ABSTRACT:
A system for supplying fluid to a battery, a vacuum source, a vehicle, a combination, a method for supplying fluid to a battery and a method of charging a battery. The fluid supply system supplies fluid to a battery in a vehicle, the vehicle including a frame supporting the battery, the battery including a battery cell, fluid being transmittable to the battery cell. The system is defined as including a hydraulic circuit connecting the battery to a tank. The hydraulic circuit is defined as including an inlet conduit connectable to tank, an outlet conduit connectable to the battery cell, and a vacuum source connectable to the battery cell and to the tank. The vacuum source is defined as including a pump having a pump inlet conduit connectable to the tank, and a pump outlet, and a venturi having a first inlet connectable to the pump outlet, a second inlet connectable to the battery cell, and a venturi outlet is connectable to the tank. The pump is operable to cause flow through the venturi, flow through the venturi causing fluid flow from the tank and through the battery cell.
