  The holographic quantum entanglement entropy for an infinite strip region of
the boundary for the field theory dual to charged black holes in ${\cal
A}dS_{3+1}$ is investigated. In this framework we elucidate the low and high
temperature behavior of the entanglement entropy pertaining to various limits
of the black hole charge. In the low temperature regime we establish a first
law of entanglement thermodynamics for the boundary field theory.
