< method examples >

Fig. 2 is a schematic flow chart of a battery electric quantity measuring method provided by an embodiment of the present disclosure, which may be implemented by a cost-sensitive embedded device facility, specifically, a lock on a shared vehicle, for example, the lock on the vehicle 1000 in fig. 1, and the battery electric quantity measuring method of the present embodiment is described below by taking the lock shown in fig. 1 as an example.

As shown in fig. 2, the method of the present embodiment may include the following steps S2100-S2300, which will be described in detail below.

In step S2100, the total power consumption of all power consuming devices in the lock at the current time is obtained.

The power consumption equipment refers to various equipment which is integrated in the lock and needs to be driven by electric power. For example, the device may be a processor, a communication device, a positioning module, a speaker, etc. in the vehicle lock.

The total power consumption amount, which may also be referred to as an accumulated power consumption amount, is a total value of power consumed by all power consuming devices in the vehicle lock within a target time range.

Specifically, the total charge of the battery of the vehicle lock is generally fixed, for example, the total current may be generally expressed as "100%", and the power consumption of each power consumption device in the vehicle lock in different operating states is often different. Therefore, in this embodiment, in order to accurately obtain the remaining power of the battery of the vehicle lock, the total power consumption of all power consuming devices in the vehicle lock may be counted, and an initial remaining power that can reflect the remaining power of the battery to a certain extent is obtained according to the total power consumption of the battery and the total power consumption.

In one embodiment, the obtaining the total power consumption of all power consuming devices in the vehicle lock includes: acquiring historical operation data of first power consumption equipment, wherein the first power consumption equipment is any one of all the power consumption equipment; obtaining a first power consumption amount of the first power consumption equipment according to the historical operation data; and obtaining the total power consumption according to the first power consumption.

The historical operating data is data indicating a historical operating state of the power consuming apparatus within a target time range.

The target time range may be a time range from a first time to a current time, where the first time is earlier than the current time, and specifically may be an activation time of the lock; alternatively, the target remaining capacity of the battery may be acquired at any time before the current time.

According to the above description, the first remaining capacity of the battery at the first time is the target remaining capacity of the battery of the vehicle lock calculated at the first time.

In practice, the historical operating data may be obtained from a system log of the vehicle lock, and the historical operating data at least includes each operating state of the corresponding power consumption device during the operating process, and the start-stop time corresponding to each operating state.

Taking the power consuming device as an example of a communication device in the vehicle lock, the communication device is, for example, a 2G communication module. In practice, the operating state of the 2G communication module generally includes a standby state and an active state. When the vehicle and the server perform data interaction, the 2G module is in an activated state, and the 2G communication module is normally switched to a standby state after the interaction is finished. Accordingly, the historical operational data of the 2G communication module may be in the form of "standby state, start time t1_ start, end time t1_ end", "active state, start time t2_ start, end time t2_ end", … "," standby state, start time tn-1_ start, end time tn-1_ end "," standby state, start time tn _ start, end time tn _ end ".

In practice, the power consumption of each power consuming device in the lock in different operating states, that is, the power consumption current, is often fixed. Therefore, after the historical operation data of each power consumption device is obtained, the power consumption corresponding to each power consumption device can be rapidly calculated according to the historical operation data, and the total power consumption of all the power consumption devices in the lock can be obtained by obtaining the sum of the power consumption of each power consumption device.

Specifically, the obtaining a first power consumption amount of the first power consumption device according to the historical operation data includes: according to the historical operating data, obtaining the state type of the working state of the first power consumption equipment and the starting and stopping time corresponding to the working state; obtaining a power consumption current value corresponding to the state type according to second preset mapping data, wherein the second preset mapping data are used for reflecting the power consumption current value corresponding to the first power consumption equipment in different working states; and obtaining the first power consumption according to the starting and stopping time and the power consumption current value.

The state type may be a unique identifier that identifies an operating state. Taking the 2G communication module as an example, the standby state may be denoted as "10" and the active state may be denoted as "11".

During specific implementation, the working time of the power consumption equipment in the lock under different working states can be accurately obtained according to historical operating data of the power consumption equipment in the lock; in addition, the second preset mapping data, that is, data reflecting the power consumption current values of the power consumption device in different operating states, may also be obtained through a preliminary test. Therefore, the total working duration of the power consumption equipment in different working states can be correspondingly obtained according to the historical operating data of the power consumption equipment; then, multiplying the working time length of each working state by the power consumption current value corresponding to the power consumption equipment in the working state, and obtaining the power consumption of the power consumption equipment in the working state; the power consumption of the power consumption equipment in each working state is obtained in sequence, and the power consumption of the power consumption equipment in the corresponding target time range can be obtained by adding the power consumption of the power consumption equipment in sequence.

