Fig. 1 shows a schematic structural diagram of a vehicle charge state indicating system according to an embodiment of the present application, and for convenience of description, only the portions related to the embodiment are shown, and detailed descriptions are as follows:

referring to fig. 1, a vehicle charging status indicating system includes a charging port 10, a first indicator lamp 30, a second indicator lamp 40, and a charging management unit 50.

The charging port 10 corresponds to at least a first charging mode and a second charging mode. In some embodiments, the charging port 10 integrates at least two modes of dc charging and ac charging, such that the first charging mode is a fast charging mode and the second charging mode is a slow charging mode. The charging port 10 can be arranged at the head of a vehicle or at the tail of the vehicle, and terminals for direct current charging and alternating current charging are integrated in the charging port 10. The first indicator lamp 30 and the second indicator lamp 40 may be disposed at both sides of the charging port 10, for example, the charging port 10, the first indicator lamp 30 and the second indicator lamp 40 are disposed on a front bumper or a rear trunk door, and the charging port 10 is located between the first indicator lamp 30 and the second indicator lamp 40.

Referring to fig. 2, in some other embodiments, the charging port 10 includes at least a first charging port 11 and a second charging port 12, the first charging port 11 and the second charging port 12 are independent of each other, the first charging port 11 corresponds to a first charging mode, and the second charging port 12 corresponds to a second charging mode; the first charging port 11 is a dc charging port, and the second charging port 12 is an ac charging port.

In the vehicle, the first charging port 11 and the second charging port 12 may be both provided at the front end or the rear end of the vehicle, or one may be provided at the front end and the other at the rear end. In addition, the two can be respectively arranged at the left side and the right side of the vehicle, or arranged at the same side of the vehicle. Generally, the dc charging port has 9 terminals, and the ac charging port has 7 terminals.

The first indicator light 30 and the second indicator light 40 are both arranged outside the vehicle, wherein the first indicator light 30 and the second indicator light 40 can be a left steering light, a right steering light, a left small light, a right daytime running light or two independent special indicator lights of the vehicle respectively, each special indicator light can be an indicator light group consisting of one or more light bodies, and the two independent special indicator lights can be arranged on a front bumper or a trunk cover of the vehicle or at two positions; of course, the dedicated indicator lamps may be integrated into the left and right front lamp assemblies 62 and 63 (as shown in fig. 3A), the left and right rear lamp assemblies (not shown), or both the front and rear lamp assemblies. Or other locations on the vehicle where the first indicator light 30 and the second indicator light 40 may be laterally aligned.

The charging management unit 50 controls the first indicator lamp 30 and the second indicator lamp 40 to perform corresponding lamp effects according to the charging state of the vehicle; the charging Management Unit 50 may be a Power Management Unit (PMU), a Battery Management System (BMS), an Electronic Control Unit (ECU), or other lamp driving circuits or chips.

Specifically, the charging state of the vehicle corresponds to the light effect: the first indicator light 30 and the second indicator light 40 are alternately lighted in a mode of gradually changing brightness, in the single lighting process, the first indicator light 30 or the second indicator light 40 is gradually lightened from dark, and the brightness is gradually darkened after reaching the maximum value. In some scenarios, it is colloquially understood that the first indicator light 30 and the second indicator light 40 output light effects in a pattern of alternately illuminated breathing lights while the vehicle is in a charging state.

And when the vehicle is in the first charging mode, the first indicator light 30 lights up first, when the vehicle is in the second charging mode, the second indicator light 40 lights up first, therefore, the user can distinguish two different charging modes according to the different lighting sequence of the indicator lights. And through the lamp effect, the charging state of the vehicle can be displayed more intuitively and dynamically, and the visual experience of a user is improved.

In one example, the first charging port 11 is disposed at a side close to the first indicator lamp 30, and the second charging port 12 is disposed at a side close to the second indicator lamp 40, so that the first indicator lamp 30 close to the first charging port 11 is firstly lighted if it is in the first charging mode, and the second indicator lamp 40 close to the second charging port 12 is firstly lighted if it is in the second charging mode, so that the user can directly distinguish which charging mode is visually.

