The invention discloses an ultra-low power consumption intelligent lock which comprises an intelligent door lock control system, the intelligent door lock control system comprises a front lock and a rear lock, the rear lock comprises a rear lock main control MCU, the rear lock main control MCU is connected with a door lock power supply system, and the door lock power supply system has a single battery power supply mode and a double battery power supply mode. Free switching is achieved by controlling a switch of a PMOS field effect power tube, when the rear lock master control MCU detects that the electric quantity of a main battery is lower than a set threshold value, a switching instruction is sent out, meanwhile, a low level is given to a PMOS grid electrode, the field effect tube is opened, a standby battery is switched to supply power to a lock control system, and the lock control system prompts that the electric quantity of a first battery is low when the rear lock master control MCU is powered on.
