Description
Technical Field
The present invention relates to the field of electronic devices, and in particular, to a method and an apparatus for determining remaining power, an electronic device, and a storage medium.
Background
The shared bicycle and the shared electric bicycle solve the pain point of the public in the last kilometer of trip. When the user selects the shared electric bicycle, whether the electric bicycle is used can be selected according to the real-time remaining mileage of the shared electric bicycle, and the remaining mileage of the electric bicycle is known in real time in the riding process so as to avoid the electric quantity of the electric bicycle from being exhausted in the riding process. The remaining mileage of the electric bicycle is related to the remaining capacity of the battery of the electric bicycle, and the more the remaining capacity is, the longer the remaining mileage is. Therefore, the remaining capacity of the electric bicycle battery needs to be accurately acquired so as to calculate the accurate remaining riding mileage.
Currently, the most commonly used methods for acquiring the remaining battery capacity include two methods: the intelligent central control acquires a discharge curve of the battery, inquires the discharge curve by acquiring the current voltage of the battery and searches the residual electric quantity corresponding to the current voltage; the intelligent central control obtains the remaining capacity of the Battery by communicating with a Battery Management System (BMS), wherein the BMS is a Battery Management System built in the Battery and can manage the charging and discharging processes of the Battery and calculate the remaining capacity of the Battery.
However, the first method has the problems that the voltage change is very small in the whole discharge curve, and the voltage obtained by the intelligent central control has an error of 0.1-1V, which can cause a great error in the residual capacity searched for in the discharge curve, and can reach more than 50% in serious cases; the second method has a problem that the BMS calculates the current discharged to the outside of the battery by sampling the voltage difference between both ends of the resistor, and since the current discharged to the outside can reach up to 15A or more, the resistance of the sampling resistor can only be selected to be a very small resistance, and thus for a small current (for example, below 50 mA), the BMS cannot detect the small current, and thus the calculated remaining power of the BMS has a large error from the actual remaining power when the electric bicycle is not started.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a remaining power determining method according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step 110, detecting the electric quantity consumed by the intelligent central control of the electric vehicle during the period when the vehicle is not started;
and step 120, when the electric vehicle is started, determining the current accurate residual capacity of the electric vehicle based on the electric quantity consumed by the intelligent central control during the period that the vehicle is not started and the residual capacity information currently acquired by the battery management system.
Specifically, when the electric vehicle is stationary and not started, the intelligent central control of the electric vehicle still works at the moment, and the consumed electric quantity comes from the battery. Since the operating current of the smart central control is very small, typically around 20mA, in which case the BMS cannot calculate the amount of power consumed by the part, the amount of power consumed by the smart central control during the vehicle non-start period can be individually detected in order to accurately calculate the remaining power of the battery when the electric vehicle is not started.
When the electric vehicle starts, the current accurate residual capacity of the electric vehicle can be determined by comprehensively and intelligently controlling the electric quantity consumed during the period that the vehicle is not started and the residual capacity information currently acquired by the battery management system BMS. Because in this step, when the electric vehicle starts, the electric quantity consumed by the intelligent central control during the period of non-starting of the vehicle and the residual electric quantity information currently acquired by the BMS are considered, even if the working current of the intelligent central control is small and the electric quantity consumed by the intelligent central control is not calculated in the residual electric quantity information calculated by the BMS, the current residual electric quantity of the battery can be accurately calculated and displayed for the riding user to refer to.
According to the method provided by the embodiment of the invention, the electric quantity consumed in the vehicle non-starting period is controlled through independently detecting the intelligence of the electric vehicle, and when the electric vehicle is started, the current accurate residual electric quantity of the electric vehicle is determined based on the electric quantity consumed in the vehicle non-starting period through intelligent control and the residual electric quantity information currently acquired by the battery management system, so that the accuracy of determining the residual electric quantity can be improved.
Based on the above embodiment, step 110 specifically includes:
detecting current consumed by the intelligent central control during a period when the vehicle is not started;
and integrating the current consumed by the intelligent central control in the vehicle non-starting period according to time to obtain the electric quantity consumed by the intelligent central control in the vehicle non-starting period.
