A battery module includes one or more batteries 21, 22-2n and a case 1 housing the batteries and having output terminals 3, 4, each output terminal being connected to a positive or negative electrode of the housed battery, the battery module further including means5 for turning on and off the connection between the output terminal and the positive or negative electrode of the battery. The means for turning on and off the connection may include a contact subjected to making and breaking operations and a screw 6 for making and breaking the contact, the screw having an insulator 7 at an interface with the contact. Alternatively a FFB (Fuse Free Breaker) switch (9, figure 4) may be used as a means for switching the battery output. |
