[0002] With the increasing popularity of electric vehicles, people have put forward multi-level requirements for electric vehicles, including long driving range, outstanding driving performance, etc., and these requirements are directly related to the power battery of electric vehicles: on the one hand, in order to achieve long driving range, the power battery is required to reserve a higher energy; on the other hand, in order to make the vehicle have outstanding driving performance, the power battery is required to provide high power output.

The optional embodiments of the present application are described in detail as follows, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0035] Please refer to the attached Figure 1-5 The method for displaying the battery state of charge, the electronic device, and the vehicle according to the embodiment of the present invention are described. The method for displaying the battery state of charge 100 according to the embodiment of the present invention is used for at least two battery packs of the same vehicle. The at least two battery packs may be battery packs with the same cell specifications and the same number of cells, or the at least two battery packs may be battery packs with different cell specifications and different numbers of cells. Figure 1 , Figure 1 A schematic flow chart of a method 100 for displaying a battery state of charge according to an embodiment of the present invention is shown. The method comprises:

[0036] In step S110, determining the working state of each battery pack of at least two battery packs;

[0037] In step S120, a first battery pack and a second battery pack among the at least two battery packs are determined according to the working state, wherein the first battery pack is a battery pack whose working state is a normal state, and the second battery pack is a battery pack whose working state is an abnormal state;

[0038] In step S130, a first energy state of the first battery pack and a second energy state of the second battery pack are determined respectively;

[0039] In step S140, a first state of charge is determined according to the first energy state, and a second state of charge is determined according to the second energy state;

[0040] In step S150 , the first state of charge and / or the second state of charge is displayed.

[0041] The method 100 for displaying the battery charge state of the embodiment of the present invention displays the charge state of the battery pack in normal state and abnormal state respectively, so that the user can clearly understand the remaining battery capacity and take corresponding countermeasures.

[0042] Specifically, the working state of each battery pack in at least two battery packs is first determined. Among them, the possible working states of the battery pack include normal state and abnormal state. The normal state means that the battery pack can discharge externally, and the abnormal state means that the battery pack cannot discharge externally, that is, when the battery pack works normally, the remaining energy of the battery pack can be output for energy, and when the battery pack works abnormally, the remaining energy of the battery pack cannot be output. By detecting whether each battery pack can discharge normally, the working state of each battery pack can be divided into normal state or abnormal state.

[0043] After determining the working state of each of the at least two battery packs, determine the first battery pack and the second battery pack of the at least two battery packs according to the determined working state. The working state of the first battery pack is a normal state, and the working state of the second battery pack is an abnormal state. That is to say, in this step, the battery pack with a normal working state is defined as the first battery pack, the first battery pack is a battery pack with a normal working state, the first battery pack may include one or more battery packs and is not limited to one battery pack, the battery pack with an abnormal working state is defined as the second battery pack, the second battery pack is a battery pack with an abnormal working state, the second battery pack may also include one or more battery packs and is not limited to one battery pack.

[0044] The division of battery packs may include the following three situations: in the first situation, the working state of each battery pack in at least two battery packs is normal, and the at least two battery packs are first battery packs; in the second situation, the working state of at least one battery pack in at least two battery packs is normal, and the working state of at least one other battery pack is abnormal, and the at least two battery packs include a first battery pack and a second battery pack; in the third situation, the working state of each battery pack in at least two battery packs is abnormal, and the at least two battery packs are second battery packs.

[0045] Next, the first energy state of the first battery pack and the second energy state of the second battery pack are determined respectively, and then the first state of charge is determined according to the first energy state, and the second state of charge is determined according to the second energy state. It should be noted that when the number of first battery packs is at least two, the first state of charge is the total state of charge of the at least two first battery packs; similarly, when the number of second battery packs is at least two, the second state of charge is the total state of charge of the at least two second battery packs.

[0046] When determining the state of charge of a battery pack, if the cell specifications or the number of cells of different battery packs are inconsistent, if the individual states of charge of multiple battery packs are integrated into the state of charge displayed to the user by means of weighted coefficients, due to the difference in weighted coefficients, the state of charge displayed to the user in this manner is prone to jump during use, which is not conducive to the user's prediction of the drivable distance of the entire vehicle. In order to avoid the above problems, in one embodiment of the present invention, the state of charge of the battery pack is determined according to its SOE (State of Energy), and the energy state represents the percentage of remaining energy in the battery pack. The remaining energy determines the remaining driving range of the vehicle. The remaining mileage can be directly represented by accumulating the remaining energy of all battery packs. Therefore, when calculating the SOE of multiple battery packs, there is no need to perform weighting, which can avoid the influence of the weighted coefficient on the final result.

[0047] Displaying the first state of charge and / or the second state of charge includes: displaying the first state of charge and the second state of charge in different display modes.

[0048] Exemplarily, different display modes include at least one of the following: different colors, different sizes, and different fonts. For example, the first state of charge may be displayed in a larger font size, and the second state of charge may be displayed in a smaller font size; the first state of charge may be displayed in green, and the second state of charge may be displayed in gray or red, etc.

[0049] When calculating the state of charge according to the energy state, a first energy state of the first battery pack and a second energy state of the second battery pack are determined respectively; a first state of charge is determined according to the first energy state, and a second state of charge is determined according to the second energy state.

