Description

Technical Field

[0001] The present invention relates to the technical field of power battery charging management, and in particular to a charging pile charging current adjustment method, device, equipment and storage medium. Background Art

[0002] At present, the charging current of power batteries is getting larger and larger. The maximum charging current of a single air-cooled charging gun is only 300A, which can no longer meet the needs of power batteries. The cost of liquid-cooled charging piles is relatively high. At present, for systems with a charging current of more than 300A, a dual-gun charging solution is generally adopted. At present, the current distribution of dual-gun charging mainly adopts the master pile and slave pile distribution strategy. The master pile and the slave pile are fixedly evenly divided into charging currents, or the master pile is charged first. When the charging current of the master pile cannot meet the battery demand, the charging current is allocated to the slave pile. The strategy of fixed average current distribution between the master pile and the slave pile may not fully meet the charging power demand of the battery when the output power of the charging pile is inconsistent. With the current distribution strategy of master pile priority, the charging current of the charging seat will be in an unbalanced state for a long time, resulting in differences in the degree of aging of the charging seat. This strategy also does not take into account the overcurrent capacity of the charging circuit. When the maximum output current of the charging pile is large and the battery demand current is also large, it may cause the charging circuit to overcurrent and create safety risks.

[0003] Therefore, how to improve the charging efficiency of power batteries is a technical problem that needs to be solved urgently. Summary of the invention

[0038] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0039] Furthermore, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. Some of the blocks shown in the drawings are functional entities and do not necessarily correspond to physically or logically separate entities.

[0040] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0041] Reference Figure 1 , Figure 1 FIG. 1 is a flow chart of a charging current adjustment method for a charging pile provided by the present invention. Figure 1 As shown, the method comprises the steps of:

[0042] Step S101: Based on the comparison result of the maximum output current of the first and second charging piles with the maximum charging current currently allowed by the battery and the maximum overcurrent capacity allowed by the charging circuits of the first and second charging piles, the charging current of each charging circuit is allocated.

[0043] Specifically, before allocating the charging current to each charging circuit, the following steps are performed:

[0044] Determine the charging mode of the battery, which includes single-gun charging and dual-gun charging; if the charging mode of the battery is determined to be single-gun charging, take the minimum value among the maximum charging current value currently allowed by the battery, the maximum output current value of the charging pile, and the maximum charging current value allowed by the charging circuit to request current for charging.

[0045] Based on the comparison result of the maximum output current of the first and second charging piles with the maximum charging current currently allowed by the battery and the maximum overcurrent capacity allowed by the charging circuits of the first and second charging piles, the charging current of each charging circuit is allocated, including:

[0046] If the maximum output current values ​​of the first charging pile charging circuit and the second charging pile charging circuit are both less than half of the maximum charging current value currently allowed by the battery;

[0047] The smaller value is taken from the maximum output current value of the first charging pile and the maximum continuous overcurrent value allowed by the charging circuit of the first charging pile as the charging current value of the charging circuit of the first charging pile;

[0048] The smaller value between the maximum output current value of the second charging pile and the maximum continuous overcurrent value allowed by the charging circuit of the second charging pile is taken as the charging current value of the charging circuit of the second charging pile.

[0049] For easy understanding, an example is given. When the battery is in the charging configuration stage, the charging mode is determined. If it is single-gun charging, the minimum value is taken among the maximum charging current value currently allowed by the battery, the maximum output current value of the charging pile, and the maximum charging current value allowed by the charging circuit to request current for charging. In the single-gun charging mode, the battery system is charged by connecting to the charging pile through any charging interface, and the other charging interface is not charged. In this case, the minimum value is taken among the maximum charging current value currently allowed by the battery, the maximum output current value of the charging pile, and the maximum charging current value allowed by the charging circuit to request current for charging.

[0050] In dual-gun charging mode, the battery system is charged by connecting to the charging pile through any charging interface, and the other charging interface is connected to the charging pile for charging at the same time, or the previous charging circuit is charging, which is regarded as dual-gun charging mode.

