摘要

#CMT# #/CMT# The method involves arranging a series of energy storage cells (12) for electrically connecting the cell arresters (14) of the energy storage cells. The electrical interconnection elements (16) are produced by joining cell arresters together, and sliding butt joint fixing cap (20). The embossment portions are electrically connected with cell arresters in mutual engagement. #CMT# : #/CMT# An independent claim is included for energy storage cell. #CMT#USE : #/CMT# Method for manufacturing electrical energy storage unit of electrical energy-storage system such as traction battery used in electric vehicle and hybrid vehicle. #CMT#ADVANTAGE : #/CMT# The replacement of energy storage cells can be performed efficiently in simple manner. Overheat of the energy storage cells can be prevented. Hence, the electrical energy storage unit can be manufactured favorably with optimized design. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the electrical energy storage unit. 10 : Electrical energy storage unit 12 : Energy storage cell 14 : Cell arrester 16 : Electrical interconnection element 20 : Butt joint fixing cap.
