Linux: How to use energy better in general by fine-tuning laptop battery?
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?

Plus cycling the battery like that will wear it out faster, and they're generally only rated for 500 or so cycles. The replacement cost would likely easily over come any savings.
