Supercapacitor module and supercapacitor core set for engine cold start

Abstract

The present invention discloses a super capacitor module for engine cold start and a super capacitor core. The super capacitor module includes a super capacitor core, fastening sleeves, a DC / DC converter, an external terminal and a housing. Super capacitor monomers of the super capacitor module are arranged in a plurality of rows and columns and the polarities of the super capacitor monomers in the adjacent rows and the adjacent columns are opposite to each other. Two super capacitor monomers in adjacent rows are connected in series through the lateral bus bar, and the vertical bus bar is used to realize the series connection of two super capacitor monomers in adjacent columns. The above structure is convenient for the super capacitor monomers to be connected in series and reduces the space occupied by the super capacitor module; the fastening sleeves clamp the super capacitor core from the front and rear sides of the super capacitor module, and the plurality of super capacitor monomers are matched with a plurality of single mounting portion respectively, in order to achieve clamping and fastening of the super capacitor monomers; and the buckle fastening is adopted to tightly lock the fastening sleeves on both sides, and the heat radiation groove is arranged to effectively cool the DC / DC converter mounted therein.

Description

technical field [0001] The invention relates to a starting power supply for an automobile, in particular to a supercapacitor module and a supercapacitor core set for engine cold start. Background technique [0002] At present, traditional batteries are mostly used as starting power for automobile engines, but due to low temperature environment, the viscosity of lubricating oil increases, the discharge characteristics of traditional batteries and the performance of fuel atomization deteriorate, making it difficult to start the engine (especially for diesel engines). In cold regions, fire preheating and other methods are usually used to start the engine with the battery. However, this starting method takes a long time, has low efficiency, and poor starting stability. inconvenient. [0003] Due to the good low-temperature characteristics of supercapacitors, supercapacitor modules are used instead of batteries as automobile starting devices. For example, Chinese Patent No. CN20...
