According to one embodiment, a battery unit (10) includes a plurality of battery modules (MDL) each including an assembled battery (1) including a plurality of battery cells and an assembled battery monitoring device (2) configured to detect the temperature and voltage of each battery cell, a battery management device (16) configured to communicate with the battery modules (MDL), a first drawer (100) holding the battery module (MDL), a second drawer (110) holding the battery management device (16), and a housing (10) containing the first drawer (100) and the second drawer (110). The first drawer (100) and the second drawer (110) comprise first composite connectors (CNA) secured to a side of the housing (10), which is almost orthogonal to a direction in which to insert the drawers (100, 110) into the housing (10), and the housing (10) has second composite connectors (CNB) which mate with the first composite connectors (CNA) when the first drawer (100) and the second drawer (110) are inserted into the housing (10), thereby to connect communication lines between the assembled battery monitoring device (2) and the battery management device (16) and the main-circuit lines between the assembled batteries (1) of the battery modules (MDL). |
