Cable assembly for multiple batteries
View Patent ↗A vehicle battery cable has a plurality of subsidiary or daughter cables where the subsidiary cables have the same length and gauge and exhibit closely matched resistance. The vehicle battery cable connects a plurality of batteries in parallel to a load in a way that each battery carries the same proportion of the load as every other battery.
1. An electrical cable comprising:
a first section having a main conductor sheathed in an insulation layer; and
a subsidiary section formed at an end of the first section and depending from the first section, the subsidiary section including four subsidiary conductors, the subsidiary conductors being sheathed in insulation layers, one end of the four subsidiary conductors being electrically connected to the main conductor, and each of the four subsidiary conductors being physically configured to be of like resistance wherein the subsidiary conductors have like length and gauge.
2. An electrical cable as set forth in claim 1 , comprising:
a second end section depending from the first section comprising a length of unsheathed conductor.
3. An electrical power system comprising:
a plurality of batteries each having terminals of first and second polarities;
a first plurality of electrical conductors attached to terminals of the first polarity from the plurality of batteries; and
the first plurality of conductors meeting at a juncture at ends distal to the terminals of the first polarity of the plurality of batteries to form a first joint conductor electrically connecting the plurality of batteries in parallel to electrical components of the electrical power system, the plurality of conductors having like length and gauge between the terminals of the first polarity and the juncture.
4. An electrical power system as set forth in claim 3 , further comprising:
a second plurality of electrical conductors attached to terminals of the second polarity from the plurality of batteries; and
the second plurality of electrical conductors meeting at a juncture at ends distal to the terminals of the second polarity to form a second joint conductor, the second plurality of electrical conductors having like length and gauge between the terminals and the juncture.
5. An electrical power system as set forth in claim 4 , further comprising:
a vehicle starter motor connected to the first and second joint conductors.
6. An electrical power system comprising:
a plurality of batteries;
a load; and
a connection system including conductors exhibiting closely matched resistance to one another connecting each of the plurality of batteries to the load in a parallel arrangement; wherein the connection system includes first and second battery cables, the battery cables including subsidiary cables extending along a portion of the length of the battery cables, the subsidiary cables having like length and gauge.
