Motive power batteries

In Figure 1, the cutaway view of the automotive battery shows the components used in its constmction. An industrial motive power battery, shown in Figure 2 (2), is the type used for lift tmcks, trains, and mine haulage. Both types of batteries have the standard free electrolyte systems and operate only in the vertical position. Although a tubular positive lead—acid battery is shown for industrial appHcations, the dat plate battery constmction (Fig. 1) is also used in a comparable size. 

Motive power batteries are generally of higher quality than SLI batteries. Their most important characteristics are constant output voltage, high volumetric capacity at relatively low unit cost, good resistance to vibration and a long service life. Since electric motors used for motive power require...

TABLE 5.45 Typical Range of Ratings of Standard Motive Power Batteries... 

Traction or motive power batteries are made in many different sizes, limited only by the battery compartment size and the required electrical service. The basic rating unit is the positive-plate capacity, given in amp-hours at the 5- or 6-h rate. The 2-V cell in the traction batteries is grouped with 2 to 16 positive plates, or 5 to 33 positive and negative plates. Traction batteries are often assembled to have battery voltage in... 

Traction or motive-power batteries are made in many different sizes, limited only by the battery compartment size and the required electrical service. The basic rating unit is the positive-plate capacity, given in Ampere-hours at the 5- or 6-h rate. Table 23.14a lists the typical U.S. traction plate sizes using flat-pasted plates between 5 and 33 plates are used to assemble traction cells, as also shown in the table. Ratings of the cell are the product of the capacity of a single positive plate multiplied by the number of positive plates. The cells, in turn, are assembled in a variety of battery layouts, with typical voltage in 6-V increments (e.g., 6, 12, 18 to 96 V) resulting in almost 1000 battery sizes. Popular traction battery sizes are the 6-cell, 11-plates-per-cell, 75-Ah positive-plate (375-Ah cell) and the 6-cell, 13 plates-per-cell, 85-Ah positive-plate (510-Ah cell) batteries. Table 23.146 presents similar information on the tubular positive-plate batteries. 

Through a quirk of history in the development of motive power batteries throughout the world, a tubular positive plate is used in Europe while in the USA a flat plate is preferred. The basic differences are as follows. 

Motive power battery capacities are normally given at the 5 or 6h rate of discharge. This hypothetieal, eontinuous rate of discharge relates most elosely to the actual performance of an industrial truck stop-start operation over an 8 h shift. Ambient temperatures also affect the capacity of a baitery. At low temperatures the capacity is considerably reduced. 

This gives the total number of ampere hours consumed by the truck s motors. However, other factors must be considered before the ampere hour capacity of the battery or batteries required can be decided. To ascertain current values and duration of discharge for a motive power battery several factors must be considered ... 

Taper charging of lead-acid motive power batteries... 

Chloride Motive Power produce five basic ranges of motive power batteries, the Classic series (three ranges), monobloc batteries and cells in hard rubber cases. 

The lead-acid battery is very basic to material movement and handling. A lead-acid motive power battery is a portable source of energy supplying direct electrical current (DC) to electric powered vehicles. A battery is a device that stores energy in a chemical form and releases that energy on demand, from the operator, in an electrical form to an external load—such as a motor. The battery releases power by the reaction of the electrolyte (sulfuric acid and water) with the active material of positive and negative plates (electrodes) within the battery.
