How does the EV tax credit work? I pay over 7500 in income tax but do not owe an additional 7500 in liabilities at the EOY. would the 7500 credit reduce my taxable income

i am just trying to find out if i Can take advantage of the credit or not since i know its a nonrefundable credit making me worried that I would only be able to take full advantage if i owed and additional 7500 at the EOY.
