[0048] Referring to the drawings Figure 1 , Figure 1 is a main flowchart of the charging strategy verification method according to an embodiment of the present application. As shown in FIG. 1, the method includes the following steps: Figure 1As shown, the method mainly comprises the following steps S1-S4.

[0049] S1, obtaining historical battery swap records of the battery swap station in a continuous time T;

[0050] In this embodiment, compared with other selection of charging strategies according to real-time battery swap records, the historical battery swap records of the battery swap station in a continuous time T are obtained, which can reflect the running state of the current battery swap station and will not affect the normal operation of the battery swap station due to verification of the charging strategy. The continuous time T can be flexibly selected according to the specific battery swap station, and the purpose is to intercept the battery swap running state of the battery swap station. Specifically, 1 week, 1 month or 3 months can be selected.

[0051] In one embodiment, the historical battery swap information recorded in the historical battery swap records includes but is not limited to battery swap time and the corresponding first battery SOC value. For convenience of description, the battery swap time is sequentially recorded as t1, t2, … t n-1 n , and the corresponding first battery SOC value is sequentially recorded as SOC t1 , SOC t2 , … SOC tn-1 , SOC tn .

[0052] S2, simulating battery swap by a simulation model according to the historical battery swap records;

[0053] In one embodiment, before simulating battery swap by a simulation model according to the historical battery swap records, the verification method comprises: establishing a first SOC list, the first SOC list recording the SOC values of the batteries to be swapped in the battery swap station. The first SOC list can more intuitively reflect the existing battery situation in the battery swap station.

[0054] In one embodiment, referring to Figure 2 , Figure 2 is a main step flow diagram of simulating battery swap by a simulation model according to one embodiment of the present application, simulating battery swap by a simulation model according to the historical battery swap records, comprising steps S20-S22:

[0055] S20, obtaining the first battery SOC value corresponding to the battery swap time from the historical battery swap records.

[0056] Specifically, according to the specific distinction of the battery swap time and the first battery SOC value in the historical battery swap records, the battery swap time t1 and the first battery SOC value SOC t1 corresponding to t1 are obtained from the historical battery swap records. ​

[0057] S21, filling the information of the battery with the largest SOC value in the first SOC list into the second SOC list.

[0058] In the embodiment, the battery swap simulation is performed, i.e., a customer comes to the battery swap station to swap the battery. The battery swap station needs to swap the battery with the largest SOC value in the battery swap station to the customer. The SOC value of the battery swapped to the customer can present the satisfaction of the customer to the battery swap to a certain extent. The customer will want to swap the battery with a large SOC value, i.e., the larger the SOC value of the battery swapped to the customer, the higher the satisfaction of the customer. On the other hand, the SOC value of the battery swapped to the customer can also reflect whether the battery swap station can operate normally. Therefore, the information of the battery to be swapped to the customer is filled into the second SOC list as a basis for evaluating whether the charging strategy meets the normal operation of the battery swap station.

[0059] S22, replacing the largest SOC value in the first SOC list with the first battery SOC value.

[0060] In the embodiment, the battery swap simulation is performed, i.e., a customer comes to the battery swap station to swap the battery. The customer swaps the battery with less power to the battery swap station, and the battery swap station swaps the battery with the largest SOC value in the battery swap station to the customer. At this time, the customer gets the battery with the largest SOC value in the battery swap station, and the battery swap station gets the battery with less power from the customer. The first SOC list records the SOC values of the batteries to be swapped in the battery swap station, and the largest SOC value is selected from the SOC values, i.e., the battery with the largest SOC value in the battery swap station is replaced with the first battery SOC value, i.e., the battery with less power from the customer. Specifically, the largest SOC value in the first SOC list is replaced with the first battery SOC value SOC t1 .

[0061] In one embodiment, the battery swap is simulated by the simulation model according to the historical battery swap record, and further comprising a step S50:

[0062] S50, traversing all battery swap times in the historical battery swap record, and filling the corresponding battery SOC values into the first SOC list and the second SOC list, respectively.

[0063] In the embodiment, step S50 traverses the battery swap time and simulates the battery swap. Specifically, after the battery swap event at the battery swap time t1 is completed, the battery swap simulation at the battery swap time t2 in the historical battery swap record is performed, i.e., steps S20-S22 are performed on the premise that the battery swap time is t2. Specifically, the first battery SOC value corresponding to the battery swap time t2 is obtained; the information of the battery with the largest SOC value in the first SOC list at the current time (t2) is filled into the second SOC list; the current largest SOC value in the first SOC list is replaced with the SOC value corresponding to t2 t2. Thus, the loop is traversed until the last battery swap time t in the historical battery swap record n , obtaining a second SOC list recording the SOC values of the batteries swapped to the customer within the continuous time T, and a first SOC list recording the SOC values of the batteries swapped from the customer to be charged.

[0064] In one embodiment, according to the historical battery swap record, the simulated battery swap by the simulation model further comprises: simulating charging according to the charging strategy and updating the first SOC list in real time. The first SOC list records the SOC values of the batteries to be swapped in the battery swap station. When simulating charging according to the charging strategy, the batteries in the battery swap station are charged, and the first SOC list needs to be updated in real time at this time, so that the battery swapped to the customer in the subsequent time is the battery with the maximum SOC value in the battery swap station at the current time.

[0065] S3, calculating the electricity fee consumed by the charging strategy to be tested according to the simulated battery swap.

