Problems solved by technology

[0011] First, in the charging and swapping station, including the existing charging mode and battery swapping mode, it is necessary to store a large number of self-contained batteries, store electric energy intensively during the valley power period, and mainly perform charging or battery swap operations during the non-valley power period, that is, Supplementing electric energy for electric vehicles; the disadvantage is that the investment cost of storing a large number of energy storage batteries is huge, and actually lowers the overall utilization efficiency of the battery;
[0012] Second, in the charging and swapping station, set up a large-scale parking lot equipped with charging piles, park the vehicles in the parking lot, and charge during the off-peak period; the disadvantage is that the investment is still high, and the location of the parking lot Facing a dilemma and poor convenience for users;
[0013] Third, large-scale construction of decentralized charging facilities, that is, to increase the vehicle-to-pile ratio to 1:1; in fact, if various factors are considered, only when the vehicle-to-pile ratio reaches 1:2 or 1:3 can users be able to The convenience of charging is generally felt; but the reality is that there are great difficulties and gaps in reaching the goal of a vehicle-to-pile ratio of 1:1

Embodiment 1

[0051] This embodiment introduces the structural form of the battery pack supporting dynamic configuration capacity of the present invention.

[0052] as attached figure 1 , 2 As shown, the structure of the battery pack 3 supporting dynamic configuration capacity is: including the battery pack main frame 301, an external electrical interface 302, a plurality of sub-frames 303, and corresponding to each sub-frame 303, a plurality of internal electrical interfaces 304 are set;

[0053] The battery pack 3 includes several modular battery packs 305, and the modular battery packs 305 can be correspondingly installed and fixed in each sub-frame 303, and connected to the internal electrical interface 304;

[0054] Each internal electrical interface 304 is connected to the external electrical interface 302 respectively, and is aggregated and output through the external electrical interface 302;

[0055] Each sub-frame 303 can choose to install or not install the modular group batter...

Embodiment 2

[0078] In this embodiment, an electric vehicle battery dispatching system based on a battery replacement mode and its operating method are introduced.

[0079] as attached Figure 4 As shown, the structural characteristics of the electric vehicle battery deployment system are:

[0080] The charging and swapping station network 2 includes several charging and swapping stations 2a and a management dispatching center 2b; as indicated by the N1 arrow, the management dispatching center 2b performs unified management and dispatching of several charging and swapping stations 2a;

[0081] The spare battery pack 3b is stored in each charging and swapping station 2a, and the capacity of each spare battery pack 3b can be dynamically adjusted in the charging and swapping station 2a, and arranged and combined to form several groups with different capacities; as shown by the N2 arrow , each charging and swapping station 2a can mutually adjust the backup battery pack 3b; the specific dispat...

Abstract

The invention provides an electric car battery deployment system based on an electric vehicle switching mode. The electric car battery deployment system is characterized in that an electric car (1), acharging and switching station network (2), and a battery pack (3) supporting the dynamic configuration capacity are included, the electric car is combined with a customized charging and switching station, power batteries are dynamically deployed according to the application requirements, thus car-electric separation is realized, and the utilization efficiency of the batteries is improved.

Description

technical field [0001] The invention relates to an electric vehicle battery allocation system and method based on the battery exchange mode. The electric vehicle is combined with a customized charging and exchange station, and the power battery is dynamically allocated according to the application requirements, thereby realizing the separation of the vehicle and electricity and improving the utilization of the battery. Efficiency, which belongs to the technical field of electric vehicle system design. Background technique [0002] For a long time, the power supply of electric vehicles has been a thorny problem. In order to improve performance and convenience, there are two main technical means used in existing applications, namely fast charging technology and battery replacement technology (battery replacement technology, such as reference 1). The above two technical means have certain requirements for the construction of infrastructure; and their focus is to improve the co...
