Abstract

Battery apparatus for use in starting railroad locomotives includes a portable housing. A Lithium Iron Phosphate chemistry Lithium ion battery is carried within the housing. The battery has a positive output lead and a negative output lead accessible from the exterior of the housing. A low voltage and high voltage protection module is positioned within the housing and connected to the positive output lead and the negative output lead. The module is constructed to switch the battery into a “sleeping mode” when the battery voltage reaches a low voltage or a high voltage condition. Output terminals are mounted on an exterior surface of the housing in a location available to be connected to a locomotive by interconnecting cables. When the voltage protection module switches the battery into the “sleeping mode” a push button on the housing is used to reactivate the apparatus.

Claims

1. Battery apparatus for starting railroad locomotives comprising:

a portable housing;

a Lithium Iron Phosphate chemistry Lithium ion battery carried within the housing, the battery having a positive output lead and a negative output lead;

a low voltage and high voltage protection module positioned within the housing and connected to the positive output lead and the negative output lead, the module being constructed to switch the battery into a “

sleeping mode”

when the battery voltage reaches a low voltage condition or a high voltage condition; and

a pair of output terminals coupled to the positive output lead and the negative output lead, the output terminals mounted on an exterior surface of the housing in a location available to be connected to a locomotive by interconnecting cables.

2. Battery apparatus for starting railroad locomotives as claimed in claim 1 wherein the housing includes a cover for access to components carried within the housing and the pair of output terminals being mounted on the cover.

3. Battery apparatus for starting railroad locomotives as claimed in claim 1 wherein the Lithium ion battery is a single 64 volt Lithium ion battery unit.
