[0006] The operation strategy includes a battery operation model and a charging operation model;

[0007] The battery operation model includes the following establishment steps:

[0008] A1: Determine the battery swap cycle time interval and divide it into several stages;

[0009] A2: The cloud operation platform counts the number of batteries replaced at each stage within a certain battery replacement cycle time interval;

[0010] A3: Calculate and determine the range of the number of batteries to be replaced at each stage within a single battery replacement cycle time interval, and determine the number of batteries required at each stage;

[0011] A4: Taking the current battery replacement cycle time stage as the starting point, ensure that the number of fully charged batteries in at least X consecutive stages meets the number of batteries required in the stage, where X is an integer greater than 1;

[0012] A5: When the battery at any stage in step A4 is replaced, prepare for charging the fully charged battery required for the next stage after the continuous X stages starting from this stage;

[0013] The charging operation model includes the following establishment steps:

[0014] B1: The cloud operation platform is connected to the power grid and obtains the real-time electricity price information of the power grid;

[0015] B2: Determine the peak, flat and valley period information of electricity prices in each stage of the battery operation model based on electricity price information;

[0016] B3: In step A5, during the flat and / or valley time intervals of the phase in which the battery is replaced, the battery is charged so that it meets the number of fully charged batteries in a phase after the continuous X phases.

[0017] Preferably, the operation strategy further includes a battery replacement cost calculation model;

[0024] D2: Based on the battery replacement time, the battery replacement cost is determined by calculating the electricity fee period described in the battery replacement time and the total time required to fully charge.

[0025] Preferably, in step B3, if the first stage of the non-battery replacement cycle time interval in step A4 is the first battery replacement stage in the cycle time stage, the number of fully charged batteries in the stage before the replaced stage is settled into the subsequent stage of the replaced stage, and it is determined whether the subsequent stage meets the conditions of step A4. If not, the battery is charged in the flat section and / or valley section of the replaced stage to ensure that the conditions of step A4 are met.

[0032] Among them, by setting the service coefficient, when the electricity price is at the peak period, the operating cost of the operator can be effectively reduced, and when the electricity price is at the off-peak period, the consumption cost of the consumer can be effectively reduced. Under this operating model, customer stickiness can be enhanced, especially the frequency of battery replacement by customers during off-peak periods can be increased, which reduces the pressure of municipal power supply during peak periods to a certain extent.

[0040] The battery operation model includes the following establishment steps:

[0041] A1: Determine the battery swap cycle time interval and divide it into several stages;

[0042] A2: The cloud operation platform counts the number of battery replacements at each stage within a number of battery replacement cycle time intervals. The battery replacement cycle time intervals in step A1 can be divided into equal time periods in units of days. In this battery replacement cycle time interval, regular working days (Monday to Friday) and weekends can be determined separately, effectively ensuring the battery demand under different conditions.

[0043] A3: Calculate and determine the range of the number of battery replacements at each stage within a single battery replacement cycle time interval, and determine the number of batteries required at each stage. When doing this, the actual battery replacement situation every day of the week can be determined based on business data, such as two to three weeks of business data, and the number required at each stage can be determined by using the average value method. If the difference between weekdays and Sundays is not considered when dividing the battery replacement cycle time interval, the daily data can be counted and the number of batteries required for each stage can be determined by the normal distribution calculation method. The standard deviation value under this calculation method is formulated according to the actual situation;

[0044] A4: Taking the current battery swap cycle time stage as the starting point, ensure that the number of fully charged batteries in at least X consecutive stages meets the number of batteries required in the stage, where X is an integer greater than 1, preferably 2, which can effectively reduce the battery reserve of the battery swap station;

[0060] Among them, the battery replacement fee also includes service fees. The fees paid by customers include service fees and battery replacement costs. The calculation formula for the total battery replacement fee is as follows:

[0061] The total cost of battery replacement = k*service fee + battery replacement cost; k is the service coefficient, when the electricity price is in the flat and off-peak period, k is less than 1, when the electricity price is in the peak and peak period, k is greater than 1. For example, in the flat and off-peak period, k can be 0.9, in the peak and peak period, k can be 1.15.

[0062] Among them, each charging position corresponds to an extension meter, and data between the extension meter and the cloud operation platform is exchanged to further accurately confirm the actual charging power.
