Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of new energy vehicle power control, and in particular relates to a vehicle charger inverter function control system, method, device and medium. Background Art
[0002] In recent years, with the rapid global adoption of new energy electric vehicles, users' demands for more diverse vehicle functionality have become increasingly pronounced. This is especially true in scenarios such as outdoor camping, emergency rescue, or mobile office work, where there's an urgent need to convert the vehicle's high-voltage DC power supply into 220V / 50Hz AC power to power conventional household appliances. However, existing electric vehicles generally lack native, efficient inverter output capabilities, forcing users to rely on external inverters. This makeshift solution has significant drawbacks: First, the external inverter is completely decoupled from the vehicle's battery management system (BMS), lacking real-time access to key parameters such as the battery's state of charge (SOC) and temperature, which can easily lead to battery overdischarge and vehicle power supply failure. Second, traditional solutions rely on manual operation of physical switches to control the inverter's start and stop, making it impossible to achieve dynamic power regulation and difficult to automatically trigger protection mechanisms when the battery reaches critical levels.
[0003] At the same time, the output characteristics of electric vehicle power batteries are highly nonlinear, with their maximum allowable discharge power exponentially decreasing as the SOC decreases. Conventional inverter systems, however, rely solely on fixed power thresholds for protection. When a user connects a high-power device (such as a 2000W electric oven) and the battery is in a low SOC state, the battery terminal voltage will drop sharply to the protection threshold, triggering an unexpected system shutdown. Conversely, conservatively setting a high power limit will fail to fully utilize the battery's output potential at high SOC. Furthermore, existing inverter solutions generally lack a human-machine collaborative control mechanism: users must individually operate the central control panel's function switches, physically plug and unplug the inverter gun, and start and stop the load device. This process is lengthy and prone to false triggering. Summary of the Invention

[0008] Preferably, when the on-board VCU module receives the unmarked real-time on-board BMS module inverter status, inverter power and SOC value, it sends an inverter start request to the on-board central control screen module; When receiving the inverter status, inverter power and SOC value of the on-board BMS module that fails the mark verification, the on-board VCU module generates a shutdown command and transmits it to the on-board BMS module.

Whether the current temperature of the vehicle's BMS module is within the range of 0°C to 45°C; Check whether the maximum output power allowed by the on-board charger module reaches or exceeds 3.3kW.

