Background

With the continuous development of automobile technology and the increasing material demand of people, more and more vehicle-mounted terminals are applied to automobiles. The in-vehicle terminal is generally electrically connected to a vehicle power source for a long period of time. Generally, when a vehicle starts, the in-vehicle terminal starts charging until the vehicle is turned off. However, when the vehicle is started by ignition, the vehicle may be ignited repeatedly, which may cause repeated charging and power failure of the vehicle-mounted terminal. Since the vehicle charges the in-vehicle terminal after the vehicle is started, repeated charging near the full-charge voltage for a long time may occur, causing the battery to bulge and be damaged.

Fig. 3 is a software configuration block diagram of the in-vehicle terminal 200 according to the embodiment of the present application.

The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android System is divided into four layers, which are an application layer (System Apps), an application Framework layer (Java API Framework), a System runtime layer (Native), and a Kernel layer (Linux Kernel), from top to bottom.

The application layer may include a series of application packages.

As shown in fig. 3, the application packages may include calendar, telephony, maps, navigation, WLAN, bluetooth, music, etc. applications.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 3, the application framework layers may include a window manager, content provider, view system, phone manager, resource manager, notification manager, and the like.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, phone calls made and received, etc.

The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications.

It should be noted that, the configuration of different vehicle-mounted terminals may be different, and therefore, the above-mentioned fig. 2 to fig. 3 are only used as an exemplary description, and the present application is not limited to this.

The embodiment of the application provides a charging method of an in-vehicle terminal, and fig. 4 exemplarily shows a flow of the charging method of the in-vehicle terminal, which can be executed by the in-vehicle terminal 200 shown in fig. 2. The flow may also be executed by the processor 240 in the in-vehicle terminal 200. The vehicle-mounted terminal is implemented as an example as follows. The specific process is as follows:

401, when detecting that the first power supply interface for supplying power to the vehicle-mounted terminal by the vehicle is in a power supply state, starting the vehicle-mounted terminal.

After the vehicle is started, the first power supply interface for supplying power to the vehicle-mounted terminal by the vehicle is changed from a power supply stop state to a power supply state, so that power is supplied to the vehicle-mounted terminal through the first power supply interface. And when the vehicle-mounted terminal detects that the first power supply interface is in a power supply state, the vehicle-mounted terminal is started.

And 402, acquiring the current residual capacity of the energy storage device of the vehicle-mounted terminal.

In some embodiments, the current remaining capacity of the energy storage device of the vehicle-mounted terminal may be acquired. As an example, the remaining energy value of the energy storage device of the vehicle-mounted terminal may be used as the current remaining power. For example, the energy storage device of the in-vehicle terminal may be a battery. And if the acquired residual storage value of the battery of the vehicle-mounted terminal is 2000 milliamperes, taking 2000 milliamperes as the current residual capacity of the battery.

And 403, when the current residual capacity of the energy storage device is larger than the first set threshold, not charging the energy storage device.

In some embodiments, the first set threshold may be set according to user requirements. In some scenarios, the first set threshold may be a set power threshold. After the current remaining power is obtained, the current remaining power may be compared with a set power threshold. When the current remaining capacity is greater than the set capacity threshold, the energy storage device is not charged, as shown in fig. 5. For example, the user sets the first set threshold to 1500 milliamps. When the current residual capacity is 2000 milliampere, if the current residual capacity is larger than a first set threshold, the energy storage device is not charged. In other scenarios, the first set threshold may be a percentage of the remaining power. After the current remaining capacity is obtained, the percentage of the current remaining capacity can be determined according to the obtained current remaining capacity and the total energy storage value of the energy storage device, and then the percentage of the current remaining capacity is compared with a first set threshold value. When the percentage of the current remaining capacity is greater than the first set threshold, the energy storage device is not charged, as shown in fig. 6. For example, the first set threshold is 50%. When the current residual capacity is 2000 milliamperes and the total storage capacity of the energy storage device is 3000 milliamperes, the percentage of the current residual capacity is 66.6%, and is greater than the first set threshold value. Thus, the energy storage device is not charged.

And 404, when the current residual capacity of the energy storage device is less than or equal to a first set threshold, charging the energy storage device through the first power supply interface.

