It should be noted that, the intelligent power supply method for the low-voltage storage battery of the vehicle in this embodiment may be implemented in cooperation with the intelligent power supply system shown in fig. 2. As shown in fig. 2, the power supply system for implementing the intelligent power supply method for the low-voltage storage battery of the vehicle in the embodiment includes a vehicle terminal, a vehicle supervision platform, a vehicle controller and a high-voltage system.
Specifically, the vehicle-mounted terminal is used for acquiring vehicle state information, wherein the vehicle state information comprises a low-voltage storage battery voltage signal, the vehicle-mounted terminal determines whether the low-voltage storage battery of the vehicle is deficient or not according to the acquired measurement state information, and whether the vehicle meets the power supply condition of the low-voltage storage battery or not, and when the low-voltage storage battery is deficient and the vehicle meets the power supply condition, the acquired vehicle state information is sent to the vehicle supervision platform. The measurement and supervision platform is used for determining the in-out state of the vehicle, judging the in-out state of the vehicle when receiving the low-voltage storage battery power shortage signal sent by the vehicle-mounted terminal, and controlling the high-voltage system of the vehicle to directly supplement power to the low-voltage storage battery or sending power supplement request information to the mobile terminal of the client.
As a preferred embodiment, the method further comprises: setting a compensation control switch on the vehicle, wherein the high-voltage system of the vehicle is normally enabled when the compensation control switch is closed, and the high-voltage system is controlled to keep a power-down state when the compensation control switch is disconnected; when the low-voltage storage battery is deficient, the vehicle meets the electricity supplementing condition and the electricity supplementing control switch is closed, controlling a high-voltage system of the vehicle to directly supplement electricity for the low-voltage storage battery according to the in-out state of the vehicle, or sending electricity supplementing request information to a preset mobile terminal.
The signal of the compensation control switch is connected to the whole vehicle controller, the compensation control switch is cut off, and the whole vehicle controller does not receive a remote compensation request any more, so that the high-voltage system is in a cut-off state to keep a power-down state. The compensation control switch is closed, and the high-voltage system of the vehicle normally works according to the instruction of the whole vehicle controller. Therefore, the vehicle supervision platform is used for judging by combining the vehicle in-out state when the low-voltage storage battery is deficient and the vehicle meets the electricity supplementing condition and the electricity supplementing control switch is closed, and controlling the high-voltage system of the vehicle to directly supplement electricity for the low-voltage storage battery or sending electricity supplementing request information to the mobile terminal of the client. And the high-voltage system receives the command of the whole vehicle controller to power up and power down and supplements power for the low-voltage storage battery.
It is worth to say that, the vehicle state information includes low voltage battery voltage information, high voltage system state information, power battery electric quantity information, vehicle ignition lock state information, vehicle speed information, hand brake state information and gear state information, and whether the low voltage battery of the vehicle is deficient according to the vehicle state information and whether the vehicle meets the power supply condition, includes: if the voltage of the low-voltage storage battery is lower than a preset voltage threshold value, determining that the low-voltage storage battery is deficient; if the high-voltage system of the vehicle has no fault, the electric quantity of the power battery is larger than a preset electric quantity threshold value, the ignition LOCK is in a locking LOCK state, the vehicle speed is smaller than a preset vehicle speed threshold value, the hand brake is in a pulled-up state and the gear is in a neutral gear, determining that the vehicle meets the electricity supplementing condition, otherwise, determining that the vehicle does not meet the electricity supplementing condition.
For example, the vehicle-mounted terminal wakes up at regular time and acquires vehicle state information, including vehicle fault information, vehicle state (ignition lock state, vehicle speed, hand brake, gear, etc.), high-voltage power battery SOC, low-voltage battery voltage, power compensation control switch state, etc. When the voltage of the low-voltage storage battery is lower than a preset voltage threshold, the SOC of the power battery is higher than 20%, a vehicle high-voltage system is in a power-off static state, the vehicle-mounted terminal reports the vehicle power shortage information to a vehicle supervision platform when the power-on control switch is in a closed state, the vehicle supervision platform judges the vehicle in-out state in combination with the vehicle, if the vehicle does not go out of the warehouse, the platform does not need to push the power shortage information to the mobile terminal, the vehicle supervision platform sends the vehicle information which does not go out of the warehouse to the vehicle-mounted terminal, and the vehicle-mounted terminal directly wakes up a vehicle controller to control the high voltage on the high-voltage system to automatically supplement power for the low-voltage storage battery; if the vehicle is already out of the warehouse, the vehicle supervision platform pushes the power supply request information to the mobile terminal, and informs the user that the power supply is required to be authorized.
