< method examples >

Fig. 2 is a flowchart illustrating a power supply control method according to an embodiment, which is implemented by a power supply control apparatus of an electric vehicle. The electric vehicle may be the vehicle 3000 shown in fig. 1.

In a possible implementation manner, the power supply control device may be preferably disposed inside the battery, as a processing module inside the battery, for example, may be a chip in the battery, so as to control a power supply program of the power supply module in the battery. The power supply module in the battery can be obtained by connecting a plurality of power supply units in series. In other possible implementations, the power supply control device may also be disposed outside the battery.

As shown in fig. 2, the power supply control method of the present embodiment may include steps S210 to S220 as follows:

step S210, receiving a car use request from the terminal device.

The terminal device may be the terminal device 1000 shown in fig. 1.

In this embodiment, before the user uses the electric vehicle, that is, the electric vehicle is in an unused state, the battery is in a low power consumption state, and the main control module of the electric vehicle is not powered, so that the power consumption of the battery can be reduced. And when the user uses the electric motor car, just begin to supply power to the host system to the user can normal use electric motor car.

In this embodiment, the battery does not supply power to the main control module in the low power consumption mode, but the power supply control device may respond to the external communication function during this period. Therefore, when the user needs to use the electric vehicle, the user can send a vehicle using request by operating the terminal equipment.

In a feasible implementation manner, the terminal device may be a smart phone of the user, a corresponding application program may be installed in the smart phone, and the user may send a vehicle using request through the application program.

In this embodiment, since the main control module of the electric vehicle is not powered when the user requests to use the vehicle, the server is inconvenient to notify the corresponding main control module to execute the corresponding operation based on the vehicle use request sent by the terminal device. Therefore, the terminal device may not send the vehicle use request to the server, but directly send the vehicle use request to the electric vehicle, specifically to the power supply control device in the electric vehicle according to this embodiment.

The server may be the server 2000 shown in fig. 1.

Based on this, the power supply control device of the electric vehicle can receive the vehicle using request sent by the terminal device. After receiving the vehicle use request, the power supply control device may execute the following step S220 to control the battery to start supplying power to the main control module.

In this embodiment, the terminal device and the power supply control apparatus can communicate with each other, and the corresponding communication method may be at least any one of the following two communication methods:

in the method 1, the terminal device establishes a communication connection with the power supply control device, and then communicates with the power supply control device based on the communication connection.

In the mode 2, the terminal device directly performs near field communication with the power supply control device without establishing communication connection in advance.

In detail, for the above mode 1:

in an embodiment of the present disclosure, before the step S210, receiving a car use request sent by a terminal device, the method further includes the following step a:

and step A, establishing communication connection with the terminal equipment through the communication module according to the connection information corresponding to the communication module in the electric vehicle, which is provided by the terminal equipment.

In this embodiment, the terminal device needs to establish a communication connection with the power supply control device first, so that the terminal device needs to acquire connection information for connecting the power supply control device.

The communication connection technology can be a bluetooth communication technology, a Wi-Fi wireless communication technology, and the like. In this way, a corresponding communication module may be provided in the electric vehicle, for example, the communication module may be a bluetooth chip for supporting bluetooth connection. The terminal device can further establish communication connection with the power supply control device based on the Bluetooth chip.

In a possible embodiment, the communication module can be arranged inside the battery, and the communication module can be connected to the power supply control device by a wire. In other possible implementations, the communication module may also be disposed outside of the battery.

In a possible implementation, different electric vehicles have unique identification, as do the communication modules in the electric vehicles. Based on this, an indication that the unique identification information can be acquired can be provided to the user through the electric vehicle, for example, the indication can be a two-dimensional code or the like, so that the terminal device can acquire the unique identification information through the indication, thereby acquiring the connection information corresponding to the communication module.

In a feasible implementation mode, a two-dimensional code corresponding to the only identification of the electric vehicle can be printed on the electric vehicle, a user can scan the two-dimensional code by using the terminal device, and a code scanning result is sent to the server, so that the server can determine the electric vehicle to be used by the user according to the code scanning result, and then the stored connection information of the communication module in the electric vehicle is read and returned to the terminal device. After receiving the connection information, the terminal equipment can establish communication connection with the power supply control device.

In another feasible implementation manner, a two-dimensional code corresponding to the unique identifier of the communication module in the electric vehicle can be printed on the electric vehicle, and a user can scan the two-dimensional code by using the terminal device. As described above, the code scanning result may be sent to the server so that the server returns the corresponding connection information. In one embodiment, the terminal device may also obtain the connection information directly according to the code scanning result.

Further, the terminal device may connect to the communication module based on the obtained connection information, thereby establishing a communication connection with the power supply control apparatus through the communication module. Therefore, in step a, the power supply control device may establish a communication connection with the terminal device held by the user through the corresponding communication module based on the connection information provided by the terminal device.