In some scenarios, the first set threshold may be a set power threshold. After the current remaining power is obtained, the current remaining power may be compared with a set power threshold. When the current remaining power is less than or equal to the set power threshold, the energy storage device is charged through the first power supply interface, as shown in fig. 7. For example, the user sets the first set threshold to 1500 milliamps. When the current remaining capacity of the energy storage device is 1000 ma, and the current remaining capacity is less than or equal to a first set threshold, the energy storage device needs to be charged through the first power supply interface. In other scenarios, the first set threshold may be a percentage of the remaining charge. After the current remaining capacity is obtained, the percentage of the current remaining capacity can be determined according to the obtained current remaining capacity and the total energy storage value of the energy storage device, and then the percentage of the current remaining capacity is compared with a first set threshold value. When the percentage of the current remaining capacity is smaller than or equal to the first set threshold, the energy storage device is charged through the first power supply interface, as shown in fig. 8. For example, the first set threshold is 50%. When the current residual capacity is 1000 milliamperes and the total storage capacity of the energy storage device is 3000 milliamperes, the percentage of the current residual capacity is 33.3%, and is smaller than the first set threshold value. Therefore, the vehicle-mounted terminal charges the energy storage device through the first power supply interface.

In some embodiments, the first power supply interface is electrically connected to the energy storage device. The vehicle-mounted terminal can obtain electric energy from the first power supply interface and store the obtained electric energy into the energy storage device.

Based on the scheme, when the vehicle is started, the current residual capacity of the energy storage device of the vehicle-mounted terminal is obtained firstly, and when the residual capacity is smaller than a set threshold value, the energy storage device of the vehicle-mounted terminal is charged. And when the residual electric quantity of the vehicle-mounted terminal is greater than the set threshold value, the energy storage device of the vehicle-mounted terminal is not charged. The scheme avoids the problem that the vehicle-mounted terminal is easy to start charging until the vehicle is flamed out and stops charging when the vehicle is started, the problem that the battery bulges and threatens safety due to repeated charging near the full-power voltage is solved, and the problem that the vehicle repeatedly charges and cuts off the power supply for the vehicle-mounted terminal when the vehicle is repeatedly ignited and then the performance of the battery is influenced is solved.

In some scenes, the vehicle has the condition of high and low temperature in the use process, however, the display electric quantity of the vehicle-mounted terminal cannot be calibrated to the electric quantity corresponding to the current temperature and voltage, and the electric quantity of the vehicle-mounted terminal which is shut down last time still can be maintained. In the prior art, the electric quantity of the vehicle-mounted terminal is calibrated only when the electric quantity is high or low. The display electric quantity can follow the calibration electric quantity after starting up, and when the calibration electric quantity is lower than the display electric quantity and is charged, the electric quantity can not be reduced, so that electric quantity errors occur, and the display accuracy is influenced. Specifically, the voltage pocv of the current energy storage device may be obtained first, and the energy storage value (electric quantity, calibration electric quantity) povc _ soc corresponding to the voltage povc may be calculated according to an algorithm. The last power amount last _ soc when shutdown was obtained, and povc _ soc and last _ soc are compared. And when the povc _ soc meets the high-low power, displaying the povc _ soc as a display power on a display screen of the vehicle-mounted terminal. When povc _ soc does not satisfy the high-low power amount, last _ soc is taken as the display power amount, as shown in fig. 9. Povc _ soc is followed in charging and discharging until povc _ soc equals last _ soc. For example, when last _ soc is smaller than povc _ soc, the rate of change of the increase in the display charge amount is fast during charging. When last _ soc is larger than povc _ soc, the rising change speed of the display power is slower in the charging process, and the normal change is recovered until the calibration power is equal to the display power.

In some embodiments, in the charging method of the vehicle-mounted terminal provided in the embodiment of the present application, when the current remaining power of the energy storage device of the vehicle-mounted terminal is obtained, the method may further be implemented in the following manner: and acquiring the current storage value of the energy storage device of the vehicle-mounted terminal, and determining the maximum storage value of the energy storage device according to the current environment temperature. And further, taking the ratio of the current storage value to the maximum storage value as the current residual capacity of the energy storage device. Specifically, as shown in fig. 10, the method includes the following steps:

s1, acquiring the voltage pocv of the energy storage device.

And S2, calculating an energy storage value povc _ soc corresponding to the voltage pocv of the energy storage device.

And S3, determining the maximum storage value of the energy storage device according to the current environment temperature, and taking the ratio of the current storage value to the maximum storage value as the current residual capacity of the energy storage device.

