Based on the above hardware structure, an embodiment of the charging time determination method of the present invention is provided.
Referring to fig. 2, fig. 2 is a schematic flowchart of a charging time determination method according to a first embodiment of the present invention, and the charging time determination method according to the first embodiment of the present invention is provided.
In a first embodiment, the charging time determination method includes the steps of:
step S10: and acquiring the initial electric quantity and the final electric quantity of the battery of the vehicle in each charging process in a preset period.
It should be understood that the execution subject of the present embodiment is a vehicle charging control apparatus that includes an information acquisition module, an information processing module, and a display module. The information acquisition module is used for acquiring the state information of the vehicle battery; the information processing module is used for processing the acquired state information to calculate the residual charging time; the display module is used for displaying the residual charging time.
It should be noted that the preset period is a preset charging time correction period, and the preset period may be one month. The initial charge of the battery refers to the charge of the vehicle battery before the battery is charged, and the initial charge of the battery is not less than ten percent of the capacity of the battery in a specific charging process. The battery-termination electric quantity refers to an electric quantity contained in the vehicle battery after the charging process is performed, and in a specific vehicle battery charging process, the battery-termination electric quantity is a vehicle battery capacity.
It is understood that the charging time adjustment period needs to be preset before the initial charge and the final charge of the vehicle battery are acquired. In a specific implementation process, the initial battery capacity and the terminal battery capacity of all charging processes in a complete cycle can be queried through the storage medium, and are also obtained in a cloud data synchronization manner, which is not specifically limited herein.
Step S20: and determining the charging capacity of each charging process according to the initial battery capacity and the final battery capacity.
It should be noted that the charge amount of each charging process is a set of the charge amounts of the vehicle battery in all charging processes. The charge amount in the set of charge amounts to the vehicle battery corresponds to the charge process one by one.
It can be understood that, in the case where the initial charge amount and the final charge amount of the battery in a certain charging process are known, the charge amount in the charging process can be obtained through simple mathematical operations. And sequentially calculating the charging quantity of all the charging processes to further obtain the charging quantity of each charging process.
Step S30: and comparing the charging quantity of each charging process with a preset charging quantity threshold value to obtain the effective charging process in the preset period.
It should be noted that the preset charge threshold is a preset charge threshold, and the preset charge threshold is used for distinguishing an effective charging process from an ineffective charging process. The effective charging process refers to a charging process in which the charging amount of the vehicle battery exceeds a certain threshold in the charging process, for example, in a certain charging process, due to the driving time of a driver and passengers, the charging amount is only enough to reach a destination, the charging amount is relatively small, and may be ten percent or twenty percent, and the charging process cannot reflect the actual charging condition of the vehicle battery, and the charging process is determined to be an ineffective charging process.
It can be understood that, in the case that the vehicle battery charging amount in the charging process is known, the vehicle battery charging amount in the charging process is compared with the preset charging amount threshold, and whether the vehicle battery charging amount in the charging process is greater than the preset charging amount threshold is determined. If the judgment result is yes, the charging process is determined to be an effective charging process, otherwise, the charging process is determined to be an ineffective charging process. And comparing and judging the charging quantity of the vehicle battery in all charging processes in the preset period to obtain all effective charging processes in the preset period.
Step S40: and calculating a charging time correction coefficient according to the charging quantity corresponding to the effective charging process.
The charging time correction coefficient is a coefficient for correcting the accuracy of the remaining charging time. This coefficient reflects the change in battery parameters over time for the vehicle battery. The charge amount corresponding to the effective charging process is the amount of electric energy actually charged to the vehicle battery in the effective charging process.
It can be understood that the charge time correction coefficient is calculated based on the charge amount corresponding to the effective charging process, that is, the amount of electric charge actually charged in the vehicle battery and the theoretical charge amount. The theoretical charge amount may be determined based on the battery capacity and the initial battery charge amount. For example, the effective charging process corresponds to a charging amount of eighty percent, the initial battery amount of ten percent, i.e., the theoretical charging amount of ninety percent, and the charging time correction factor is eight-ninth.
Step S50: and determining the residual charging time of the battery according to the charging time correction coefficient and the preset standard charging time.
The preset standard charging time is the standard charging time after the previous cycle is corrected. In the case of the charging current determination, the standard charging time is proportional to the charge amount of the vehicle battery. The remaining charge time is the time between which the driver and the passenger can directly read that the battery is fully charged.
It can be understood that, when the charging time correction coefficient in the preset period and the preset standard charging time in the previous period are determined, the current standard charging time can be obtained through calculation, and then the remaining charging time of the vehicle battery is determined.
