[0034] Figure 2 This is a battery charging flowchart illustrating an exemplary embodiment;

[0035] Figure 3 This is a schematic diagram of a battery charging device structure according to an exemplary embodiment. Detailed Implementation

[0036] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0037] With the rapid development of new energy vehicles, the number of electric vehicle charging and battery swapping stations is also increasing. These stations provide charging and rapid battery swapping for electric vehicles. Electric vehicles require continuous power replenishment for operation. Therefore, when the battery is low, it needs to be charged to prevent damage. However, with the increasing number of charging and battery swapping station brands, many vehicle batteries are interchangeable and can be charged and swapped at stations from different manufacturers. For example, if a battery swapped at company A's station is replaced at company B, this battery may not only be usable but may also be permanently lost to company A. This results in asset loss for the charging and battery swapping station operators.

[0038] In view of the above situation, this disclosure provides a battery charging method. Figure 1 This is a flowchart illustrating a battery charging method according to an exemplary embodiment. Figure 1 As shown, this battery charging method is applied to a battery-side charging management system, which includes a controller system (BBOX) and a battery system (BMS), comprising:

[0039] Step 10: Establish a charging connection between the battery system (BMS) and the battery swapping station charger;

[0040] Step 11: The controller system BBOX detects whether the battery system BMS has received the charging message and charging authentication ID sent by the charger; wherein the charging authentication ID is used to identify the brand attribute of the battery swapping station charger;

[0041] Step 12: If it is determined that the battery system BMS has received the charging message and the charging authentication ID, and the brand attribute of the battery swapping station charger is determined to be the target brand based on the charging authentication ID, then the battery swapping station charger is allowed to charge the battery.

[0042] In this exemplary embodiment, both the controller system BBOX and the battery system BMS belong to the battery side. The battery system BMS connects to the battery swapping station charger via a CAN bus. The charging message contains charging information after the charger establishes a charging connection with the battery and begins charging. For example, charging current, voltage, power, etc. The charging authentication ID is used to identify the brand attribute of the battery swapping station charger. For example, the charging authentication ID identifies which company and brand the battery swapping station charger belongs to. When the brand attribute of the battery swapping station charger is determined to be the target brand based on the charging authentication ID, it can be determined that the current battery swapping station charger is a dedicated company or brand battery swapping station charger for charging the battery. At this time, the battery can be authorized to receive the power output of the charger.

[0043] The battery charging method according to embodiments of this disclosure is applied to a charging management system at the battery end. The charging management system includes a controller system BBOX and a battery system BMS, and includes: establishing a charging connection between the battery system BMS and the battery swapping station charger; detecting whether the battery system BMS has received a charging message and a charging authentication ID sent by the charger based on the controller system BBOX; wherein the charging authentication ID is used to identify the brand attribute of the battery swapping station charger; if it is determined that the battery system BMS has received the charging message and the charging authentication ID, and the brand attribute of the battery swapping station charger is determined to be the target brand based on the charging authentication ID, then the battery is charged by the battery swapping station charger. In this application, the controller system BBOX detects whether the battery system BMS receives the charging message and charging authentication ID sent by the charger. The charging authentication ID is used to identify the brand attribute of the battery swapping station charger. If it is determined that the battery system BMS has received the charging message and charging authentication ID, and the brand attribute of the battery swapping station charger is determined to be the target brand based on the charging authentication ID, it means that the battery swapping station charger charging the battery is the battery's dedicated company's battery swapping station charger. At this time, it can be determined that the battery returns to the dedicated company's battery swapping station charger for charging, which can effectively increase the probability of the battery returning to the dedicated company's battery swapping station charger for charging, thereby helping to reduce battery loss.

[0044] In some embodiments, the method includes:

[0045] If, based on the charging authentication ID, it is determined that the brand attribute of the battery swapping station charger is not the target brand, or if it is determined that the battery system BMS has not received the charging authentication ID sent by the charger, then the battery swapping station charger is refused to charge the battery.

[0046] In this exemplary embodiment, if the brand attribute of the battery swapping station charger is determined not to be the target brand based on the charging authentication ID, then the charging station charger is refused to charge the battery. That is, the battery is not authorized to receive power output from the battery swapping station charger, thus preventing the charger from charging the battery and forcing the battery to return to a dedicated enterprise or brand-specific battery swapping station charger for charging, thereby reducing battery loss. Alternatively, if it is determined that the battery system BMS has not received the charging authentication ID sent by the charger, indicating that the battery swapping station charger is not a dedicated enterprise or brand-specific charger, then the charging station charger is refused to charge the battery.

[0047] In some embodiments, refusing the battery swapping station charger from charging the battery includes:

[0049] In this exemplary embodiment, when it is determined that the brand attribute of the battery swapping station charger is not the target brand, and the battery swapping station charger is not a dedicated enterprise or dedicated brand battery swapping station charger, a charging fault message can be sent to the charging connection between the battery system BMS and the battery swapping station charger to interfere with the charging of the battery by the battery swapping station charger. This prevents the battery swapping station charger from charging the battery, thereby forcing the battery to return to the dedicated enterprise or dedicated brand battery swapping station charger for charging, which helps to reduce battery loss.

[0050] In some embodiments, the step of detecting whether the battery system (BMS) receives the charging message and charging authentication ID sent by the charger based on the controller system BBOX includes:

[0051] The controller system BBOX detects whether the battery system BMS receives a charging message sent by the charger.

