The structure of shared powerbank
The shared powerbank divided into three parts. Station, Powerbank, Customer-end APP and the back-end server.
In terms of hardware, powerbank station adopts low-power MCU solution to realize intelligent management of shared powerbank. The MCU connects with the back-end server. Between them there is an agreed communication protocol . For example, after the consumer returns the powerbank, the server will send instructions to the station to charge the usage. The equipment can support domestic 4G IoT card for telecommunication. In order to ensure the signal unlocked.
Regarding the safety of the powerbank, battery supports 5V output short circuit protection, internal overcurrent and short circuit protection. Also the rated input of the powerbank battery can automatically balance the charging current according to the input 5V charging capacity. Besides, the rated output of the power bank battery can be balanced according to the load capacity.
The most important part of the shared powerbank project is the software system. Merchants get powerbank information, return information and time synchronization information through the back-end server. In order to prevent theft. The slots of the device will locked according to the backstage big data. And the battery will not bounced out. Firmware of the device can realize remote OTA for software maintenance and upgrade. Through the customer end APP developed by this back-end server, consumers can quickly locate the nearest empty station for return.
