are: Function 1: Collecting basic information on the power battery status of the battery pack, fault diagnosis information, and the cumulative charge and discharge power of the battery pack; Function 2: Collecting vehicle status, such as gear control, brake status, steering wheel angle, etc.; Function 3: Matching and executing the high-voltage power on and off processes and strategies of the battery for different automotive electronic and electrical architectures (Electrical / Electronic Architecture, EE architecture) and different vehicles; Function 4: Information exchange with the SBLE of the battery swap station through the wireless Bluetooth module, such as vehicle status information, whether high voltage is allowed, battery swap status, etc.; Function 5: Collecting the status and fault information of the battery swap mechanism; Function 6: Accepting instructions from the battery swap station during the battery swap process, such as executing unlocking and locking actions of the battery swap mechanism. Each function is executed using a processing module, or a processing module can also execute multiple functions. Taking a function executed by a processing module as an example, Figure 6 It is a schematic diagram of the processing modules of the battery swap vehicle controller. The first processing module to the sixth processing module implement functions one to six respectively.

[0065] In this embodiment, when replacing the battery, the first step is to compare and verify the vehicle information. When the user drives the vehicle into the battery swap station, the camera of the battery swap station captures the license plate and transmits it to the cloud platform for license plate comparison. If the license plate is legal, the cloud platform will issue an opening command and the corresponding vehicle information. After receiving the command, the station control establishes Bluetooth communication with the vehicle and sends a battery swap preparation command to the vehicle. After receiving the command, the vehicle sends the collected vehicle status information and the basic information of the battery swap pack to the station control via Bluetooth communication. The station control verifies the information. If the information verification is qualified, it enters the vehicle position and status verification link. If it fails, the battery swap process is terminated and the user is prompted to leave the battery swap station.

[0066] For the vehicle position and status verification link, the station control confirms the vehicle position and status. First, it must confirm that the battery swap vehicle's freedom verification is qualified. If it fails, the user must be prompted to adjust and close the door, return the steering wheel to the center position, release the handbrake, and adjust the gear to the parking gear P or N gear. After the freedom verification is qualified, the battery swap station can fine-tune the vehicle position to ensure that the vehicle slides into the positioning slot to ensure efficient and accurate matching of the vehicle's battery swap mechanism and the battery swap cart.

[0067] For the vehicle lowering high voltage link, when the station control determines that the vehicle is in place, it sends a request to lower the high voltage to the vehicle. After receiving the request, the battery swapping vehicle controller enters the battery swapping state. At this time, the vehicle needs to stop automatically entering P and other safety strategies. The vehicle lowering high voltage process is executed synchronously. After the high voltage is lowered, the battery swapping battery pack needs to perform the low voltage action. At the same time, the vehicle iHU receives the battery swapping status, and the vehicle screen calls the battery swapping APP to synchronously display the vehicle's battery swapping process, and synchronously disables multimedia functions such as music and video under the vehicle domain control; BCM receives the battery swapping status and also needs to disable the lights, wipers and other functions under the body domain control. This method can reduce the low-voltage power consumption during the battery swapping process and ensure that the vehicle will not be fed by the small battery due to special circumstances such as battery swapping failures where the low-voltage power consumption of the vehicle is too high and the high-voltage DCDC cannot be replenished.

[0068] For the automatic battery replacement process, when the station control receives feedback from the battery replacement vehicle controller that the vehicle has reached high voltage and the battery pack has reached low voltage, the station control sends a battery replacement mechanism unlocking command to the battery replacement vehicle controller. When the battery pack quick-change mechanism is unlocked, the automatic battery replacement vehicle can be operated to perform the battery replacement operation. When the new battery pack is replaced in place, the station control sends a locking command again. After confirming that the battery replacement mechanism is locked, the battery pack replacement is completed.

[0069] For the high-voltage link of the vehicle, when the battery-swap vehicle controller receives the battery-swap completion status sent by the station control, it needs to update the vehicle's battery-swap status and the vehicle's remaining driving range. The iHU will simultaneously update the battery-swap status on the vehicle's battery-swap APP. After the battery-swap vehicle controller receives the vehicle's high-voltage request, it executes the high-voltage power-on process and enters the READY driving state based on the vehicle's status. When the vehicle is high-voltage, iHU and BCM can restore low-voltage power functions such as multimedia entertainment applications, lights, and wipers. Only then can the user drive the vehicle out of the battery-swap station.