As shown in fig. 3A, in the present embodiment, the first charging port 11, the second charging port 12, the first indicator lamp 30 and the second indicator lamp 40 are disposed at the middle position of the front bumper 100 between the left and right

front lamp assemblies

62, 63, and the first indicator lamp 30 is close to the first charging port 11 and the second indicator lamp 30 is close to the second charging port 12. Specifically, the second indicator light 40 is farther from the first charging port 11 than the first indicator light 30, and the first indicator light 30 is farther from the second charging port 12 than the second indicator light 40. Therefore, when the first charging port 11 is charged by receiving direct current, the indicator lights are turned on from the first indicator light 30 close to the first charging port 11 to the second indicator light 40, so that a flowing light effect from the first charging port 11 to the second charging port is presented, the flowing direction of the current input from the first charging port 11 is matched, and the charging mode at the moment can be visually confirmed; it is inferred that the second charging port 12 is charged by alternating current, and the similar effect is obtained.

Referring to fig. 3A, 3B and 3C, in a further embodiment, a cover 101 may be further disposed on the vehicle, and the cover 101 is to be covered on the charging port 10 (see fig. 3A), or on the first charging port 11 and the second charging port 12 (see fig. 3B) for protecting the charging port 10, or the first charging port 11 or the second charging port 12 from water, accidental touch, and external impact. In this embodiment, one side of the cover 101 is rotatably connected to the body of the front bumper 100, and the connection position is generally set above the charging port 10, or the first charging port 11 and the second charging port 12, and when the cover 101 needs to be covered, the cover 101 is rotated downward and pressed to cover the body of the front bumper 100, as shown in fig. 3C.

Optionally, the cover 101 and the body of the front bumper 100 are provided with a latch assembly (not shown) that can be snapped into each other, which may be similar to the latch assemblies of the fuel tank cover and the front engine cover; thus, when the cover 101 is pressed to cover the body of the front bumper 100, the cover 101 and the body of the front bumper 100 are fixedly connected by the locking component to prevent accidental opening, as shown in fig. 3C; when it is necessary to open, the cover 101 may be opened by pressing the cover 101 again, or by operating the switch 102 provided on the front bumper 100 to unlock the latch assembly, as shown in fig. 3A and 3B; the switch 102 may be provided in the vehicle cabin.

As shown in fig. 3A and 3B, further, an illumination lamp 103 may be disposed in the area where the charging port 10, or the first charging port 11 and the second charging port 12, are located on the front bumper 100, and the illumination lamp 103 is used to provide illumination after the cover 101 is opened. In the example of fig. 3A, the illumination lamp 103 may be disposed in an area on one side of the charging port 10 or enclosed around the charging port 10. In the example of fig. 3B, the illumination lamp 103 may be disposed in a region between the first charging port 11 and the second charging port 12.

In an alternative embodiment, referring to fig. 3B, 4 and 5, when the vehicle is in the first charging mode, the light starting time T2-start of the second indicator light 40 is later than the previous light starting time T1-start of the first indicator light 30, and the light ending time T2-end of the second indicator light 40 is later than the next light starting time T1 '-start of the first indicator light 30 or earlier than the next light ending time T1' -end of the first indicator light 30; in this mode, the lighting start timing T2-start of the second indicator light 40 is 0.5 seconds to 1 second, preferably 0.75 seconds, later than the lighting start timing T1-start of the first indicator light 30.

Referring to fig. 3B, 6 and 7, when the vehicle is in the second charging mode, the light-on start time T1-start of the first indicator light 30 is later than the light-on start time T2-start of the second indicator light 40 at the previous time, and the light-on end time T1-end of the first indicator light 30 is later than the light-on start time T2 '-start of the second indicator light 40 at the subsequent time or earlier than the light-on end time T2' -end of the second indicator light 40 at the subsequent time. In this mode, the lighting start timing T1-start of the first indicator light 30 is 0.5 seconds to 1 second, preferably 0.75 seconds later than the lighting start timing T2-start of the second indicator light 40.

