The invention discloses a parking lot. The parking lot comprises parking spaces, a movable charging robot and a robot management system. The charging robot comprises a robot body, a travelling mechanism, an energy storage component and a control unit, wherein the travelling mechanism is used for driving the robot body to the electric vehicle parking position, the energy storage component is used for storing electric energy and charging an electric vehicle, and the control unit is used for receiving a control instruction and controlling travelling operation of the travelling mechanism and discharging of storage battery packs according to the control instruction so as to accomplish charging of the appointed electric vehicle. The control unit comprises a monitoring alarm unit. According to the parking lot, due to the fact that the movable charging robot is provided with the monitoring alarm unit, the movable charging robot is used for being on duty or going on night patrol when the movable charging robot does not conduct charging operation, and labor intensity of operators on duty in the parking lot is reduced; the hidden danger of accidents such as burglaries and fires is discovered in time, the accidents can be conveniently handled in time when happening, and expansion of the accidents is avoided.
