  • Patent number: 4042054
    Abstract: In a light electrically powered vehicle, a battery pack of two to six batteries is supported on the rear axle independently of bending forces on the frame. The resultant (1) lighter frame requirement and (2) reduced battery requirement together have a synergistic weight-saving effect. The complete battery pack is light enough to be readily removable rearwardly by direct lifting on a manually operated handtruck and is readily replaced. The ready removability and replaceability of the pack frees the vehicle from battery charging shut-downs, and enables a fleet of vehicles such as golf carts to be kept fully in operation by provision of a battery recharging facility, extra battery packs and a few handtrucks. The vehicles of the fleet can be easily stored or shipped vertically for space-saving since the batteries can be readily removed. Further space-saving is effected by temporarily replacing the battery packs in the vertically stored vehicles, the packs being placed in their normal horizontal position.