[0066] Referring to Figure 3 , Figure 3 is the main step flowchart of calculating the electricity fee consumed by the charging strategy to be tested according to the simulated battery swap of one embodiment of the present application. As Figure 3 shown, it comprises steps S30-S35:

[0067] S30, sequentially recording two adjacent battery swap times in the historical battery swap record as a first battery swap time and a second battery swap time according to time sequence.

[0068] In this embodiment, the first battery swap time occurs before the second battery swap time. Specifically, the first battery swap time is recorded as t1, and the second battery swap time is recorded as t2 according to the historical battery swap record.

[0069] S31, uniformly dividing the time from the first battery swap time to the second battery swap time into several time periods.

[0070] In this embodiment, the purpose of dividing the time is to more accurately calculate the electricity fee consumed when charging the battery. Since the time range from t1 to t2 is large, and the time for a battery to be fully charged is less than the time range from t1 to t2, it is not accurate to directly use the time range from t1 to t2 to calculate the electricity fee. Therefore, the time range from t1 to t2 is divided into several time periods. A certain battery may complete charging in a certain time period within the time range from t1 to t2, at which time the remaining time for calculating the electricity fee is no longer calculated. That is, it is fully charged and no longer needs to be charged.

[0071] Further, the time period can be adjusted according to specific conditions, for example, 1 min, 30 s or 1 s. In order to calculate the specific power consumption more accurately, the time period is selected as 1 s.

[0072] S32, according to the charging strategy to be tested, the charging rate of each time period is obtained.

[0073] In this embodiment, the number of batteries that need to be charged in each time period is different, and the corresponding charging rate is also different. The charging rate combination includes c1, c2, c3…c n where n is the number of batteries.

[0074] In one specific embodiment, according to the tested charging strategy, the charging rate combination of t1 to t1+1s is obtained.

[0075] S33, the electricity price corresponding to the time period is obtained;

[0076] In one specific embodiment, the electricity price corresponding to the time period of t1 to t1+1s is obtained. Further, before the simulation is performed, the step electricity price table information can also be input in advance in the simulation model, and the corresponding electricity price is directly called according to the time period.

[0077] S34, according to the charging strategy, the electricity fee required by the battery charging in each time period is calculated;

[0078] In one specific embodiment, because the SOC values of each battery are different, the electricity fee of each battery in each time period needs to be calculated. Taking 1 s as an example, the electricity fee of each battery in 1 s is calculated, and the electricity fees consumed by each battery are added to obtain the electricity fee required by the battery charging in t1 to t1+1s. The calculation formula of the electricity fee of each battery in 1 s is as follows:

[0079]

[0080] wherein, c n the battery charging rate (generally 0-1.5), P the rated power of the battery, p the electricity price, SOC n the current SOC value of the battery (0-100).

[0081] S35, according to the electricity fee required by each time period, the total electricity fee required from the first battery replacement time to the second battery replacement time is obtained.

[0082] In the embodiment, the total electricity fee consumed by each section is accumulated, and the total electricity fee required from the first battery replacement time to the second battery replacement time is obtained. Specifically, the total electricity fee of the time section t1 to t1+1s is obtained according to steps S32-S34; the time section t1+1s to t1+2s is obtained by performing steps S32-S34; and steps S32-S34 are repeated until t1+ns=t2. The electricity fee of each time section is accumulated to obtain the total electricity fee required from the battery replacement time t1 when the first battery replacement event occurs to the battery replacement time t2 when the second battery replacement event occurs.

[0083] In one embodiment, the step S60 of calculating the electricity fee consumed by the to-be-tested charging strategy according to the simulation battery replacement is further included.

[0084] S60, all the first battery replacement time to the second battery replacement time in the historical battery replacement record is traversed to obtain the total electricity fee required for completing the historical battery replacement according to the charging strategy.

[0085] In the embodiment, a plurality of battery replacement events are recorded in the historical battery replacement record, and the electricity fee required in the time section between two battery replacement events is calculated, i.e., the electricity fee of the time section from the first battery replacement time to the second battery replacement time. Specifically, the electricity fee required in the time section from t1 to t2 is calculated according to steps S30-S35; the electricity fee required in the time section from t2 to t3 is calculated according to steps S30-S35; and steps S30-S35 are repeated until the electricity fee of the time section from t n-1 to t n is calculated. The calculated electricity fee of the time sections t1-t2, t2-t3,..., t n-1 to t n is accumulated, and the electricity fee consumed by the charging strategy in the continuous time T is obtained.

[0086] S4, under the premise of meeting the normal operation of the battery replacement station, the electricity fee required by different charging strategies in the continuous time T is compared to select the optimal charging strategy.

[0087] In the embodiment, the second SOC list is the basis for evaluating whether the charging strategy meets the normal operation of the battery replacement station. Different customer groups face different requirements for the data distribution of the SOC values in the second list. For example, if the customer group facing the battery replacement station is a taxi, the requirement for the data distribution in the second SOC list will be relatively high, for example, the number of battery SOC values of 90 needs to be higher than 85%, and the condition for meeting the normal operation of the battery replacement station is met. Relative to the customer group facing private cars or business circles, the requirement for the data distribution in the second SOC list will be relatively low. Under the premise of meeting the normal operation of the battery replacement station, the charging strategy with the least electricity fee required in the continuous time T is selected as the optimal charging strategy.

[0088] In the technical scheme of the present application, by acquiring historical battery replacement record data in the battery replacement station, the battery replacement events of the historical battery replacement record in the battery replacement station are simulated by a simulation model, so that the charging strategy is verified, the best charging strategy can be quickly found, the result of the verification has high persuasiveness, the time for strategy verification is greatly shortened, and the influence of the strategy verification process on the normal operation of the battery replacement station is avoided.
