Description
The application is a divisional application of the following applications, the application date of the original application: 2016, 04, 15, original application No.: 201610233503.2, title of original application: a method and apparatus for automatically searching for a charging device according to characteristics of an electric vehicle.

Furthermore, the electric quantity of the current vehicle battery can be detected, and whether the corresponding charging equipment can be reached or not is calculated. The two patents can solve the technical problem that the charging equipment cannot be found within the driving range without knowing where the charging equipment is located.
The third aspect is limited in that the output voltage range of the charging device does not necessarily satisfy the charging voltage required by the vehicle, not only because the charging voltage standards are not uniform, but also because the optimal charging voltage and current are different if the same electric vehicle battery is used to a different extent. That is, the same vehicle is charged with the same charging voltage and charging current, and the same vehicle has different battery usage levels and different current electric quantity, and the charging effect is different.
The limitation of the third aspect causes problems that: the charging voltage of the found charging equipment can not meet the requirement of vehicle charging, the charging current of the found charging equipment is too small, the charging is slow, and the like.

Detailed Description
Example 1
A method for automatically searching for charging equipment according to characteristics of an electric vehicle comprises the following steps:
a storage step: storing charging parameters of the charging equipment; the charging parameters comprise electrical information output by the charging equipment;
the collection step comprises: acquiring battery parameters of a vehicle; the battery information includes electrical information of the battery relating to a charging demand;
a comparison and selection step: comparing the charging parameters of the charging equipment with the battery parameters of the vehicle, and selecting the charging equipment with the charging parameters matched with the battery parameters of the vehicle;
an output step: and outputting the matched charging equipment to prompt the driver.
The above steps are explained in detail in the following order.
(1) The main body of the storage step is a client installed on the vehicle or a remote monitoring background. The charging parameters of the charging device may be stored in a database, the charging parameters including electrical information output by the charging device. The electrical information can be designed according to specific requirements. For example, the electrical information includes: the minimum output voltage of the charging equipment, the maximum output voltage of the charging equipment and the maximum output current of the charging equipment.
(2) The collecting step is to detect information obtained by the battery in real time through a related sensor on the vehicle, and specifically, the information can be transmitted to a vehicle bus after being collected. The step of collecting may also be accomplished by manual input from the driver. The main body of the collecting step is a client installed on the vehicle.
For comparison purposes, the battery parameters collected in the collecting step correspond to the charging parameters stored in the storing step. In this embodiment, the battery parameters include a vehicle charging minimum voltage and a vehicle charging maximum voltage. As other embodiments, a charging current range may also be included.
In the dc charging scheme, the vehicle charging minimum voltage and the vehicle charging maximum voltage are generally closely related to vehicle battery parameters, and are two static values, the vehicle charging minimum voltage is a charging voltage required by the vehicle battery when the electric quantity is the minimum, and the vehicle charging maximum voltage is a charging voltage required by the vehicle battery when the electric quantity is the maximum.
In the ac charging scheme, the minimum voltage for charging the vehicle, the maximum voltage for charging the vehicle, and the current required charging voltage of the vehicle are generally equal, and are a static value obtained by adding a variation range to a reference value of 220V or 380V.
If only the above-mentioned static values are used, it is obvious that these values can be manually input directly by the driver as the charging request. Specifically, after the vehicle identification code is manually input, the client determines the relevant battery parameters of the vehicle according to the vehicle identification code. A vehicle identification code comprising: the VIN number of the vehicle, the factory number of the manufacturer, the user-defined number and the like can clearly indicate the identification code of the vehicle.
If the current required charging voltage of the vehicle is also included, since the current required charging voltage is the charging voltage required by the vehicle under the current electric quantity, and is closely related to the current voltage of the vehicle battery, usually slightly higher than the current voltage of the vehicle battery, and is a dynamic value, and needs to be obtained in real time, it must be realized by a sensor or BMS on the vehicle, etc.
(3) If the main body of the storage step is a remote monitoring background, the collected output is transmitted to the remote monitoring background, the remote monitoring background is used for completing the comparison and selection step, the result is transmitted to the vehicle client, and the vehicle client outputs the result to prompt a driver. If the main body of the storage step is the vehicle client, the subsequent comparison selection and output are directly completed by the vehicle client.
The comparison and selection step is used for comparing and judging the charging parameters with the battery parameters to determine whether the charging parameters are matched with the battery parameters. The matching method is more, for example:
when the vehicle charging minimum voltage is not less than the charging device minimum output voltage and the vehicle charging maximum voltage is not greater than the charging device minimum output voltage, the charging device can charge the vehicle, namely the charging device can charge, and the matching is successful.
The following steps are repeated: in order to expand the selectivity of the charging device, the current charging required voltage can be used instead of the vehicle charging minimum voltage, and more chargeable charging devices can be selected by using the method because the current charging required voltage is not less than the vehicle charging minimum voltage.
