Power supply managing and protecting system

The invention relates to the field of wireless charging and management for a power supply, and particularly to a power supply managing and protecting system. The power supply managing and protecting system comprises a battery, charging piles and a wireless charging device which matches the charging piles. The wireless charging device is mounted on a garbage collecting and conveying vehicle. The charging piles are arranged in a distributed manner according to an urban road condition. The wireless charging device comprises a plurality of secondary coils, a coil control switch, a storage unit, a magnetic board, a control chip, a monitoring unit, a cooling device and temperature acquisition unit. According to the power supply managing and protecting system, battery charging in operation of a vehicle is realized through the charging piles which are arranged in a distributed manner and the wireless charging device; and furthermore the monitoring unit which is arranged in the system can perform data acquisition on the voltage, the current and the electric charge quantity for realizing management and protection for wireless charging to the battery, thereby greatly improving the operation efficiency of the vehicle.
