Network topology structure of converter station, power conversion method of electric vehicle, and converter station

Abstract

The invention discloses a network topology structure of a converter station, a power conversion method of an electric vehicle and the battery swap station. The structure is characterized in that the network topology structure of the battery swap station comprises a three-layer switch, an electric vehicle battery swap module, at least one battery pack charging cabinet, a control module and a communication module; the electric vehicle battery replacing module, at least one battery pack charging cabinet, the control module and the communication module are electrically connected with the three-layer switch; each battery pack charging cabinet comprises a charging switch and a plurality of integrated control panels, the charging switch is electrically connected with the three-layer switch, and the plurality of integrated control panels are electrically connected with the charging switch respectively. According to the network topology structure of the battery swap station, the station fallingefficiency can be greatly improved, the reliability and safety of network communication of the battery swap station are improved, the outdoor arrangement of the battery swap station can be facilitated, and resource waste is reduced.

Description

technical field [0001] The invention relates to the technical field of battery swapping stations, in particular to a network topology of a battery swapping station, a method for battery swapping of electric vehicles, and a battery swapping station. Background technique [0002] With the country's policy support for the development of battery-swapping electric vehicles, electric vehicle battery-swapping stations have increasingly become an important direction for future development. At present, the power supply methods of electric vehicle power batteries are generally divided into two methods: plug-in and battery replacement. There are two modes of plug-in charging, slow charging and fast charging. However, the plug-in charging method has the following defects: 1. The initial investment cost of the battery is relatively large, which hinders the popularization of electric vehicles to a certain extent; 2. The charging time is too long. The time spent is too long, very inconven...

However, the plug-in charging method has the following defects: 1. The initial investment cost of the battery is relatively large, which hinders the popularization of electric vehicles to a certain extent; 2. The charging time is too long. The time spent is too long, it is very inconvenient, and it is far from satisfying people's needs

[0003] In the existing technology, the switching station has various functions, complex structure, long landing time, and due to the outdoor layout of the switching station, the network implementation is difficult and the reliability is not strong enough, so it is necessary to provide a more effective solution
