Detailed Description
Embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
The terms "comprising" and "having" and any variations thereof in the description and claims of the application and in the foregoing drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
At present, when the electric automobile is charged in a direct current mode, if the charging current is larger than the required current, the electric automobile triggers an overcurrent protection mechanism, and the electric automobile stops receiving the charging pile for charging, so that the electric automobile cannot be fully charged.
In view of this, the present application provides a charging method, which adjusts the output current according to the real-time demand current of the power storage terminal, so as to avoid the power storage terminal triggering the overcurrent protection mechanism due to the output current being greater than the real-time demand current.
Referring to fig. 1, fig. 1 is a schematic flow chart of a charging method according to an embodiment of the application, the charging method is applied to a charging pile 10, and the method includes, but is not limited to, the following steps:
s101, acquiring real-time demand current of the power storage end.
The power storage end may be a power consumption device that needs to be charged, such as an electric vehicle or an electric vehicle 40. The electric storage end is provided with an overcurrent protection mechanism, and when the electric storage end is in a charging process, the electric storage end updates real-time demand current according to the stored electric quantity. For example, when the amount of electricity stored in the electricity storage terminal reaches 30% of the full state, the real-time demand current of the electricity storage terminal may be 5A, when the amount of electricity stored in the electricity storage terminal reaches 60% of the full state, the real-time demand current of the electricity storage terminal may be 5A, and when the amount of electricity stored in the electricity storage terminal reaches 95% of the full state, the real-time demand current of the electricity storage terminal may be reduced to 4A.
In the embodiment of the present application, when the charging pile 10 charges the electric storage terminal, the charging pile 10 communicates with the electric storage terminal to obtain the real-time required current of the electric storage terminal.
S102, if the real-time required current is smaller than a first preset value, charging the power storage end with a unit current, wherein the unit current is smaller than the real-time required current.
In the present application, in order to reduce the possibility of an overcurrent occurring when charging the power storage terminal, the power storage terminal is charged with a unit current.
The first preset value may be a rated current. Taking the electric automobile 40 as an example, the rated current of the electric automobile 40 is 5A, and when the electric automobile 40 is charged by the charging pile 10, the charging pile 10 can output the current of 5A to charge the electric automobile 40. When the electric vehicle 40 is about to be charged, the real-time required current of the electric vehicle 40 may be less than 5A, for example, when the stored electric quantity of the electric vehicle 40 reaches 95% of the full-charge state, the real-time required current of the electric vehicle 40 may be only 4A, if the electric vehicle 40 is charged with the electric vehicle 40 while still outputting the current of 5A, the electric vehicle 40 triggers the overcurrent protection mechanism to stop charging, so that the stored electric quantity of the electric vehicle 40 only reaches 95% of the full-charge state, and fails to be fully charged.
In the embodiment provided by the application, after the real-time demand current of the power storage end is obtained, the power storage end is charged by using the unit current, so that the power storage end is prevented from triggering an overcurrent protection mechanism.
The unit current is the minimum charging current. Illustratively, the charging post 10 includes a plurality of connected charging modules 14, and the current output by one charging module 14 without being electrically connected to the other charging modules 14 is a unit current, which may be understood as the minimum current that the charging post 10 outputs to charge other devices. The unit current is smaller than the real-time required current at the power storage terminal.
In the embodiment provided by the present application, if the real-time required current is smaller than a first preset value, charging the power storage terminal with a unit current, and cutting off the electrical connection of each charging module 14; one charging module 14 of the plurality of charging modules 14 is caused to charge the power storage terminal to control a current charged to the power storage terminal as a unit current.
S103, collecting the actual current charged by the power storage terminal by using the unit current, and determining the difference value between the real-time required current and the actual current.
In the application, in the process of charging the power storage terminal, the output current is inconsistent with the actual current due to control errors in the charging process.
For example, the unit current of the charging pile 10 is 0.1A, the charging pile 10 charges the power storage terminal with the unit current, and the actual current charged by the charging terminal to the power storage terminal may be 0.12A. In order to reduce errors, when the power storage end is charged by unit current, the actual current charged by the power storage end is collected, and the difference value of the real-time demand current of the power storage end and the collected actual current is calculated.
And S104, determining an output current for charging the power storage end based on the difference value and the actual current, and enabling the output current to be smaller than the real-time required current.
In the embodiment provided by the application, when the real-time demand current of the power storage terminal is smaller than the first preset value, the unit current is used as the initial output current for adjusting the power storage terminal to charge, and then the output current is adjusted in real time according to the actual current for charging the power storage terminal and the difference value between the real-time demand current and the actual current. In the process of adjusting the output current, the adjusted output current needs to be smaller than the real-time required current.
In an embodiment of the present application, when adjusting an output current for charging a power storage terminal, the method includes:
and determining the sum of one half of the difference value and the actual current as the output current, and charging the power storage end with the output current to avoid that the regulated output current is larger than the real-time required current.
The method further comprises the steps of:
and collecting real-time current for charging the power storage end, and determining a real-time difference value between the real-time required current and the real-time current.
In the embodiment provided by the application, the real-time current is the actual current for charging the power storage terminal.
And when the adjusted output current is used as the power storage end for charging, continuously collecting the real-time current for charging the power storage end, and calculating to obtain a real-time difference value of the real-time required current and the real-time current based on the real-time required current and the real-time current.
And determining whether to adjust the current to be the output current for charging the power storage terminal according to the real-time difference value of the real-time demand current and the real-time current.
And if the real-time difference value is smaller than or equal to a second preset value, continuously charging the power storage end by the real-time current.
And if the real-time difference value is larger than a second preset value, updating the output current based on the real-time difference value and the real-time current until the real-time difference value between the required current and the newly acquired real-time current is smaller than or equal to the second preset value.
The charging the power storage terminal with the output current includes: controlling connection of a part of the charging modules 14 of the plurality of charging modules 14; and the charging module 14, which is partially connected, outputs the output current to charge the power storage terminal.
The updating the output current based on the real-time difference and the real-time current includes: determining a sum of one-half of the real-time difference and the real-time current as an updated output current; and charging the power storage end with the updated output current.
Specifically, when charging the power storage terminal, the charging pile 10 continuously determines whether to enter the low-current charging mode according to the real-time required current. If the current I is required in real time 1 Above the first preset value, the dc charging pile 10 is charged in a high-current charging mode, for example, charging is performed with a rated current as the power storage terminal.
If the current I is required 1 And the charging pile 10 enters a small-current charging mode when the value is smaller than or equal to a first preset value. The output current of the charging pile 10 adjusted to the electric storage terminal for charging may be, for example, a unit current, I 0 May be about 0A.
The charging pile 10 performs power distribution, only one charging module 14 is used for charging the electric storage end, and the actual current I for charging the electric storage end is obtained through sampling of the ammeter 11 21 If the current I is required in real time 1 And the actual current I 21 The difference value of (2) is larger than a second preset value, the output current to the power storage end is regulated, and the output current I for charging the power storage end is enabled 3 ＝I 0 +1/2(I 1 -I 21 )。
To output current I 3 Sampling the real-time current charged by the power storage end to obtain a real-time current I again 22 If the current I is required in real time 1 And the actual current I 21 The difference value of (2) is larger than a second preset value, the output current to the power storage end is regulated, and the output current I for charging the power storage end is enabled 4 ＝I 3 +1/2(I 1 -I 22 ) And (3) not adjusting the output current for charging the power storage terminal until the difference value between the real-time required current and the sampled real-time current is smaller than or equal to a second preset value.