In some embodiments, the energy storage value (storage capacity) of the energy storage device is temperature-dependent, and the energy storage value has a positive correlation with the temperature. Normally, the energy storage value of the energy storage device is calculated according to the standard temperature of 25 ℃. When the temperature is reduced by 1 degree centigrade, the storage capacity of the energy storage device is reduced by about 0.8%. For example, the maximum energy storage value of an energy storage device at a standard temperature is 3000 milliamps, and when the temperature is reduced to 10 degrees celsius, the maximum energy storage value of the energy storage device at that temperature becomes 2640 milliamps. When the temperature rises to 35 degrees celsius, the maximum energy storage value of the energy storage device at that temperature becomes 3240 milliamps.

Based on this, the ratio of the current storage value to the maximum storage value can be used as the current remaining capacity of the energy storage device according to the current ambient temperature. For example, the energy storage value of the energy storage device is 1620 milliamperes, the current ambient temperature is 35 degrees celsius, the maximum energy storage value of the energy storage device at the temperature is 3240 milliamperes, the ratio of the current energy storage value to the maximum energy storage value is 50%, and 50% of the current remaining power of the energy storage device is used as the current remaining power of the energy storage device.

And S4, displaying the current residual electric quantity on a display screen of the vehicle-mounted terminal as the display electric quantity.

Based on the scheme, the energy storage value of the energy storage device is calibrated according to the temperature after the vehicle-mounted terminal is started, and the accuracy of electric quantity display is guaranteed.

In some embodiments, the remaining charge of the energy storage device is monitored during charging of the energy storage device via the first power supply interface. When it is monitored that the remaining capacity of the energy storage device is greater than or equal to the second set threshold, the energy storage device is stopped to be charged through the first power supply interface, as shown in fig. 11. Wherein the second set threshold is greater than the first set threshold. The second setting threshold can be set according to the requirements of users. In some scenarios, the second set threshold may be an amount of power. And when the residual capacity is greater than or equal to the second set threshold, stopping charging the energy storage device through the first power supply interface. For example, the user sets the second set threshold to 2500 milliamps. And when the residual electric quantity of the energy storage device is detected to be 2500 milliamperes and is equal to a first set threshold, stopping charging the energy storage device through the first power supply interface. In other scenarios, the second set threshold may be a percentage of the remaining power. The percentage of the current remaining capacity can be obtained from the detected remaining capacity and the total energy storage value of the energy storage device, and then the percentage of the current remaining capacity is compared with a second set threshold value. And when the percentage of the residual capacity is greater than or equal to a second set threshold value, stopping charging the energy storage device. For example, the second set threshold is 80%. When the remaining capacity is 2400 milliamperes and the total storage capacity of the energy storage device is 3000 milliamperes, the percentage of the current remaining capacity is 80%, and is equal to the second set threshold. Therefore, the energy storage device stops being charged via the first power supply interface.

In some embodiments, when it is detected that the first power supply interface for supplying power to the vehicle-mounted terminal by the vehicle is converted from the power supply state to the power supply stop state, the vehicle-mounted terminal is prohibited from being powered off. In some scenes, when the power supply interface for supplying power to the vehicle-mounted terminal by the vehicle is detected to be switched from the power supply state to the power supply stop state, the vehicle-mounted terminal cannot be immediately shut down, and a prompt window can be displayed on a display screen of the vehicle-mounted terminal. As shown in fig. 12, the prompt window is used for prompting the user whether to continue to use the vehicle-mounted terminal, the prompt window further includes two controls, and the user can further select whether to continue to use the vehicle-mounted terminal by clicking the controls.

In some scenarios, the in-vehicle terminal is kept on in response to a user selecting an operation to continue using the in-vehicle terminal. For example, as shown in fig. 13, the user clicks a control of "continue to use" on the display screen of the in-vehicle terminal, and in response to the clicking operation of the user, the in-vehicle terminal is kept opened for the user to continue to use.

In other scenarios, the in-vehicle terminal is turned off in response to a user selecting an operation that the in-vehicle terminal is no longer in use. For example, as shown in fig. 14, the user clicks a "power off" control on the display screen of the in-vehicle terminal, and the in-vehicle terminal is turned off in response to the clicking operation of the user. In some embodiments, the in-vehicle terminal is turned off when an operation of the user selecting whether to use the in-vehicle terminal is not detected within a set time period. The set time period may be set according to a requirement of a user, for example, 10 seconds, 20 seconds, and the like, which is not specifically limited in this application. As an example, if the user does not select whether to continue using the in-vehicle terminal within 10 seconds after the prompt window is displayed on the display screen, the in-vehicle terminal is directly turned off.

