[0050] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0051] Please refer to FIG. 1 , which is a flow chart of a charging method in an embodiment of the present application, which is applied to a remote communication terminal (TBOX, an automotive electronic module integrating intelligent information processing and communication technology, whose main function is to realize wireless communication between the vehicle and the outside world, and provide various conveniences and safety guarantees for the driver and the vehicle; the remote communication terminal is located in the vehicle), and the method includes the following steps:

[0052] S101. When the vehicle is in a vehicle power-off position, monitor the voltage of the battery.

[0053] The vehicle may specifically be a new energy vehicle, such as a new energy heavy truck.

[0054] In this embodiment, the TBOX can detect the battery voltage when the vehicle is in the OFF gear (the gear where the whole vehicle is powered off). That is, the vehicle-mounted TBOX will detect the battery voltage of the battery when the power is off.

[0055] Specifically, when performing voltage detection, in order to save power, periodic detection may be performed at regular intervals.

[0056] S102: When it is detected that the battery voltage is lower than a threshold, the internal power resources of the vehicle are used to charge the battery.

[0057] In the embodiment of the present application, a threshold value may be set for the battery. When the battery voltage is lower than the threshold value, it indicates that the battery needs to be charged.

[0058] The specific value of the threshold value may be the normal voltage of the battery, the minimum voltage of the battery to support vehicle starting, or other values, which will not be described in detail here.

[0059] When the battery voltage is detected to be lower than the threshold, the battery can be charged. It should be noted that in this embodiment, when the vehicle is in the OFF gear, the battery is charged using the vehicle's internal power resources. In other words, the battery can be charged without a charging pile or a charging device, which can also be called charging the battery.

[0060] In a specific implementation of the present application, charging the battery includes:

[0061] Wake up the body controller and send a charging request to the body controller;

[0062] After the body controller is successfully awakened, the battery is charged by the body controller.

[0063] For ease of description, the above steps are combined for explanation below.

[0064] Among them, the body controller (BCM) is an electronic control unit that controls the body's electrical system. Common functions include controlling electric windows, electric rearview mirrors, air conditioning, headlights, turn signals, anti-theft locking system, central locking, defrost device, etc.

[0065] TBOX can wake up BCM and then send a charge request to BCM. After BCM is successfully woken up, the body controller can be used to charge the battery.

[0066] In a specific implementation of the present application, waking up the vehicle body controller includes:

[0067] The vehicle body controller is woken up by sending a network management message.

[0068] The specific content of the network management message can be determined by referring to the message protocol and the wake-up setting, which will not be described in detail here. While waking up the body controller, a charging request can also be sent to the body controller. After the body controller is woken up, the charging request can be stopped.

[0069] In a specific implementation of the present application, after the vehicle body controller is successfully awakened, the battery is charged using the vehicle body controller, including:

[0070] After the body controller is awakened, the battery voltage is monitored;

[0071] When the battery voltage is detected to be lower than the threshold, the body controller is used to obtain the status information of the vehicle controller and the battery management system;

[0072] using the status information to determine a current state of the vehicle;

[0073] When the current state is not in the charging state or the maintenance state, the body controller is used to send a charging instruction to the vehicle controller;

[0074] The battery is charged by using the vehicle controller in conjunction with the battery management system, power battery system and converter.

[0075] For ease of description, the above steps are combined for explanation below.

[0076] Vehicle Controller (VCU): The central control unit of a new energy vehicle is the core of the entire control system. Its main functions include driving control, accessory management, energy management, fault handling, information interaction, charge and discharge management, and some thermal management functions.

[0077] Battery Management System (BMS): Main functions include battery status monitoring, battery status estimation, battery protection, energy management, thermal management, balancing control, fault diagnosis and remote monitoring, and analysis of each function.

[0078] That is to say, in this embodiment, when the vehicle is in the OFF gear, the remote communication terminal TBOX controller will regularly detect the battery voltage value. When it is detected that the voltage value is at a low value for a period of time, the TBOX controller will send a network management message to wake up the body controller BCN and send an intelligent power replenishment request to the body controller BCM. When the body controller BCM is successfully awakened, it will stop sending intelligent power replenishment requests.

