S210: When the electric device arrives at the battery swap station, obtain the status information of the battery on the electric device.

S220: Determine whether to replace the battery at a battery replacement station based on the status information of the battery.

Optionally, the electrical device can be a vehicle, and in the future, it may also be a device as small as a robot or as large as a ship or airplane that uses batteries to provide power or power. The embodiments of this application do not limit the electrical devices.

First of all, it should be noted that the electrical device can be equipped with one battery or multiple batteries. When the electrical device is equipped with multiple batteries, the station control system can obtain status information of at least one battery among the multiple batteries. In one example, the station control system can determine whether to replace the battery at the battery swap station based on the status information of the at least one battery. In other words, as long as a battery on the power-consuming device has a fault that affects battery replacement, it is determined that the battery will not be replaced at the battery swap station. In another example, the station control system may also determine whether to replace the at least one battery at the battery swap station based on the status information of the at least one battery. In other words, if the battery on the electrical device is faulty, that battery will not be replaced, and other batteries without faults can be replaced normally.

Therefore, the battery replacement method provided by the embodiments of the present application determines whether to replace the battery at a power swap station based on the status information of the battery on the electrical device before the battery replacement. The method of the embodiments of the present application can diagnose the battery in advance, so It is helpful to avoid the situation of disassembling the battery from the electrical device and then returning it, thereby helping to improve the efficiency of battery replacement.

Optionally, in an embodiment of the present application, the status information of the battery includes fault information of the battery.

According to the status information of the battery, it is determined whether to replace the battery at a battery swap station, including: when the fault occurs If the message indicates that the battery is faulty, make sure not to replace the battery at a battery swap station.

Normally, the battery management unit (for example, MBMU or SBMU) on the electrical device will detect the battery status in real time. When a battery failure is detected, the fault code table will be queried to generate a fault code (that is, fault information), and stored in In the storage unit on the electrical device. When the power-consuming device arrives at the battery swap station, the station control system can directly or indirectly obtain the fault code stored in the storage unit on the power-consuming device, and then the station control system determines whether to replace the battery based on the fault code.

When it comes to batteries, failures can be big or small. Some faults may affect battery replacement, while other faults may not affect battery replacement. The station control system will determine not to replace the battery only if it determines that the battery on the electrical device has a fault that affects battery replacement. On the contrary, if the fault of the battery on the electrical device does not affect the battery replacement, the station control system will determine to replace the battery. For example, if the fault of the battery is a first-level fault, it can be considered that the fault is a fault that affects battery replacement, and the station control system can determine not to replace the battery; for another example, if the fault of the battery is a second-level fault, it can be considered that the fault is a fault that affects battery replacement. The fault is a fault that does not affect battery replacement. The station control system can determine battery replacement.

In this embodiment, fault information is used to explicitly indicate the fault of the battery, so that the station control system can directly use the fault information to determine whether to replace the battery. Therefore, the complexity of the logical judgment of the station control system is reduced.

Optionally, in another embodiment of the present application, the status information of the battery includes parameter information of the battery. The parameter information includes at least one of power, voltage and temperature. According to the status information of the battery, it is determined whether to replace the battery at a battery swap station. , including: determining the fault of the battery based on the parameter information of the battery; determining whether to replace the battery at the battery swap station based on the fault of the battery.

Specifically, the battery management unit (eg, MBMU or SBMU) on the electrical device also monitors various parameter information of the battery in real time, such as at least one of power, voltage, and temperature. When the electrical device arrives at the battery swap station, the station control system can directly or indirectly obtain various parameter information monitored by the battery management unit on the electrical device. The station control system can determine the current fault of the battery based on the obtained battery parameter information; and then the station control system determines whether to replace the battery based on the current fault of the battery. For example, if the station control system determines that the current fault of the battery is a first-level fault based on the battery parameter information, it can be considered that the fault is a fault that affects battery replacement, so it can be determined not to replace the battery; for another example, the station control system determines based on the battery According to the parameter information, it is determined that the current fault of the battery is a secondary fault, then the fault can be considered to be a fault that does not affect battery replacement, so it can be determined to replace the battery.