In an alternative embodiment, referring to fig. 3B, 4 and 5, when the vehicle is in the first charging mode, the light-on start time T2-start of the second indicator light 40 is later than the light-on start time T1-start of the previous first indicator light 30, and is earlier than the maximum brightness time T1-max of the previous first indicator light 30, and the light-on end time T2-end of the second indicator light 40 is earlier than the maximum brightness time T1' -max of the next first indicator light 30; referring to fig. 3B, 6 and 7, when the vehicle is in the second charging mode, the light-on start time T1-start of the first indicator light 30 is later than the light-on start time T2-start of the previous second indicator light 40, and is earlier than the brightness maximum time T2-max of the previous second indicator light 40, and the light-on end time T1-end of the first indicator light 30 is earlier than the brightness maximum time T2' -max of the next second indicator light 40.

Referring to fig. 5 and 7, it can be seen that, in the two charging modes, the change of the brightness of the indicator light from on to maximum brightness and from maximum brightness to off is a smooth change similar to a normal distribution curve, which can provide a good visual experience for the user. In other embodiments, the display brightness of the indicator light during the process from lighting to maximum brightness, and then from maximum brightness to turning off may also be changed smoothly, different from that shown in fig. 5 and 7, or the display brightness may also be changed non-smoothly, for example, may be changed at a constant speed, such as a triangular wave curve, or a sine wave curve.

According to the driving strategy provided by the embodiment, the two indicator lamps are not extinguished at the same time, so that the flowing light effect is visually prominent, and the current flowing visual effect is more obvious.

In an alternative embodiment, referring to fig. 4 and 6, the time interval between the previous lighting ending time and the next lighting starting time of the first indicator light 30 or the second indicator light 40 is T0, T0>0, such as 0.1 second to 0.5 second, preferably 0.25 second. The driving strategy provided by the embodiment can enable the visual effect of current flowing to be more obvious, further improves the visual experience of users and improves the commodity of vehicles.

In one embodiment, when the vehicle is in the first charging mode, the first indicator light 30 and the second indicator light 40 are turned on for a single time period T01; when the vehicle is in the second charging mode, the first indicator lamp 30 and the second indicator lamp 40 are turned on for a single time period T02; where T01< T02, such as T01 for 2.75 seconds and T02 for 3 seconds. This embodiment can judge the charge mode of vehicle more directly perceivedly through the length of the time of lighting a light, removes the trouble that the user looked over the interface that charges, fills electric pile or central control demonstration could confirm the charge mode from.

Referring to fig. 8, in a further embodiment, the vehicle state of charge indication system further comprises: the power feeding port 70, the power feeding port 70 corresponding to at least a first power feeding mode and a second power feeding mode. It is understood that the power feeding port 70 and the charging port 10 may be the same interface or may be separate interfaces. When the two interfaces are independent from each other, the power supply port 70 can be arranged outside the vehicle in a similar manner to the charging port 10; or the device can be arranged in the vehicle cabin, such as a 36V direct current interface and a 220V alternating current interface.

In some embodiments, the power supply port 70 integrates at least two modes of dc power supply and ac power supply, such that the first power supply mode is a fast discharge mode, and the second power supply mode is a slow discharge mode. Terminals for dc discharge and ac discharge are integrated into the power feeding port 70.

Referring to fig. 9, in another embodiment, the power feeding port 70 includes at least a first power feeding port 71 and a second power feeding port 72, wherein the first power feeding port 71 corresponds to a first power feeding mode, and the second power feeding port 72 corresponds to a second power feeding mode; taking the first power supply port 71 as a dc charging port and the second power supply port 72 as an ac charging port as an example, the first power supply mode is a dc discharging mode, and the second charging mode is an ac discharging mode. It is understood that the first power feeding port 71 and the first charging port 11 may be the same interface or may be separate interfaces; the second power feeding port 72 and the second charging port 12 may be the same interface or may be separate interfaces. When the two interfaces are independent of each other, the first power supply port 71 and the second power supply port 72 may be disposed outside the vehicle, or may be disposed in the vehicle cabin, such as a 36V dc interface or a 220V ac interface.

