Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, an electric vehicle 100 includes a vehicle frame 11, a suspension assembly 12, a traveling assembly 13, a power assembly (not shown), and a vehicle power supply 14. Specifically, suspension assembly 12 is coupled to frame 11, and undercarriage assembly 13 is coupled to frame 11 via suspension assembly 12. The power assembly 14 is at least partially arranged on the frame 11, the power assembly 14 is in transmission connection with the walking assembly 13, the power assembly comprises a driving motor (not shown in the figure), the whole vehicle power supply 14 is in transmission connection with the walking assembly 13 through the driving motor, and the whole vehicle power supply 14 is at least partially arranged on the frame 11.

As shown in fig. 2, as an implementation manner, the electric vehicle 100 further includes an electrical system 15, the electrical system 15 is capable of establishing a connection with the charging pile 200, and the electrical system 15 includes a charging module 151 and a detection module 152. Wherein the charging pile 200 charges the entire vehicle power supply 14 through the charging module 151. Specifically, the detection module 152 is provided independently of the charging module 151, so that the detection module 152 can still be activated when the charging module 151 is in a sleep state or an off state, and detect whether the charging pile 200 is connected to the electric vehicle 100 through the detection module 152. It should be noted that the charging module 15 may be an in-vehicle charger. Further, in order to reduce the power consumption of the entire vehicle power source 14 when the electric vehicle 100 is in the power-on state, the charging module 151 is in the sleep state or the off state. While the electric vehicle 100 receives the power-on instruction, the detection module 152 is started in response to the power-on instruction and detects a detection signal output by the charging pile 200. If the detection module 152 receives the detection signal, the electric vehicle 100 and the charging pile 200 are in a connected state.

In the related art, the detection module 152 is built in the charging module 151. When the electric vehicle 100 is in the power-on state, if it is required to detect whether the electric vehicle 100 and the charging pile 200 are in the connection state in real time through the detection module 152, the charging module 151 cannot enter the sleep state or the off state, so that the energy consumption of the electric vehicle 100 is increased.

Through the above arrangement, the charging module 151 is only started during the charging process of the electric vehicle 100, and when the electric vehicle 100 is in the power-on state, the working current of the detection module 152 is no longer transmitted or provided through the charging module 151, so that the driving safety is ensured, meanwhile, the power consumption of the electric vehicle 100 is reduced, and the driving range of the electric vehicle 100 is prolonged.

As shown in fig. 3, as an implementation manner, the electrical system 15 further includes a control module 153, the control module 153 is connected to the detection module 152, and the detection module 152 is disposed independently from the control module 153. Further, when the electric vehicle 100 is in the power-on state and the detection module 152 receives the detection signal, the detection module 152 transmits the detection signal to the control module 153, and the control module 153 controls the electric vehicle 100 to be in the disable state in response to the detection signal. Through the above arrangement, the detection module 152 can operate independently in the power-on state of the electric vehicle 100, so that the power consumption of the electric vehicle 100 is reduced, and the endurance mileage of the electric vehicle 100 is prolonged.

Specifically, when the electric vehicle 100 is in the disabled state, the control module 153 controls the electric vehicle 100 to execute an early warning prompt, where the early warning prompt at least includes: audio alerts, image alerts, or vibration alerts.

As shown in fig. 4, as another implementation manner, the detection module 152 can be embedded in the control module 153, and the detection module 152 and the control module 153 are configured as a same start circuit, so that the integration degree of the electrical system 15 is improved. Specifically, under electric vehicle 100 is in a charging state, charging module 151 outputs a wake-up signal to control module 153, and since detection module 152 and control module 153 are set to be the same start circuit, detection module 152 starts in response to the wake-up signal at the same time, so that detection module 152 can receive the detection signal output by charging pile 200, thereby determining whether electric vehicle 100 is connected to charging pile 200. If the electric vehicle 100 is connected to the charging pile 200, the entire vehicle power supply 14 performs a charging operation. Through the above arrangement, the power consumption of the electric vehicle 100 is reduced, the driving range of the electric vehicle 100 is prolonged, and the space occupancy rate of the components in the electrical system 15 is optimized.

As shown in fig. 4, as an implementation manner, the electrical system 15 further includes a battery management module 154, the battery management module 154 is connected to the detection module 152, and the battery management module 154 is connected to the charging module 151 in addition to the detection module 152. Further, when the electric vehicle 100 is connected to the charging post 200, the charging post 200 outputs a wake-up signal to the charging module 151, and the charging module 151 wakes up the control module 153 and the battery management module 154 in response to the wake-up signal.

Specifically, when the charging post 200 is connected to the charging module 151, the charging post 200 outputs a wake-up signal to the charging module 151, and the charging module 151 receives the wake-up signal and outputs low-voltage auxiliary power to the detection module 152, the control module 153, and the battery management module 154, respectively, in response to the wake-up signal. At this time, the detection module 152 starts and receives the detection signal output by the charging pile 200. Further, the detection module 152 transmits the detection signal to the battery management module 154. When the battery management module 154 is activated by the low-voltage auxiliary source and receives the detection signal, the battery management module 154 sends a charging instruction to the charging module 151, and the entire vehicle power supply 14 performs a charging operation.

