Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electric vehicles, and more specifically, to a charging control method, system, vehicle, and storage medium for an electric vehicle. Background Art

[0002] With the rapid development of the new energy vehicle industry, improving charging and recharging efficiency has become key to enhancing user experience and reducing operating costs. Currently, when a vehicle is undergoing AC / DC charging (AC / DC), not only are the battery management system (BMS) and on-board charger (OBC) awakened, but all high-voltage components, including the core motor control unit (MCU), are also in a high-energy consumption state, even when the vehicle is stationary. This increases energy consumption and reduces charging efficiency. Although related technologies have attempted to optimize the charging process, the MCU remains fully awake during vehicle charging, continuously consuming energy and failing to effectively reduce energy consumption, indirectly leading to increased charging costs and a compromised user experience. During the charging and recharging phase, the vehicle is not moving, but the MCU remains in a high-power consumption state, consuming the energy of the entire vehicle. This not only increases charging time, but also increases the user's charging cost, reducing overall charging efficiency and range.

[0042] In this embodiment, a method for controlling charging of an electric vehicle is provided. Figure 1 is a flow chart of an electric vehicle charging control method according to an embodiment of the present application. Figure 1 As shown, the process includes the following steps:

[0043] Step S11, in response to receiving a charging connection signal from a target vehicle, obtaining charging demand data corresponding to the target vehicle, wherein the charging connection signal is used to determine whether a charging connection has been established between the target vehicle and the vehicle charging pile, and the charging demand data is used to indicate a vehicle battery status corresponding to the target vehicle and a user's charging demand;

[0044] Step S12: generating energy-saving control request information based on the charging demand data, wherein the energy-saving control request information is used to perform an energy-saving control operation on the to-be-controlled object of the target vehicle;

[0045] Step S13, sending energy-saving control request information to the object to be controlled;

[0046] Step S14: receiving energy-saving control response information corresponding to the energy-saving control request information, wherein the energy-saving control response information is used to determine whether the operating state of the object to be controlled is switched from the normal operating mode to the energy-saving operating mode.

[0047] The above-mentioned charging connection signal can be detected and sent by the vehicle charging pile. When a physical connection is established between the target vehicle and the charging pile, the charging pile will generate a charging connection signal, which is captured by the battery management system BMS or the on-board charger OBC, and then wake up the relevant control module to prepare for charging.

[0048] After the target vehicle establishes a charging connection with the charging pile, the BMS will evaluate the vehicle's battery status, including the remaining battery capacity (State of Charge, SOC), battery temperature, battery health, etc. At the same time, it will collect the charging requirements set by the user through the human-machine interface (such as a touch screen or mobile phone application), such as the maximum charging power, charging deadline, etc., and summarize the above data into charging demand data to guide subsequent charging control strategies.

[0049] The energy-saving control request message, also known as the low-power request message, is generated by the vehicle control unit (VCU) based on charging demand data. It contains specific instructions for implementing energy-saving control on specific high-voltage components of the vehicle, such as the motor controller (MCU). The purpose of the energy-saving control request message is to notify the controlled object, the MCU, to enter a low-power mode, shutting down or reducing non-essential power modules to reduce energy consumption during charging.

[0050] The above-mentioned object to be controlled can drive the motor controller MCU, which is a key component of the vehicle's electric drive system and plays an important role in the charging process. By receiving energy-saving control request information, it can perform energy-saving control operations and switch to low-power mode.

[0051] The energy-saving control response message is sent by the controlled object (MCU) after receiving the energy-saving control request message, indicating that it has followed the instruction and successfully switched from normal operation mode to energy-saving operation mode. The energy-saving control response message is crucial for the VCU to monitor energy management and system status throughout the charging process.

[0052] When the charging pile detects that the charging port of the target vehicle has been connected, it will send a charging connection signal. After receiving this signal, the BMS or OBC will wake up and evaluate the status of the vehicle battery. At the same time, it will collect any charging requirements set by the user, such as charging to 80% SOC, and then summarize them into charging demand data to provide a basis for the next energy-saving strategy.

[0053] The vehicle controller (VCU) generates energy-saving control request information based on the collected charging demand data. This energy-saving control request information contains specific instructions that instruct the MCU to enter a low-power mode during charging to reduce unnecessary energy consumption. For example, it shuts down the resolver decoder power supply module, the power driver power supply module, and the current sampling power supply module.

