Standard event messages for Shutdown, power lost on Linux
Clash Royale CLAN TAG#URR8PPP
We are developing a small battery, based on capacitor, which can keep the machine ON for 2 minutes once the AC Power is lost.
We are going to write a Linux device driver for the module, it provides us with the status information like AC is connected or disconnected.
Is there any way for the Linux driver to send standard messages such as
- AC Power Lost
- AC Power restored
- Shutdown
All the applications registered for that event should get the message.

Suggest you look at APC forums.apc.com and what their driver does seismo.ethz.ch/static/linux/apc_usv.html .

Yes this must have already been solved: It is what every laptop does, your battery only differs in being smaller capacity, and hopefully having a longer life. You may not need to create a driver (this is preferable: as no need to install custom software), if you make the hardware comply with existing standards.
The driver will not send a message, but will send an event.
The driver should not send a shutdown, as this is up to the policy. It should send power lost, or power critical, the policy then will send a shutdown event.

No. Look at existing code, or better design the hardware to be compatible with a standard, so that existing drivers can be used.