Still taking the power consuming device as an example of a 2G communication module in a car lock, it can be known from the above description that the historical operating data may be in the form of "standby state, start time t1_ start, end time t1_ end", "active state, start time t2_ start, end time t2_ end", … "," standby state, start time tn-1_ start, end time tn-1_ end "," standby state, start time tn _ start, and end time tn _ end "; setting the power consumption current value obtained by the test in the standby state to be A1 and the power consumption current value in the activated state to be A2, the power consumption of the power consumption device in the target time range can be calculated by the following formula: the power consumption of the power consuming device is ((t1_ end-t1_ start) + … + (tn-1_ end-tn-1_ start)). a1+ ((t2_ end-t2_ start) + … + (tn _ end-tn _ start)). a 2.

In the above, how to obtain the power consumption of the power consuming device is described by taking the power consuming device as a communication device in the vehicle lock, for example, a 2G communication module. In specific implementation, the power consumption of each power consumption device in the lock in a target time range can be obtained according to the method; and then, adding the obtained power consumption amounts to obtain the total power consumption amount of all the power consumption equipment in the lock in the target time range.

After step S2100, step S2200 is performed to obtain an initial remaining capacity of the battery of the lock at the current time according to the first remaining capacity of the battery at the first time and the total power consumption.

After the total power consumption of all power consumption equipment in the lock is obtained through the method, the initial remaining power of the battery at the current moment can be calculated and obtained according to the first remaining power and the total power consumption of the battery of the lock at the first moment.

As can be seen from the related description in step S2200, the first remaining capacity may be a target remaining capacity of the battery of the lock acquired at the first time, where the first remaining capacity may be "100%" when the first time corresponds to the activation time of the lock.

In one embodiment, the following formula may be used to calculate the initial remaining capacity of the battery of the vehicle lock at the current moment: the initial remaining capacity ((first remaining capacity-total power consumption)/total battery capacity) × 100%.

However, in consideration of the individual dispersion of the power consumption of the power consuming apparatus, in order to improve the accuracy of the initial remaining power amount, the accuracy of the target remaining power amount is improved. In one embodiment, the obtaining the initial remaining capacity of the battery at the current time according to the first remaining capacity and the total power consumption of the battery of the vehicle lock at the first time includes: acquiring a difference value between the first remaining power and the total power consumption; and obtaining the initial residual capacity according to the difference and a weight coefficient for obtaining the initial residual capacity at the current moment.

Specifically, after a difference is calculated according to a first remaining capacity of the battery at a first time and a total power consumption of all power consumption devices, the difference can be further calibrated through a pre-calculated weight coefficient to obtain an initial remaining capacity with high accuracy; that is, the initial remaining capacity of the battery may be calculated using the following equation: the initial remaining capacity ((first remaining capacity-total power consumption) × weight coefficient/total battery power) × 100%.

In this embodiment, the weighting factor for calibrating the initial remaining capacity is a value greater than 0 and not greater than 1, and the weighting factor can be obtained by calculation in advance; in addition, in the subsequent step, in the process of calibrating the initial remaining capacity by using the preset calibration algorithm to obtain the target remaining capacity, the weight coefficient is updated, so that the accuracy of the initial remaining capacity is further improved.

Step S2300, calibrating the initial remaining capacity by using a preset calibration algorithm, to obtain a target remaining capacity of the battery at the current time.

Specifically, after the initial remaining capacity of the battery of the vehicle lock at the current time is obtained through the above steps, the target remaining capacity of the battery may be obtained by calibrating the initial remaining capacity.

In one embodiment, the obtaining the target remaining capacity of the battery at the current time by calibrating the initial remaining capacity using a preset calibration algorithm includes: acquiring the reference residual capacity of the battery at the current moment; and calibrating the initial residual capacity by using the reference residual capacity to obtain the target residual capacity.

The reference remaining capacity is a reference value reflecting the remaining capacity of the battery at the present time.

In one embodiment, the obtaining the reference remaining capacity of the battery includes: acquiring a discharge voltage value of the battery at the current moment; and inquiring the residual capacity matched with the discharge voltage value as the reference residual capacity in first preset mapping data, wherein the first preset mapping data is used for reflecting the corresponding relation between the discharge voltage value and the residual capacity of the battery.

In specific implementation, the first preset mapping data can be obtained according to a discharging voltage and electric quantity curve of the vehicle lock obtained through a pre-test.

For example, in the case that the current discharge voltage value of the battery is V1, the reference remaining capacity at the current time may be queried to be SOC1 according to the first preset mapping data.

In one embodiment, the calibrating the initial remaining capacity using the reference remaining capacity to obtain the target remaining capacity includes: calculating a calibration value according to the initial residual capacity and the reference residual capacity; and acquiring an absolute value of a difference between the initial remaining capacity and the reference remaining capacity; acquiring a difference value between the initial residual capacity and the calibration value as the target residual capacity under the condition that the initial residual capacity is greater than the reference residual capacity and the absolute value of the difference value is not less than a preset threshold value; and acquiring a sum of the initial remaining capacity and the calibration value as the target remaining capacity when the initial remaining capacity is smaller than the reference remaining capacity and an absolute value of the difference is not smaller than the preset threshold; and taking the initial residual capacity as the target residual capacity when the absolute value of the difference is smaller than the preset threshold.

