A regeneration system for an exhaust gas cleaning device disposed in an exhaust emission path of an internal combustion engine includes an exhaust gas cleaning honeycomb filter and a heating device for the filter, wherein the filter is a checkered SiC honeycomb filter having a given cell structure, and the heating device is a heater or a glow plug when using a fuel containing fuel additive. Particularly, the disclosure may control at least one of a lamp light color, a lamp blink pattern, and a sound pattern according to the battery charge state information such that a user can recognize the battery charge state away from the electric vehicle through hearing andor vision. Patterns are formed on the substrate along the path along which the printer head moves. Complex objects are analyzed using features in a distance transform map to identify a) nodule parts and b) vessels that are attached to or pass through the nodule parts. In the environment, the film is substantially resistant, in the near term, to biodegradation and natural, physical degradation due to weathering and exposure. The positive active material contains Na in an amount of 900 ppm or more and 16000 ppm or less, or K in an amount of 1200 ppm or more and 18000 ppm or less.
