Abstract: An in-track charging system for charging the batteries of ceiling-mounted patient lifts includes a spring-biased pin assembly integrated with a movable truck and one or more rail-mounted charging stations. The truck-mounted assembly includes multiple spring-biased brass pins having upper ends extending upward from a top surface of the truck and lower ends terminating inside the main body of the truck. A wiring cable electrically connects the lower ends of the pins with a battery to be charged. Insulated bushings surround the spring-biased pins to prevent electrical short circuiting to the body of the truck. Each rail-mounted charging station includes a pair of insulated conductive plates that are joined to the inner surface of the upper horizontal cross-piece of the rail using conductive screws and nuts. To prevent electrical short circuiting to the rail insulator bushings are placed around the screws. Wires are connected to the ends of the screws and terminate at a battery charging unit.

Abstract: An electric vehicle assembly circuit connected to a battery of an electric vehicle for charging the vehicle batteries during operation and thereby increasing the distance the vehicle is able to travel between battery charges. The vehicle batteries are divided into first, second, third and fourth sets of batteries. The electric vehicle assembly circuit includes a first processor connected to the first set of batteries, a first controller connected to receive power from said first processor and an alternator. A device is connected between the first controller and the alternator for driving the alternator. A second controller is connected to the alternator for charging the second and third sets of batteries during operation of the vehicle. A first converter connected to said alternator for providing a constant charge to the first set of batteries. A first relay is positioned between the first converter and the lights and horn of the vehicle for providing a constant power to the lights and horn.
