Electric bicycle intelligent charging system based on NB-IOT and working method thereof

Abstract

The invention discloses an electric bicycle intelligent charging system based on NB-IOT. The system comprises a user terminal, a cloud platform server and a plurality of direct current charging piles, and is characterized in that each direct current charging pile is provided with a first NB-IOT communication module which is in communication connection with the cloud platform server; the direct current charging pile is further provided with a control system; a man-machine interaction module is used for receiving a charging instruction of the cloud platform server; a microprocessor is used for controlling the operation of the direct current charging pile; an electrode detection module is used for detecting the polarity of a storage battery connected with the direct current charging pile; a power supply module is used for providing dynamic output voltage and current for charging the storage battery; a power supply module charges the storage battery by adopting a self-adjusting three-stage charging method; and an electric energy output control module is used for controlling on-off of a storage battery charging circuit. The polarity of the storage battery can be detected to avoid damage to the storage battery, a self-adjusting three-stage charging method is adopted to charge the storage battery, damage to the storage battery caused by charging when the storage battery is over-discharged is further avoided, and a safe, convenient and efficient charging system is provided for a user.

Description

technical field [0001] The invention belongs to the technical field of charging piles, and in particular relates to an NB-IOT-based intelligent charging system for electric bicycles and a working method thereof. Background technique [0002] As a means of transportation for short-distance travel, electric bicycles are widely used in people's daily lives. At present, the battery power supply of electric bicycles mainly adopts two forms of lead-acid battery and lithium-ion battery, which must be realized by a charging device. [0003] However, there are currently problems in the industry such as lack of knowledge about the safe use of chargers, which lead to non-compliance behaviors such as charging for a long time, using inferior chargers, wiring without permission, and irregular electricity consumption during use. There are more and more safety accidents in the battery charging process. [0004] Among them, the existing electric bicycles generally use three (36V) or four (...

Problems solved by technology

However, because the plugging and storage of the charger is very cumbersome, and even the safety charging accidents caused by the quality problem of the charger itself still happen from time to time
