[0046] In this embodiment, the vehicle power information display system can be installed on new energy vehicles such as electric vehicles to display the power battery power information of the electric vehicle; it can also be installed on traditional vehicles such as fuel vehicles to display the battery power information of the vehicle. In this embodiment, the vehicle power information display system is described using the application of an electric vehicle as an example.

[0047] Reference Figure 1 The vehicle power information display system includes a battery management system BMS, a control module and a DLP lighting module. The battery management system can be a battery management system installed on an electric vehicle; Figure 2 The DLP lighting module is generally installed on a car as the car's headlight; the electronic control unit ECU on an electric car can be used as the control module in this embodiment, or a processor with control functions dedicated to the car's power information display system can be used as the control module. The control module can be integrated inside the DLP lighting module.

[0048] In this embodiment, the battery management system is connected to the power battery and charging module of the electric vehicle so as to obtain power information. Specifically, when obtaining power information, the battery management system can perform the following steps:

[0049] S101A. When the car is detected to be in a charging state, obtain the current state of charge information, charging voltage information, charging current information and charging identification information;

[0050] S102A. Determine the remaining charging time information based on the current state of charge information, charging voltage information, and charging current information;

[0051] S103A. Determine the mileage information based on the current state of charge information;

[0052] S104A. Generate power information based on current state of charge information, charging voltage information, charging current information, charging identification information, remaining charging time information, and cruising range information.

[0053] Steps S101A-S104A are steps executed by the battery management system when charging an electric vehicle.

[0054] In step S101A, the battery management system determines the current state of charge (SOC) of the power battery by detecting parameters such as the voltage of the power battery and combining them with data such as the discharge curve; the battery management system reads the charging voltage information and charging current information from the charging module; the battery management system confirms that the power battery is currently in a charging state and generates charging identification information, which can indicate that the power battery is currently in a charging state. For example, characters such as "normal charging" can be generated as charging identification information.

[0055] In step S102A, the battery management system calculates the amount of electricity required to fully charge the power battery based on the current state of charge information and the performance parameters of the power battery; calculates the charging rate of the power battery based on the charging voltage information and the charging current information; and calculates the time required from the current moment to fully charge the power battery based on the amount of electricity required to fully charge the power battery and the charging rate, that is, the remaining charging time information.

[0056] In step S103A, the battery management system calculates the mileage that the electric vehicle can travel from the current moment to the time when the power battery is discharged to the minimum power, i.e., the cruising range information, based on the current state of charge information and the average power required for the electric vehicle to travel per kilometer.

[0057] In step S104A, the battery management system packages the current state of charge information, charging voltage information, charging current information, charging identification information, remaining charging time information, and cruising range information to obtain power information. Specifically, the power information generated in step S104A includes the current state of charge information, charging voltage information, charging current information, charging identification information, remaining charging time information, and cruising range information.

[0058] In this embodiment, the battery management system may further perform the following steps when acquiring power information:

[0059] S101B. When the car is detected to be in a non-charging state, obtain the current charge state information and non-charging identification information;

[0060] S102B. Determine the mileage information based on the current state of charge information;

[0061] S103B. Generate power information based on the current state of charge information, non-charging identification information, and cruising range information.

[0062] Steps S101B-S103B are steps executed by the battery management system when the electric vehicle is not being charged.

[0063] In step S101B, the battery management system determines the current state of charge (SOC) of the power battery by detecting parameters such as the voltage of the power battery and combining them with data such as the discharge curve. The battery management system confirms that the power battery is currently in a non-charging state and generates non-charging identification information, which can indicate that the power battery is currently in a non-charging state. For example, characters such as "discharging" can be generated as non-charging identification information.

[0064] In step S102B, the battery management system calculates the mileage that the electric vehicle can travel from the current moment to the time when the power battery is discharged to the minimum power, i.e., the cruising range information, based on the current state of charge information and the average power required for the electric vehicle to travel per kilometer.

[0065] In step S103B, the battery management system packages the current state of charge information, the non-charging indicator information, and the cruising range information to obtain the power information. That is, the power information generated in step S103B includes the current state of charge information, the non-charging indicator information, and the cruising range information.

