What are the components of an automotive battery grid?
Components of an automotive battery grid There have been many designs of grids adopted over the years based on the lattice principle. In this, the horizontal members are approximately half the thickness of the grid and half that of the rib cross section.
What is the difference between casting grids and molten alloys?
In contrast, casting a grid from the molten alloy did not require complicated or costly equipment, all trimmings could be returned to the lead alloy furnace and the moulds were not expensive to buy or difficult to make. Because of these attributes, casting grids has remained the main grid-making system.
Do automotive batteries have lead sulfate?
Automotive batteries are rarely deeply discharged and the amount of lead sulfate formed is a function of the depth-of-discharge and not the capacity rating. Less active material can be allowed in the design per ampere-hour than in a battery that is regularly subjected to deep discharges, such as a traction battery.
What is grid casting & how does it work?
The objective in grid casting is to maintain the mould temperature constant both from one cast to the next and throughout the working shift. The temperature of the mould, particularly the moving half, depends on the external heating source plus the heat transferred from the molten metal poured into the mould.
Can a negative grid be made from a melt?
The possibility to produce sized strip direct from the melt leads to cost reductions in producing strip, and the competitive manufacture of fabricated grids becomes possible. The use of other metals, such as aluminium and brass, heavily lead coated, has been proposed particularly for negative grids.