As shown in fig. 5, as another implementation manner, the detection module 152 is embedded in the battery management module 154, and the detection module 152 and the battery management module 154 are configured as a same start circuit, so as to improve the integration degree of the electrical system 15. Specifically, when the electric vehicle 100 is in a charging state, the charging module 151 outputs a wake-up signal to the battery management module 154, and since the detection module 152 and the battery management module 154 are set to be the same start circuit, the detection module 152 is started in response to the wake-up signal at the same time, so that the detection module 152 can receive the detection signal output by the charging pile 200, and thus, whether the electric vehicle 100 is connected to the charging pile 200 is determined. If the electric vehicle 100 is connected to the charging pile 200, the entire vehicle power supply 14 performs a charging operation. Through the above arrangement, the power consumption of the electric vehicle 100 is reduced, the driving range of the electric vehicle 100 is prolonged, and the space occupancy rate of the components in the electrical system 15 is optimized.

As shown in fig. 5, it can be understood that a detection channel 155 is established between the detection module 152 and the charging pile 200, and a wake-up channel 156 is established between the charging module 151 and the charging pile 200. Wherein both the detection channel 155 and the wake-up channel 156 are connected to the electric vehicle 100 through the same connection port, i.e. both the detection channel 155 and the wake-up channel 156 are set to be connected or disconnected at the same time.

As an implementation manner, a first conduction manner and a second conduction manner are provided between the detection module 152 and the charging pile 200. The first conduction mode is set to be electronically controlled to conduct, and the second conduction mode is set to be mechanically controlled to conduct. Specifically, in the case of the first conduction mode, the detection module 152 is connected to the control module 153, and when the electric vehicle 100 receives a power-on command, the control module 153 controls the detection channel 155 to conduct in response to the power-on command, so that the detection channel 155 can transmit a detection signal output by the charging pile 200. If the detection module 152 receives the detection signal, the detection module 152 transmits the detection signal to the control module 153, and the control module 153 controls the electric vehicle 100 to be in the disabled state in response to the detection signal. Through the setting, the safety of the electric vehicle 100 is improved, and the electric vehicle 100 or the charging pile 200 is prevented from being damaged. Meanwhile, the energy consumption of the electric vehicle 100 in the power-on state is reduced, and the driving range of the electric vehicle 100 is prolonged.

As another implementation manner, in the case of the second conduction manner, the detection module 152 is connected to the charging pile 200 and establishes the detection channel 155. Wherein, a switch is arranged on the detection channel 155, and the switch is arranged to be changed according to the working state of the electrical system 15, so as to control the opening or closing of the switch, and further control the disconnection or connection of the detection channel 155. Specifically, when the electric vehicle 100 receives a power-on instruction, the electric system 15 is started in response to the power-on instruction, and the switch is controlled to be closed or opened by the operating state of the electric system 15.

Specifically, the switch is provided as a thermal switch capable of achieving expansion with heat and contraction with cold in the working environment of the electrical system 15. When electric system 15 worked, the switch was heated the inflation and is produced deformation to make the switch closed, and then detection channel 155 is in the on-state, and detection channel 155 can transmit the detected signal by filling electric pile 200 output. If the detection module 152 receives the detection signal, the detection module 152 transmits the detection signal to the control module 153, and the control module 153 controls the electric vehicle 100 to be in the disabled state in response to the detection signal.

Specifically, the switch is provided as an elastic member. The switch is at least partially arranged on the electric vehicle 100 and is connected with the port of the charging pile 200. In the case where the electric vehicle 100 is connected to the charging pile 200, the switch is closed to communicate the detection passage 155. It is understood that the switch is automatically turned off in the case where the electric vehicle 100 is disconnected from the charging pile 200.

Through the setting, the safety of the electric vehicle 100 is improved, and the electric vehicle 100 or the charging pile 200 is prevented from being damaged. While driving safety is ensured, energy consumption of the electric vehicle 100 in a power-on state is reduced, and the endurance mileage of the electric vehicle 100 is prolonged.

As shown in fig. 6, as another implementation manner, a signal transmission channel 157 is established between the detection module 152 and the charging pile 200, and the signal transmission channel 157 is used for transmitting a wake-up signal in addition to the detection signal. Thus, when the electric vehicle 100 is in the power-on state, the detection module 152 receives the detection signal output by the charging pile 200 through the signal transmission channel 157 and transmits the detection signal to the control module 153, and the control module 153 controls the electric vehicle 100 to be in the disable state in response to the detection signal. Through the setting, the safety of the electric vehicle 100 is improved, and the electric vehicle 100 or the charging pile 200 is prevented from being damaged. In the present embodiment, the detection channel 155 and the wake-up channel 156 are integrated into one signal transmission channel 157 capable of simultaneously transmitting the detection signal and the wake-up signal, so that the degree of integration of the electric vehicle 100 is improved.

In the present embodiment, the detection module 152 is disposed independently from the charging module 151, so that the electric vehicle 100 does not need to wake up the charging module 151 in the power-on state, and the detection module 152 can receive the detection signal output by the charging pile 200, so that the control module 153 can determine whether the charging pile 200 is connected to the electric vehicle 100 in response to the detection signal. In the above embodiments, various arrangements of the detection module 152 are shown. It is understood that the embodiments that the charging module 151 is in a sleep or off state while the detection module 152 is in a normal operation and receives the detection signal when the electric vehicle 100 is in the power-on state are all within the scope of the present application.