[0066] In this embodiment, the control module generates image information based on the power information obtained by executing steps S101A-S104A or steps S101B-S103B. When the image information is displayed, the content of the power information can be displayed. For example, the control module generates image information based on the power information obtained by executing steps S101A-S104A, and when displayed, its content is as follows: Figure 3 shown.

[0067] After the control module generates the image information, it sends it to the DLP lighting module. The DLP lighting module projects light onto the medium outside the car (usually the ground), and the projected light forms a projected image on the surface of the medium. The projected image displays Figure 3 The content of the image information shown.

[0068] In this embodiment, the automobile power information display system can project the power information onto the medium outside the automobile through the DLP lighting module, thereby generating a projected image that the user can observe outside the car, and understand the power information by observing the projected image. The user does not need to go into the car and start the instrument to understand the power information. The power information can be viewed intuitively, which is convenient for users to use.

[0069] In this embodiment, the DLP light module can count down each time it projects, and stop projecting when the countdown ends, thereby saving power.

[0070] In this embodiment, refer to Figure 2The vehicle power information display system also includes a person sensing module. In this embodiment, an NFC sensing device can be used as the person sensing module. The person sensing module can receive the NFC signal transmitted by the car key and determine the location of the person carrying the car key based on the NFC signal.

[0071] In this embodiment, the person sensing module detects the location of a person carrying a key and uses its own location as the vehicle's location to calculate the distance between the person and the vehicle. The person sensing module sets a distance threshold (e.g., 80 cm). When the distance between the person and the vehicle falls below the threshold, the person sensing module generates a trigger signal and sends it to the battery management system, control module, and / or DLP lighting module.

[0072] In this embodiment, the trigger signal generated by the personnel sensing module can trigger the battery management system to obtain power information, or trigger the control module to generate image information based on the power information, or trigger the DLP lighting module to project an image to the outside of the car based on the image information.

[0073] By setting up a personnel sensing module, there is no need for personnel to perform special operations. As long as the personnel approach the car, the car's power information display system can be triggered to project an image to display the power information, reducing the amount of operations required by personnel to obtain power information and making it easier for personnel to view power information.

[0074] In this embodiment, after the person sensing module detects the position of the person carrying the car key, it uses its own position as the car's position and calculates the direction of the person's position relative to the car's position (for example, left or right in the direction of the car's front). The person sensing module sends this direction of the person's position relative to the car's position to the DLP lighting module, which then determines the display direction of the projected image based on the person's position relative to the car's position.

[0075] For example, the projected image may look like Figure 3 As shown, when the person is on the left side of the vehicle head direction, then Figure 3 The lower part of the image is facing the left side of the front of the vehicle, making it easier for people to observe the power information in the projected image.

[0076] In this embodiment, refer to Figure 2 The vehicle power information display system also includes an obstacle sensing module. In this embodiment, an ultrasonic radar or a laser radar can be used as the obstacle sensing module. The obstacle sensing module can be installed at a location such as the front of the vehicle to detect the location of obstacles such as walls.

[0077] In this embodiment, the projection direction of the DLP light module can be set by default to projection onto the ground, that is, the projection image projected by the DLP light module will be imaged on the ground. Generally, when the length of the ground in front of the DLP light module along the axis of the vehicle reaches a certain threshold (for example, 2 meters), the DLP light module can project a complete projection image onto the ground. When the length of the ground in front of the DLP light module is less than the threshold, for example, when there is a wall in front of the DLP light module at a distance less than the threshold, and the DLP light module projects according to the original projection direction, then the projected image will be partially imaged on the ground and partially imaged on the wall.

[0078] In this embodiment, the obstacle sensing module determines the type and location of the obstacle by emitting ultrasound or laser light and detecting the reflected ultrasound or laser light. If the obstacle sensing module detects a large obstacle such as a wall, and the distance between the obstacle and the vehicle is less than a threshold, the DLP lighting module can adjust the projection direction (for example, upward) to project light toward the wall, ensuring that the projected image is fully displayed on the wall and improving its readability.