[0079] The body controller BCM is the intelligent control unit of the low-voltage battery intelligent charging system; after the body controller BCM is awakened, it will monitor the status of controllers such as the vehicle controller VCU and the battery management system BMS, and control whether the vehicle controller continues to charge the vehicle based on the status of each controller and the battery voltage value.

[0080] The monitoring vehicle controller VCU is the charging execution unit of the low-voltage battery intelligent charging system; when the vehicle controller VCU receives the charging instruction from the body controller BCM, it charges the battery in coordination with the battery management system BMS, power battery system, DCDC converter system, etc. For example, the SOC power in the large battery can be charged into the battery.

[0081] S103: During the charging process, monitor the voltage of the battery.

[0082] In this embodiment, considering that the battery is charged without access to external power resources, it is necessary to detect the voltage of the battery during the charging process to avoid wasting power inside the vehicle.

[0083] S104: After monitoring that the battery voltage has reached a normal value, stop charging.

[0084] The normal value may specifically be the rated voltage of the battery, or may be the voltage of the battery that can be used to start the vehicle.

[0085] In order to avoid charging the storage battery, which may cause the power of other batteries to be too low and affect other functions, in the present embodiment, charging can be stopped after the voltage of the storage battery is detected to reach a normal value. Of course, charging of the storage battery can also be stopped after detecting that the power of the large battery is lower than a preset value.

[0086] Specifically, after the battery voltage is detected to reach a normal value, charging is stopped, including:

[0087] After the battery voltage of the battery reaches the normal value, the charging instruction is stopped.

[0088] In a specific implementation of the present application, it further includes: after detecting that a charging gun of the vehicle is inserted, stopping sending a charging instruction. That is, when the charging gun is detected to be inserted, the battery can be stopped from being charged.

[0089] For example: BCM reads the battery voltage message sent by VCU, and stops sending charging instructions when the voltage reaches normal, or stops sending charging instructions when the battery power of SOC is lower than 20%, or stops sending charging instructions after charging for 2 hours.

[0090] In a specific implementation of the present application, after charging is stopped, the method includes: controlling the vehicle body controller to enter a dormant state, so that the vehicle can continue to maintain low power consumption.

[0091] The remote communication terminal applies the method provided in the embodiment of the present application, including: monitoring the voltage of the battery when the vehicle is in a full power-off position; charging the battery using the vehicle's internal power resources when it is detected that the battery voltage is lower than a threshold; monitoring the battery voltage during the charging process; and stopping charging after it is detected that the battery voltage reaches a normal value.

[0092] In order to avoid long-term parking, which may cause low battery voltage and power loss, and eventually lead to the inability to start the vehicle. In this application, it is necessary to monitor the battery voltage when the vehicle is in the power-off position. When the battery voltage is detected to be lower than the threshold, considering that there are not only batteries in the vehicle, but also other electrical resources, such as large batteries, etc., the battery can be charged using the vehicle's internal power resources. During the charging process, the battery voltage is continuously detected, and charging is stopped after the battery voltage reaches the normal value. In this way, the battery voltage can be kept within the normal range, thereby avoiding the automatic charging of the battery through the vehicle's own power resources without the need to connect to the charging pile, thereby keeping the battery voltage stable and ensuring that the vehicle can start normally.

[0093] The technical effect of the present application is that the battery is automatically charged by the vehicle's own power resources without the need for external power intervention, thereby maintaining a stable battery voltage and ensuring that the vehicle can start normally.

[0094] Corresponding to the above method embodiment, the embodiment of the present application further provides a remote communication terminal. The remote communication terminal described below and the charging method described above can refer to each other.

[0098] The voltage monitoring module 103 is also used to monitor the voltage of the battery during the charging process;

[0099] The charging stop module 104 is used to stop charging after monitoring that the battery voltage reaches a normal value.

