According to one embodiment, a unit includes battery modules each including an assembled battery including battery cells and a monitoring device, a BMU to communicate with the battery modules, a first drawer holding the battery module, a second drawer holding the BMU, and a housing containing the first drawer and the second drawer. The first and second drawers include first composite connectors secured to a side of the housing, which is almost orthogonal to a direction in which to insert the drawers into the housing. The housing has second composite connectors which mate with the first composite connectors, thereby to connect communication lines between the monitoring device and the BMU and the main-circuit lines between the assembled batteries of the battery modules. |

1. A battery unit comprising:
a plurality of battery modules each comprising an assembled battery including a plurality of battery cells and an assembled battery monitoring device configured to detect the temperature and voltage of each battery cell; a battery management device configured to communicate with the battery modules; a first drawer holding the battery module; a second drawer holding the battery management device; and a housing containing the first drawer and the second drawer,
wherein the first drawer and the second drawer comprise first composite connectors secured to a side opposed to a side of the housing, which is almost orthogonal to a direction in which to insert the drawers into the housing, and the housing has second composite connectors which mate with the first composite connectors when the first drawer and the second drawer are inserted into the housing, thereby to connect communication lines between the assembled battery monitoring device and the battery management device and main-circuit lines between the assembled batteries of the battery modules,wherein each first composite connector comprises an anode terminal electrically connected to the anode of the assembled battery, a cathode terminal electrically connected to the cathode of the assembled battery, a male first connector connected to the assembled battery monitoring device, and a first communications connector and a second communications connector arranged between the anode terminal and the cathode terminal; andwherein each second composite connector comprises an anode connecting part connected to the anode terminal, a cathode connecting part connected to the cathode terminal, a female second connector connected to the male first connector, and a third communications connector and a fourth communications connector arranged between the anode connecting part and the cathode connecting part connected to the first and second communications connectors, respectively. |
