Description

Method, device and storage medium for determining remaining charging time of vehicle

Technical Field

The present invention relates to the field of vehicle technology, and in particular to a method, device and storage medium for determining the remaining charging time of a vehicle.

Background Art

At present, traditional fuel vehicles are gradually being replaced by new energy vehicles. Charging time, as an important technical indicator of new energy vehicles, is directly related to the user's driving experience and travel flexibility. For example, when the charging time is short, it can improve user satisfaction, and when the charging time is long, it will limit the user's travel range and schedule. Therefore, accurate control of charging time can further improve the reliability of new energy vehicles.

However, the current method of calculating the charging time is mainly based on the current state of charge (SOC) of the vehicle combined with the ampere-hour integration method, that is, the battery charging time is obtained by superimposing the time periods in each constant current interval. This method of calculating the vehicle charging time has poor accuracy in estimating the remaining charging time of the vehicle, thereby reducing the reliability of the vehicle and seriously affecting the user experience.

To address the above-mentioned problems, no effective solution has been proposed yet.

FIG. 1 is a flow chart of a method for determining the remaining charging time of a vehicle according to one embodiment of the present invention. As shown in FIG. 1 , the method includes the following steps:

Step S11, in response to the target vehicle entering a charging mode, acquiring target voltage information and first voltage information, wherein the target voltage information represents a voltage value corresponding to the target vehicle at the end of charging, and the first voltage information represents a voltage value of the target vehicle at the current moment;

In step S11, the target voltage information is used to represent the battery voltage value corresponding to the SOC when the target vehicle ends charging, which is recorded as V _preset . For example, when the SOC of the target vehicle reaches 90%, the target vehicle stops charging, and the target voltage information is the battery voltage corresponding to the SOC of 90%.

The first voltage information is used to represent the battery voltage value corresponding to the current SOC of the target vehicle, which is recorded as V _now .

Specifically, the Battery Management System (BMS) is responsible for monitoring and managing the battery pack, and is usually connected to multiple Cell Monitoring Units (CMUs). Each CMU monitors parameters such as voltage, current, and temperature of a group of cells. The CMU obtains real-time data of the cells through sensors and sends the real-time data of the cells to the BMS for processing. The BMS receives voltage data from each cell through the CMU. In order to obtain accurate voltage values, high-precision voltage sensors are used, and the effect of temperature on voltage measurement is considered. After receiving the voltage data of the cell, the BMS verifies the integrity and accuracy of the data to ensure the reliability of the data. Then, the BMS traverses the voltage data of all cells to find the maximum voltage value at the current moment, recorded as V _now . For example, the SOC of the target vehicle at the current moment is 40%, and the maximum voltage value at the current moment is 3.7V, then V _now is 3.7V.

Step S12, determining a correction coefficient using the target voltage information and the first voltage information;

Specifically, V _preset and V _now are used to determine the voltage change rate of the target vehicle during the charging process, which is recorded as α. The difference between the target power and the current power of the target vehicle during the charging process is corrected using the correction coefficient 1-α, so that the remaining SOC of the target vehicle during the charging process can be more accurately calculated.

Step S13, determining the remaining charging time of the target vehicle based on the correction coefficient.

In step S13, the remaining charging time is used to represent the remaining charging time of the target vehicle until the charging is completed, and is recorded as t _rest .

Specifically, the t _rest of the target vehicle is determined according to 1-α, and t _rest is sent to the charging pile or the user's smart terminal. Thus, the user can immediately obtain the accurate t _rest of the power battery when the charging pile starts charging, thereby improving the user experience.

Based on the above steps S11 to S13, in response to the target vehicle entering the charging mode, the target voltage information and the first voltage information are obtained, the correction coefficient is determined using the target voltage information and the first voltage information, and finally the remaining charging time of the target vehicle is determined based on the correction coefficient, thereby achieving the purpose of quickly and accurately estimating the remaining charging time of the vehicle, thereby achieving the technical effect of improving the accuracy of the estimation of the remaining charging time of the vehicle, and further solving the technical problem of low accuracy of the estimation of the remaining charging time of the vehicle in the related art.