Based on this, the step S210 receives the car use request from the terminal device, and includes: and receiving a vehicle using request sent by the terminal equipment based on the communication connection.

In this embodiment, after the communication connection is established between the terminal device and the power supply control device, the terminal device may send a vehicle use request to the power supply control device through the communication connection based on a user operation.

Based on the above, in an embodiment of the present disclosure, the step a of establishing a communication connection with the terminal device through the communication module according to the connection information corresponding to the communication module in the electric vehicle, which is provided by the terminal device, includes:

and establishing Bluetooth communication connection with the terminal equipment through the Bluetooth chip according to the connection information corresponding to the Bluetooth chip in the electric vehicle, which is provided by the terminal equipment.

In this embodiment, the connection information and the vehicle use request are transmitted to the power supply control device by the terminal device in the form of a bluetooth signal.

In this embodiment, based on the bluetooth module inherent in the terminal device and the bluetooth chip inherent in the electric vehicle, the bluetooth communication connection may be established between the terminal device and the power supply control device, so that the terminal device may issue the vehicle use request to the power supply control device based on the bluetooth communication technology.

In addition, the user only needs to simply operate the terminal device, even if the Bluetooth communication connection is realized, the user experience is better, and the user does not need to approach the terminal device to the communication module of the electric vehicle in the mode 2.

In detail, with respect to the above-described mode 2:

in an embodiment of the present disclosure, the receiving a car-using request sent by a terminal device includes: and receiving a car using request sent by the terminal equipment based on the near field communication technology.

In this embodiment, the terminal device can directly perform near field communication with the power supply control device without establishing communication connection with the power supply control device.

In detail, Near Field Communication (NFC) is a short-range high-frequency wireless Communication technology. Devices using NFC technology can exchange data in close proximity to each other.

In this embodiment, the user can remove terminal equipment in order to change terminal equipment's spatial position to make the NFC chip in the terminal equipment be close to the NFC chip in the electric motor car, under the condition that two NFC chips are close enough, terminal equipment can be based on inside NFC chip, can send the NFC chip in the electric motor car with the car request, thereby send for the power supply controlling means who connects the NFC chip.

Therefore, the embodiment can simplify the interaction between the terminal equipment and the power supply control device, simplify the power supply control process, avoid the need of setting indication information for acquiring the connection information on the electric vehicle, simplify the information interaction between the terminal equipment and the server, reduce the data processing pressure of the server, avoid the data processing delay caused by poor network and improve the vehicle response speed.

And step S220, responding to the vehicle using request, and controlling a battery of the electric vehicle to start supplying power to a main control module of the electric vehicle.

The power supply control device can control the battery to start supplying power to the main control module in response to the vehicle using request sent by the terminal equipment. The main control module can execute corresponding operation after being electrified so as to support a user to use the electric vehicle. For example, after the main control module is electrified, the battery can be controlled to supply power to the motor of the electric vehicle, so that the rotation of the motor can provide power assistance for riding of a user.

In an embodiment of the present disclosure, in step S220, the controlling a battery of an electric vehicle to start supplying power to a main control module of the electric vehicle includes: and switching the working mode of the battery of the electric vehicle from a first mode to a second mode. Wherein the battery does not supply power to the master control module in the first mode; the battery supplies power to the main control module in the second mode.

In this embodiment, when the user uses the vehicle, the battery is switched from the first mode to the second mode to exit the low power consumption mode and enter the discharging mode.

In this embodiment, the battery may have at least the two operating modes, and the operating state of the battery may be switched as needed by controlling the operating mode of the battery to be switched between the first mode and the second mode, so that when a user uses the vehicle, the operating state of the battery may be switched to start supplying power to the main control module.

In the embodiment, a power supply control device of an electric vehicle receives a vehicle using request sent by a terminal device; and responding to the vehicle using request, and controlling a battery of the electric vehicle to start supplying power to a main control module of the electric vehicle so as to support the use of the electric vehicle by a user. Because when the user requests to use the vehicle, the battery starts to supply power to the main control module of the electric vehicle instead of supplying power to the main control module all the time, the power consumption of the battery is reduced, frequent replacement of the battery is avoided, and the battery endurance time is prolonged.

In addition, this embodiment is just for the power supply of host system when the user requests to use the car, and electrified host system just can support the user and normally use the electric motor car, and does not have the user to request not to supply power to host system under the circumstances of using the car for host system is uncharged, and the user can not normally use the electric motor car this moment. That is, in this embodiment, whether the battery starts to supply power to the main control module may be used as an identifier of whether the user can use the electric vehicle, and whether the lock is unlocked may not be used as an identifier of whether the user can use the electric vehicle. Therefore, based on the power supply control mode provided by the embodiment, the lock can be omitted from the electric vehicle, so that the normal use of the electric vehicle by a user can be supported, and meanwhile, the cost can be correspondingly saved.