[0052] If it is determined that the battery system BMS has received a charging message sent by the charger, then the controller system BBOX will detect in real time whether the battery system BMS periodically receives the charging authentication ID sent by the charger.

[0053] In this exemplary embodiment, if the battery system BMS does not receive a charging message from the charger, it indicates that the battery swapping station charger is not charging the battery at this time. If the battery system BMS receives a charging message from the charger, it indicates that the battery swapping station charger is charging the battery or is about to charge the battery. In this case, it is necessary to periodically detect whether the battery system BMS receives the charging authentication ID sent by the charger in real time, in order to further determine whether the brand attribute of the battery swapping station charger is the target brand.

[0054] In some embodiments, determining that the brand attribute of the battery swapping station charger is not the target brand includes:

[0055] If it is determined that the charging authentication ID received by the battery system BMS from the charger is not sent periodically, or the sending period of the charging authentication ID by the charger is not a predetermined period, then it is determined that the brand attribute of the charger of the battery swapping station is not the target brand.

[0056] In this exemplary embodiment, if it is determined that the charging authentication ID received by the battery system BMS from the charger is not sent periodically, or the sending period of the charging authentication ID sent by the charger is not a predetermined period, it indicates that the battery swapping station charger may be a counterfeit brand. In this case, a charging fault message can be sent to the charging connection between the battery system BMS and the battery swapping station charger based on the controller system BBOX to interfere with the charging of the battery by the battery swapping station charger.

[0057] Figure 2 This is a battery charging flowchart illustrating an exemplary embodiment. Figure 2 As shown, the battery charging process includes:

[0058] Step 20: Establish a charging connection between the charger and the battery system BMS based on the charging CAN bus;

[0059] Step 21: The controller system BBOX checks whether there is a charging message in the battery system BMS. If there is no message, the BBOX does nothing.

[0060] Step 22: If a charging message exists in the battery system BMS, determine whether a unique authentication ID (i.e., charging authentication ID) exists in the battery system BMS. If it exists, the BBOX will not take any action. If the unique authentication ID does not exist, a periodic interference message will be sent to the charging connection between the charger and the battery system BMS.

[0061] This disclosure provides a battery-side charging management system, including:

[0062] The battery management system (BMS) is used to establish a charging connection with the battery swapping station charger based on the CAN bus.

[0064] If the battery system BMS determines that it has received the charging message and the charging authentication ID, and determines that the brand attribute of the battery swapping station charger is the target brand based on the charging authentication ID, then the battery swapping station charger will be used to charge the battery.

[0065] In this exemplary embodiment, both the controller system BBOX and the battery system BMS belong to the battery side. The battery system BMS connects to the battery swapping station charger via a CAN bus.

For example, charging current, voltage, power, etc. The charging authentication ID is used to identify the brand attribute of the battery swapping station charger. For example, the charging authentication ID identifies which company and brand the battery swapping station charger belongs to. When the brand attribute of the battery swapping station charger is determined to be the target brand based on the charging authentication ID, it can be determined that the current battery swapping station charger is a dedicated company or brand battery swapping station charger for charging the battery. At this time, the battery can be authorized to receive the power output of the charger.

[0066] The charging management system according to an embodiment of this disclosure includes a controller system BBOX and a battery system BMS; the controller system BBOX is connected to the battery system BMS and is used to detect whether the battery system BMS receives a charging message and a charging authentication ID sent by the charger; wherein the charging authentication ID is used to identify the brand attribute of the battery swapping station charger; and if it is determined that the battery system BMS has received the charging message and the charging authentication ID, and determines that the brand attribute of the battery swapping station charger is the target brand based on the charging authentication ID, then the system receives the battery swapping station charger to charge the battery. In this application, the controller system BBOX detects whether the battery system BMS receives the charging message and charging authentication ID sent by the charger. The charging authentication ID is used to identify the brand attribute of the battery swapping station charger. If it is determined that the battery system BMS has received the charging message and charging authentication ID, and the brand attribute of the battery swapping station charger is determined to be the target brand based on the charging authentication ID, it means that the battery swapping station charger charging the battery is the battery's dedicated company's battery swapping station charger. At this time, it can be determined that the battery returns to the dedicated company's battery swapping station charger for charging, which can effectively increase the probability of the battery returning to the dedicated company's battery swapping station charger for charging, thereby helping to reduce battery loss.

[0069] In this exemplary embodiment, if the brand attribute of the battery swapping station charger is determined not to be the target brand based on the charging authentication ID, then the charging station charger is refused to charge the battery. That is, the battery is not authorized to receive power output from the battery swapping station charger, thus preventing the charger from charging the battery and forcing the battery to return to a dedicated enterprise or brand-specific battery swapping station charger for charging, thereby reducing battery loss. Alternatively, if it is determined that the battery system BMS has not received the charging authentication ID sent by the charger, indicating that the battery swapping station charger is not a dedicated enterprise or brand-specific charger, then the charging station charger is refused to charge the battery.

That is, the battery is not authorized to receive power output from the battery swapping station charger, thus preventing the charger from charging the battery and forcing the battery to return to a dedicated enterprise or brand-specific battery swapping station charger for charging, thereby reducing battery loss.
