摘要:
The present invention relates to a electrode stacking method, wherein electrodes are stacked in such a manner that the electrodes are disposed to face each other on both sides of a separation layer to which predetermined tension force is applied along the longitudinal direction of said separation layer, and the electrode assembly is turned so that another separation layer is formed outside the electrodes. According to the rechargeable lithium ion batteries in accordance with the present invention, the electrode stack in which the arrangement of anode electrodes and cathode electrodes is not disordered because uniform stress is applied to the entire battery and the separation layer maintains a constant tension force can be fabricated. Accordingly, the lifespan of a rechargeable lithium ion battery can be increased, and the input and output characteristic of the battery can be improved.

An apparatus and a method for detecting a vehicle location in a navigation system are provided. A travel angle difference and lateral and longitudinal inclinations of the vehicle are used to accurately detect the vehicle location if a vehicle location is estimated using detection signals from a sensor unit installed on a vehicle. If a value of DOP (Dilution of Positioning) of a navigation message received by a GPS (Global Positioning System) receiver is equal to or greater than a predetermined threshold, reference vehicle location information is set using vehicle location information just previously map-matched and the detection signals from the sensor unit. The vehicle location is detected using the set reference vehicle location information and the detection signals from the sensor unit.

The present invention relates to a method for detecting a map matching position of a vehicle in a navigation system, wherein coordinates of a current vehicle location are obtained from navigation messages received by a GPS receiver using a general line equation for obtaining an intersection point between an arbitrary line and a perpendicular line drawn from an arbitrary point to the line, and the current vehicle location is matched to coordinates found through orthogonal projection on a link on a digital map closest to the obtained coordinates of the current vehicle location. The current vehicle location is detected from the navigation messages received by the GPS receiver, the detected current vehicle location is matched on the digital map to obtain coordinates P0 of the current vehicle location, the digital map is searched to find a road link closest to the obtained coordinates P0 of the current vehicle location, coordinates P1 and P2 of both end points of the searched road link are obtained, the orientation of line P1P2 defined by the coordinates P1 and P2 of the obtained road link is checked on the digital map, coordinates P of an intersection point of a perpendicular line drawn from the obtained coordinates P0 to line P1P2 are obtained, and the current vehicle location is matched to the obtained coordinates P of the intersection point.
