Battery pack formed by parallel connection of a plurality of secondary battery cells

摘要: A battery pack formed by parallel connection of a plurality secondary cylindrical cells 21 includes cell group 20, first conductive member 30, second 40, pieces 50 and fuses 60. The two members 40 are disposed at the same side 20 to avoid increasing size pack. each integrally with portions 31, 41 for connecting terminal 32, 42 as power output terminals. Hence, no wiring is required between portion portion, which reduces possibility caused short circuit wire loosening. have portions, 51 electrically connected 31 30 52 being positive terminals 212 21. 60 leg 61 62 negative 213 casing (80, figure 8) may be used retain pack, protruding from top casing.