Compared with the previous embodiment, in this embodiment, the fault of the battery is determined by the station control system instead of the battery management unit on the electrical device. Therefore, the station control system does not need to read the fault information obtained by the battery management unit on the electrical device, thus reducing the signaling overhead of the station control system.

That is to say, the station control system is equipped with a wireless communication module, and the human battery management unit on the electrical device is also equipped with a wireless communication module. The station control system and the battery management unit on the electrical device establish wireless connections through their respective wireless communication modules. After a wireless connection is established between the station control system and the electrical device, the station control system can obtain battery status information through the wireless connection.

In other embodiments, the station control system can also obtain the status information of the battery on the electrical device from the cloud server. For example, when an electrical device arrives at a power swap station, the station control system searches for all information related to the electrical device from the cloud server based on the license plate information of the electrical device. For example, the status information of the battery on the powered device. Another example is the Media Access Control (MAC) address of the powered device.

Specifically, when the electric device arrives at the battery swap station, the station control system can scan the license plate information of the electric device through the camera of the battery swap station. And search the cloud server for any information related to the electrical device based on the license plate information. For example, the status information of the battery on the power-consuming device, and the MAC address information of the power-consuming device. If the information of the electrical device is found in the cloud server, the electrical device is allowed to enter the power swap station, that is, the station control system can control the opening of the gate system; if the information of the electrical device is not found in the cloud server, Then the electrical device is not allowed to enter the power swap station, that is, the station control system controls the gate system to continue to close.

Optionally, in the embodiment of the present application, obtaining the status information of the battery on the electric device includes: sending a first command to the electric device, the first command being used to request reading of the fault information of the battery; receiving the status information of the battery from the electric device; Battery fault information sent based on the first command.

Usually battery fault information is passively triggered and reported. That is to say, only by sending a command to read the fault, that is, the first command, to the electrical device, the electrical device will report the battery fault information to the station control system. In other embodiments, the power-consuming device can also actively report battery fault information to the station control system, so that the station control system can understand the battery condition. The embodiments of the present application do not limit this.

It should be noted that after a wireless connection is established between the electrical device and the station control system, various information between the station control system and the electrical device can be interacted through the wireless connection. For example, after a Bluetooth connection is established between the station control system and the electrical device, all kinds of information between the station control system and the electrical device can be interacted through the Bluetooth connection.

Optionally, in this embodiment of the present application, sending the first command to the powered device includes: after receiving parameter information of the battery, sending the first command to the powered device, where the parameter information includes power, voltage, and temperature.

The sending cycle can be 100ms. After receiving the parameter information of the battery, the station control system sends the first command to the electrical device. Optionally, the station control system may send the first command to the electrical device after receiving the parameter information of the battery a predetermined number of times.

Optionally, in the embodiment of the present application, the method further includes: after receiving the power swap preparation completion information sent by the power device based on the power swap command, controlling the power swap device of the power swap station to perform power swap; After the power supply is completed, a power replacement completion command is sent to the power consuming device.

Optionally, in the embodiment of the present application, the method further includes: after the power-consuming device performs a high-voltage operation based on the power exchange completion instruction, disconnecting the wireless connection with the power-consuming device.

In this embodiment, after the power-consuming device performs a high-voltage operation, disconnecting the wireless connection with the power-consuming device can ensure that the power-consuming device completes the power exchange at the power swap station.

