Abstract

The invention relates to the technical field of energy management, and discloses a power supply management system and a power supply management method. According to the invention, the power supply management system comprises a controller, a target charging loop is determined through the controller according to a received control signal, the target charging loop comprises a fast charging loop and a slow charging loop, and then a to-be-charged device is charged through the target charging loop. The target charging loop is determined according to the received control signal, the charging loop in the current scene can be accurately obtained, and compared with an existing mode that power can only be supplied through a power grid or a battery, the corresponding charging mode can be determined according to the target charging loop, and the charging efficiency is improved. The to-be-charged device is charged through the quick charging loop or the slow charging loop, so that the to-be-charged device is charged while the to-be-charged device is ensured to work normally and continuously.

Description

technical field [0001] The invention relates to the technical field of energy management, in particular to a power supply management system and a power supply management method. Background technique [0002] For the equipment to be charged, real-time power supply is required to continue running. Taking electric excavators as an example, due to the high working power of electric excavators and relatively fixed scenarios, they usually use mains\battery time-sharing or simultaneous power supply mode. According to different power supply methods, it is divided into the following three types: single battery power supply, single grid power supply, and battery grid hybrid power supply. However, the above three methods not only increase the use cost of the excavator, but also limit the working range of the excavator to the length of the cable connected to the power grid, and reduce the sustainable working ability of the excavator. Therefore, how to realize the continuous operation o...
