The shared rechargeable PCBA development function

In people’s daily life, the one that accompanies them most of the time is the cell phone. If the cell phone runs out of battery, it is very inconvenient for them. Because nowadays people don’t bring cash to go out, and a cell phone completes all daily operations. Including cell phone payment. So if your phone is out of battery. It will be very difficult to go out. So shared charging can let people charge at any time in their lives.

The shared rechargeable PCBA development function is below.

1,Dual USB output port, can charge iPad/iPhone at the same time. Also can charge 2 cell phones or digital devices at the same time.

2, 5000mAh high-capacity lithium polymer cells, equivalent to 5-6 cell phone batteries. Although It can used for cell phone standby 30 days.

3, Durable, charge and discharge cycle times ≥ 500 times.

4,Intelligent control, microcomputer intelligent pro-measurement and display of power.

5,Single key shuttle, one technical key can achieve all functional operations.

6,Automatic hibernation, using intelligent microcontroller control, non-working state automatically hibernate to prevent power loss of Refrigeration.

7.Multifunctional, suitable for iPad/iPhone, cell phone, MP3, MP4, GPS and other digital products.

8, Plug and play, using USB port power supply things out, plug in the data cable can be achieved on the go, charging at any time.

9,Value sharing, It do not need to arch with a variety of chargers. Randomly included adapters can be charged for various brands of cell phones.

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 -)
