A system of controlling backup power of a lithium iron phosphate battery for a vehicle contains: the lithium iron phosphate (LiFePO4) battery module, a boost module, and a supercapacitor module which are parallelly connected with an electric control device of the vehicle. A first switch electrically is connected with a negative electrode of the electric control device and a negative electrode of the supercapacitor module of the vehicle, a second switch is electrically connected with a negative input electrode and a negative output electrode of the boost module, and a third switch is electrically connected with a positive electrode of the LiFePO4 battery module and a positive input electrode of the boost module. The system further contains a backup control module including a microprocessor configured to direct, control, order, and manage a detection unit, a controlling unit, and a Bluetooth module.