[0054] The VCU sends energy-saving control requests via the vehicle's communication network to the MCU, the target device to be controlled. Upon receiving this information, the MCU performs specific internal operations, such as shutting down non-essential power circuits to reduce power consumption, while ensuring the normal operation of its communication and monitoring functions.

[0055] After executing the energy-saving control operation, the MCU sends an energy-saving control response message to the VCU to confirm that it has successfully switched to energy-saving operation mode. By receiving this response message, the VCU can monitor the status of the MCU in real time to ensure that energy management during the charging process is effectively optimized.

[0056] Through the above process, the embodiment of the present application can dynamically adjust the power consumption of the MCU during the charging and energy replenishment process of the target vehicle, ensuring that it enters a low-power state when no power output is required. This not only significantly reduces the MCU's energy consumption of the entire vehicle during charging, improving the efficiency of charging and energy replenishment, but also reduces the energy consumption of end users during the charging process, indirectly reducing the cost of using the vehicle. Through precise energy management and control, the efficiency of charging and energy replenishment for new energy vehicles is significantly improved, energy utilization is optimized, and the user experience is further enhanced.

[0057] Based on the above steps S11 to S14, by responding to the charging connection signal received from the target vehicle, the charging demand data corresponding to the target vehicle is obtained, and then energy-saving control request information is generated based on the charging demand data, and then the energy-saving control request information is sent to the object to be controlled, and finally the energy-saving control response information corresponding to the energy-saving control request information is received. In this way, by intelligently identifying the charging demand and executing the energy-saving control operation of the object to be controlled, the purpose of efficient charging and energy replenishment, reduced energy consumption, and improved user experience is achieved, thereby achieving the technical effect of improving charging efficiency, reducing charging costs, and extending battery life, and thus solving the technical problems of low charging efficiency and high charging costs in the electric vehicle charging method provided in the relevant technology.

[0058] The following is a further introduction to the electric vehicle charging control method in the embodiment of the present application.

[0059] In an optional embodiment, the electric vehicle charging control method in the embodiment of the present application further includes:

[0060] Determine the charging demand power corresponding to the target vehicle based on the charging demand data;

[0061] The target vehicle is charged and managed according to the charging power requirement.

[0062] This charging demand data combines the vehicle's battery's current state, such as state of charge, battery temperature, and battery health, with the user's charging requirements, such as charging to a specific state of charge (SOC), a charging deadline, or a maximum charging rate. This charging demand data is key information for determining charging strategies and optimizing energy allocation.

[0063] The above charging power requirement is calculated based on the charging demand data and reflects the amount of power required to charge the vehicle battery to a user-specified state (e.g., SOC level). The charging power requirement is determined by considering not only the physical characteristics of the battery but also the user's specific charging requirements, ensuring the desired charging performance while efficiently utilizing power resources.

[0064] Before the target vehicle starts charging and replenishing energy, the VCU first obtains the current battery status and the charging requirements set by the user, and uses the charging demand data to calculate the charging demand power required by the target vehicle, that is, the electric power value that the charging pile should provide in order to achieve the charging target set by the user, thereby ensuring the accurate matching of charging energy and avoiding energy waste.

[0065] After determining the required charging power, the VCU sends this information to the BMS or OBC. The BMS or OBC then adjusts the charging pile's output power based on the required power to precisely match the target vehicle's charging needs. For example, the charging pile's power output is controlled to ensure the target vehicle receives energy most efficiently during the charging process. Furthermore, key components like the MCU are configured to enter low-power mode to further optimize energy consumption during the charging process. Charging management is central to achieving efficient and energy-saving charging. By dynamically adjusting the charging pile's output and MCU power consumption, it ensures optimal resource utilization during the charging process.

[0066] Based on the above optional embodiment, by determining the charging demand power corresponding to the target vehicle based on the charging demand data, and then managing the charging of the target vehicle according to the charging demand power, refined control of the charging process and efficient use of energy are achieved, ensuring that the power output by the charging pile accurately matches the actual needs of the vehicle, thereby reducing energy waste.

[0067] In an optional embodiment, the electric vehicle charging control method in the embodiment of the present application further includes:

[0068] Obtaining the entire vehicle operating status of the target vehicle, wherein the entire vehicle operating status is used to determine whether the target vehicle is in a dormant state;

[0069] In response to the entire vehicle operating state not being in a dormant state, a charging connection signal from a target vehicle is received.

