Can a unit be able to regenerate health/morale?

Units repair 15% of damage they have taken at day change, if stationed in territory you control. Aircraft will repair even in flight, as long as their base of operations is in territory you control. Naval units repair at sea.

You can also use gold to improve a unit's battle condition. You will find the the gold button immediately beside the unit's percentage condition on the left-hand side of the unit command pop-up box,

Fifteen percent of the existing damage to a unit's battle condition will be restored automatically at the time of the daily update.

For example, if a light tank brigade (20 hit points at 100% condition) has suffered 50% damage (or 10 hit points), its present condition is 50% (or 10 hit points). If, at the time of the daily update, the unit is located upon territory you control (either a core or captured province, but not on allied, neutral or enemy territory), its condition will automatically be restored 15% of the existing damage, in this example 1.5 hit points (15% of 10 hit points = 1.5).

As stated above, aircraft units in flight will also have their condition restored in the same manner, provided they are based at an air base in territory you control, but not an allied or neutral air base, or on an aircraft carrier.

Naval units will have their condition restored in the same manner, regardless of location.

Does this answer your question?

There is no periodic healing throughout the day. It will come in one lump sum immediately upon day change.