It can be understood that when the voltage of the low-voltage storage battery is lower than a preset voltage threshold, the SOC of the power battery is greater than 20%, the high-voltage system of the vehicle is fault-free, the vehicle is in a power-off static state, any one of the several conditions that the power-supplementing control switch is in a closed state is not met, and the vehicle-mounted terminal can not report the vehicle power-shortage information to the vehicle supervision platform.
It is worth to say that when a vehicle enters a garage or a parking lot, a guard device shoots and identifies the vehicle, and the vehicle supervision platform can determine the in-out state of the vehicle through interaction with the guard device.
Further, when the low-voltage storage battery is deficient, the vehicle meets the electricity supplementing condition, and the electricity supplementing control switch is closed, controlling the high-voltage system of the vehicle to directly supplement electricity for the low-voltage storage battery according to the in-out state of the vehicle, or sending electricity supplementing request information to a preset mobile terminal, the method comprises the following steps: if the vehicle is in a garage state, controlling a high-voltage system of the vehicle to directly supplement electricity for the low-voltage storage battery; and if the vehicle is in the state of exiting the vehicle warehouse, sending the power supply request information to the mobile terminal.
If the vehicle does not leave the garage, the vehicle-mounted terminal directly controls the whole vehicle controller to wake up the high-voltage system to power up and automatically supplement power for the low-voltage storage battery without pushing the power-up request information to the mobile terminal; if the vehicle is already out of the warehouse, the power-on request information needs to be pushed to the mobile terminal, and a user decides whether to automatically supplement power or not. It will be appreciated that when the vehicle is in a warehouse condition, indicating that the vehicle is not currently being serviced or otherwise in use, the high voltage system can directly recharge the low voltage battery to improve the recharging efficiency of the vehicle. When the vehicle is in a state of exiting the garage, a user participates in deciding whether to supplement electricity or not, so that potential safety hazards caused by the supplement of the low-voltage storage battery of the vehicle are reduced.
Further, after sending the power-up request information to the mobile terminal, the method further includes: and if the mobile terminal returns the power supply authorization information, enabling the high-voltage system to supply power to the low-voltage storage battery.
Enabling the high voltage system to supplement power to the low voltage battery, further comprising: acquiring the power supply state information of the low-voltage storage battery, and sending the power supply state information to the mobile terminal; or if the power supply stopping information sent by the mobile terminal is received, enabling the high-voltage system to stop supplying power to the low-voltage storage battery.
The vehicle control unit receives the authorization information and then sends a power-on instruction to the high-voltage system, so that the high-voltage system supplements power for the low-voltage storage battery. In the electricity supplementing process, the whole vehicle controller feeds back the electricity supplementing state information of the low-voltage storage battery to the vehicle-mounted terminal, the vehicle-mounted terminal feeds back the electricity supplementing state information to the vehicle supervision platform, the vehicle supervision platform is pushed to the mobile terminal, and a user can check the low-voltage electricity supplementing information of the vehicle through the mobile terminal.
In the power supplementing process, the user can also stop supplementing power through the operation of the mobile terminal. When the user sends the authorized power-on stopping information through the mobile terminal, the vehicle supervision platform receives the authorized power-on stopping information from the mobile terminal and transmits the information to the vehicle-mounted terminal, and the vehicle-mounted terminal transmits the power-on stopping information to the vehicle controller. After receiving the power-off supplement instruction, the whole vehicle controller sends a power-off instruction to the high-voltage system, so that the power-off supplement of the low-voltage storage battery is stopped. After the electricity is stopped, the whole vehicle controller feeds the electricity stopping and replenishing information back to the vehicle-mounted terminal, the vehicle-mounted terminal feeds the electricity stopping and replenishing information back to the vehicle supervision platform, the vehicle supervision platform pushes the electricity stopping and replenishing information to the mobile terminal, and a user can check the electricity stopping and replenishing information of the vehicle through the mobile terminal.
