Embodiment Construction

[0020] The present invention will be described in detail below with reference to specific embodiments.

[0021] Specifically, this embodiment provides a method of data collection based on a single battery cell, data intercommunication with the controller, and transmission to a handheld terminal (mobile phone, tablet) through wireless data transmission (Bluetooth, wifi). Through our own Android and IOS application software for data analysis, we can realize real-time data warning of vehicle speed, battery life, battery capacity, low voltage warning, temperature warning, current warning, and charging warning. And through the wireless network (3, 4G, WiFi hotspot) and the background cloud server to store data, analyze the user data, before there may be a problem, the after-sales service of the car factory will notify the user to go to the maintenance point for maintenance, and realize that if the battery is abnormal, An early warning will be provided on the handheld terminal, and ...

Abstract

The invention discloses a wireless data communication management system for an electric bicycle. The wireless data communication management system comprises an intelligent electric bicycle management module which comprises a data collecting unit and a control unit. The data collecting unit is used for collecting data of single battery cells of a battery pack and transmitting the data to the controller. The controller transmits the data to a mobile device terminal through a wireless data transmitting module. A data analyzing unit is arranged in the mobile device terminal, analyzes the data according to the transmitted data, and carries out real-time data early warning according to setting of speed, endurance, battery capacities, low-voltage early warning, temperature early warning, current early warning and charging early warning of the whole electric bicycle. The mobile device terminal carries out data storage with a backstage cloud server through a wireless network, when batteries are abnormal, early warning is achieved through the mobile device terminal, a user is reminded that the batteries are abnormal, and meanwhile early warning information is transmitted to bicycle factory after-sale terminal equipment.

Description

technical field [0001] The invention relates to a wireless data communication management system for electric bicycles. Background technique [0002] Lithium battery electric bicycles and other products currently in use cannot intuitively understand the parameters of electric vehicles, lithium battery status and other information. During use, due to the safety characteristics of lithium batteries and the difficulty of after-sales, safety accidents occur frequently. [0003] Existing lithium battery management solutions are based on simple protection against overcharge, overdischarge, and overcurrent of lithium batteries. Unable to communicate with the controller and background synchronization information. Based on the characteristics of lithium batteries (whether they are 18650 cells or polymer cells), if a certain cell is near the overdischarge point, there will be safety hazards if a large current is discharged at this time. This simple protection does not allow the user ...