As shown in fig. 10A, in one embodiment, the first indicator light 30, the second indicator light 40, the first power feeding port 71, and the second power feeding port 72 are disposed at the middle position of the front bumper 100 between the left and right

front lamp assemblies

62, 63 with the first indicator light 30 near the first power feeding port 71 and the second indicator light 40 near the second power feeding port 72. Specifically, the second indicator light 40 is farther from the first power supply port 71 than the first indicator light 30, and the first indicator light 30 is farther from the second power supply port 72 than the second indicator light 40. Therefore, when the first power supply port 71 carries out direct current discharge, the indicator lights are turned on firstly from the second indicator light 40 far away from the first power supply port 71 and then to the first indicator light 30, a flowing light effect from the vehicle body far away from the first power supply port 71 to the position close to the first power supply port 71 is presented, the flowing direction of current output from the first power supply port 71 is matched, and the current discharge mode can be visually confirmed; it is reasoned that the second power feeding port 72 also has a similar effect when discharging.

Referring to fig. 10A and 10B, in a further embodiment, a cover 101 may be further disposed on the vehicle, and the cover 101 covers the first power feeding port 71 and the second power feeding port 72, so as to protect the first power feeding port 71 and the second power feeding port 72 from water, accidental contact, and external impact. In this embodiment, one side of the cover 101 is rotatably connected to the body of the front bumper 100 at a position generally above the first power feeding port 71 and the second power feeding port 72, and when the cover 101 needs to be covered, the cover 101 is rotated downward and pressed to cover the body of the front bumper 100, as shown in fig. 10B.

Optionally, the body of the cover 101 and the front bumper 100 are provided with a latch assembly (not shown) that can be snapped into each other, which may be similar to the latch assembly of a fuel tank cover and an engine front cover; thus, when the cover 101 is pressed to cover the body of the front bumper 100, the cover 101 and the body of the front bumper 100 are fixedly connected by the locking component to prevent accidental opening, as shown in fig. 10B; when it is necessary to open, the cover 101 may be opened by pressing the cover 101 again, or by operating the switch 102 provided on the front bumper 100 to unlock the latch assembly, as shown in fig. 10A; the switch 102 may be provided in the vehicle cabin.

As shown in fig. 10A, further, an illumination lamp 103 may be disposed in an area of the front bumper 100 where the first power feeding port 71 and the second power feeding port 72 are located, the illumination lamp 103 being configured to provide illumination after the cover 101 is opened, and in one example, the illumination lamp 103 may be disposed in an area between the first power feeding port 71 and the second power feeding port 72.

Optionally, the charging management unit 50 is further configured to control the first indicator lamp 30 and the second indicator lamp 40 to perform corresponding lamp effects according to the power supply state of the vehicle, wherein the first indicator lamp 30 and the second indicator lamp 40 are alternately turned on in a manner of gradually changing brightness, in a single lighting process, the first indicator lamp 30 or the second indicator lamp 40 is gradually turned on from dark to light, and then gradually turned off after the brightness reaches a maximum value, when the vehicle is in the first power supply mode, the second indicator lamp 40 is turned on first, and when the vehicle is in the second power supply mode, the first indicator lamp 30 is turned on first. In some scenarios, it is colloquially understood that the first indicator light 30 and the second indicator light 40 are output light effects in a pattern of alternately illuminated breathing lights when the vehicle is in a powered state.

In the embodiment, when the vehicle is in the (external) power supply state, the lamp effect opposite to the charging state is displayed, so that whether the vehicle is in the charging state or the power supply state can be intuitively judged, and the power supply mode of the vehicle can be judged according to the lamp effect of the indicator lamp.

