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?
