<p>Electric vehicles usually inherit a chassis of a pressed steel construction from a conventional vehicle design. This imposes a substantial weight penalty on the vehicle. A chassis element for a vehicle is therefore provided, formed of an outer skin material 22, an inner core material 24 enveloped by the outer skin material, and at least one array of aligned fibres 38, and comprising a restraint or enclosure 26 for an electrical battery 28 and fixing points 36 for attaching the element to a chassis. There can be multiple arrays of aligned fibres, preferably disposed at a transverse angle relative to each other of less than 90°. Three arrays are particularly preferred, which can be disposed relative to each other at an angle of 60°. The fibres can be disposed within the skin material. The application also relates to a vehicle comprising a chassis, an electric motor, a chassis element as set out above, and electrical connections from the battery to the motor, wherein the chassis element is attached to the chassis via removable fixings.</p> |