[0070] The vehicle's operating status represents the current operating mode and system activity of the target vehicle, encompassing multiple dimensions such as driving status, electrical system activity levels, and component wake-up status. By monitoring the vehicle's operating status, it is possible to determine whether the target vehicle is in sleep mode, meaning that most of the vehicle's systems and electrical components are deactivated or in a low-power state for energy conservation.

[0071] Sleep mode is a vehicle energy-saving mode in which the power consumption of most high-voltage and low-voltage components, such as the MCU, is minimized to reduce energy waste when the vehicle is stationary or not in use. In sleep mode, the vehicle typically maintains only essential support functions, such as the anti-theft system and remote communications.

[0072] Before charging begins, the system first checks the overall operating status of the target vehicle to determine if it is in a dormant state. This determination is made by reading vehicle status information stored within the VCU or querying the status of key system components via the vehicle communication network. This is crucial for successfully receiving the charging connection signal and preparing for charging.

[0073] If it is detected that the target vehicle has not entered the sleep state, the vehicle's BMS or OBC will continue to be in an active listening state so that it can capture the charging connection signal from the charging pile in time and send the charging connection signal to the VCU, thereby ensuring that when the vehicle is in a non-sleep state, it can quickly respond to charging requests and avoid unnecessary delays and energy consumption.

[0074] Based on the above optional embodiment, by obtaining the whole vehicle operating status of the target vehicle, and then responding to the whole vehicle operating status not being in a dormant state, receiving the charging connection signal of the target vehicle, not only the charging preparation speed is accelerated, but also it is ensured that the vehicle can quickly enter the optimal energy consumption management state when charging, laying the foundation for subsequent low-power mode switching and energy-saving control, and further improving the charging efficiency.

[0075] In an optional embodiment, the electric vehicle charging control method in the embodiment of the present application further includes:

[0076] In response to the entire vehicle operating state being in a dormant state, obtaining a vehicle wake-up signal;

[0077] In response to completing a wake-up operation on the target vehicle based on the vehicle wake-up signal, a charging connection signal from the target vehicle is received.

[0078] When the vehicle is detected to be in sleep mode, it means that the various systems and devices of the vehicle are in an extremely low energy consumption state. In this scenario, the VCU in the embodiment of the present application will closely detect the presence of the vehicle wake-up signal. The vehicle wake-up signal is sent by the BMS or OBC to the VCU, and the vehicle is high-voltage based on the vehicle wake-up signal. When the vehicle is in a high-voltage state, the VCU can receive a charging connection signal from the target vehicle from the BMS or OBC.

[0079] After receiving the vehicle wake-up signal, the target vehicle gradually resumes high-voltage system operation, including waking up key components from a dormant state and activating them in preparation for charging. This wake-up process is orderly and efficient, ensuring that all necessary systems are fully prepared before charging begins.

[0080] Based on the above optional embodiment, by responding to the entire vehicle operating state being in a dormant state, obtaining a vehicle wake-up signal, and then completing a wake-up operation on the target vehicle in response to the vehicle wake-up signal, and receiving the charging connection signal of the target vehicle, not only the speed of charging preparation is accelerated, but also the vehicle can quickly respond to external charging requests, reducing the additional energy consumption caused by system wake-up.

[0081] In an optional embodiment, the charging demand data includes at least one of the following: vehicle battery status, user charging demand, charging pile type information, and charging environment information.

[0082] The vehicle battery status mentioned above refers to the current operating condition and performance indicators of the new energy vehicle battery. It mainly includes the state of charge (SOC), which is the ratio of the remaining battery charge to the fully charged state; battery temperature; battery health, which reflects the degree of battery performance degradation; and other relevant battery parameters such as voltage and internal resistance. The vehicle battery status is crucial for assessing the battery's charging capacity, determining the appropriate charging rate, and preventing overcharging or over-discharging.

[0083] User charging requirements refer to the end user's personalized requirements during the charging process, including but not limited to the desired target SOC level, estimated charging deadline, maximum allowable charging power, or charging priority. The VCU receives this information through the vehicle's human-machine interface to better adapt to user habits and specific scenario requirements, thereby improving the charging experience.

