Abstract
Description
Technical Field
[0001] This invention relates to the field of mobile energy storage vehicles and deployment systems, and in particular to combined mobile energy storage vehicles and deployment systems. Background Technology
[0002] New energy applications are a crucial direction for future development, especially with the rapid advancement of new energy vehicles in recent years, leading to their increasing popularity. However, the development of supporting infrastructure such as charging stations for new energy vehicles still requires time, thus creating some challenges for their practical use. Mobile power generators are already widely used in emergency rescue and power supply, but their use, particularly lithium battery-based mobile power generators, poses certain risks in densely populated areas.
[0003] This case is proposed to address or improve upon the shortcomings or deficiencies of existing technologies. Summary of the Invention
[0004] This invention is achieved by the following technical solution: Based on the above two points, this invention proposes using intrinsically safe lead-carbon batteries as the energy storage medium, and achieving optimized scheduling through combination methods and deployment of terminal systems to compensate for the low energy density of lead-carbon batteries. Functionally, it has application scenarios such as peak shaving and valley filling, emergency backup, and emergency charging for new energy vehicles.
[0005] The innovation of this invention lies in: 1) This system includes a deployment terminal system and a combination of different types of energy storage vehicle systems. The energy storage vehicle system is divided into functional vehicles and battery vehicles according to the differences in the vehicle body. Functional vehicles are fixed-point vehicles, that is, they are stationed at the application location after they start work. Battery vehicles are dispatchable vehicles, that is, after the current battery vehicle's energy storage battery is discharged, it is taken over by a subsequent dispatched battery vehicle. This method saves the number of vehicle heads used and the total driving time. 2) The energy storage vehicle system adopts a separate energy storage vehicle structure, that is, the vehicle body and the frame can be separated. Depending on the actual application scenario, when used for short time, it can be used directly on the trailer. When used for long time, the vehicle body lifting device can be used independently at a designated location, reducing the idle rate of the trailer. 3) The carriage is divided into a functional carriage and a battery carriage. According to the discharge requirements of the application scenario, the dispatch center optimizes the scheduling to realize online expansion and capacity increase, breaking the capacity bottleneck of a single energy storage vehicle and meeting more application scenarios. At the same time, by optimizing the scheduling to reduce the trailer vacancy rate, it can also reduce the limitation of the area provided by the usage scenario. 4) It has more complete functions, and can be used not only as an emergency backup, but also as a peak shaving and valley filling and peak summer power supply guarantee, and as an emergency charging for new energy vehicles; 5) Using lead-carbon batteries as the energy storage medium, coupled with pack-level fire protection, makes it safer and more reliable, with no safety risks even in areas with very high population density; The modular mobile energy storage vehicle consists of three parts: the front, the frame, and the cargo compartment. The front and frame are of a common type, while the cargo compartment is divided into two categories: a functional compartment and a battery compartment.
[0006] In addition to the standard configuration, an IoT terminal system has been added to the front of the vehicle to record the vehicle's route and location, providing a basis for deployment. The functional compartment mainly includes: lead-carbon battery clusters, BMS management unit, PCS, combiner box, cable reel, charging pile, and fire protection module, etc. Its function is functional management and energy management; through the EMS system, it can switch between charging pile power supply, grid-connected power supply, off-grid power supply, and grid-connected / off-grid switching power supply. The battery compartment mainly includes: lead-carbon battery clusters, BMS management unit, PCS and fire protection module; its function is energy storage and power conversion. The dispatching process is as follows: The computer terminal system receives the deployment task, which should include the location distance, load type, estimated load power (P), and guarantee time (T). The computer terminal should receive the current status of each numbered battery compartment in real time, mainly including the current remaining power (SOC) and the current battery health (SOH). The computer terminal determines the initial deployment battery compartment vehicle number X1 and the initial deployment functional compartment Y1 based on P, T, SOC, and SOH, and configures the corresponding vehicle front Z1, Z2, etc. The vehicle is deployed according to the computer terminal. The vehicle activates the Internet of Things system to record the route and road conditions. When it reaches the deployment location, the mileage S and the departure time t1 are recorded. Wiring was completed according to the requirements of the on-site application scenario, and the energy storage system was started to provide power, completing the initial deployment. The vehicle then returned to the base. Simultaneously, the computer terminal determines a correction coefficient α based on road conditions, initial departure time, and departure route. Based on α, it determines the time t2 required for the second round of supplementary deployment. Similarly, it can calculate the time t3 for the third round of supplementary deployment, the time t4 for the fourth round of supplementary deployment, and so on... After power supply begins, the data from the energy storage system is transmitted back to the computer terminal via 4G signal. The computer terminal calculates the remaining power supply time T1 of the deployed energy storage system based on the actual power load P1 and the current remaining power SOC. By combining the time difference between T1 and t2, the start time for the second round of vehicle deployment is determined, and so on, to determine the subsequent supplementary deployment times.
[0007] The function switching process works as follows: Function switching is implemented in the function compartment, mainly involving wiring and control methods. The functions that can be implemented and the operation methods are as follows. 1. Grid-connected operation: After the battery compartment is connected to the combiner cabinet, it supplies power to the AC function cabinet. By switching internally and setting the PCS to grid-connected mode, the user terminal can be directly connected from the grid-connected access point. 2. Off-grid operation: After the battery compartment is connected to the combiner cabinet, it supplies power to the AC function cabinet. By switching internally and setting the PCS to off-grid mode, the user terminal can be directly connected from the grid access point. 3. On-grid and off-grid switching: After the battery compartment is connected to the combiner cabinet, it supplies power to the AC function cabinet. Through internal switching and setting the PCS to grid-connected mode, the user load can be directly connected from the grid-connected access point and the off-grid access point. 4. Charging piles charge new energy vehicles: After the battery compartment is connected to the combiner cabinet, it supplies power to the charging piles. The PCS working mode is adjusted to off-grid mode. At this time, charging pile 1 and charging pile 2 can charge new energy vehicles at the same time.
[0008] The advantages and positive effects of this invention are: Establish communication and data sharing between the Internet of Things, battery management system, and terminal computer; The Internet of Things (IoT) collects and analyzes road condition information, while incorporating the correction coefficient developed in this patent to improve accuracy. The battery management system incorporates an intelligent SOC algorithm to collect battery status data. The unique computer terminal platform combines battery-collected data with IoT-collected data and uses its own algorithms to provide a reasonable deployment plan.
[0009] The new energy storage vehicle is integrated according to its functions: 1. First, a split-type energy storage vehicle is adopted to ensure that the front of the vehicle and the cabin can be separated, which is a prerequisite for meeting the deployment process; 2. The cabin is divided into two categories for more reasonable use. Attached Figure Description
