Smart charging pile data transmission device, processing system and method

Abstract

The invention discloses a smart charging pile data transmission device, a processing system and a processing method, and the transmission device can receive battery state data sent by a lower chargingpile through a first communication module, request public and private key pairs from a third-party agent, and upload the public and private key pairs to a cloud server after finishing encryption. Through the re-encryption technology, when the device uploads the battery state data of the user, even if the secret key is stolen, an attacker cannot konw the uploaded content. The device, system and method is suitable for data transceiving and security encryption when the charging pile needs to upload state data of a user during battery charging to the cloud. Besides, the cloud server stores the data in the MPT data structure according to the keywords, and based on the data integrity verification mechanism, the user is allowed to verify the correctness and integrity of the data on the premise that the user does not need to download the original message, so that the downloading time and downloading bandwidth of the user are greatly saved.

Description

technical field [0001] The invention relates to a data transmission device, a processing system and a method of a smart charging pile, and is particularly suitable for use in a mobile smart charging pile. Background technique [0002] With the popularity of electric vehicles, more and more students choose to travel by electric vehicles in colleges and universities, and such a large number of electric vehicles are facing the problem of charging. charging position. However, the problem with this solution is that most of the current charging piles only have the single function of charging, and cannot perform a good battery state estimation on the charged battery, such as: the remaining service life of the battery, the estimated charging time, etc. Etc., also can not allow the user to check the progress of charging and charging state in real time while waiting for charging, also can not check own history charging information simultaneously. The charging locations provided are ...

AI Technical Summary

Problems solved by technology

However, the problem with this solution is that most of the current charging piles only have the single function of charging, and cannot perform a good battery state estimation on the charged battery, such as: the remaining service life of the battery, the estimated charging time, etc. etc., users are not allowed to check the charging progress and charging status in real time while waiting for charging, nor can they check their own historical charging information

The charging locations provided are limited, and the charging piles have single functions, and users cannot grasp the charging progress in real time. They are often faced with the situation of grabbing and occupying places, resulting in the majority of students' electric vehicle charging needs still being unsatisfied.
