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 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 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.

A battery pack is provided in which the battery pack itself can recognize a determination of a full charge, which is made by a charger, without using a communication line. A battery pack is provided with a secondary battery, current measurement means for measuring a charging current for charging the secondary battery, and a control circuit which receives an output signal from the current measurement means. The control circuit determines that the secondary battery is fully charged when a reduction rate of the charging current in a unit time exceeds a predetermined value.

A method for brand identification of an electric vehicle to a charging station includes connecting a plug of the charging station to a socket of the electric vehicle, receiving a control pilot signal at the socket from the charging station, terminating the control pilot signal in a variable resistance in the electric vehicle, and toggling the variable resistance in a vehicle pattern that transitions between two charging state resistances. The charging station detects the vehicle pattern and maps the vehicle pattern to a vehicle brand of the electric vehicle.
