Uuder Body for Electric Vehicle

Under consisting of a vehicle body of the electric automobile body in particular, a battery is divided mountable electric vehicle underbody is provided for. The electric vehicle underbody for has been provided to allow for selective mounting Multi-section of the battery, and dividing the battery receiving part that is provided as part of the underbody and the under body portion associated to said battery receiving part is provided to other parts of the underbody include or bottom part; And, doedoe associated with the bottom portion, can be provided ever provide ever increasing the rigidity of the underbody is implemented for each light-weight rigid or reinforcing parts, including a reinforced underbody having at least a portion of the extension portion. Of course, preferably, the under body portion, there is provided a reinforced underbody part including at least a portion of the extension portion, would be provided to the bottom portion, and dividing the battery receiving part. According to the present invention, while being as composed of an electric vehicle, the vehicle body at the same time to make excellent the bending and torsional rigidity and, front and rear, and side impact performance, in particular, the present invention provides a light-weight structure, optionally with Multi-section of the battery and by enabling the replacement, by making it in accordance with the vehicle running environment, to reduce the weight with the battery, it is possible to obtain an improved effect that enables ultimately reducing vehicle maintenance costs.
