Abstract
A device for filling or topping-up batteries, including a trolley, a reservoir for acid or distilled water, and conduits for connection to the inlet and the outlet ends of a series of filler devices, one on each battery cell. At the end of the series a conduit is connected to a sump on a trolley. A pump draws liquid by siphon from the reservoir through the filling devices to the sump. A level responsive switch in the sump is used for terminating the filling operation which can be performed automatically by connecting the conduits and switching on the equipment. A timer and an air valve ensure that all the liquid is sucked out of the line after the cells have been filled before the pump is switched off. Automatic connections connect the inlet and outlet to exhaust through explosion minimizing vents once the conduits have been disconnected.
Claims14
A battery filler comprising:
- a reservoir,
- conduit means for leading fluid from the reservoir to one or more cells of a battery,
- a filling device for each of said cells which prevents further liquid entering each of said cells when a predetermined level has been reached,
- a pump coupled to the conduit means downstream of said cells for drawing fluid by suction from the reservoir to said cells,
- a sump in the conduit means between said cells and the pump,
- a level-responsive switch in the sump arranged to initiate emptying of the conduit means by the pump when the liquid in the sump reaches a predetermined level,
- a drain valve from the sump closed during filling and open after filling is completed in response to operation of said level-responsive switch,
- a trolley upon which the conduit means, the pump, the sump, said level-responsive switch and said drain valve are mounted, and
- means enabling the trolley to be moved from battery to battery.