[0050] The first energy state is obtained according to the ratio of the remaining energy of the first battery pack to the total nominal energy of at least two battery packs, and the second energy state is obtained according to the ratio of the remaining energy of the second battery pack to the total nominal energy of at least two battery packs. Figure 2As shown, it is assumed that multiple battery packs form a battery group, and the battery pack specifically includes battery pack A1, battery pack A2, ..., battery pack AN, wherein the nominal energy of battery pack A1 is Y1, and the remaining energy is X1, the nominal energy of battery pack A2 is Y2, and the remaining energy is X2, ..., the nominal energy of battery pack AN is YN, and the remaining energy is XN. X1-XN represents the remaining energy (Wh) of each battery pack, which can be output when the battery pack is in normal working condition, and cannot be output when the battery pack is in abnormal working condition; Y1-YN represents the nominal energy (Wh) of each battery pack, which can be adjusted based on factors such as ambient temperature and battery attenuation. In actual applications, there may be the following three working conditions:

[0051] 1) Working condition 1: when the working status of all battery packs is normal, that is, all battery packs are first battery packs, the value of the second energy state SOE2 is 0, and the calculation formula of the first energy state SOE1 is:

[0052]

[0053] 2) Working condition 2: when the working state of some battery packs is normal and the working state of some battery packs is abnormal, assuming that the first battery pack in normal state is numbered A1 and the second battery pack in abnormal state is numbered A2 to AN, the calculation formulas of the first energy state SOE1 and the second energy state SOE2 are respectively:

[0054]

[0055] 3) Working condition 3: when the working status of all battery packs is abnormal, that is, all battery packs are second battery packs, the value of the first energy state SOE1 is 0, and the calculation formula of the second energy state SOE2 is:

[0056]

[0057] After calculating the energy state under the above working conditions, the first energy state SOE1 is converted into the first state of charge SOC1, and the second energy state SOE2 is converted into the second state of charge SOC2 according to the mapping relationship between the energy state and the state of charge. For example, SOE1 can be mapped to SOC1, and SOE2 can be mapped to SOC2 according to a preset mapping relationship, that is:

[0058] f(SOE1)→SOC1

[0059] f(SOE2)→SOC2

[0060] After the first state of charge and the second state of charge are obtained, the first state of charge and / or the second state of charge are displayed.

[0061] The first state of charge indicates the available state of charge of the vehicle, and the second state of charge indicates the unavailable state of charge of the vehicle. Displaying the first state of charge and the second state of charge separately helps the user to clearly understand the remaining capacity of the battery, thereby making more accurate driving decisions.

[0062] Exemplarily, displaying the first state of charge and / or the second state of charge includes: when the at least two battery packs include at least one first battery pack and at least one second battery pack, displaying the first state of charge and the second state of charge simultaneously. Figure 3 As shown, when at least two battery packs include at least one first battery pack and at least one second battery pack, that is, when there are battery packs in normal state and abnormal state in the battery packs, the first state of charge and the second state of charge are not zero. At this time, the first state of charge (40%) and the second state of charge (10%) are displayed simultaneously, wherein 40% and 10% are just examples of a situation where the first state of charge is 40% and the second state of charge is 10%. When there are battery packs in normal state and abnormal state in the battery packs, the first state of charge and the second state of charge may also display other values, such as 50% and 20%, respectively. Exemplarily, displaying the first state of charge and / or the second state of charge also includes: when at least two battery packs are the second battery packs, displaying the first state of charge and the second state of charge simultaneously. As Figure 3 As shown, when at least two battery packs are the second battery packs, that is, when only the battery pack in an abnormal state exists among the battery packs, the value of the first state of charge is zero. At this time, the first state of charge (0%) and the second state of charge (50%) can be displayed simultaneously to remind the user that the available state of charge of the vehicle is zero and to take timely countermeasures. When the battery packs are all in an abnormal state, the first state of charge is usually represented by 0%, and 50% is just an example of a situation where the second state of charge is 50%. Other values, such as 60%, can also be displayed.

[0063] Exemplarily, displaying the first state of charge and / or the second state of charge further includes: when the at least two battery packs are both the first battery packs, only displaying the first state of charge. Figure 3 As shown, when at least two battery packs are the first battery packs, that is, only the battery pack in normal state exists in the battery packs, the value of the second state of charge is zero, and the user does not need to pay extra attention to this state of charge, so only the first state of charge (50%) can be displayed, and 50% is just an example of a situation where the SOC is 50%. When all the battery packs are normal, other values, such as 60%, can also be displayed. Optionally, the first state of charge and the second state of charge can also be displayed at the same time, that is, the value of the second state of charge is displayed as zero.

[0064] In order to facilitate users to distinguish the state of charge of a normal battery pack from the state of charge of an abnormal battery pack, the first state of charge and the second state of charge may be displayed in different display modes. The different display modes include different colors, different sizes, and different fonts. For example, the first state of charge may be displayed in a larger font size, and the second state of charge may be displayed in a smaller font size; the first state of charge may be displayed in green, and the second state of charge may be displayed in gray or red, etc.

[0065] Exemplarily, when at least two battery packs include at least one second battery pack, battery pack failure prompt information is displayed. That is, when there is a battery pack in an abnormal state among the at least two battery packs, battery pack failure prompt information may also be displayed to remind the user to pay attention to the abnormal condition. The battery pack failure prompt information may include but is not limited to text prompts, graphic prompts, symbol prompts, etc., and may specifically include a string like "battery pack has a fault" or an abnormal icon, or may further include detailed information such as the number of battery packs in an abnormal state.

[0066] In summary, the battery state of charge display method 100 of the embodiment of the present invention obtains different energy states for battery packs in different working states, and further obtains technical means of different state of charge, so that the state of charge of battery packs in normal state and abnormal state can be displayed separately, which is convenient for users to clearly understand the remaining battery capacity, so that the SOC display accuracy is high.

The vehicle 500 further comprises a display 510, and the electronic device 400 is connected to the display 510, and is used to control the display 510 to display the first state of charge and / or the second state of charge after obtaining the first state of charge and the second state of charge.
