    The coherent perfect absorption phenomenon in cavity optomechanics system based on Bose-Einstein condensation(BEC) is investigated. The conditions of inducing coherent perfect absorption producing are elaborated, and the energy conversion is analyzed when coherent perfect absorption occurs in strong coupled BEC cavity optomechanics system. Coherent perfect absorption can be effectively modulated by controlling the pump field power. When coherent perfect absorption occurs, the input probe field energy is completely converted into the mechanical oscillator and cavity field energy without any transmission and reflection. Energy extraction can be realized by changing the cavity quality factor. The strong coupled BEC cavity optomechanics system provides a theoretical basis for potential applications based on coherent perfect absorption, such as transducers, modulators, and optical switches and so on.