In some embodiments, when it is detected that the first power supply interface is in a power supply stop state and the vehicle-mounted terminal is turned on, the current remaining capacity of the energy storage device is monitored. And when the current residual capacity of the energy storage assembly is smaller than a third set threshold value, closing the vehicle-mounted terminal. As shown in fig. 15, the specific process is as follows:

s11, after the vehicle is flamed out, the state of the first power supply interface for supplying power to the vehicle-mounted terminal by the vehicle can be detected to be a power supply stopping state.

And S12, determining whether the user selects to continue using the vehicle-mounted terminal.

And S13, detecting the current residual electric quantity of the energy storage device of the vehicle-mounted terminal after the first power supply interface is in the state of stopping power supply and the user selects to continue to use the vehicle-mounted terminal.

And S14, when the current residual capacity of the energy storage device is smaller than a third set threshold value, closing the vehicle-mounted terminal.

The third setting threshold may be set according to a user requirement, which is not specifically limited in this application. As an example, the third set threshold is 20%. And when the current residual capacity of the energy storage device is lower than 20%, the vehicle-mounted terminal is closed.

In some scenarios, the step S14 may be replaced by the following steps, as shown in fig. 16:

and S140, when the current residual capacity of the energy storage device is smaller than a third set threshold value, displaying a reminding popup window on a display screen of the vehicle-mounted terminal.

Wherein, remind the popup and be used for reminding the user that the electric quantity is low, whether choose to continue to use. As an example, when the current electric quantity of the energy storage device is 19% and the third set threshold is 20%, as shown in fig. 17, a prompt popup window displays "low electric quantity and whether to continue to use", and two controls are "continue to use" and "turn off", respectively.

And S141, responding to the operation of the user for selecting the continuous use, and keeping the vehicle-mounted terminal on.

As shown in fig. 18, when the user clicks "continue to use", the in-vehicle terminal is not turned off.

And S142, in response to the user selecting the shutdown operation or not detecting whether the user selects the operation of continuing to use within the set time length, closing the vehicle-mounted terminal.

As shown in fig. 19, when the user clicks "power off", the in-vehicle terminal is turned off. Or, when the operation that whether the user selects to use the vehicle-mounted terminal is not detected within the set time length, the vehicle-mounted terminal is closed. The set time period may be set according to a requirement of a user, for example, 10 seconds, 20 seconds, and the like, which is not specifically limited in this application. As an example, if the user does not select whether to continue using the in-vehicle terminal within 10 seconds after the prompt window is displayed on the display screen, the in-vehicle terminal is directly turned off.

Based on the scheme, after the vehicle is flamed out, when the vehicle cannot supply power to the vehicle-mounted terminal through the first power supply interface, the option of continuous use can be provided for the user through the prompt popup window. In addition, the problem of electric quantity consumption caused by forgetting to shut down the vehicle after the vehicle is shut down can be avoided by setting automatic shutdown within set time.

In some embodiments, the vehicle terminal supports unloading from the vehicle. When the second power supply interface of the vehicle-mounted terminal is detected to be in a power supply state, the energy storage device of the vehicle-mounted terminal can be charged through the second power supply interface. The second power supply interface is an interface for charging an energy storage device of the vehicle-mounted terminal through a power supply or commercial power, and is different from the first power supply interface. As an example, when the in-vehicle terminal is charged through the first power supply interface, the method may be referred to as a micro-cycle charging mode. And when the vehicle-mounted terminal detects that the power supply interface is the first power supply interface, entering a micro-cycle charging mode. And when the vehicle-mounted terminal detects that the power supply interface is the second power supply interface, the vehicle-mounted terminal can be charged according to the normal charging mode through the second power supply interface. When the in-vehicle terminal is mounted on the vehicle, the energy storage device is charged in the micro-cycle charging mode through the first power supply interface, as shown in fig. 20.

Through the scheme, the vehicle-mounted terminal is charged according to the micro-cycle charging mode when being mounted on the vehicle, and can be charged according to the normal charging mode through other power supply interfaces when being dismounted from the vehicle.