[0051] If dual-gun charging is used, the charging current of the two charging circuits is allocated according to the maximum output current value of the first charging pile and the second charging pile, the maximum continuous overcurrent value allowed by the first charging circuit and the second charging circuit, and the maximum charging current value allowed by the current battery. The specific allocation method is as follows:

[0052] First, compare the maximum output current values ​​of the first charging pile and the second charging pile with half of the maximum charging current value currently allowed by the battery. It should be noted that, assuming there are 4 charging piles, the maximum output current value of each loop charging pile is compared with 25% of the maximum charging current value currently allowed by the battery to determine whether the maximum output current value of the loop charging pile is less than 25% of the maximum charging current value currently allowed by the battery. If there are three charging piles, then it is equal to 33%. It can be understood that the maximum charging current value currently allowed by the battery is determined based on the number of charging piles, and the maximum output current value of each loop charging pile is compared with it.

[0053] In one embodiment, if the number of charging piles is 4, if the maximum output current value of the charging circuit of each charging pile is less than 25% of the maximum charging current value currently allowed by the battery;

[0054] The smaller value is taken from the maximum output current value of each charging pile and the maximum continuous overcurrent value allowed by the charging circuit of each charging pile as the charging current value of the charging circuit of each charging pile.

[0055] Specifically, take two charging piles as an example: if the maximum output current value of the charging pile of the first circuit is less than half of the maximum charging current value currently allowed by the battery, and the maximum output current value of the charging pile of the second circuit is less than half of the maximum charging current value currently allowed by the battery, then the first charging circuit requests the charging current value I1 to take the smaller value between the maximum output current value of the first charging pile and the maximum continuous overcurrent value allowed by the first charging circuit, and the second charging circuit requests the charging current I2 to take the smaller value between the maximum output current value of the second charging pile and the maximum continuous overcurrent value allowed by the second charging circuit.

[0056] In one embodiment, if the maximum output current value of the charging circuit of the first charging pile is less than half of the maximum charging current value currently allowed by the battery, and the maximum output current value of the charging circuit of the second charging pile is greater than or equal to half of the maximum charging current value currently allowed by the battery;

[0057] The smaller value is taken from the maximum output current value of the first charging pile and the maximum continuous overcurrent value allowed by the charging circuit of the first charging pile as the charging current value of the charging circuit of the first charging pile;

[0058] The minimum value among the difference between the maximum output current value of the second charging pile and the charging current value of the charging circuit of the first charging pile, the difference between the maximum charging current value currently allowed by the battery and the charging current value of the charging circuit of the first charging pile, and the maximum continuous overcurrent value allowed by the charging circuit of the second charging pile is taken as the charging current value of the charging circuit of the second charging pile.

[0059] For example: if the maximum output current value of the first charging pile is less than half of the maximum charging current value currently allowed by the battery, and the maximum output current value of the second circuit charging pile is greater than or equal to half of the maximum charging current value currently allowed by the battery, then the first charging circuit requests the charging current value I1 to take the smaller value between the maximum output current value of the first charging pile and the maximum continuous overcurrent value allowed by the first charging circuit, and the second charging circuit requests the charging current I2 to take the minimum value among the difference between the maximum output current value of the second charging pile and I1, the difference between the maximum charging current value currently allowed by the battery and I1, and the maximum continuous overcurrent value allowed by the second charging circuit.

[0060] If the maximum output current values ​​of the first and second charging pile charging circuits are both greater than or equal to half of the maximum charging current value currently allowed by the battery;

[0061] The smaller value is taken as the charging current value of the first charging pile charging circuit, from half of the maximum charging current value currently allowed by the battery and the maximum continuous overcurrent value allowed by the charging circuit of the first charging pile;

[0062] The smaller value is taken as the charging current value of the second charging pile charging circuit, from half of the maximum charging current value currently allowed by the battery and the maximum continuous overcurrent value allowed by the charging circuit of the second charging pile.

[0063] For example: if the maximum output current value of the first charging pile is greater than or equal to half of the maximum charging current value currently allowed by the battery, and the maximum output current value of the second charging pile is greater than or equal to half of the maximum charging current value currently allowed by the battery, then the first charging circuit requests a charging current value I1 that is the smaller of half of the maximum charging current value currently allowed by the battery and the maximum continuous overcurrent value allowed by the first charging circuit, and the second charging circuit requests a charging current value I2 that is the smaller of half of the maximum charging current value currently allowed by the battery and the maximum continuous overcurrent value allowed by the second charging circuit.

[0064] Step S102: Based on the allocated charging current of each charging circuit, during the battery charging process, the maximum charging current allowed by the current battery, the charging current of each charging circuit and the actual charging current of each charging circuit are obtained in real time to dynamically adjust the charging current of each charging pile.

