Abstract
An engine ignition flag system may include an engine, a starter motor coupled to turn the engine, a battery configured to power the starter motor, a sensor coupled to the engine and configured to provide sensor data indicating a speed of the engine, a user interface and a controller operatively coupled to the sensor. The controller is configured to receive, from the sensor, the sensor data corresponding to a measurement period, determine, based the speed of the engine during the measurement period, a condition of the battery, and, control the user interface to provide a notification indicating the condition of the battery.
Claims20
An engine ignition flag system, comprising:
- an engine;
- a starter motor coupled to start the engine;
- a battery configured to power the starter motor;
- a sensor coupled to the engine and configured to provide sensor data indicating a speed of the engine;
- a user interface;
- and
- a controller operatively coupled to the sensor and configured to:
- receive, from the sensor, the sensor data corresponding to a measurement period;
- determine, based the speed of the engine during the measurement period, a condition of the battery;
- and
- control the user interface to provide a notification indicating the condition of the battery.
A method of determining a battery condition, comprising:
- controlling a battery to operate a starter motor to start an engine;
- measuring, using a sensor, an engine property of the engine while the starter motor is operated;
- and
- determining, based on the engine property, a condition of the battery.
A method of displaying a battery condition, comprising:
- powering, by a battery, a starter motor to turn an engine;
- measuring, with a sensor, an engine speed of the engine for a measurement period;
- determining the battery condition of the battery by:
- calculating a rate of change of the engine speed during the measurement period based on the engine speed;
- and
- determining whether the engine speed reached a threshold speed during the measurement period;
- and
- providing a notification to a display indicating the battery condition.
