Electrical power management for distributed automotive system

Abstract

The electrical power management for distributed automotive system is proposed. The electrical power requirement is analyzed and the steady power source and electrical safe power source are independently proposed. Power supply channel with three-level current protection is designed to construct an electrical safe power supply which includes selective overload protection, fast short current protection and fuse backup protection. Prototype of electrical power management system is developed based on intelligent relay. The test result showed that the electrical management works well and the protection method is effective.
