Title: WIRELESS ELECTRIC ENERGY TRANSMISSION-BASED POWER MANAGEMENT SYSTEM AND METHOD
Abstract:
A wireless electric energy transmission-based power management system and method. The system comprises a BMS main control box, a vehicle control system, a ground control system, and a plurality of groups of charging circuits. Each group of charging circuits comprises a specific number of battery boxes, ground transmitting circuits connected to a power grid and used for transmitting energy, and vehicle receiving circuits used for receiving the energy and supplying power to the battery boxes in the group. The vehicle receiving circuits are respectively connected to various battery boxes in the group for detecting the charging states of various battery boxes in the group in real time during charging and transmitting same to BMS sub-control boxes of the BMS main control box; the BMS sub-control boxes are connected to the BMS main control box. The battery boxes in each charging circuit are connected in series and then supply power to a load. By means of the power management system, a plurality of groups of charging circuits charges the battery pack of the whole vehicle so as to reduce the voltage in the charging circuits, such that the risk in system development and experiment processes and the requirements on devices are reduced, and the system costs are low.
