Abstract

A rechargeable battery powered electric vehicle comprising an electric motor powered by a rechargeable storage battery in combination with a recharging station comprising extendible electrodes for supplying recharging power for the vehicle'"'"'s storage battery, said vehicle comprising a charging circuit connected to said battery with one lead grounded to the vehicle body and one lead connected to a selected portion of an outer surface of the vehicle, said extendible electrodes being positioned in a charging station to extend toward said vehicle with one electrode in contact with the grounded portion of the vehicle and another electrode in contact with the insulated surface connected to said vehicle battery whereby when the vehicle is within reach of the electrodes they make desired contact between the power station and the battery and when the vehicle is moved away from the electrodes the charging connection is broken.

Claims

1. A power source station comprising electrodes for supplying electric power for recharging rechargeable electric batteries in combination with a vehicle comprising a main body portion including at least one rechargeable electric battery comprising electrodes, characterized in that the power source station is fixed to holding means associated with vehicle parking means and comprises at least one pair of spaced electrodes movably extendible toward said parking means and said vehicle comprises at least one battery recharge circuit portion grounding one battery electrode to the main frame of the vehicle and another battery recharge circuit portion connecting another battery electrode to an insulated surface portion of the vehicle;

whereby when the vehicle is moved onto said parking space one of said power source electrodes will be urged into contact with said grounding portion of the vehicle frame and the other of said power source electrodes will be urged into contact with said insulated surface portion of the vehicle.

2. The combination as claimed in claim 1, in which the holding means is a portion of a structure normally above the parking space and the insulated surface portion of the vehicle is positioned at an upper surface of the vehicle.

3. The combination as claimed in claim 1 which comprises switching means in at least one of the battery recharge circuit portions to selectively maintain such circuit portion in an open condition.

4. The combination as claimed in claim 3, in which the switching means is comprised in circuit breaker means.

5. The combination as claimed in claim 2 which further comprises guide means attached to the power station 20 visible through a vehicle windshield for positioning the vehicle with relation to the power source station connected to the structure.

6. The combination as claimed in claim 1, in which the spaced, movably extendible electrodes are associated with springs.
