AN ELECTRIC BATTERY POWERED HEAVY VEHICLE

摘要

An electric battery powered bus (10) having a massive replaceable battery (14) as its power plant. The battery (14) is mounted on chassis structure at the rear of the bus (10) which is provided with an opening at the rear through which the battery (14) can be withdrawn for recharging and replaced by a recharged battery (14). A major part of the battery (14) is above the chassis structure on which it is supported and extends laterally to either side so that it occupies a major part of the width of the bus (10). The suspension of the bus (10) is adjustable whereby the chassis structure is lowered on the wheels (12) to lower the battery (14) onto a trolley for withdrawal and a replacement battery installed in its place is raised by raising the chassis structure relative to the wheels (12).