[0084] The charging pile type information mentioned above involves the classification and specifications of the charging pile, such as whether it is an AC charger or a DC charger, maximum output power, and charging protocol standards. This charging pile type information helps the VCU understand available charging resources and ensure that the charging process complies with relevant standards and vehicle compatibility requirements.

[0085] The above charging environment information covers the external conditions of the charging location, including temperature, humidity, grid stability, and the surrounding environment of the charging facility. These factors affect charging efficiency and safety. For example, in extremely low temperature conditions, the battery may need to be preheated to improve charging efficiency.

[0086] The embodiment of the present application stipulates that the charging demand data should include at least one item such as vehicle battery status, user charging demand, charging pile type information and charging environment information. This means that when formulating a charging strategy, various factors affecting the charging process can be fully considered, thereby improving the intelligence and personalization of charging control, ensuring that user needs can be met and existing resources can be fully utilized, while maintaining battery health and extending battery life, thereby improving the efficiency, safety and user experience of the charging process as a whole.

[0087] Figure 2 is a flow chart of another electric vehicle charging control method according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0088] Step S21: receiving energy-saving control request information, wherein the energy-saving control request information is generated based on charging demand data, the charging demand data is obtained in response to receiving a charging connection signal from a target vehicle, the charging demand data is used to indicate a vehicle battery status corresponding to the target vehicle and a user's charging demand, and the charging connection signal is used to determine whether a charging connection has been established between the target vehicle and the vehicle charging station;

[0089] Step S22, performing energy-saving control operations on the object to be controlled of the target vehicle based on the energy-saving control request information, and returning energy-saving control response information, wherein the energy-saving control response information is used to determine whether the operating state of the object to be controlled is switched from the normal operating mode to the energy-saving operating mode.

[0090] Based on the above steps S21 to S22, by receiving energy-saving control request information, and then performing energy-saving control operations on the object to be controlled of the target vehicle based on the energy-saving control request information, and returning energy-saving control response information, the charging demand is intelligently identified and the energy-saving control operation of the object to be controlled is performed, thereby achieving the purpose of efficient charging and energy replenishment, reducing energy consumption, and improving user experience, thereby achieving the technical effect of improving charging efficiency, reducing charging costs, and extending battery life, and thus solving the technical problems of low charging efficiency and high charging costs in the electric vehicle charging method provided in the relevant technology.

[0091] In an optional embodiment, in step S22, performing an energy-saving control operation on the to-be-controlled object of the target vehicle based on the energy-saving control request information includes:

[0092] Based on the energy-saving control request information, the communication function module in the object to be controlled is controlled to maintain a normal operation mode, and the non-communication function module in the object to be controlled is controlled to switch from a normal operation mode to an energy-saving operation mode.

[0093] The aforementioned controlled object can be an MCU. During the charging and recharging process of new energy vehicles, the MCU is a key component responsible for important tasks such as driving the motor, decoding resolver signals, and current sampling. However, these functions are not essential during the charging phase, rather than the driving phase. Therefore, the MCU is considered an object that can implement energy-saving control.

[0094] In this embodiment of the application, the communication function module refers to the part of the MCU responsible for exchanging data with other vehicle controllers (such as VCU, BMS, OBC, etc.) through the vehicle network. The communication function module needs to remain in normal operating mode to ensure smooth communication with other systems and to receive and send necessary control signals and status information in real time even during charging.

[0095] The non-communication function module encompasses all MCU components other than communication functions, including the resolver decoder module, power driver module, current sampling module, and the power supply module for some processor functions. During the charging and recharging phase, these modules are not required and can be switched from normal operation to energy-saving mode, significantly reducing overall power consumption.

[0096] In the embodiment of the present application, even under energy-saving control, it is necessary to ensure that the communication function module maintains a normal operating mode. During the charging and energy replenishment process, the MCU still needs to maintain effective communication with other controllers such as the VCU in order to receive charging instructions, feedback status information and coordinate the entire charging process. This accurately balances the requirements of energy saving and functionality, reducing unnecessary energy consumption while maintaining the stability and controllability of the charging process.

[0097] The embodiment of the present application controls the non-communication function module to switch from the normal operating mode to the energy-saving operating mode to significantly reduce the power consumption of the MCU, including but not limited to shutting down the power supply of the resolver decoding module, the power drive module, the current sampling module and some functions of the processor. In this way, inactive modules during the charging process are specifically paused, energy waste is reduced, and charging efficiency is improved, electricity costs are reduced, and the user charging experience is enhanced.

