Electric vehicle battery box tracking system and method

Abstract

The invention discloses a tracking system for a battery box in a charging station of an electric automobile. The tracking system comprises a monitor center and multiple station-level monitor subsystems, wherein the monitor center comprises a monitor host computer, a database server and an alarm; and each station-level monitor subsystem comprises four layers, namely a monitor layer, a network layer, a data acquisition layer and a terminal layer, wherein the monitor layer comprises a monitor computer which is connected with the monitor center through a special electric power network, the network layer comprises a Zigbee master control module, one or more Zigbee routing modules and one or more Zigbee terminal modules, the data acquisition layer comprises an RFID (radio frequency identification) reader which is used for acquiring the RFID information of the battery box and transmitting the information to a Zigbee network, and the terminal layer comprises the battery box and an RFID tag. According to the system, by the RFID technology and the Zigbee network, the battery box of the electric automobile is effectively tracked and managed, thus the effective maintenance of the battery and the safe operation of the electric automobile are ensured.

Description

technical field [0001] The invention relates to a battery box tracking system, in particular to a battery box tracking system for an electric vehicle charging and swapping station based on Zigbee technology and RFID technology. Background technique [0002] Zigbee technology is a low-power personal area network protocol based on the IEEE802.15.4 standard. The technology specified under this agreement is a short-distance, low-power wireless communication technology. This name comes from the eight-character dance of bees, because bees (bees) use the "dance" of flying and "buzzing" (zig) to shake their wings to communicate with their companions the location information of pollen, that is to say, bees rely on this way Form a communication network in the group. It is characterized by close range, low complexity, self-organization, low power consumption, low data rate, and low cost. It is mainly suitable for automatic control and remote control fields, and can be embedded in var...

Problems solved by technology

[0006] Similarly, in the prior art, there are also applications for tracking single batteries through RFID technology. For example, the patent application number: 201010538487.0 discloses "RFID battery tracking and recycling system and battery tracking and recycling method". However, it is the tracking of single batteries. Due to the large number of batteries in the battery box of electric vehicles, it is unrealistic to attach RFID tags to all of them, and the signals will interfere with each other when the data is collected. This method cannot To realize the tracking of the battery box, a new tracking system must be explored
