POWER OUTPUT SYSTEM

摘要

A power output system for outputting power to a load (10) includes: an energy storage device (30), for storing electric energy and outputting the electric energy to the load (10); and a control assembly (20), connected with the energy storage device (30) to control the power outputted from the energy storage device (30) to the load (10). The control assembly (20) includes a control device (21) which is used for detecting the remaining capacity of the energy storage device (30) and decreasing the power consumption of the load (10) when the remaining capacity of the energy storage device (30) is lower than a preset threshold. The system can effectively save the power of the energy storage device (30) and thus prolong the operation time of the load (10).