Preferably, after the high voltage system is enabled to supplement power for the low voltage storage battery, the method further comprises: acquiring the electricity supplementing time length of the low-voltage storage battery for supplementing electricity at the time; and when the electricity supplementing time length reaches a preset time length threshold value, enabling the high-voltage system to be powered down so as to stop supplementing electricity for the low-voltage storage battery.
It is worth to say that, the in-vehicle terminal is preset to have the timing procedure of charging, namely the voltage of low voltage battery and automatic mapping relation of the time of mending, when confirming according to the voltage and reaching the time threshold value of mending, vehicle terminal sends the instruction of mending electricity to whole car controller, and whole car controller receives the instruction to send down the electric instruction to high voltage system, thereby stop mending the electricity to low voltage battery. After the electricity is supplemented, the whole vehicle controller feeds back electricity supplementing ending information to the vehicle-mounted terminal, the vehicle-mounted terminal feeds back the electricity supplementing ending information to the vehicle supervision platform, the vehicle supervision platform is pushed to the mobile terminal, and a user can check the low-voltage electricity supplementing ending information of the vehicle through the mobile terminal.
Further, after enabling the high voltage system to supplement power to the low voltage storage battery, the method further comprises: and if the power-up control switch off signal is received, enabling the high-voltage system to be powered down so as to stop supplementing the power for the low-voltage storage battery.
For example, in the automatic power-up process, if the vehicle needs to be maintained, even if the maintenance does not involve a high-voltage system, the maintenance personnel still have electric shock risks, and from the aspect of functional safety, the vehicle end must have a way of immediately cutting off the high voltage, and the power-up control switch has the function. Before maintenance, particularly in the case of a vehicle which is already out of stock, the situation that the automatic power supply is not timely when the mobile terminal pushes the vehicle owner to close the automatic power supply can be avoided, and when the vehicle is in the off state, a maintainer can cut off the power supply control switch, the power supply control switch signal is directly connected into the whole vehicle controller, and after the whole vehicle controller receives the power supply control switch signal, a quick power-off instruction is sent to the high-voltage system. When the power-down of the high-voltage system is completed, the whole vehicle controller feeds back the power-off stopping information to the vehicle-mounted terminal, the vehicle-mounted terminal feeds back the power-off stopping information to the vehicle supervision platform, the vehicle supervision platform is pushed to the mobile terminal, a user can check the power-off stopping information of the vehicle through the mobile terminal, and maintenance personnel can perform next maintenance work.
When the low-voltage storage battery of the vehicle is close to full power, the vehicle is not expected to activate automatic power supply, and the charging timing program preset by the vehicle-mounted terminal is short in charging timing close to full power, but the vehicle end is also provided with a path for immediately cutting off high voltage from the aspect of functional safety. When the automatic power supply is not expected to be activated, the vehicle owner can cut off the power supply control switch, and after the whole vehicle controller receives the power supply control switch, a quick power-down instruction is sent to the high-voltage system. When the power-down of the high-voltage system is completed, the whole vehicle controller feeds back the power-off stopping information to the vehicle-mounted terminal, the vehicle-mounted terminal feeds back the power-off stopping information to the vehicle supervision platform, the vehicle supervision platform is pushed to the mobile terminal, a user can check the power-off stopping information of the vehicle through the mobile terminal, and maintenance personnel can perform next maintenance work.
The embodiment of the application provides an intelligent power supplementing method for a low-voltage storage battery of a vehicle. The automatic power supplementing control switch is additionally arranged at the vehicle end, so that the automatic power supplementing function can be directly controlled to be started and closed, and the high voltage of the whole vehicle can be rapidly cut off. The maintenance scene and the unexpected activation automatic electric field supplementing scene are guaranteed, and a user or peripheral personnel can cut off the high voltage of the whole vehicle rapidly, so that personal safety is guaranteed. In a second aspect, an implementation scenario of automatic power up is distinguished. Judging the in-out state of the vehicle through the vehicle supervision platform, and if the vehicle which is not in stock is in a power shortage condition, directly waking up a vehicle end controller through the vehicle-mounted terminal to automatically supplement power; and if the power shortage condition of the vehicle which is already out of the warehouse occurs, pushing the mobile terminal through the platform, and enabling the user to participate in deciding whether to supplement power. The user participates in deciding whether to supplement electricity or not, so that potential safety hazards caused by the electricity supplement of the low-voltage storage battery of the vehicle are reduced.

