Detailed Description
In the following description specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without these specific details. In the present invention, specific numerical references such as "first element", "second device", and the like may be made. However, specific numerical references should not be construed as necessarily subject to their literal order, but rather construed as "first element" as opposed to "second element".
The specific details set forth herein are merely exemplary and may be varied while remaining within the spirit and scope of the invention. The term "coupled" is defined to mean either directly connected to a component or indirectly connected to the component via another component.
Preferred embodiments of methods, systems and devices suitable for implementing the present invention are described below with reference to the accompanying drawings. Although embodiments are described with respect to a single combination of elements, it is to be understood that the invention includes all possible combinations of the disclosed elements. Thus, if one embodiment includes elements A, B and C, while a second embodiment includes elements B and D, the invention should also be considered to include A, B, C or the other remaining combinations of D, even if not explicitly disclosed.
As shown in fig. 1, a first embodiment of the present invention provides a method for determining a charging scheme of an electric vehicle, which includes the following steps.
Step S10, determining that at least one user of the electric vehicle may command the charging location.
Specifically, in this step, the user-controllable charging position may be jointly determined based on the in-vehicle positioning module, the electric vehicle charging position recording module, and the driving recording module of the electric vehicle.
It can be understood that the data provided by the vehicle-mounted positioning module, the electric vehicle charging position recording module and the electric vehicle driving recording module are dynamically updated. If the user can control the charging position to change, the system can update the position along with the training; in addition, the system also provides for assisting the user in setting, through a human-machine interface, the locations where these users may command the charging, e.g., "home".
After determining the user disposable charging locations, the system records and stores the disposable charging locations in non-volatile memory.
Step S12 is to acquire the information on the time zone of the highest or lowest electricity prices in the corresponding administrative district, for each user' S available charging position.
Each administrative district (province, city and autonomous district) has different periods of high and low electricity prices, and according to the scheme of the invention, the city corresponding to the charge position which can be controlled by each user is determined.
On one hand, information of the high and low electricity prices of various regions in China can be obtained from an external data source through investigation to form a database, and the database is deployed in a network background and has the capability of automatic updating; on the other hand, the database is queried based on the output result of step S10 or based on the disposable charging location information read from the nonvolatile memory, and the individual electricity rate high and low period information of the city corresponding to the disposable charging location is determined for each user.
The electricity price high and low time period information should at least include an electricity price high time period and an electricity price low time period. Further, the electricity prices corresponding to the electricity price peak time period and the electricity prices corresponding to the electricity price low peak time period are also included. It is understood that, if the power rate high and low period information of a certain administrative district includes more detailed time-of-use power rate information, according to the present embodiment, such time-of-use power rate information can also be acquired.
And step S14, determining the current position of the electric automobile.
In this step, the current position of the electric vehicle may be determined by the vehicle-mounted positioning module, or may be determined by a smart phone of the user, and the user may manually set current position information via the human-computer interaction interface.
Specifically, this step is performed after the system obtains an indication that the user desires to charge, and then obtains the current location information of the electric vehicle from the on-board positioning module or in another manner.
Step S16, determine whether the current position is one of the user-controllable charging positions.
Here, if it is determined that the current location does not belong to one of the user-controllable charging locations, which means that the user may travel by driving the electric vehicle in an out-of-range situation, the user generally wants to be able to immediately charge the electric vehicle once finding a charging station or a charging post without waiting for the arrival of the peak period of low electricity prices, which will choose not to perform step S18 any more, but to select immediate charging by listening to the user' S instruction.
Alternatively, in a case where the user indicates that the user does not care to wait for the arrival of the low-peak electricity price period, even if the current location of the electric vehicle does not belong to the charging location that the user can dominate, the charging scheme may be recommended to the user according to the information of the high-low electricity price period of the administrative district corresponding to the current location.
And step S18, recommending a charging scheme to the user based on the information of the high and low electricity prices of the administrative district corresponding to the current position and the expected use time of the user.
In this step, if the determination result of step S16 is yes, an optimal charging scheme is determined based on the information of the electricity price high and low periods of the administrative district corresponding to the current location, the expected usage time of the user, and the current electric quantity of the electric vehicle, so that the electric vehicle preferentially uses the electricity price low peak period for charging, thereby contributing to saving the charging cost.
The recommendation of the charging scheme to the user may be specifically implemented as: informing the user of the time required by the charging completion of the electric automobile; and the cost savings that can be achieved using the recommended charging scheme compared to conventional charging schemes. The charging scheme may be presented on a display screen of the electric vehicle or sent to a smartphone of a user associated with the electric vehicle.
As to the specifics of the charging scheme, immediate charging, wait for charging, delay charging, pause charging, and any combination of these options may be included.
Preferably, the charging scheme may be any one of the following: 1) continuously charging for a first period of time from a current time; 2) after waiting for the second time period, starting to continuously charge for a third time period; and 3), after the charging reaches the fourth time period from the current time, suspending the charging and resuming the charging in the fifth time period.
As an example, in the shanghai, the electricity rate low peak period is 0: 00-6: 00, peak period 6: 00-24: 00, the time the user desires to use the vehicle is the next morning 6: 30 (this time can be set on the interactive interface of the electric vehicle, or with an associated smartphone), the time period required for charging is calculated according to the current battery capacity: (1) assuming a full charge takes 4 hours, then one can choose to use a voltage between 0: 00-4: 00 this time period to charge the vehicle; (2) assuming a full charge takes 8 hours, one can choose to do this at 22: 00-24: 00 (peak hours) and 0: 00-6: 00 (low peak period in shanghai) the vehicle is continuously charged for 2 contiguous time periods.
According to the first embodiment, the user can not only obtain the optimal charging scheme, so that the charging cost is saved, but also conveniently apply the charging scheme, inconvenience caused by manual operation is reduced, and excellent use experience is obtained.
It will be appreciated that the above method may be implemented on a computer storage medium having stored thereon computer-executable instructions that, when executed by a processor, will perform the method provided by the first embodiment described above.

Specifically, the disposable charging position determination unit 201 acquires data from an on-vehicle positioning module (e.g., GPS module), an electric vehicle charging position recording module, and a travel recording module of the electric vehicle, for determining at least one user disposable charging position of the electric vehicle.
The electricity price period information obtaining unit 202 is coupled to the charge position determining unit 201, and obtains an output result thereof as one of the inputs, and the electricity price period information obtaining unit 202 further uses an external data source as another input to obtain the electricity price period height information of each administrative district, so as to respectively obtain the electricity price period height information of the corresponding administrative district for each charge position that can be controlled by each user.
The current position determination unit 203 may directly determine the current position of the electric vehicle using the in-vehicle positioning module.
The charging scenario recommendation unit 21 is coupled to the disposable charging location determination unit 201, the electricity rate period information acquisition unit 202, and the current location determination unit 203, and specifically performs the following actions: if the current location is located in one of the charging locations that the user can control, the charging scheme recommending unit 21 recommends the charging scheme to the user based on the information of the electricity price high and low periods of the administrative district corresponding to the current location and the expected use time of the user, so that the electric vehicle preferentially uses the electricity price low peak period for charging.
According to a preferred embodiment of the present invention, at least a portion of the above-described system may be implemented using a distributed set of computing devices connected by a communications network, or may be implemented based on a "cloud". In such a system, multiple computing devices operate together to provide services by using their shared resources.
