Hello, sarada593.

Let's start off by checking the helpful steps in this article which can help with this issue: If your Mac battery won’t charge - Apple Support. Follow these steps:

1. "Reset the SMC: Reset the System Management Controller (SMC), which controls how your Mac manages power. If you have a Mac with Apple silicon, just restart your computer. For other Mac computers, see the Apple Support article How to reset the SMC of your Mac.
2. Get your Mac serviced: If the battery still won’t charge, your Mac may need to be serviced. Take your Mac to your local Apple Store or contact AppleCare. See Find how to service or repair your Mac."
