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 (...