[0100] By using the remote communication terminal provided in the embodiment of the present application, when the vehicle is in the power-off position, the battery voltage is monitored; when it is monitored that the battery voltage is lower than a threshold value, the battery is charged using the vehicle's internal power resources; during the charging process, the battery voltage is monitored; and charging is stopped after it is monitored that the battery voltage reaches a normal value.

[0113] In a specific implementation of the present application, the sleep control module is used to control the vehicle body controller to enter a sleep state after charging is stopped.

[0114] Corresponding to the above method embodiment, the embodiment of the present application further provides a charging system, and the charging system described below and the charging method described above can be referred to in correspondence with each other.

[0115] Please refer to Figure 3, the charging system includes:

[0116] A vehicle body controller 10, a vehicle controller 20, a battery 30, a battery management system 40 and a remote communication terminal 50;

[0117] A remote communication terminal, used to execute the steps of the charging method as described above;

[0118] The body controller is used to obtain the status information of the vehicle controller and the battery management system after being awakened; when the current state of the vehicle is not in the charging state or the maintenance state, send a charging instruction to the vehicle controller;

[0119] The vehicle controller is used to charge the battery in conjunction with the battery management system when a charging instruction is received.

[0120] Corresponding to the above system embodiment, the embodiment of the present application further provides a vehicle, and the vehicle described below and the charging system described above can refer to each other.

[0121] The vehicle comprises: a charging system as described in the above embodiment.

[0122] In this vehicle, the remote communication terminal (TBOX) is the sleep awakening unit of the low-voltage battery intelligent charging system (i.e., charging system); when the vehicle is in the OFF gear, the remote communication terminal TBOX controller will regularly detect the battery voltage value. When it is detected that the voltage value is at a low value for a period of time, the TBOX controller will send a network management message to wake up the body controller BCN and send an intelligent charging request to the body controller BCM. When the body controller BCM is successfully awakened, it will stop sending intelligent charging requests.

[0123] The body controller BCM is the intelligent control unit of the low-voltage battery intelligent charging system; after the body controller BCM is awakened, it will monitor the status of controllers such as the vehicle controller VCU and the battery management system BMS, and control whether the vehicle controller continues to charge the vehicle based on the status of each controller and the battery voltage value. When the battery voltage reaches the normal value, it will stop sending charging instructions.

[0124] The monitoring vehicle controller VCU is the charging execution unit of the low-voltage battery intelligent charging system; when the vehicle controller VCU receives the charging instruction from the body controller BCM, it cooperates with the battery management system BMS, power battery system, DCDC converter system, etc. to charge the battery.

[0125] In other words, this charging system solves the problem of pure electric vehicles being unable to start when the battery voltage is low or the power is low.

[0126] The steps of the charging method provided in the embodiment of the present application are executed in the remote communication terminal in the system, and the specific implementation process is as follows:

[0127] When the vehicle is in the OFF gear, the remote communication terminal TBOX controller will detect the battery voltage every once in a while. When it detects that the voltage value is at a low value for a period of time, the TBOX controller will send a network management message to wake up the body controller BCM and send an intelligent power replenishment request to the body controller BCM.

[0128] When the body controller BCM is successfully awakened, it will stop sending intelligent charging requests. After the body controller BCM is awakened, it will determine whether to continue charging the vehicle based on the battery voltage value and the status of the vehicle controller VCU, battery management system BMS and other controllers.

[0129] When the body controller detects that the vehicle is not in the charging state and the vehicle is not in the maintenance state, it will send a charging instruction to the vehicle controller VCU. The vehicle controller cooperates with the battery management system BMS, power battery system, DCDC converter and other systems to charge the battery; when it detects that the battery voltage value is normal or the vehicle's charging gun is inserted, it stops sending charging instructions, and the body controller BCM, vehicle controller VCU and other controllers re-enter the sleep state.

[0130] When the vehicle's battery voltage is low or power is low, the vehicle's intelligent charging system can automatically charge and replenish power without human operation. This avoids the risk of the vehicle being unable to start or affecting its normal operation due to low battery voltage or power loss, and effectively improves the user's driving experience.