DETAILED DESCRIPTION
[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.
[0018] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise indicated, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present invention.
[0019] In order to achieve the above object, the technical problem of the present invention is achieved through the following measures: The present application discloses a vehicle charger inverter function control system, comprising: Vehicle inverter gun module, used to provide 220VAC AC output interface and generate gun connection signal; The on-board charger module is used to obtain the plug gun connection signal and transmit the plug gun connection signal to the on-board BMS module; convert the DC power of the power battery into 220VAC AC power output according to the execution instruction, or shut down the current output according to the shutdown instruction; The on-board BMS module is used to verify the real-time on-board BMS module inverter status, inverter power and SOC value after receiving the plug connection signal, and then report it to the on-board VCU module, and receive the execution command or shutdown command of the on-board VCU module and transmit it to the on-board charger module; The on-board VCU module is used to receive the real-time inverter status, inverter power, and SOC value of the on-board BMS module, send an inverter start request to the on-board central control panel module, or generate a shutdown command to transmit to the on-board BMS module; and receive the execution command of the on-board central control panel module and transmit it to the on-board BMS module; The vehicle-mounted central control screen module is used to receive the request to start the inverter and display the relevant user confirmation information, and issue the execution instruction after the information is confirmed.
[0020] The core system addresses the pain point of "accidental power feed" in EV inverter discharge scenarios. By monitoring the SOC value in real time and setting a hard exit threshold (e.g., below 20%), the inverter output is proactively shut down before the battery charge reaches the safety limit, ensuring the vehicle always maintains the minimum required power to operate, preventing users from becoming paralyzed due to power consumption. A complete chain is established: from hardware signal triggering (plugging in the battery), to BMS core status verification (SOC / temperature / power), to VCU decision-making and command distribution, and finally confirmation through human-machine interaction. BMS verification is the cornerstone of safety, ensuring the battery itself is in a healthy, dischargeable state (suitable temperature and power). User confirmation on the central control screen is the boundary of responsibility, preventing misoperation. VCU command dispatch is the control center, ensuring reliable process execution. This layered verification mechanism significantly reduces the risk of single module failure or misjudgment. Furthermore, the onboard charger converts the high-voltage DC power output of the EV's power battery into 220VAC AC power, which is used by household appliances. When the vehicle's power battery is low on power, the vehicle enters low-battery protection mode and automatically exits inverter output mode, ensuring the risk of power feed.
[0021] In some embodiments, a vehicle charger inverter function control system, such as Figure 1 、 Figure 2As shown in the figure, it consists of a vehicle inverter module, a vehicle charger module, a vehicle BMS module, a vehicle VCU module and a vehicle central control screen module.
[0022] The vehicle inverter gun module is mainly used to provide an AC 220VAC output interface and input a gun connection signal to the vehicle charger; The on-board charger module is mainly used to sample the inverter gun plug-in signal and convert the DC power of the electric vehicle power battery into AC power for output; The on-board BMS module is mainly used to provide output energy of the inverter function for the on-board charger module; The vehicle-mounted VCU module is mainly used for enabling / disabling the vehicle-mounted AC inverter function and real-time monitoring of the inverter status; The vehicle-mounted central control screen module is mainly used for human-computer interaction with the user and the transmission of function setting signals.
[0023] In some embodiments, a vehicle charger inverter function control system, such as Figure 1 、 Figure 2 As shown, it includes a vehicle inverter module, a vehicle charger module, a vehicle BMS module, a vehicle VCU module and a vehicle central control screen module. When the vehicle is powered on in the ON gear and the AC inverter function is realized, after the user inserts the vehicle inverter gun, the on-board charger detects the insertion of the inverter gun through the resistance change of the CC signal. At this time, the on-board charger reports the gun insertion signal to the on-board BMS module; when the on-board BMS module detects that it meets the relevant inverter output conditions, it will report the current module's inverter status, inverter power and current SOC power value to the on-board VCU module; when the on-board VCU module receives the relevant information of the on-board BMS module, it will send the relevant inverter start request to the on-board central control screen module; when the on-board central control screen module receives the inverter enable request of the on-board VCU module, it will display the relevant user confirmation information on the central control screen. When the user confirms to enable the inverter function, the related modules will transmit the relevant signals step by step. Finally, the on-board charger module will be able to convert the DC power of the on-board BMS module into 220VAC AC power that can be used for household appliances.
[0024] In some embodiments, the vehicle inverter gun module generates a gun plug connection signal specifically as follows: when the vehicle inverter gun is inserted, a CC signal resistance change is generated, and the CC signal resistance change is transmitted to the vehicle charger module as a gun plug connection signal.
[0025] In some embodiments, after receiving the plug connection signal, the vehicle-mounted BMS module verifies the current vehicle-mounted BMS module inverter state, inverter power, and current SOC value and reports it to the vehicle-mounted VCU module, specifically including: After receiving the plug connection signal, the onboard BMS module verifies whether the battery SOC value, temperature and output power meet the preset conditions; if so, the verification passes; otherwise, the verification fails; When the verification is passed, the on-board BMS module reports the real-time on-board BMS module inverter status, inverter power and SOC power value to the on-board VCU module; When the verification fails, the on-board BMS module reports the real-time on-board BMS module inverter status, inverter power and SOC power value to the on-board VCU module and marks the verification as failed.
[0026] Further preferably, when the on-board VCU module receives the unmarked real-time on-board BMS module inverter state, inverter power and SOC power value, it sends an inverter start request to the on-board central control screen module; When receiving the inverter status, inverter power and SOC value of the on-board BMS module that fails the mark verification, the on-board VCU module generates a shutdown command and transmits it to the on-board BMS module.
[0027] The preset conditions are: Is the SOC value of the vehicle-mounted BMS module greater than 20%? Whether the current temperature of the vehicle's BMS module is within the range of 0°C to 45°C; Check whether the maximum output power allowed by the on-board charger module reaches or exceeds 3.3kW.
[0028] Since the on-board AC inverter function converts the power of the vehicle's power battery into AC power for use, turning this function on will affect the vehicle's range. To avoid excessive use of the vehicle's power and ultimately leading to vehicle power outages, this inverter function will automatically shut down when the vehicle's battery SOC value falls below a certain value. The vehicle's minimum default limit is 20%. Users can also adjust the limit to a value greater than 20 through the large screen to ensure the normal use of other vehicle functions.
[0029] To sum up, the vehicle charger inverter function control system provided by the embodiment of the patent of the present invention can more effectively realize the AC inverter function of electric vehicles, greatly improve the functional diversity of the entire vehicle and meet the user's usage needs, and has extremely high market application prospects and product value.

[0031] In some embodiments, the gun connection signal is a change in CC signal resistance generated when a vehicle inverter gun is inserted.
[0032] In some embodiments, after receiving the plug connection signal, the vehicle-mounted BMS module verifies the real-time vehicle-mounted BMS module inverter state, inverter power, and SOC value and then reports it to the vehicle-mounted VCU module, specifically including: After receiving the plug connection signal, the onboard BMS module verifies whether the battery SOC value, temperature and output power meet the preset conditions; if so, the verification passes; otherwise, the verification fails; When the verification is passed, the on-board BMS module reports the real-time on-board BMS module inverter status, inverter power and SOC power value to the on-board VCU module; When the verification fails, the on-board BMS module reports the real-time on-board BMS module inverter status, inverter power and SOC power value to the on-board VCU module and marks the verification as failed.
