Either the battery is defective or macOS is corrupted somehow. If you have the time, do a clean install of MacOS or if you use Time Machine, revert to a period prior to the problem. Other than that, you’ll have to make a Genius Bar appointment with the nearest Apple Store to have them look into the matter.
