1. An electric vehicle battery recharging system comprising:
- an audible indicator; and
a controller;
wherein the controller is configured to actuate the audible indicator in response to a voltage of a battery system rising a predetermined amount from an initial voltage value after recharging is initiated so as to provide audible confirmation to a recharging operator that the battery system is being recharged, wherein the predetermined amount is based on a predetermined time period of between 5 and 20 seconds for the voltage to rise from the initial voltage value by the predetermined amount.

Abstract
An electric vehicle battery recharging system is disclosed that is capable of generating an audible sound to indicate that the battery system of the vehicle is being recharged. The system includes an audible indicator that is connected or otherwise associated with a controller. The controller is configured to actuate the audible indicator in response to a voltage or current of a battery system rising a predetermined amount after recharging is initiated so as to provide audible confirmation to a recharging operator that the battery system is being recharged.

8. An electric vehicle comprising:
-
a rechargeable battery; a connection port for connection to a recharging power cable; an audible indicator; and a controller configured to actuate the audible indicator in response to a predetermined increase in a voltage value of the rechargeable battery from an initial voltage value after the recharging power cable has been attached to the vehicle connection port to indicate the rechargeable battery is recharging, wherein the predetermined increase in the voltage value is based on a predetermined time period of between 5 and 20 seconds for the predetermined increase in the voltage value from the initial voltage value to occur. - View Dependent Claims (9, 10, 11)

12. An electric vehicle battery recharging system comprising:
-
a connection port operable to receive a recharging power cable; a first controller connected with said connection port for generating a charging current that is applied to a battery system, wherein said controller includes an application that takes an initial reading associated with said battery system; and an audible indicator associated with said controller, wherein said controller includes a second application that monitors a reading associated with said battery system until said reading reaches a predetermined threshold above said initial reading, wherein the predetermined threshold is based on a predetermined time period of between 5 and 20 seconds for the reading to reach the predetermined threshold from the initial reading, wherein once said reading reaches said predetermined threshold said controller sends a signal to said audible indicator causing said audible indicator to generate an audible sound indicating the battery system is charging. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