When the user sends the authorized power-on stopping information through the mobile terminal, the vehicle supervision platform receives the authorized power-on stopping information from the mobile terminal and transmits the information to the vehicle-mounted terminal, and the vehicle-mounted terminal transmits the power-on stopping information to the vehicle controller. After receiving the power-off supplement instruction, the whole vehicle controller sends a power-off instruction to the high-voltage system, so that the power-off supplement of the low-voltage storage battery is stopped. After the electricity is stopped, the whole vehicle controller feeds the electricity stopping and replenishing information back to the vehicle-mounted terminal, the vehicle-mounted terminal feeds the electricity stopping and replenishing information back to the vehicle supervision platform, the vehicle supervision platform pushes the electricity stopping and replenishing information to the mobile terminal, and a user can check the electricity stopping and replenishing information of the vehicle through the mobile terminal.
Preferably, a charging timing program, namely a mapping relation between the voltage of the low-voltage storage battery and automatic power-on time, is preset in the vehicle-mounted terminal, and when the voltage is determined to reach a power-on time threshold value, the vehicle-mounted terminal sends a power-on ending instruction to the vehicle controller, the vehicle controller receives the instruction and sends a power-off instruction to the high-voltage system, so that the power-on of the low-voltage storage battery is stopped. After the electricity is supplemented, the whole vehicle controller feeds back electricity supplementing ending information to the vehicle-mounted terminal, the vehicle-mounted terminal feeds back the electricity supplementing ending information to the vehicle supervision platform, the vehicle supervision platform is pushed to the mobile terminal, and a user can check the low-voltage electricity supplementing ending information of the vehicle through the mobile terminal.
It should be noted that, in the automatic power supply process, if the vehicle needs to be maintained, even if the maintenance does not involve a high-voltage system, the maintenance personnel still has an electric shock risk, and from the aspect of functional safety, the vehicle end must have a way to cut off the high voltage immediately, and the power supply control switch has the function exactly. Before maintenance, particularly in the case of a vehicle which is already out of stock, the situation that the automatic power supply is not timely when the mobile terminal pushes the vehicle owner to close the automatic power supply can be avoided, and when the vehicle is in the off state, a maintainer can cut off the power supply control switch, the power supply control switch signal is directly connected into the whole vehicle controller, and after the whole vehicle controller receives the power supply control switch signal, a quick power-off instruction is sent to the high-voltage system. When the power-down of the high-voltage system is completed, the whole vehicle controller feeds back the power-off stopping information to the vehicle-mounted terminal, the vehicle-mounted terminal feeds back the power-off stopping information to the vehicle supervision platform, the vehicle supervision platform is pushed to the mobile terminal, a user can check the power-off stopping information of the vehicle through the mobile terminal, and maintenance personnel can perform next maintenance work.
When the low-voltage storage battery of the vehicle is close to full power, the vehicle is not expected to activate automatic power supply, and the charging timing program preset by the vehicle-mounted terminal is short in charging timing close to full power, but the vehicle end is also provided with a path for immediately cutting off high voltage from the aspect of functional safety. When the automatic power supply is not expected to be activated, the vehicle owner can cut off the power supply control switch, and after the whole vehicle controller receives the power supply control switch, a quick power-down instruction is sent to the high-voltage system. When the power-down of the high-voltage system is completed, the whole vehicle controller feeds back the power-off stopping information to the vehicle-mounted terminal, the vehicle-mounted terminal feeds back the power-off stopping information to the vehicle supervision platform, the vehicle supervision platform is pushed to the mobile terminal, a user can check the power-off stopping information of the vehicle through the mobile terminal, and maintenance personnel can perform next maintenance work.
