This is a device for filling or topping-up batteries, for example, an assembly of batteries mounted in a vehicle for propulsion. It consists of a trolley (60) including a reservoir (42) for acid or distilled water, and lines (61) and (62) for connection to the inlet and the outlet ends (47) and (44) of a series of filler devices (16) one on each battery cell. At the end of the series the line (61) is connected to a sump (46) on a trolley, and a pump (49) draws liquid from the reservoir through the filling devices to the sump. A level responsive switch (56) in the sump is used for controlling termination of the filling operation which can be performed automatically by connecting the lines (61) and (62) and switching on the equipment. There is a timer (59) and an air valve (57) for ensuring that all the liquid is sucked out of the line after the cells have been filled before the pump is switched off. There are automatic connections (70) for connecting the inlet and outlet (47) and (44) to exhaust through explosion minimising vents (71) once the lines (61) and (62) have been disconnected. |
