Vehicle-mounted power management system

The car carry synthesis power management system is composed of a synthesis power box and a power distribution equipment. The synthesis power box is composed of an alternating current distribution module, a power supply module, a charge module, a linear manostat, an auxiliary power supply module, a display module, a control module, a double limiter. The power distribution equipment is composed of a direct current distribution module, a display module, a control module and an auxiliary power supply module, which realizes that a car silicon engine generator delivers the power to a specially used equipment and charges the storage battery through the double limiter, and an external power and a specially used engine generator can also deliver the power to the electrical equipment of car chassis and charge the car storage battery, the direct current distribution module of power distribution equipment has the functions of over-load protection, the protections of short circuit and over-current for all power supply parts, mutual independence of all power supply parts, and the system can display the working condition of the system, fault information and offer the protection function.