[0070] This embodiment can also manually replace the battery. If the station fails to replace the battery three times in the automatic battery replacement state, the automatic battery replacement process will be stopped. The manual battery replacement device can be used to manually replace the battery of the vehicle. After the battery replacement is completed, the station control needs to manually control the vehicle battery replacement status and high voltage command. After receiving the command, the vehicle can be powered on normally and enter the drivable state.

[0071] This application ensures the safety of the battery replacement process while improving the accuracy and automation of battery replacement control. Efficient battery replacement saves users waiting time. The vehicle computer can explicitly prompt users of the battery replacement status and avoid special situations such as small battery feeding during battery replacement and the inability of the vehicle to automatically go to high voltage due to battery replacement failure. At the vehicle level, the power battery management main control module, Bluetooth module, and battery replacement information interaction are integrated in the VCU or other domain controllers. The controller has a high degree of integration, which not only has cost advantages, but also further improves communication reliability and the effectiveness of control of battery replacement batteries and battery replacement stations. It is conducive to the transplantation and platform development of battery replacement technology for vehicles with different EE architectures and different series products. Secondly, this battery replacement solution can liberate the platform development freedom of battery replacement batteries. The battery charging and discharging process, fault diagnosis and processing, internal and external communications, startup program BOOT development, unified diagnostic services (UDS) services and diagnostic trouble codes (DTC) can be modularly copied to develop a platform-based development of universal battery replacement solutions.

[0072] This embodiment also provides a method for replacing battery in an automobile. Figure 7 As shown, including:

[0073] S701, the battery swap vehicle controller collects vehicle status information and universal battery pack information through CAN communication and its own hard-wired interface, and exchanges information with the battery swap station through wireless Bluetooth.

[0074] S702, after the battery swap station determines the information of the car, it compares the information with the cloud to identify the car information to determine whether the car is allowed to swap batteries; if the car status fed back by the cloud is that battery swap is prohibited, the vehicle user needs to leave the battery swap station; if the car status is that battery swap is allowed, the vehicle starts to prepare for battery swap;

[0075] S703, when the vehicle status is that battery swapping is allowed, the battery swapping vehicle controller controls the vehicle to open the door and automatically enter the P gear with high voltage, and at the same time, the vehicle's lights, wipers, and multimedia functions are turned off; and the first battery pack is controlled to perform self-checking, high voltage power, low voltage power, and other preparations for battery swapping;

[0076] S704, after replacing the first battery pack of the car with the second battery pack at the battery swap station, exit the battery swap state; the battery swap vehicle controller controls the second battery pack to increase low voltage, self-check, increase high voltage, etc., so that the car can be driven; at the same time, the vehicle is controlled to restore the safety strategy of opening the door and automatically entering the P gear with low voltage, restore the car's lights, wipers, and multimedia functions, and update the car's remaining mileage and remaining power status.

[0077] The car mentioned in the above-mentioned car battery replacement method can be a new energy car. The car has a detachable battery pack, and the battery pack is used to provide energy to the car to enable the car to move.

[0078] The above-mentioned battery swap station is a place for replacing the battery pack of a car. The battery swap station is equipped with replaceable battery packs. When the car drives to the battery swap station, the battery pack on the car can be removed and replaced with the battery pack of the battery swap station. The battery pack in the battery swap station has more remaining power. Therefore, by replacing the battery pack at the battery swap station, the empty battery can be replaced with a fully charged battery.

[0079] The above-mentioned battery swap vehicle controller can be a car's control chip, or a system and instructions integrated on the control chip. The battery swap vehicle controller is responsible for controlling the power supply of the battery pack on the vehicle, the startup of electronic devices, and the communication with the battery swap station.

[0080] In the above-mentioned battery swapping process, the interactive components of the above-mentioned battery swapping vehicle controller can interact with the battery swapping station. The interactive components can be physical components or virtual components. When the user drives the car into the battery swapping station, for example, when driving into a certain range of the battery swapping station, the battery swapping controller on the car interacts with the battery swapping station to allow the battery swapping station to determine the car status. Alternatively, the battery swapping station can also be equipped with cameras, sensors, etc. When the car is photographed entering the battery swapping station, or when the car is sensed to enter the battery swapping station, it interacts with the battery swapping controller on the car to determine the information and status of the car.

[0081] The battery swap station determines the vehicle status of the vehicle, which can be used to determine whether the vehicle is allowed to swap batteries. The vehicle status can include multiple states, such as identity status, vehicle condition status, etc. The identity status can be whether the vehicle is registered and whether it is eligible for battery swapping. The vehicle condition status can be whether the vehicle needs to swap batteries, whether the vehicle is normal, and whether battery swapping can be performed.

