PCBA software and hardware technology system for shared rechargeable battery
First of all, the shared rechargeable PCBA must first be networked; that there are many ways of networking: Bluetooth, WiFi, etc.
Second, its core function is charging, then there is to have battery control technology (its own battery), charging protection (its own charging), discharge protection (charge your phone), if he does not come with a battery, it is directly a multi-export “transformer ° , not designed for battery control unit
Third: it wants the user to scan the code to pay in order to charge. Then the charger must also have the so-called intelligent ability, intelligent is nothing more than this hardware has MCU. To achieve its base payment amount to determine the charging time such a function. It does not need much good mcu, ordinary pic microcontroller are enough. It can be controlled in such a way that the structure: smart charger and the server is connected. And there is already an agreed communication protocol between them.
For example, the server sends 7e0118007e to the charger. Indicating that the charger’s 01 port can be charged for 1800 seconds (30 minutes). The smart charger receives this command and opens the 01 port to charge for half an hour. As to why the server side sends this command, it can be sufficient to send a message to the server side when the user sweeps the code and pays for it. So the approximate process is: the user sweeps the code and pays -) the server side identifies the target charger and port and sends the command -)
