Why is my battery not increasing in energy while plugged in to energy charger?

Check that the power outlet works.

Make sure the charging adapter is plugged in.

You may need to reset the laptop's SMC.

Depending on the Age of the computer, some aspects from the above links, may or may not apply to your computer.

A feature introduced into Big Sur & Monterey was to preserve the number of Full Battery Cycles - there was an Algorithm coded into the macOS. It is perfectly Normal for Big Sur , Monterey to Pause / Suspend charging the battery beyond 80% and hold it at that level. One can nudge / over-ride this by clicking the Battery Icon on Desktop Top Bar and allow charging beyond 80%. From observations, it will Pause / Suspend again once reading 90%. Same procedure to over-ride and will charge to 100%

And is user profile accurate MacBook Pro 14″, macOS 12.2

If yes, the current version of Monterey is 12.4 as of May 16, 2022

A Time Machine Backup would be suggested Before updating to 12.4

Yeah, there's always that. 😁

Glad you got it sorted out.