In one embodiment, referring to fig. 10A, 11 and 12, when the vehicle is in the first power feeding mode, the light starting time T1-start of the first indicator light 30 is later than the light starting time T2-start of the previous second indicator light 40 and earlier than the maximum brightness time T2-max of the previous second indicator light 40, and the light ending time T1-end of the first indicator light 30 is later than the light starting time T2 '-start of the next second indicator light 40 and earlier than the maximum brightness time T2' -max of the next second indicator light 40. In this mode, the lighting start timing T1-start of the first indicator light 30 is 0.5 seconds to 1 second, preferably 0.75 seconds later than the lighting start timing T2-start of the second indicator light 40.

Referring to fig. 10A, 13 and 14, when the vehicle is in the second power feeding mode, the lighting start time T2-start of the second indicator light 40 is later than the lighting start time T1-start of the previous first indicator light 30 and is earlier than the brightness maximum time T1-max of the previous first indicator light 30, and the lighting end time T2-end of the second indicator light 40 is later than the lighting start time T1 '-start of the next first indicator light 30 and is earlier than the brightness maximum time T1' -max of the next first indicator light 30. In this mode, the lighting start timing T2-start of the second indicator light 40 is 0.5 seconds to 1 second, preferably 0.75 seconds, later than the lighting start timing T1-start of the first indicator light 30.

In an alternative embodiment, referring to fig. 10A, 11 and 12, when the vehicle is in the first power feeding mode, the light starting time T1-start of the first indicator light 30 is later than the previous light starting time T2-start of the second indicator light 40, and the light ending time T1-end of the first indicator light 30 is later than the next light starting time T2 '-start of the second indicator light 40 or earlier than the next light ending time T2' -end of the second indicator light 40. Referring to fig. 10A, 13 and 14, when the vehicle is in the second power feeding mode, the lighting start time T2-start of the second indicator light 40 is later than the lighting start time T1-start of the previous first indicator light 30, and the lighting end time T2-end of the second indicator light 40 is later than the lighting start time T1 '-start of the next first indicator light 30 or earlier than the lighting end time T1' -end of the next first indicator light 30.

Referring to fig. 12 and 14, it can be seen that, in the two power supply modes, the change of the brightness is a smooth change similar to a normal distribution curve during the process from the turning-on of the indicator light to the maximum brightness and then from the maximum brightness to the turning-off of the indicator light, so as to provide a good visual experience for the user. In other embodiments, the display brightness of the indicator light during the process from being turned on to being turned off, and then from being turned on to being turned off may also be changed smoothly, different from the smooth change shown in fig. 12 and 14, and the display brightness may also be changed smoothly, for example, may be changed at a constant speed, such as a triangular wave curve.

In the above two embodiments, the driving strategy of the indicator lamp is set so that the lamp effect of the vehicle in the charging state is opposite to that in the charging state, and it is possible to intuitively determine whether the vehicle is in the charging state or the charging state. In addition, different indicator lamps are firstly turned on in the two power supply modes, and then the turning-on time, the brightness maximum value time and the light-off time of the two indicator lamps are alternately carried out, so that the vision of flowing light effect can be presented to a user, the current flowing direction of the corresponding charging mode can be dynamically displayed, the visual experience of the user is improved, and the commodity of the vehicle is improved.

In one embodiment, in the power feeding state of the vehicle, the interval between the previous lighting end time and the next lighting start time of the first indicator lamp 30 or the second indicator lamp 40 is T0 ', T0' > 0. Where T0 may be the same as or different from T0 ', such as T0' for 0.1 seconds to 0.5 seconds, preferably 0.25 seconds. Similar to the charging state, the embodiment enables the visual effect of current flowing to be more obvious, further improves the visual experience of users, and improves the commodity of vehicles.

In one embodiment, the first power supply mode is a dc power supply mode, and when the vehicle is in the first power supply mode, the first indicator lamp 30 and the second indicator lamp 40 are turned on for a single time period T01'; the second power supply mode is an ac power supply mode, and when the vehicle is in the second power supply mode, the first indicator light 30 and the second indicator light 40 are turned on for a single time period T02 ', where T01 ' < T02 ', for example, T01 ' is 2.5 seconds, and T02 ' is 2.75 seconds. According to the embodiment, the power supply mode of the vehicle can be judged more intuitively according to the length of the lighting time.

