Abstract
This disclosure relates to an access cover detection circuit for an electrified vehicle component and a corresponding method. An exemplary component of an electrified vehicle includes an access cover configured to selectively open and close relative to the component, and a circuit configured to indicate whether the access cover is open. The circuit includes a light sensitive electronic component.
Claims12
A component of an electrified vehicle, comprising:
- an access cover configured to selectively open and close relative to the component;
- and
- a circuit configured to indicate whether the access cover is open, wherein the circuit includes a light sensitive electronic component,
- wherein the light sensitive electronic component is a light dependent resistor,
- wherein the circuit includes a transistor arranged in parallel with the light dependent resistor,
- wherein the transistor is configured to turn on such that a voltage output is detectable when the access cover is closed,
- wherein the transistor is configured to turn off such no voltage is detectable when the access cover is opened, and
- wherein the circuit includes a resistor in series with the light dependent resistor.
