    Abstract: A hybrid battery with a sodium anode is designed for use at a range of temperatures where the sodium is solid and where the sodium is molten. When the battery is at colder temperatures or when the vehicle is idle and needs to be “started,” the anode will be solid sodium metal. At the same time, the battery is designed such that, once the electric vehicle has been “started” and operated for a short period of time, heat is directed to the battery to melt the solid sodium anode into a molten form. In other words, the hybrid battery operates under temperature conditions where the sodium is solid and under temperature conditions where the sodium is molten.

  • Publication number: 20140342202
    Abstract: According to the present invention, a battery-cooling system for an electric vehicle is configured such that the interior of a battery case is divided into a plurality of rooms, each of which has a cell module assembly mounted therein. Thus, airflows among a plurality of cell module assemblies may not affect one another, and air passes independently from each cell module assembly to the other within each room, thereby achieving improved cooling performance due to the independent airflows. Further, discharge ducts for each room may have respective suction fans, thus enabling the independent discharge of air from each cell module assembly and achieving improved cooling performance.

  • Publication number: 20140338999
    Abstract: In a structure for mounting a battery pack on a vehicle, since a recess portion, into which a cross member is fitted, is formed on an upper face of a battery case so as to extend in a vehicle width direction, it is possible to mount the battery pack on a vehicle body without interfering with the cross member, and it is unnecessary to raise the position of the cross member or form a cutout in the cross member, thereby enabling a balance to be achieved between the capacity of a vehicle compartment and the strength of the cross member while ensuring a sufficient minimum ground clearance for the battery pack and preventing a battery from becoming wet. Furthermore, since the recess portion is formed on the upper face of the battery case, a cooling passage disposed beneath the battery is not narrowed, thus ensuring the battery cooling performance.
