UPS Plus is a new generation of UPS power management module. It is an improved version of the original UPS prototype. It has been fixed the bug that UPS could not charge and automatically power off during work time. It can not only perform good battery power management, but also provide stable voltage output and RTC functions. At the same time,it support for FCP, AFC, SFCP fast charge protocol, support BC1.2 charging protocol, support battery terminal current/voltage monitoring and support two-way monitoring of charge and discharge. It can provide programmable PVD function. Power Voltage Detector (PVD) can be used to detect if batteries voltage is below or above configured voltage. Once this function has been enabled, it will monitoring your batteries voltage, and you can control whether or not shut down Raspberry Pi via simple bash script or python script. This function will protect your batteries from damage caused by excessive discharge. It can provide Adjustable data sampling Rate. This function allows you to adjust the data sampling rate so that you can get more detailed battery information and also it will consume some power. The data sampling information can communicate with the upper computer device through the I2C protocol. UPS Plus supports the OTA firmware upgrade function. Once there is a new firmware update, it is very convenient for you to upgrade firmware for UPS Plus. The firmware upgrade can be completed only by connecting to the Internet,and execute a python script. Support battery temperature monitoring and power-down memory function. UPS Plus can be set to automatically start the Raspberry Pi after the external power comes on. The programmable shutdown and forced restart function will provide you with a remote power-off restart management method. That means you don’t need to go Unplug the power cable or press the power button to cut off the power again. You can set the program to disconnect the power supply after a few seconds after the Raspberry Pi is shut down properly. And you can also reconnect the power supply after a forced power failure to achieve a remote power-off and restart operation. Once it was setting up, you don't need to press power button to boot up your device which is very suitable for smart home application scenarios.
Battery Type.
The board has contacts for connecting an additional battery. I have a LiFePo4 battery. Is there enough voltage to operate the device? 2.7 - Critical voltage. 2.9 - minimum voltage 3.2 - normal voltage 3.7 - Maximum
Will the board work if all batteries are disconnected from it?
PS
It would be very good. If you would describe in detail the purpose of all registers. And also indicated which ones can be changed, and which ones are read-only. Maybe even examples. Because they raise a lot of questions.
For example, I needed to read the current/voltage/power values from the INA219, but I found their addresses on the bus myself (upsplus.py file). There was no information anywhere on how to read data from the INA219.
Also interesting are the resistance values of the current shunts.
You made an excellent device, it remains to make detailed documentation for it =))
Thanks !