The method comprises the steps of obtaining initial battery electric quantity and terminal battery electric quantity of a vehicle battery in each charging process in a preset period, further determining charging electric quantity of each charging process, then comparing the charging electric quantity of each charging process with a preset charging electric quantity threshold value to obtain an effective charging process, then calculating a charging time correction coefficient according to the charging electric quantity corresponding to the effective charging process, and finally determining the remaining charging time of the battery by using the charging time correction coefficient and preset standard charging time. In the prior art, most of the determination of the charging time of the automobile battery is calculated according to the real-time capacity, but the charging time is determined inaccurately due to the fact that parameters of the automobile battery change along with the change of the time, and the effective charging process is determined by determining the charging quantity, the charging time correction coefficient is calculated, and further the remaining charging time of the battery is calculated accurately.
Referring to fig. 3, fig. 3 is a flowchart illustrating a charging time determination method according to a second embodiment of the present invention, and the charging time determination method according to the second embodiment of the present invention is proposed based on the first embodiment shown in fig. 2.
In the second embodiment, the step S40 includes:
step S401: and traversing the effective charging process to obtain the current effective charging process.
It should be noted that traversal is a non-repeated selection process for all elements in the range, and the selected elements are not put back in the range. In this embodiment, the current effective charging process is randomly selected from all the effective charging processes, and after the subsequent steps, the current charging process is updated.
It can be understood that the effective charging process is a set including all effective charging processes, and in this embodiment, the charging time correction coefficients corresponding to each effective charging process need to be calculated one by one, and the effective charging processes in the set of effective charging processes need to be traversed to obtain the current effective charging process.
Step S4021': and acquiring the initial electric quantity of the battery corresponding to the current effective charging process.
It should be noted that, in step S10, the initial battery power in each charging process in the preset period is obtained, and the initial battery power corresponding to the current effective charging process is extracted from the obtained initial battery power set. In this embodiment, the initial battery power corresponding to the current effective charging process may be obtained in a manner of instruction obtaining from the initial battery power set stored in the memory card or the cloud.
Step S4022': and calculating the theoretical charging quantity of the current effective charging process according to the initial battery quantity corresponding to the current effective charging process.
It should be noted that the initial battery capacity corresponding to the currently active charging process is the battery capacity of the vehicle battery before the currently active charging process is started. The theoretical charge amount is an amount of electricity that the current battery can theoretically be charged, and the theoretical charge amount is determined based on the battery capacity corrected at the previous time and the current initial battery charge amount.
It can be understood that the theoretical charge capacity of the current vehicle battery can be clearly obtained by knowing the initial charge capacity of the battery corresponding to the current effective charging process and the previously corrected battery capacity.
Step S402': and calculating a single charging time correction coefficient according to the charging quantity corresponding to the current effective charging process and the theoretical charging quantity.
It should be noted that the single charge time correction coefficient is a charge time correction coefficient for a certain effective charge process. And obtaining a charging time correction coefficient corresponding to the current effective charging process as a single charging time correction coefficient according to the charging amount corresponding to the current effective charging process and the theoretical charging amount corresponding to the current effective charging process.
Step S403: at the end of the traversal, all the single charge time correction coefficients are obtained.
It should be noted that, at the end of the traversal, all the effective charging processes are subjected to the calculation of the single charging time correction coefficient, so as to obtain all the single charging time correction coefficients. And extracting all the single charging time correction coefficients, and carrying out the next step operation.
Step S404: and calculating the average value of all the single charging time correction coefficients, and taking the calculation result as the charging time correction coefficient.
It should be noted that, in the present embodiment, the charging time correction coefficient is an accurate time correction coefficient calculated for all effective charging processes. And calculating the average value of all the obtained single charging time correction coefficients to obtain an average charging time correction coefficient, and taking the calculated average time correction coefficient as the charging time correction coefficient.
The method comprises the steps of obtaining initial battery electric quantity and terminal battery electric quantity of a vehicle battery in each charging process in a preset period, further determining charging electric quantity of each charging process, then comparing the charging electric quantity of each charging process with a preset charging electric quantity threshold value to obtain an effective charging process, then calculating a charging time correction coefficient according to the charging electric quantity corresponding to the effective charging process, and finally determining the remaining charging time of the battery by using the charging time correction coefficient and preset standard charging time. In the prior art, most of the determination of the charging time of the automobile battery is calculated according to the real-time capacity, but the charging time is determined inaccurately due to the fact that parameters of the automobile battery change along with the change of the time, and the effective charging process is determined by determining the charging quantity, the charging time correction coefficient is calculated, and further the remaining charging time of the battery is calculated accurately.
Referring to fig. 4, fig. 4 is a flowchart illustrating a charging time determination method according to a third embodiment of the present invention, and the charging time determination method according to the third embodiment of the present invention is proposed based on the first embodiment shown in fig. 2.
