ABSTRACT:
A pair of discharge pipes interconnect outlet ports of a plurality of batteries such that the first discharge pipe interconnects the outlet ports of some of the batteries and the second discharge pipe interconnects the outlet ports of the remaining batteries. The discharge pipes have rear ends connected respectively to atmospheric discharge units and other ends connected by joint pipes. Since the rear ends of the discharge pipes are connected to the atmospheric discharge units, even if one of the discharge pipes is closed or blocked for some reason, a gas emitted from the batteries is discharged from the other discharge pipes and hence is prevented from being trapped in the batteries. Additional pairs of discharge pipes a employed in the same manner for an additional plurality of batteries. The atmospheric discharge units include a backfire check member or valve and/or baffles for inhibiting ignition of the gas emitted from the batteries.