(4) The output step is a process of informing the driver of the selected charging equipment, and the selected charging equipment can be output in a mode of marking on a map, or directly output in a list mode, or output in a voice mode.
In the above embodiment of the method, the battery parameter of the collecting step is used as a charging requirement, and is compared with the stored charging parameter. The charging requirement can be static information or dynamic information.
Furthermore, the charging requirements may include not only the electrical information of the battery, but also other information, and the following embodiments include more charging requirements.
Example 2
Unlike embodiment 1, the charging request further includes the position information of the current vehicle, and the purpose thereof is not only to find a charging device that can match the battery of the vehicle, but also to avoid that the current vehicle cannot reach due to the charging device being too far away, taking into account the distance between the current vehicle and the charging device. Thus:
accordingly, the database should also store the location information of the charging device.
The acquisition step is also used for acquiring the position information of the vehicle and the driving range information of the vehicle, or indirectly calculating to obtain the driving range information by acquiring the current electric quantity of the battery. Of course, the vehicle location, range may be entered by the driver or obtained via GPS.
In the comparison step, the charging equipment covered by the driving range of the vehicle is determined according to the driving range of the vehicle, the position information of the charging equipment and the position information of the vehicle; selecting a charging device with charging parameters matched with the battery parameters of the vehicle within the range of the driving range of the vehicle.
The driving range of the vehicle is generally obtained by dividing the residual capacity of the vehicle by the average kilometer power consumption of the vehicle. The vehicle remaining power is obtained in the manner described above, the average vehicle power consumption is generally obtained by comparing the total vehicle power consumption with the total vehicle mileage, and all vehicles have the total vehicle power consumption and the total vehicle mileage. Regarding the calculation of the driving range, the determination of the charging device covered by the driving range belongs to the prior art in the fields of digital maps and geographic information, and is not described in detail.
In order to more accurately match the charging requirement and the charging device in consideration of the driving range, the current charging voltage in the embodiment may be the current charging voltage in consideration of the driving range, that is, the charging voltage at the time of reaching the charging device is predicted by combining the distance from the charging device to the current position and the continuous decrease of the battery voltage due to the driving distance based on the current real-time voltage. For example, the real-time voltage is collected, the current charging required voltage is calculated to be a, and when the charging required voltage is matched with the current charging required voltage, the voltage is continuously reduced when the vehicle runs to the charging equipment, so that the charging required voltage when the vehicle runs to the charging equipment is predicted to be B.
In order to facilitate the driver, the available charging device locations may be sorted while being notified, and the round-trip distance, the length of the queue waiting time, the length of the charging time, the length of the queue plus the total charging time, and the like may be selected during sorting.
Of course, in order to achieve this, it is also necessary to monitor information of each charging device, such as acquiring a fault state of the charging device, an idle state of the charging device, a charging schedule, a charging remaining time, and the like. The monitoring work can be completed by the remote monitoring background.
The more information that is collected, the greater the freedom of choice for the driver, and the driver can be informed of the results in a variety of ways. For example, the system can be ranked according to different requirements, or scores can be given for the driver to select; the specific form can be similar to the mode that search-class APP is sorted according to distance and price.
Such as: according to the fault state, the idle state, the charging progress and the charging remaining time of the current charging equipment, the time that the current charging equipment can be used can be calculated. The time may be considered infinite when the charging device malfunctions, 0 when the charging device is idle, and equal to the remaining charging time when the charging device is in use. Accordingly, the waiting time of all the charging devices can be obtained, and all the charging devices can be sorted according to the waiting time.
For more complex scenarios, such as a charging device being located subordinate to a charging station, the availability and latency of the charging station may need to be computationally ordered. If there is a charging device available in the charging station, the charging station is available, and the waiting time of the charging station is the waiting time of the charging device with the shortest waiting time in the charging station. The flow of this approach is shown in fig. 1.
The invention also provides a device for automatically searching the charging equipment according to the characteristics of the electric automobile, which comprises the following components:
a storage module: storing charging parameters of the charging equipment; the charging parameters comprise electrical information output by the charging equipment;
an acquisition module: acquiring battery parameters of a vehicle; the battery information includes electrical information of the battery relating to a charging demand;

The modules of the device are actually steps realized by software, and the whole device is a software component for realizing the method shown in the embodiment.
The present invention has been described in relation to particular embodiments thereof, but the invention is not limited to the described embodiments. In the thought given by the present invention, the technical means in the above embodiments are changed, replaced, modified in a manner that is easily imaginable to those skilled in the art, and the functions are basically the same as the corresponding technical means in the present invention, and the purpose of the invention is basically the same, so that the technical scheme formed by fine tuning the above embodiments still falls into the protection scope of the present invention.
