Problems solved by technology

The traditional battery scheduling model often takes the scheduling delay time as the expected penalty, and cannot quantify the economic losses caused by the scheduling delay to the enterprise
In addition, shared energy storage between the site and the grid remains to be utilized when the site batteries are idle

Embodiment

[0084] like figure 1 As shown, a battery management control method based on dispatch cost, based on charging loss and shared energy storage dispatch vehicle route optimization management, by considering time-varying electricity price, time-varying charging power and correcting battery capacity, can effectively reduce power loss and Battery loss, and considering that the energy storage sharing between the site and the grid can effectively reduce the waste of power resources, the battery dispatches the vehicle to complete the dispatched transportation, which specifically includes the following steps:

[0085] S1. Obtain the site location information of the charging and swapping station and the battery remaining information of the dispatching vehicle, and calculate the state of charge of the dispatching vehicle according to the driving model of the dispatching vehicle;

[0086] S2. According to the battery remaining information and state of charge, combined with the battery charg...

Abstract

The present invention relates to a battery management control method based on scheduling cost, which specifically includes: S1, acquiring station location information and battery remaining information, and calculating the state of charge of the dispatching vehicle according to the driving model of the dispatching vehicle; S2, combining battery charging Model, calculate the charging time of the dispatched vehicles, the charging power of the station and the energy storage power, and calculate the power flow by the power distribution system to obtain the dispatching constraints; At this moment, the power loss and battery loss are calculated, and then the scheduling cost objective function is calculated; S4. According to the scheduling cost objective function and scheduling constraints, a battery scheduling cost optimization model is generated, and the genetic algorithm is used to solve it to obtain the battery scheduling optimization path. Compared with the prior art, the invention has the advantages of improving the utilization rate of the battery, reducing the loss in the scheduling process, improving the energy storage utilization of the battery, and the like.

Description

technical field [0001] The invention relates to the technical field of electric vehicle battery charging and replacing, in particular to a battery management control method based on dispatch cost. Background technique [0002] At present, the charging and swapping technology has become more and more mature. A fully functional charging and swapping station can perform charging and swapping services for multiple electric vehicles. At the same time, it is also more perfect in terms of detecting power parameters and transmitting power quality. However, there are still some problems in practical application. For example, in the management of battery replacement, due to the difference between the theory and the actual situation, the dispatching cost is high; the charging method of the battery is time-varying power charging, but the current battery loss adopts a constant The power is calculated, resulting in a large deviation; the idle batteries of the swap station also need to be ...