In this embodiment, the user can begin to supply power to the main control module when requesting to use the vehicle, and the main control module is always electrified for ensuring that the user can normally use the vehicle during the user using the vehicle. After the user finishes using the electric vehicle, the electric vehicle is always in a standby state or an unused state, and power can not be supplied to the main control module during the standby state or the unused state, so that the power consumption of the battery is reduced. Based on this, in a feasible implementation manner, when the user finishes using the vehicle, the terminal device may send a vehicle returning request, and the power supply control device may control the battery to stop supplying power to the main control module based on the vehicle returning request.

The implementation manner of the power supply control device for controlling the battery to stop supplying power to the main control module based on the vehicle returning request can be at least any one of the following two implementation manners:

in the mode a, the terminal equipment directly sends a vehicle returning request to the power supply control device.

In the mode b, the terminal equipment sends a car returning request to the server, the server triggers the main control module, and the main control module informs the power supply control device to stop supplying power to the power supply control device.

In detail, with respect to the above-described mode a:

in an embodiment of the present disclosure, after controlling the battery of the electric vehicle to start supplying power to the main control module of the electric vehicle at the step S220, the method further includes the following steps B1 to B2:

and step B1, receiving a car returning request sent by the terminal equipment.

Based on the above, after the user sends the car returning instruction, the terminal device may send the car returning request to the power supply control device based on the established communication connection, or send the car returning request to the power supply control device based on the near field communication technology.

Normally, the terminal device already establishes a communication connection with the power supply control device when the vehicle usage request is sent, for example, a bluetooth communication connection is established, so that the communication connection can be continuously maintained during the vehicle usage of the user. In this way, when the user returns the car, the terminal device may send a car return request to the power supply control device based on the established communication connection.

In addition, the terminal equipment can also send a car returning request to the power supply control device based on the near field communication technology.

And step B2, responding to the car returning request, and controlling the battery to stop supplying power to the main control module.

In this embodiment, the power supply control device may control the battery to stop supplying power to the main control module based on the vehicle change request, and may specifically be implemented by switching the operating state of the main control module.

In detail, with respect to the above-described mode b:

in an embodiment of the present disclosure, after controlling the battery of the electric vehicle to start supplying power to the main control module of the electric vehicle at the step S220, the method further includes the following steps C1 to C2:

and step C1, receiving the notification information sent by the main control module based on the car returning request sent by the terminal device to the server.

In this embodiment, since the main control module is always electrified during the vehicle-using period of the user, the main control module and the server maintain communication connection, the server can trigger the main control module, and the main control module notifies the power supply control device to stop supplying power to the power supply control device.

For the situation that the communication connection is established when the user uses the vehicle, the communication connection is established when the user uses the vehicle so as to send a vehicle using request to enable the battery to start supplying power to the main control module, even if the communication connection is disconnected during the subsequent vehicle using period, the battery still maintains the power supply to the main control module without influencing the normal use of the electric vehicle by the user, and therefore the situation that the established communication connection is interrupted or is not stable enough may exist.

The communication connection is not passed through by the server, so that the method and the device are suitable for the situation that the established communication connection is disconnected or unstable enough and needs to be established again when the user returns the vehicle, and the accurate and quick operation of the vehicle returning operation can be still ensured under the situation.

For the situation that the user sends the vehicle using request through the near field communication technology when using the vehicle so that the battery starts to supply power to the main control module, the near field communication technology requires that the terminal device is close to the communication module of the electric vehicle, so that the user needs to move the terminal device again if the user sends the vehicle returning request through the near field communication technology when returning to the vehicle.

In other embodiments of the present disclosure, based on different actual application requirements, the server may also trigger the main control module to notify the power supply control device that power is no longer supplied to the main control module at a specific time or under a specific condition after the user finishes using the vehicle based on a set program.

As shown in fig. 3, the present embodiment provides a power supply control method implemented by a power supply control apparatus of an electric vehicle, which may include the following steps S310 to S350.

And S310, establishing Bluetooth communication connection with the terminal equipment through the Bluetooth chip according to the connection information corresponding to the Bluetooth chip in the electric vehicle, which is provided by the terminal equipment.

And step S320, receiving a vehicle using request sent by the terminal device based on the Bluetooth communication connection.

Step S330, responding to the vehicle using request, switching the working mode of the battery of the electric vehicle from a first mode to a second mode, so that the battery starts to supply power to a main control module of the electric vehicle.

Wherein the battery does not supply power to the master control module in the first mode; the battery supplies power to the main control module in the second mode.

Step S340, receiving notification information sent by the main control module based on the car return request sent by the terminal device to the server.

Step S350, in response to the notification information, switching the working mode of the battery of the electric vehicle from the second mode to the first mode, so that the battery stops supplying power to the main control module.

In the embodiment, the battery starts to supply power to the main control module of the electric vehicle instead of supplying power to the main control module all the time when the user requests to use the vehicle, so that the power consumption of the battery is reduced, and the frequent replacement of the battery is avoided.