Specifically, the current consumed by the intelligent central control in the period when the vehicle is not started can be detected in real time. And integrating the current consumed by the intelligent central control in the vehicle non-starting period according to time to obtain the electric quantity consumed by the intelligent central control in the vehicle non-starting period. Here, the higher the frequency of the current consumed by the intelligent central control is detected, the more accurate the electric quantity information obtained by integration is, so that the frequency of the current detection may be set according to the requirements of the actual application scenario, which is not specifically limited in the embodiment of the present invention.
Based on any embodiment, the detecting of the current consumed by the intelligent central control in the vehicle non-starting period specifically includes:
collecting current consumed by the intelligent central control during the period that the vehicle is not started based on a current sensor built in the intelligent central control;
or determining the current consumed by the intelligent central control during the period that the vehicle is not started based on the voltage at two ends of the sampling resistor connected with the intelligent central control in series and the resistance value of the sampling resistor.
Specifically, in order to detect the current consumed by the intelligent central control unit during the period when the vehicle is not started, a high-precision current sensor can be arranged in the intelligent central control unit, and the current consumed by the intelligent central control unit during the period when the vehicle is not started can be directly acquired. In addition, a sampling resistor can be connected with the intelligent central control in series, the voltage at the two ends of the sampling resistor is collected, then the specific value between the voltage at the two ends of the sampling resistor and the resistance value of the sampling resistor is calculated by utilizing the ohm law, and the current consumed by the intelligent central control during the period that the vehicle is not started is calculated.
Based on any of the above embodiments, step 120 specifically includes:
when the electric vehicle is started, the electric quantity consumed by the intelligent central control in the vehicle non-starting period and the residual electric quantity information currently acquired by the battery management system are uploaded to the server, and the server receives the accurate residual electric quantity obtained after residual electric quantity correction is carried out on the electric quantity consumed by the intelligent central control in the vehicle non-starting period and the residual electric quantity information currently acquired by the battery management system.
Specifically, when the electric vehicle is started, the amount of power consumed by the intelligent central control unit during the period in which the vehicle is not started, which is determined in the previous step, may be uploaded to the server together with the information on the remaining power currently acquired by the battery management system BMS, and the server may correct the remaining power by combining the amount of power consumed by the intelligent central control unit during the period in which the vehicle is not started and the information on the remaining power currently acquired by the battery management system BMS. And then, receiving the accurate residual capacity corrected by the server, and recording and displaying the accurate residual capacity.
Based on any of the above embodiments, performing remaining power correction based on the power consumed by the intelligent central control during the period when the vehicle is not started and the remaining power information currently acquired by the battery management system specifically includes:
and subtracting the electric quantity consumed by the intelligent central control in the vehicle non-starting period from the residual electric quantity information currently acquired by the battery management system to obtain the accurate residual electric quantity.
Specifically, since it is difficult for the battery management system to detect a small current, and the current consumed by the intelligent central controller itself is small during the vehicle is not started, the battery management system does not count the amount of power consumed by the intelligent central controller itself when detecting the remaining power of the battery. Therefore, when the remaining capacity is corrected, the information of the remaining capacity currently acquired by the battery management system can be subtracted from the electric capacity consumed by the intelligent central control during the period when the vehicle is not started, so that the accurate remaining capacity can be obtained.
Based on any embodiment above, after the electric vehicle starts, the method further includes:
acquiring residual electric quantity information acquired by a battery management system in real time to serve as the current accurate residual electric quantity of the electric vehicle;
the residual electric quantity information collected by the battery management system is obtained by integrating the discharge current of the battery in time to obtain the consumed electric quantity and subtracting the consumed electric quantity from the rated electric quantity of the battery.
Specifically, after the electric vehicle is started, each electric device in the electric vehicle starts to operate, so that the working current after the electric vehicle is started is large and can be accurately detected by the battery management system. Therefore, after the electric vehicle is started, the residual electric quantity information acquired by the battery management system can be acquired in real time and used as the current accurate residual electric quantity of the electric vehicle, and the residual electric quantity information acquired by the battery management system does not need to be corrected.
The battery management system monitors the discharging process of the battery, so that the residual electric quantity information acquired by the battery management system can be obtained by integrating the discharging current of the battery with time to obtain the current consumed electric quantity, and subtracting the consumed electric quantity from the rated electric quantity of the battery.
