Backpack-Type Power Supply

摘要

A backpack-type power supply includes: a plurality of cell units (52) each configured of a plurality of secondary battery cell (51); a case (12) configured to accommodate the cell units and having first and second contacts; and a harness (13) attached to the case, characterized by including; first connecting means (581, 571) for electrically connecting the first contact and a positive terminal of each cell unit to form a first electrical path therebetween; and second connecting means (572, 582) for electrically connecting the second contact and a negative terminal of each cell unit to form a second electrical path therebetween, each first electrical path and each second electrical path forming a total electrical path having a total resistance for each cell unit, the total resistance of each total electrical path being adjusted such that heat distribution is substantially uniform over the plurality of cell units in the case.

1. A backpack-type power supply comprising:
a plurality of cell units each configured of a plurality of secondary battery cells connected in series; a case configured to accommodate the plurality of cell units therein, the case having a first contact and a second contact each electrically connected to each of the plurality of cell units; a harness attached to the case and adapted to be worn on a user's back;
a first connector configured to electrically connect the first contact and a positive terminal of each cell unit to form a first electrical path therebetween, each first electrical path having a first resistance; anda second connector configured to electrically connect the second contact and a negative terminal of each cell unit to form a second electrical path therebetween, each second electrical path having a second resistance, each first electrical path and each second electrical path forming a total electrical path for each of the cell units, the total electrical path for each cell unit having a total resistance, the total resistance of each total electrical path being adjusted such that heat distribution is substantially uniform over the plurality of cell units in the case.