Optionally, the method for determining the remaining vehicle charging time further includes:

Step S14, obtaining target power information and first power information, wherein the target power information indicates the power value corresponding to the charging end time of the target vehicle, and the first power information indicates the power value of the target vehicle at the current time;

In step S14, the target power information is used to represent the battery power value corresponding to the target vehicle when charging is completed, which is recorded as SOC _preset . This value is a preset power value, which represents the power level that the target vehicle should reach when fully charged. This value usually comes from the vehicle's battery management system, charging control system or user settings.

The first power information indicates the power value of the target vehicle at the current moment, which is recorded as SOC _now . It reflects the current power state of the target vehicle and changes in real time. This value comes from the BMS of the target vehicle.

Step S15, in response to the first power information being greater than or equal to the target power information, controlling the target vehicle to exit the charging mode.

Specifically, when SOC _now ≥ SOC _preset , the target vehicle is controlled to exit the charging mode, that is, charging is stopped to avoid overcharging the target vehicle.

Based on the above steps S14 to S15, the target power information and the first power information are obtained. In response to the first power information being greater than or equal to the target power information, the target vehicle is controlled to exit the charging mode. By precisely controlling the charging process, it is possible to accurately determine when to stop charging, thereby avoiding overcharging of the battery and increasing the battery life.

Optionally, the method for determining the remaining vehicle charging time further includes:

Step S16, in response to the first voltage information being equal to the target voltage information, determining that the first power information is equal to the target power information.

Specifically, V _now is monitored in real time, and when V _preset =V _now , it is determined that SOC _now =SOC _preset .

Based on the above step S16, in response to the first voltage information being equal to the target voltage information, it is determined that the first power information is equal to the target power information. Based on the first voltage information, the target vehicle can be controlled to exit the charging mode. The change of voltage information is usually more direct and faster than that of power information. According to the voltage information, the target vehicle is controlled to exit the charging mode, thereby improving the response speed of the vehicle control system.

Optionally, in step S12, determining the correction coefficient using the target voltage information and the first voltage information includes:

Step S121, obtaining second voltage information, wherein the second voltage information is historical voltage information;

In step S121, the second voltage information is used to represent the voltage value of the target vehicle at the last moment, which is recorded as V _last .

Step S122, obtaining first voltage difference information based on the first voltage information and the second voltage information;

In step S122 , the first voltage difference information is V _now −V _last .

Step S123, obtaining second voltage difference information based on the target voltage information and the second voltage information;

In step S123 , the second voltage difference information is V _preset −V _last .

Step S124, determining a correction coefficient based on the first voltage difference information and the second voltage difference information.

Specifically, 1-α is determined according to V _now -V _last and V _preset -V _last .

Based on the above steps S121 to S124, the second voltage information is obtained, the first voltage difference information is obtained based on the first voltage information and the second voltage information, and the second voltage difference information is obtained based on the target voltage information and the second voltage information. Finally, the correction coefficient is determined based on the first voltage difference information and the second voltage difference information. The correction coefficient can be dynamically adjusted according to the actual changes in the vehicle voltage information, so as to more accurately reflect the gap between the current charging state and the target charging state of the target vehicle, thereby improving the accuracy of the calculation of the remaining charging time of the target vehicle.

Optionally, in step S124, determining the correction coefficient based on the first voltage difference information and the second voltage difference information includes:

Step S1241, performing a ratio operation on the first voltage difference information and the second voltage difference information to obtain a voltage variation coefficient;

In step S1241, the voltage variation coefficient is used to characterize the voltage variation rate of the target vehicle during the charging process. The specific calculation process is shown in expression (1).

Wherein, V _now represents the first voltage information, V _last represents the second voltage information, and V _preset represents the target voltage information.

Step S1242, determining a correction coefficient based on the voltage variation coefficient.