In one embodiment, the charging management unit 50 may control the first indicator lamp 30 and the second indicator lamp 40 to be turned on for different periods of time according to the current amount of charge of the vehicle battery when the vehicle is in a charging state or a charging state.

For example, in the case that the battery is sufficiently charged (for example, the charge is above 70%), the single-on time of the first indicator light 30 and the second indicator light 40 is longer, for example, 2.75 seconds to 3.25 seconds, generally 3 seconds is selected, and the maximum brightness time is in the middle of the single-on time.

In the case that the battery capacity is relatively medium (for example, the battery capacity is between 30% and 70%), the single lighting time of the first indicator light 30 and the second indicator light 40 is relatively short, for example, 2 seconds to 2.75 seconds, generally 2.5 seconds is selected, and the time of the maximum brightness is also in the middle of the single lighting time;

in the case of a low battery charge (e.g., less than 30%), the first indicator light 30 and the second indicator light 40 are lit for a short time, e.g., 1.5 seconds to 2 seconds, typically 1.75 seconds, and the time of the maximum brightness is also in the middle of the single lighting time. Therefore, according to the embodiment, the electric quantity condition of the vehicle can be intuitively judged according to the length of the lighting time, and the time required by charging or power supply is pre-judged.

In one embodiment, the charging management unit 50 may control the single lighting colors of the first indicator light 30 and the second indicator light 40 to be different according to the current amount of the vehicle battery in the charging state or the charging state of the vehicle. For example, when the battery is sufficiently charged (for example, the charge is above 70%), the first indicator light 30 and the second indicator light 40 are green lights when the battery is charged or powered. When the battery is charged or energized, the first indicator light 30 and the second indicator light 40 show orange lights when the battery is charged or energized (for example, the battery is charged between 30% and 70%). In the case where the battery is low (for example, 30% or less), the first indicator light 30 and the second indicator light 40 show red lights when the battery is charged or energized. Therefore, the embodiment can visually judge the electric quantity condition of the vehicle by lighting the lamp, and pre-judge the time length required by charging or power supply.

Further, the color of the single-time lighting of the dc charging (powering) mode and the ac charging (powering) mode may also be different, for example, the gray scale of the color presented by the ac charging (powering) mode is higher than that of the dc charging (powering) mode under the same battery power, for example, the dc charging (powering) mode indicator light presents green color than the ac charging (powering) mode indicator light presents green color when the battery power is 80%, and other power may be analogized in this way, which is not illustrated one by one.

As shown in fig. 10A and 10B, further, an illumination lamp 103 may be disposed in the area where the power supply port 70, or the first power supply port 71 and the second power supply port 72 are located on the front bumper 100, and the illumination lamp 103 is used to provide illumination after the cover 101 is opened.

In some scenarios, it is colloquially understood that the first indicator light 30 and the second indicator light 40 are output light effects in a pattern of alternately illuminated breathing lights when the vehicle is in a powered state.

In the embodiment, when the vehicle is in the (external) power supply state, the power supply mode of the vehicle can be judged through the lamp effect of the indicating lamp by a user, and the power supply state of the vehicle can be displayed more intuitively through the lamp effect, so that the indicating lamp is more powerful, the visual experience of the user is improved, and the commodity of the vehicle is improved.

The embodiment enables the visual effect of current flowing to be more obvious, further improves the visual experience of users and improves the commodity of vehicles.

In one embodiment, the first power supply mode is a dc power supply mode, and when the vehicle is in the first power supply mode, the first indicator lamp 30 and the second indicator lamp 40 are turned on for a single time period T01'; the second power supply mode is an ac power supply mode, and when the vehicle is in the second power supply mode, the first indicator light 30 and the second indicator light 40 are turned on for a single time period T02 ', where T01 ' < T02 ', for example, T01 ' is 2.5 seconds, and T02 ' is 2.75 seconds.
