11552490 · 2023-01-10 · ·

A charging cable has a current sensor, a charging state indicator and logic circuitry to operate the indicator based on detected levels of current flow to a chargeable device. If the sensor detects current is below a low threshold, the logic circuitry operates the indicator to indicate that the cable is not connected to any chargeable device. If the sensor detects current at or above a higher threshold, the logic circuitry operates the indicator to provide a perceptible output indicating that the cable is connected to the chargeable device and the current is charging the battery. If the sensor detects current at or above the low threshold but below the high threshold, the logic circuitry operates the indicator to provide a perceptible output indicating that the cable is connected to a chargeable device but is not charging the battery of the device, e.g. when the battery is, or is nearly, fully charged.