[0082] When the state of the above-mentioned automobile is to allow battery replacement, the first battery pack of the above-mentioned automobile is replaced with the second battery pack through the above-mentioned battery replacement station, wherein some main control functions and control logics in the first battery pack and the second battery pack are integrated into the battery replacement vehicle controller, so that the battery replacement controller can directly control the battery packs before and after replacement.

[0083] When the battery swap station determines the vehicle status of the car and confirms that the car can be replaced, it can send instructions to the car to prepare for battery replacement. The car can be ready for battery replacement when the car enters a specific position and the various components on the car enter a specific state, such as locking the doors, locking the steering wheel, and putting the gear in neutral. The battery swap vehicle controller controls the vehicle control to block the safety strategy of opening the door and automatically entering the P gear when the high voltage is lowered. At the same time, the car's lights, wipers, and multimedia functions are turned off; and the first battery pack is controlled to perform self-test, lower high voltage, cut off low voltage and other battery replacement preparations; then, the battery swap station replaces the car, removes the first battery pack from the car, and puts in the second battery pack.

[0084] After the car's first battery pack is replaced with the second battery pack at the battery swap station, the battery swap state is exited; the battery swap vehicle controller controls the second battery pack to increase low voltage, self-check, increase high voltage, etc., so that the car can be driven; at the same time, the vehicle is controlled to restore the safety strategy of opening the door and automatically entering the P gear with low voltage, restore the car's lights, wipers, and multimedia functions, and update the car's remaining mileage and remaining power status.

[0085] Let's take an example. A user drives a new energy vehicle into a battery swap station, and the new energy vehicle is equipped with a first battery pack. When the user drives into the battery swap station, the battery swap station can detect the new energy vehicle through wireless Bluetooth information interaction, cameras, sensors and other facilities, such as detecting the license plate or the vehicle's unique identification, to check the vehicle status of the new energy vehicle. The vehicle status may include identity status, vehicle condition status, etc. The identity status may be whether it has been registered, whether it is eligible for battery swap, and the vehicle condition status may be whether the vehicle needs to be replaced, whether the vehicle is normal, whether it can be replaced, etc. When the vehicle status is detected and it is determined that the vehicle can be replaced, the owner needs to control the vehicle according to the instructions. The instructions may be to prompt the vehicle to move to a specific location, or to prompt the vehicle to close the door, put it in neutral, lock the steering wheel, etc. If it is an autonomous vehicle, the owner can also get off the vehicle, and the vehicle will automatically replace the battery according to the instructions of the battery swap station. When the vehicle moves to the correct location and can be replaced, the battery swap station can be replaced by mechanical automation, remove the first battery pack, place it in the battery swap station for charging, and install the fully charged second battery pack on the new energy vehicle, thereby completing the battery pack replacement. When the battery pack is replaced, the new energy vehicle can control the second battery pack to supply power to the vehicle's electronic equipment or power system, and the user can drive the car away from the battery swap station.

[0086] This application uses a battery swap vehicle controller equipped with interactive components to directly exchange information between the power battery information of the vehicle and battery pack and the battery swap station, replacing the "battery swap TBOX" controller of the mainstream solution on the market. The battery swap vehicle controller directly realizes the battery swap function with the battery swap station, shortens the control link, improves reliability, and reduces costs.

[0087] Figure 8 is a schematic diagram of a vehicle battery replacement system of the present application, such as Figure 8 As shown, including:

[0088] The vehicle end 801 includes at least a battery swap vehicle controller and a universal battery pack. The battery swap vehicle controller transmits information and implements functions and controls functions with the universal battery pack and other vehicle controllers through CAN communication, and uses wireless Bluetooth technology to interact with the battery swap station so that the battery swap station can determine the vehicle status of the vehicle. The universal battery pack interacts with the battery swap vehicle controller through CAN communication, and is compatible with at least two types of vehicles.

[0089] The battery swap station end 802 exchanges vehicle status information with the battery swap vehicle controller through wireless Bluetooth technology; exchanges battery swap status information with the cloud through 4G cellular network communication; and has the battery swap control capability to replace the first battery pack of the car with the second battery pack.

[0090] The car mentioned in the above-mentioned car battery replacement system can be a new energy car. The car has a detachable battery pack, and the battery pack is used to provide energy to the car to enable the car to move.

[0091] The above-mentioned battery swap station is a place for replacing the battery pack of a car. The battery swap station is equipped with replaceable battery packs. When the car drives to the battery swap station, the battery pack on the car can be removed and replaced with the battery pack of the battery swap station. The battery pack in the battery swap station has more remaining power. Therefore, by replacing the battery pack at the battery swap station, the empty battery can be replaced with a fully charged battery.