In the third embodiment, the step S50 includes:
step S501: and determining the current standard charging time according to the charging time correction coefficient and the preset standard charging time.
It should be noted that the current standard charging time is a charging time required for the vehicle battery capacity to be fully charged from zero in the current effective charging process, and the preset standard time is a standard charging time corrected in the previous cycle, that is, a standard charging time to be corrected.
It can be understood that, knowing the standard charging time to be corrected and the charging time correction coefficient, the steamer charging time correction coefficient corrects the standard charging time to be corrected, and the current standard charging time can be obtained.
Step S502: the method comprises the steps of obtaining the current initial electric quantity of a battery, and determining the current charging electric quantity of the battery according to the current initial electric quantity of the battery.
It should be noted that the current charge amount is an amount of electricity that actually needs to be charged in the vehicle battery. And correcting the preset standard time according to the current time correction coefficient, so that the capacity of the battery can be corrected to obtain the current capacity of the battery. The current charge amount may be determined according to the current capacity of the battery and the current initial charge amount.
Step S5031: and acquiring the current vehicle current consumption state.
The vehicle current consumption state is a state in which current is consumed in the vehicle interior. Devices such as electric drive motors, air conditioners, etc. in the vehicle consume electric current in the vehicle. In the actual charging process, the charging current firstly satisfies the current consumption in the vehicle, and the vehicle battery is charged under the condition that the current consumption in the vehicle is satisfied.
Step S50321: and obtaining the current consumption current value according to the current vehicle current consumption state.
It should be noted that the current vehicle consumption current value is a current value consumed by the current vehicle internal electrical appliance. And determining the current value of each electrical appliance according to the current consumption state in the vehicle, and summing the current values of all electrical appliances in the vehicle to obtain the current consumption current value of the vehicle.
Step S50322: and obtaining the current standard current value according to the current standard charging time.
It should be noted that the current standard current value is a current value supplied from a vehicle battery charger. In the case of the vehicle battery capacity determination, the current standard charging time of the vehicle is inversely proportional to the current standard current value. In the implementation process, the current standard current value can be determined by detecting the power of the charger, and in the embodiment, the current standard current value can be determined according to the capacity of the vehicle battery and the current standard charging time.
Step S50323: and acquiring an actual charging current value according to the current standard current value and the current consumption current value.
The actual charging current value is a current value of the battery charge amount. In the case where the current standard current value and the current consumption current value are known, the actual charging current value can be obtained by calculation. The current value supplied by the external power supply is the current value charged in the vehicle battery by canceling the current value consumed inside the vehicle.
Step S503': and determining the residual charging time according to the actual charging current value and the current charging amount of the battery.
It should be noted that the remaining charging time can be determined by calculation according to the actual charging current value and the current charging amount of the vehicle battery, for example, in the charging process of the vehicle battery, the actual charging current value can charge twenty percent of the battery capacity per hour, the vehicle battery needs to be charged eighty percent of the battery capacity currently, and obviously, the remaining charging time is four hours.
Step S504: and acquiring actual charging capacity according to the residual charging time and the actual charging current.
It should be noted that the actual charge amount is an amount of electricity for charging the battery from the initial charge amount of the battery to the full state of the battery. And calculating to obtain the actual charging capacity according to the residual charging time and the actual charging current.
Step S505: and correcting the battery capacity of the vehicle battery according to the actual charging capacity and the current initial electric quantity of the battery.
The correction of the battery charging time is performed based on the correction of the battery capacity. The battery capacity correction is that the battery capacity is changed after long-time change, and the calibrated battery capacity is corrected based on the current battery capacity.
It is understood that the actual charge amount is summed with the current initial charge amount, and the resulting sum is used as the corrected battery capacity.
The method comprises the steps of obtaining initial battery electric quantity and terminal battery electric quantity of a vehicle battery in each charging process in a preset period, further determining charging electric quantity of each charging process, then comparing the charging electric quantity of each charging process with a preset charging electric quantity threshold value to obtain an effective charging process, then calculating a charging time correction coefficient according to the charging electric quantity corresponding to the effective charging process, and finally determining the remaining charging time of the battery by using the charging time correction coefficient and preset standard charging time. In the prior art, most of the determination of the charging time of the automobile battery is calculated according to the real-time capacity, but the charging time is determined inaccurately due to the fact that parameters of the automobile battery change along with the change of the time, and the effective charging process is determined by determining the charging quantity, the charging time correction coefficient is calculated, and further the remaining charging time of the battery is calculated accurately.
Furthermore, an embodiment of the present invention further provides a storage medium, on which a charging time determination program is stored, which when executed by a processor implements the steps of the charging time determination method as described above.
