A support for securing a battery pack in a vehicle wherein the battery pack includes a plurality of batteries bound together between two end plates having threaded mounting studs affixed thereto and projecting outwardly therefrom. The support includes a horizontal tray having an upstanding peripheral rim, a retainer flange projecting outwardly from the rim along one side of the tray, an upstanding mounting plate on the side of the tray opposite the retainer flange, and a retainer bar positioned above the retainer flange and appropriately secured thereto. The upstanding plate and retainer bar have apertures for receiving the studs on the battery pack.

Battery tray for electric vehicle

A low-profile and versatile battery-retaining assembly used to secure a plurality of batteries for an electric vehicle. The batteries are arranged in close proximity to one another in a generally rectangular matrix of two or more and each has recessed hold-down portions located on opposite lower edges. A perimeter frame extends about the battery arrangement and includes vertical and horizontal edge portions. Elongated retainer members extend between the batteries, each having enlarged portions which project into the recessed hold-down portions of the batteries. The elongated retainer members engage the frame with their ends extending into elongated slots which permits self adjustment with respect to the position relative the frame ends. This automatically accommodates variations in battery dimension.

Battery clamping and retention

A solenoid operated valve is installed in the fuel supply line of an internal combustion engine and is effective to interrupt the flow of fuel to the engine while the operating solenoid thereof is energized. A normally closed contact pair of an electrical relay which is energized when the engine is in the normal cranking mode is connected in series in the energizing circuit of the operating solenoid of the solenoid operated valve. A holding circuit for the operating coil of the relay is provided and includes at least a normally open contact pair of the relay and circuitry responsive to the operating mode of the engine effective to interrupt the holding circuit while the engine is in the not running mode.