Specifically, 1-α is determined as a correction coefficient based on α. The correction coefficient 1-α is used to correct the difference between the target power and the current power during the charging process of the target vehicle, so that the remaining SOC of the target vehicle before the end of charging can be more accurately calculated. Since 1-α is calculated based on real-time voltage changes, it can adapt to different charging conditions and battery states. When the charging conditions or battery state change, 1-α will change accordingly, thereby dynamically adjusting the prediction of the remaining charging time.

Based on the above-mentioned step S1241 and step S1242, the first voltage difference information and the second voltage difference information are ratioed to obtain the voltage change coefficient, and the correction coefficient is determined based on the voltage change coefficient. The historical voltage information is taken into consideration, so that the battery management system of the target vehicle can better cope with abnormal situations such as voltage fluctuations and charging interruptions, thereby improving the stability and reliability of the battery management system.

Optionally, in step S13, determining the remaining charging time of the target vehicle based on the correction coefficient includes:

Step S131, obtaining second power information, wherein the second power information indicates a power value corresponding to the second voltage information;

In step S131, the second power information is used to represent the power value corresponding to the target vehicle V _last , which is recorded as SOC _last .

Step S132, determining first power difference information based on the target power information and the second power information;

In step S132, the first power difference information refers to SOC _preset - SOC _last .

Step S133, multiplying the correction coefficient and the first power difference information to obtain third power information;

In step S133, the third power information is used to represent the remaining SOC of the target vehicle before the charging is completed, which is recorded as SOC _rest . The specific calculation process of SOC _rest is shown in expression (2).

SOC _rest = (1-α) (SOC _preset -SOC _last ) (2)

Among them, SOC _rest represents the third power information, 1-α represents the correction coefficient, SOC _preset represents the target power information, and SOC _last represents the second power information.

Specifically, expression (2) is simplified to expression (3).

Among them, SOC _rest represents the third power information, V _now represents the first voltage information, V _last represents the second voltage information, V _preset represents the target voltage information, SOC _preset represents the target power information, and SOC _last represents the second power information.

Step S134, determining the remaining charging time based on the third power information.

Specifically, t _rest of the target vehicle is updated in real time according to SOC _rest .

Based on the above steps S131 to S134, the second power information is obtained, the first power difference information is determined based on the target power information and the second power information, the correction coefficient and the first power difference information are multiplied to obtain the third power information, and the remaining charging time is determined based on the third power information. This can more accurately predict the remaining SOC of the target vehicle before the end of charging, and then calculate a more accurate remaining charging time.

Optionally, in step S134, determining the remaining charging time based on the third power information includes:

Step S1341, obtaining current information and battery capacity information;

In step S1341, the current information is used to represent the requested current of the target vehicle, which is recorded as I _request .

The above battery capacity information is used to characterize the rated capacity of the target vehicle's power battery, denoted as C.

Step S1342, multiplying the battery capacity information and the third power information to obtain a target capacity value;

In step S1342, the target capacity value is used to represent the battery capacity of the target vehicle that needs to be charged before the charging is completed, which is expressed as C×SOC _rest .

Step S1343, determining the remaining charging time based on the ratio of the target capacity value to the current information.

Specifically, the specific calculation process of t _rest is shown in expression (4).

Wherein, t _rest represents the remaining charging time, C represents the battery capacity information, and I _request represents the current information.

Based on the above steps S1341 to S1343, the current information and battery capacity information are obtained, the battery capacity information and the third power information are multiplied to obtain the target capacity value, and the remaining charging time is determined based on the ratio of the target capacity value to the current information, thereby achieving the purpose of quickly and accurately estimating the remaining charging time of the vehicle, and by providing accurate remaining charging time, it can reduce the inconvenience caused to users by long charging time, thereby improving the user experience.

Optionally, the current information is a current value corresponding to the first electrical quantity information.

Specifically, I _request represents a current value corresponding to SOC _now , which is updated in real time according to SOC _now . The BMS can calculate t _rest of the target vehicle more accurately according to the dynamic change of I _request .

FIG2 is a flow chart of another method for determining the remaining time of vehicle charging according to one embodiment of the present invention. As shown in FIG2 , the method mainly includes the following execution steps:
