On top of that there's more for EV owners, assuming the EV has a higher value that a comparable ICE car. That's because the car registration calculation is ad valorem (higher tax for higher value car).
Alabama is not the most Woke state. Many liberal states give tax breaks for buying an EV, allow EV to use HOV lanes for one person, and provide free electricity to recharge. These states wouldn’t dream of charging EV more.
Also, the manufacturers are going to price in larger profits on ICE cars to offset losses on EV cars.
