Publication number: 20150086845Abstract: A battery module having first and second battery cells is provided. The first battery cell has a housing and first and second electrical terminals. The housing extends longitudinally along a first axis and vertically along a second axis. The housing has first, second, third and fourth ends. The first and second ends extend parallel to the first axis. The third and fourth ends extend parallel to the second axis. The first electrical terminal extends from the third end in a direction parallel to the first axis, and has first and second edges extending parallel to the first axis. The first edge is disposed closer to the first end than the second edge of the first electrical terminal. A distance from the second end of the housing to the second edge of the first electrical terminal is greater than a distance from the first end of the housing to the first edge of the first electrical terminal.Type: ApplicationFiled: October 10, 2013Publication date: March 26, 2015Applicant: LG Chem, Ltd.Inventors: Sung Kyun Chang, Juil Yum, Heekook Yang

Publication number: 20150079427Abstract: The present invention relates to a case system for lead batteries. The case system comprises of a one piece, essentially box shaped cell-housing part with at least 4 sidewalls enclosing an interior volume. At least one division plane divides said interior volume, such as to form a plurality of compartments. Each of the compartments is adapted for storing an electrical cell. The case system further comprises an access wall part with electrical conductor openings or terminal feed throughs and at least one fluid channel opening. Furthermore the case system comprises a closure wail part for sealing off said casing system. Each of the at least one division planes is essentially perpendicular to the same two opposite side walls of the essentially box shaped cell housing. The present invention further relates to a lead battery and a battery rack incorporating the above described advantageous case system.Type: ApplicationFiled: October 11, 2011Publication date: March 19, 2015Applicant: ZHEJIANG NARADA POWER SOURCE CO.