[0098] Figure 3 FIG. 1 is a schematic diagram of an interactive process of an electric vehicle charging control method according to an embodiment of the present application, such as Figure 3As shown, a DC or AC charging station is connected to a new energy vehicle charging station under external control and exchanges signals with the vehicle's BMS or OBC. The BMS or OBC exchanges low-voltage signals with the charging station, identifies the charging station's plug status, and reports this to the VCU. Upon receiving the plug signal from the BMS or OBC, the VCU simultaneously calculates the vehicle's charging power requirement and sends this feedback to the BMS or OBC. Simultaneously, it sends a low-power mode request to the MCU. Upon receiving the low-power mode request from the VCU, the MCU executes internal actions, shuts down some of its internal power supply circuits, and reports back to the VCU indicating that it is currently in low-power mode.

[0099] Figure 4 is a schematic diagram of an electric vehicle charging control method according to an embodiment of the present application, such as Figure 4 As shown, the BMS or OBC receives the charging connection signal from the vehicle charging pile. If the vehicle is currently in a dormant state, the BMS or OBC sends a vehicle wake-up signal, the vehicle is in a high-voltage state, and the vehicle sends a charging connection signal to the VCU. After receiving the charging connection signal sent by the BMS or OBC, the VCU calculates the current charging power requirement of the vehicle and feeds it back to the BMS or OBC, and simultaneously sends an energy-saving control request message to the MCU. After receiving the energy-saving control request message sent by the VCU, the MCU performs internal actions, including shutting down some power supply circuits inside the drive motor control. The state machine jumps to low-power mode and feeds back energy-saving control response information to the VCU, indicating that it has successfully switched to low-power mode. If the vehicle is already in a high-voltage wake-up state before the gun is plugged in, there is no need for the BMS or OBC to send a vehicle wake-up signal, and the charging connection signal can be sent directly to the VCU.

[0100] Figure 5 is a schematic diagram of a state machine change according to an embodiment of the present application, such as Figure 5As shown, the target vehicle state machine includes a low-voltage standby module, a high-voltage ready module, a low-power consumption mode module, and a torque control module. The low-voltage standby module indicates that the vehicle is in a low-voltage state. The module that drives the motor controller, which consumes energy from the low-voltage battery, can switch between the low-power consumption mode module and the high-voltage ready module based on vehicle instructions. The high-voltage ready module indicates that the vehicle is in a high-voltage state. High voltage is applied to the vehicle, and all high-voltage components are operating normally and consuming energy from the battery. This module switches between the low-voltage standby module, the low-power consumption mode module, and the torque control module based on vehicle instructions. The low-power consumption mode module indicates that the drive motor controller described in this solution is in low-power mode, reducing vehicle energy consumption and improving charging efficiency. The torque control module is responsible for controlling the motor torque, that is, the force and speed output by the motor, to meet the vehicle's driving or power requirements. In driving mode, the MCU uses the torque control module to adjust the motor's output torque to ensure vehicle performance and safety.

[0101] Figure 6 This is an internal hardware architecture diagram of a drive motor controller according to an embodiment of the present application. Figure 6 As shown, the MCU includes: a low-voltage battery for the vehicle, a power management module, a communication module, a processor module, a resolver decoding module, a power drive module, and a current sampling module. In normal high-voltage standby and torque control modes, all modules within the MCU function normally. The power management module manages the MCU's power supply, including sensor power, communication power, and processor power. The communication module facilitates network signal exchange between the MCU and other vehicle controllers. The processor module performs sensor sampling, current calculation, derating protection, and communication processing functions. The resolver decoding module calculates the position and speed of the drive motor. The power drive module controls the three-phase current used by the MCU's operating mode module to control the drive motor's motion. The current sampling module samples the three-phase motor current.

[0102] After receiving the low-power command sent by the VCU, the MCU performs internal actions, including shutting down the resolver decoding power supply module, the power module drive power supply module, the current sampling power supply module, and the power supply module for some functions of the main processor while ensuring normal basic communication functions, and feeds back energy-saving control response information to the VCU, indicating that it has successfully switched to low-power mode.