Specifically, when the station control system determines that the battery needs to be replaced, it can send a battery replacement instruction to the electrical device. After the power-consuming device receives the power-changing command, the power-consuming device enters the power-changing state. For example, electrical devices can operate at high voltages. That is, disconnect the high-voltage connection between the battery and the electrical device. After the power-consuming device enters the power-swapping state, the power-consuming device can send power-swapping preparation completion information to the station control system. After receiving the power exchange preparation completion information, the station control system can control the power exchange device to perform power exchange. For example, the station control system can remove the battery from the electrical device through an automated mechanical device, and install the battery in the battery compartment in the battery swap station to the electrical device. After the battery replacement device installs the battery on the power consumption device, the power replacement can be considered completed, and the station control system can send a power replacement completion instruction to the power consumption device. After the electrical device receives the power exchange completion instruction sent by the station control system, the electrical device can perform a high-voltage operation, that is, the high-voltage connection between the battery and the electrical device can be closed. In the case of communication and interaction between the electrical device and the station control system through wireless connections, after the electrical device performs a high-voltage operation, the electrical device can feed back the high-voltage status information to the station control system, and then the station control system can Disconnect the wireless connection from the powered device. For example, Bluetooth connectivity.

In short, when the station control system determines to replace the battery based on the battery status information, it can control the electrical device to enter the battery replacement process. Since the station control system has judged in advance that there is no fault in the electrical device that affects the battery replacement, this method is adopted. The power exchange performed in this embodiment does not affect the power exchange efficiency.

As shown above, when multiple batteries are installed on the electric device, a master battery management unit MBMU can be installed on the electric device, and each battery on the electric device has a slave battery management unit SBMU. MBMU and SBMU can communicate with each other. For example, the SBMU can send battery status information to the MBMU. For example, battery parameter information, fault information, battery relay closing status, etc. In this embodiment of the present application, the MBMU and SBMU can communicate through wireless connections. For example, communication can be carried out via a Bluetooth connection.

In this embodiment, wireless connection is used between the MBMU and the SBMU, which will not cause problems with the life of the lead connector or communication problems caused by damage to the wiring harness, thereby improving the battery replacement life cycle.

When performing a power swap, you can first disconnect the wireless connection between the MBMU and the SBMU of the depleted battery on the power-consuming device. When the fully-charged battery in the power-swapping station is installed on the power-consuming device, you can establish the connection between the MBMU and the SBMU. Wireless connection between SMBU with fully charged battery. Afterwards, the MBMU can communicate wirelessly with the SMBU with a fully charged battery.

As shown above, when the battery removed from the electrical device is placed in the charging compartment of the battery swap station for charging, the charging cabinet and the battery can communicate using wireless connections, such as Bluetooth communication, which makes the battery swap easier. Each charging compartment in the cabinet no longer needs a control module, thus saving wiring harnesses and control modules and reducing costs.

Through wireless communication between the SBMU of the battery and the CBMU in the charging cabinet, the battery can be monitored in and out of the warehouse, real-time monitoring of battery status, battery fault detection and charging control. Specifically, when the battery is put into the warehouse, the station control system can send relevant information about the battery to the CBMU, including the location of the warehouse to be placed, the MAC address information of the battery, etc. Optionally, the station control system can send battery-related information to the CBMU through the CAN line, and the station control system can also send battery-related information to the CBMU through a wireless connection. For example, Bluetooth connectivity. CBMU can initiate a Bluetooth connection request to SBMU based on the MAC address information of the battery sent by the station control system. After the battery is successfully placed in the warehouse, CBMU can read the battery status information, including various parameter information such as battery voltage, power, and temperature. Further, the CBMU can read whether the battery has a fault, and if a battery fault is detected, charging of the battery is prohibited. It also prompts the station control system that the battery is faulty, and professional engineers conduct further inspections. If it is detected that the battery is not faulty, the battery is allowed to be charged. When the CBMU recognizes that the battery power is insufficient to set the set value, it can send voltage demand, current demand and charging permission information to the station control system. After receiving the voltage demand, current demand and charging permission information sent by the CBMU, the station control system controls the charging compartment to output the corresponding voltage and current to charge the battery. When the CBMU recognizes that the battery power reaches the set value, the CBMU can update the charging permission flag and notify the station control system to exit charging. After receiving the exit charging information sent by the CBMU, the station control system controls the voltage and current output of the charging compartment and stops charging. When the battery needs to be taken out of the warehouse, the station control system can send an exit instruction to the CBMU. After receiving the exit instruction, the CBMU disconnects the wireless connection with the battery. The station control system can then control the battery to move out of the charging compartment.
