Hello and welcome to JustAnswer!
Your fault code is missing a digit.
If it is P0562 that sets when battery voltage falls too low. This could be the battery itself or a draw or possibly a charging system issue, but if it wasn't charging then there should be more codes set and you'd be seeing the voltmeter drop to zero while driving.
If it's P0563 this code sets when battery voltage is too high. This could be the battery, alternator, or this will also set when the key is turned on with a battery charger hooked up.
