BATTERY BLOCK AND SECONDARY BATTERY MODULE |
摘要 |
The purpose of the present invention is to provide a battery block capable of reducing stress acting on a connection portion due to thermal expansion/contraction or size error. A battery block (40) according to the present invention includes: a plurality of conductive members (191) arranged along side surfaces (114) of a holding case (111) and electrically connecting corresponding battery cells (101); voltage detection boards (201, 202) disposed opposite the side surfaces (114) of the holding case (111) and detecting the voltage of the battery cells (101); and a plurality of voltage detection terminals (204) respectively electrically connected to a plurality of conductive members (192) disposed on the voltage detection boards (201, 202). In the voltage detection terminals (204), a securing portion (221) secured to the voltage detection boards (201, 202) and a connection portion (231) connected to the conductive members (192) are disposed along an arranged direction, with a bend portion (241) which is elastically deformable in at least the arranged direction disposed between the securing portion (221) and the connection portion (231). |