The calibration value is a value for calibrating the initial remaining capacity. In the present embodiment, the calibration value can be calculated by the following formula: the calibration value is ((| initial remaining power amount-reference remaining power amount |)/2.

In this embodiment, after the initial remaining capacity and the reference remaining capacity are compared and the calibration value and the absolute value of the difference between the calibration value and the reference remaining capacity are obtained, the target remaining capacity of the battery of the vehicle lock at the current moment can be calculated and obtained through a preset algorithm.

For example, when the initial remaining capacity is greater than the reference remaining capacity and the absolute value of the difference between the initial remaining capacity and the reference remaining capacity is not less than the preset threshold, it indicates that the deviation between the calculated initial remaining capacity and the actual remaining capacity of the battery is large, and the initial remaining capacity needs to be reduced to a certain extent to calibrate the value thereof to obtain the target remaining capacity with high accuracy. Specifically, in this case, the target remaining capacity may be obtained by calculation with the following formula: the target remaining capacity is the initial remaining capacity-calibration value.

For another example, when the initial remaining capacity is smaller than the reference remaining capacity and the absolute value of the difference between the initial remaining capacity and the reference remaining capacity is not smaller than the preset threshold, it also indicates that the deviation between the calculated initial remaining capacity and the actual remaining capacity of the battery is large, and the initial remaining capacity needs to be increased to a certain extent to calibrate the value thereof to obtain the target remaining capacity with high accuracy. Specifically, in this case, the target remaining capacity may be obtained by calculation with the following formula: and the target residual capacity is equal to the initial residual capacity plus the calibration value.

For another example, when the absolute value of the difference between the initial residual capacity and the reference residual capacity is smaller than the preset threshold, it indicates that the initial residual capacity and the reference residual capacity are closer to each other, and at this time, the value of the initial residual capacity may be directly used as the value of the target residual capacity, that is, the target residual capacity is equal to the initial residual capacity.

In addition, as described in step S2200, in the process of performing step S2300 to calibrate the initial remaining capacity using the calibration algorithm described above to obtain the target remaining capacity, the value of the weight coefficient used for calculating the initial remaining capacity may be updated according to the magnitude and difference relationship between the initial remaining capacity and the reference remaining capacity.

Specifically, in an embodiment, the method provided in this embodiment further includes: and under the condition that the absolute value of the difference is not smaller than the preset threshold, updating a weight coefficient used for acquiring the initial residual capacity at a second moment according to the initial residual capacity and the reference residual capacity, wherein the second moment is later than the current moment.

For example, in a case where the initial remaining capacity is greater than the reference remaining capacity, and an absolute value of a difference between the two is not less than a preset threshold, a value of the weight at the next time may be obtained and the weight coefficient may be updated by calculating by the following formula: the weight coefficient is 1- ((initial remaining capacity-reference remaining capacity)/initial remaining capacity)/2.

For another example, when the initial remaining capacity is less than the reference remaining capacity, and the absolute value of the difference between the two is not less than the preset threshold, the value of the weight at the next time may be obtained and the weight may be updated by the following formula: the weight coefficient is 1+ ((initial remaining capacity-reference remaining capacity)/initial remaining capacity)/2.

For another example, when the absolute value of the difference between the two is smaller than the preset threshold, the value of the weighting coefficient at the next time is directly updated to 1.

As shown in fig. 3, when the target remaining power of the battery of the vehicle lock needs to be calculated, the initial remaining power calculation module may take the historical operation information of each power consumption device in the working process of the vehicle lock and the power consumption current value of each power consumption device in different working states as input, and output the initial remaining power to the calibration module; in the calibration module, reference residual capacity can be obtained according to the current discharge voltage value of the battery and the discharge voltage electric quantity curve of the battery; calibrating the initial residual capacity according to the reference residual capacity and outputting a target residual capacity; in addition, in the calibration process, an updated value of the weight coefficient may be output to the initial remaining power calculation module.

To sum up, in the method provided by the embodiment of the present disclosure, the total power consumption of all power consuming devices in the lock at the current time is obtained, and according to the first remaining power of the battery of the lock at the first time and the total power consumption, the initial remaining power of the battery at the current time can be obtained; and then, calibrating the initial residual capacity by using a preset calibration algorithm, so that the target residual capacity with higher accuracy can be obtained. Compared with the method for estimating the remaining capacity of the battery according to the discharge voltage of the battery in the prior art, the method provided by the embodiment can obtain the target remaining capacity of the battery of the vehicle lock more accurately on the premise of not increasing the hardware cost.