[0065] Specifically, if the difference between the charging current value of the first and second charging pile charging circuits and the actual charging current value is greater than or equal to the preset difference, and the duration reaches the set duration;

[0066] Or the difference between the charging current value of the first and second charging pile charging circuits and the actual charging current value is less than or equal to the preset difference;

[0067] The current charging current distribution strategy for the first and second charging pile charging circuits is maintained, and the charging current of each charging circuit is continuously requested for charging.

[0068] In one embodiment, if the difference between the charging current value of the first charging pile charging circuit and the actual charging current value is greater than or equal to the preset difference, and the difference between the charging current value of the second charging pile charging circuit and the actual charging current value is less than the preset difference;

[0069] The charging current value of the charging circuit of the first charging pile is adjusted to be equal to the actual current value of the charging circuit of the first charging pile within the previous preset time;

[0070] The minimum value among the difference between the maximum output current value of the second charging pile and the charging current value of the charging circuit of the first charging pile, the difference between the maximum charging current value currently allowed by the battery and the charging current value of the charging circuit of the first charging pile, and the maximum charging current value allowed by the charging circuit of the second charging pile is taken as the charging current of the charging circuit of the second charging pile.

[0071] For ease of understanding, an example is given. The maximum charging current value allowed by the current battery, the requested charging current values ​​of the first circuit and the second circuit, and the actual charging current values ​​of the first circuit and the second charging circuit are obtained. The current difference K1 of the requested charging current value of the first charging circuit minus the actual charging current value is compared with the preset difference K, and the current difference K2 of the requested charging current value of the second charging circuit minus the actual charging current value is compared with the preset difference K. The preset difference K is K=10A in this example, and the duration reaches the preset time T. The time T is T=5 seconds in this example, where 0A<k≤50A is generally taken, and the duration reaches the preset time T. T is generally taken as 1 to 10 seconds. If it lasts for 5 seconds, the difference K1 ≥ 10A, and the difference K2 < 10A, then adjust the charging current value I1 requested by the first charging circuit to be equal to the actual current value of the first charging circuit in the previous 5 seconds, and the charging current I2 requested by the second charging circuit is the minimum value among the difference between the maximum output current value of the second charging pile minus I1, the maximum charging current value currently allowed by the battery - I1, and the maximum charging current value allowed by the second charging circuit.

[0072] In the dual-gun charging configuration stage of this application, the power battery obtains the maximum output current value of the charging pile, compares the maximum output current value of the charging pile with half of the current battery allowable charging current value, and allocates the charging current of each circuit in combination with the maximum overcurrent capacity allowed by the charging circuit; in the dual-gun charging process, the power battery obtains the maximum charging current value allowed by the current battery and the requested charging current value of the first and second circuits, the actual charging current value of the first and second charging circuits in real time, compares the difference between the current difference of the requested charging current value of the first and second charging circuits minus the actual charging current value and the preset difference value K, and the duration reaches the preset time value, and dynamically adjusts the charging current value of the first and second charging circuits in combination with the maximum continuous overcurrent value allowed by the charging circuit. At the same time, the overcurrent capacity of the charging circuit is taken into account to maximize the charging performance of the battery and the charging pile, shorten the charging time, and improve charging safety.

[0073] Reference Figure 2 , Figure 2 FIG. 1 is a schematic diagram of a charging pile charging current adjustment device provided by the present invention, such as Figure 2 As shown, the device comprises:

[0076] Further, in a possible implementation manner, the adjustment module is further configured to adjust the current value of the first and second charging pile charging circuits to a predetermined value if the difference between the charging current value and the actual charging current value is greater than or equal to the preset difference, and the duration reaches the set duration;

[0082] Furthermore, in a possible implementation manner, a judgment module is further included, which is used to judge a charging mode of the battery, and the charging mode includes single-gun charging and dual-gun charging;

[0083] If the battery charging mode is determined to be single-gun charging, the minimum value among the maximum charging current value currently allowed by the battery, the maximum output current value of the charging pile and the maximum charging current value allowed by the charging circuit is taken to request current for charging.

[0084] Furthermore, in a possible implementation manner, the allocation module is further configured to: if the maximum output current values ​​of the first charging pile charging circuit and the second charging pile charging circuit are both less than half of the maximum charging current value currently allowed by the battery;

[0086] The smaller value between the maximum output current value of the second charging pile and the maximum continuous overcurrent value allowed by the charging circuit of the second charging pile is taken as the charging current value of the charging circuit of the second charging pile.
