In order to meet the requirement of energy support, energy system and energy efficiency about combat vehicles, energy architecture has been studied. On the basis of analyzing the energy requirement about modern combat vehicles, types of energy-load and the functions of load are classified about combat vehicles, in view of the existing problems in the energy distribution mode, a combat vehicle energy system with intelligent management and comprehensive integration is constructed, by energy distribution of combining area energy control with grid energy control, and using middleware technology construction energy management software, the suggestion is put forward to realize the localization of energy system about combat vehicles. The research has practical significance to improving the continuous combat capability of the entire joint combat force.
