Abstract: An inflator includes an inflator housing, a pressure sensor operable to generate a pressure signal related to an outlet pressure of the inflator, a motor within the inflator housing, a battery pack removably coupleable to the inflator housing, and a controller electrically coupled to the motor and the battery pack. The controller is configured to receive the pressure signal from the pressure sensor, determine a rate of pressurization change based on the pressure signal, determine a static pressure value based on the rate of pressurization change, and determine a motor time delay based on a target pressure value, the static pressure value, and the rate of pressurization change. The controller is also configured to generate a control signal when the motor time delay substantially equals zero. The control signal is operable to cause power to the motor to be turned off to stop a pressurization condition of the inflator.
