Hello,
I just found out about TLP - a module to download with apt, which is a good utility for maintaining the laptop battery. You can set a minimum charge value, and a maximum charge value. But it is not sufficient for my use case. My question is - is there any utility I can use to discharge the battery WHILE connected to AC?
The reason behind this is: I want to use the solar power during the day to charge up the battery to 80 or 90% and then discharge the battery in the evening to 15-20%. Afterwards use AC power again. The solar energy during mid-day is cheaper and available in abundance.
On a big level with many computers this could make a good impact on the energy network, or am I wrong?
The ups has data output to my firewall/router via usb, which the baremetal servers all connect to via apcupsd. When the ups loses or regains AC power, it broadcasts a message to all of them and they’re each scripted to act accordingly: laptops run on their own batteries, vms migrate over to laptops, non-vital hardware shuts down, etc.