[0092] The above-mentioned battery swap vehicle controller can be a car's control chip, or a system and instructions integrated on the control chip. The battery swap vehicle controller is responsible for controlling the power supply of the battery pack on the vehicle, the startup of electronic devices, and the communication with the battery swap station.

[0093] In the above-mentioned battery swapping process, the interactive components of the above-mentioned battery swapping vehicle controller can interact with the battery swapping station. The interactive components can be physical components or virtual components. When the user drives the car into the battery swapping station, for example, when driving into a certain range of the battery swapping station, the battery swapping controller on the car interacts with the battery swapping station to allow the battery swapping station to determine the car status. Alternatively, the battery swapping station can also be equipped with cameras, sensors, etc. When the car is photographed entering the battery swapping station, or when the car is sensed to enter the battery swapping station, it interacts with the battery swapping controller on the car to determine the car information and status.

[0094] The battery swap station determines the vehicle status of the vehicle, which can be used to determine whether the vehicle is allowed to swap batteries. The vehicle status can include multiple states, such as identity status, vehicle condition status, etc. The identity status can be whether the vehicle is registered and whether it is eligible for battery swapping. The vehicle condition status can be whether the vehicle needs to swap batteries, whether the vehicle is normal, and whether battery swapping can be performed.

[0095] When the state of the above-mentioned automobile is to allow battery replacement, the first battery pack of the above-mentioned automobile is replaced with the second battery pack through the above-mentioned battery replacement station, wherein the control logic in the first battery pack and the second battery pack is integrated into the battery replacement vehicle controller, so that the battery replacement controller can directly control the battery packs before and after replacement.

[0096] When the battery swap station determines the state of the car and confirms that the car can be replaced, it can send instructions to the car to prepare for battery replacement. The car can be ready for battery replacement when the car enters a specific position and the various components on the car enter a specific state, such as locking the doors, locking the steering wheel, and shifting the gear to neutral. Then, the battery swap station replaces the car, removes the first battery pack from the car, and inserts the second battery pack.

[0097] Since some main control functions and control logic of the first battery pack and the second battery pack are integrated into the battery swap vehicle controller, the battery packs can be directly replaced by replacing an empty battery pack with a fully charged battery pack, and the replaced battery pack can be controlled by the battery swap controller.

[0098] Since the first battery pack on the car is removed and the second battery pack is installed, the second battery pack can be used to supply energy for the car.

[0099] Let's take an example. A user drives a new energy vehicle into a battery swap station, and the new energy vehicle is equipped with a first battery pack. When the user drives into the battery swap station, the battery swap station can detect the new energy vehicle through facilities such as cameras and sensors, such as detecting the license plate or the unique identification of the vehicle, to check the vehicle status of the new energy vehicle. The vehicle status may include identity status, vehicle condition status, etc. The identity status may be whether it has been registered, whether it is eligible for battery swap, and the vehicle condition status may be whether the vehicle needs to be replaced, whether the vehicle is normal, whether it can be replaced, etc. When the vehicle status is detected and it is determined that the vehicle can be replaced, an instruction can be sent to the vehicle. The instruction may be to prompt the vehicle to move to a specific location, or to prompt the vehicle to close the door, shift to neutral, lock the steering wheel, etc. The owner only needs to control the vehicle according to the prompt. If it is an autonomous vehicle, the owner can also get off the vehicle, and the vehicle will automatically replace the battery according to the instructions of the battery swap station. When the vehicle moves to the correct location and can be replaced, the battery swap station can replace the battery manually or mechanically, remove the first battery pack, place it at the battery swap station for charging, and install the fully charged second battery pack on the new energy vehicle, thereby completing the battery pack replacement. When the battery pack is replaced, the new energy vehicle can control the second battery pack to supply power to the vehicle's electronic equipment or power system, and the user can drive the car away from the battery swap station.

[0100] This application uses a battery swap vehicle controller equipped with interactive components to directly exchange information between the power battery information of the vehicle and battery pack and the battery swap station, replacing the "battery swap TBOX" controller of the mainstream solution on the market. The battery swap vehicle controller directly realizes the battery swap function with the battery swap station, shortens the control link, improves reliability, and reduces costs.

[0101] This embodiment also provides a car, which is equipped with the above-mentioned battery-swap vehicle controller, or executes the above-mentioned battery-swap control method, or is the car end in the above-mentioned battery-swap control system.

[0102] The above-mentioned car can be a new energy car, and the car has a detachable battery pack, and the battery pack is used to provide energy to the car so that the car can move.