[0079] In this embodiment, when the control module generates image information according to the power information, it can specifically perform the following steps:

[0080] S201 performs summary processing on the power information to obtain summary information;

[0081] S202. Generate image information based on the summary information.

[0082] In step S201 , the control module performs summary processing on the power information, deletes part of the original power information, and retains only the other part, thereby obtaining summary information.

[0083] In step S202, when the control module displays the image information generated based on the summary information, the summary information can be displayed. Since the summary information has less information than the power information, the image information generated based on the summary information can be displayed using a smaller medium area than the image information generated based on the power information, thereby facilitating the display of power information in narrow spaces such as parking lots.

[0084] In this embodiment, when the control module executes step S201, that is, the step of summarizing the power information and obtaining summary information, the control module may specifically execute the following steps:

[0085] S20101. Set the corresponding priorities for each part of the power information;

[0086] S20102. According to the distance between the obstacle position and the car position, select several parts of the content according to priority; the number of selected parts of the content is positively correlated with the distance between the obstacle position and the car position;

[0087] S20103. Generate summary information based on all selected partial contents.

[0088] Taking the power information obtained by executing steps S101A-S104A as an example, the power information includes current state of charge information, charging voltage information, charging current information, charging identification information, remaining charging time information and cruising range information.

[0089] In step S20101, the priorities of the respective items are set. For example, if the user is more concerned about information such as the current state of charge and the range, the current state of charge and the range can be set as the highest priority, the remaining charging time and the charging indicator can be set as the middle priority, and the charging voltage and the charging current can be set as the lowest priority.

[0090] In step S20102, the number of partial contents to be selected is determined based on the distance between the obstacle and the vehicle. The greater the distance between the obstacle and the vehicle, the larger the media area available for projection by the DLP lighting module, and the more partial contents that can be selected. For example, if the distance between the obstacle and the vehicle is 3m-5m, four partial contents can be selected; if the distance between the obstacle and the vehicle is 1m-3m, two partial contents can be selected. When selecting multiple partial contents, the ones with the highest priority can be selected.

[0091] In step S20103, the control module generates summary information based on all selected partial contents.

[0092] By executing steps S20101-S20103, the control module can select a suitable number of partial contents from all the partial contents of the power information. The selected partial contents can be fully presented on the medium when projected by the DLP lighting module in the form of a projected image, and have the highest priority, that is, they can convey key information in the power information to the user with higher efficiency, thereby improving the readability of the projected image.

[0093] In this embodiment, after executing steps S201-S202, the control module further executes the following steps:

[0094] S203. Update the image information according to other information in the power information except the summary information.

[0095] In steps S20101-S20103, when the distance between the obstacle and the vehicle is 1m-3m, the control module can select two parts of the content with the highest priority to generate summary information, namely, the current state of charge information and the range information, while the remaining charging time information, charging identification information, charging voltage information, and charging current information with lower priority are not selected. In step S203, the control module can generate new image information based on the unselected remaining charging time information, charging identification information, charging voltage information, and charging current information (specifically, no more than two parts of the content can be preferentially selected according to priority) and send the new image information to the DLP lighting module.

[0096] After the DLP lighting module receives the new image information, it projects the projection image according to the image information before the update for a certain period of time (for example, 5 seconds), and then projects a new projection image to the outside of the car according to the updated image information, thereby displaying the remaining charging time information and charging identification information and other lower priority parts of the power information through the new projection image, thereby realizing the display of each part of the power information through the projection image in order from high to low priority, thereby improving the integrity of the information display of the projection image.

[0097] In this embodiment, refer to Figure 4 , the vehicle power information display method includes the following steps:

[0098] P1. Get power information;

[0099] P2. Generate image information based on power information;

[0100] P3. Through the DLP lighting module, the projected image is projected onto the outside of the car based on the image information.

[0101] The battery management system in the vehicle power information display system of this embodiment can perform step P1, the control module can perform step P2, and the DLP lighting module can perform step P3. By performing steps P1-P3, the functions of the vehicle power information display system can be realized, thereby achieving the same effect as the vehicle power information display system.
