Abstract

A capacitor-type power supply unit including: a positive bus to which a plurality of capacitor is connected in parallel at each positive-electrode terminal thereof with maintaining equal intervals therebetween, and extends in a parallel direction; and an negative bus to which the plurality of capacitor is connected in parallel, at each negative-electrode terminal thereof with maintaining equal intervals therebetween, and extends in the parallel direction, in which the positive bus has a positive-electrode-side external connection part that is set at a position (SD) separated from the positive-electrode first end by a range of 20% to 30% of the total length in the longitudinal direction thereof, and the negative bus has an negative-electrode-side external connection part that is set at a position (SD) separated from the negative-electrode second end by a range of 20% to 30% of the total length in the longitudinal direction thereof.

Dependent claims

A capacitor-type power supply unit in which a plurality of a first to nth electrical storage devices are connected in parallel, wherein n is an integer of 6 or greater, the capacitor-type power supply unit comprising:

a positive-electrode-side parallel connection conductor in which each positive-electrode terminal of the first to nth electrical storage devices is connected in sequence from one end to another end of the positive-electrode-side parallel connection conductor;
and
an negative-electrode-side parallel connection conductor in which each negative-electrode terminal of the first to nth electrical storage devices is connected in sequence from one end to another end of the negative-electrode-side parallel connection conductor,
wherein the positive-electrode-side parallel connection conductor has a positive-electrode-side external connection part that is set at a position separated from an end on a side of the first electrical storage device by a length corresponding to a resistance value in a range of 20% to 30% of a resistance value from the one end to the other end, and
wherein the negative-electrode-side parallel connection conductor has a negative-electrode-side external connection part that is set at a position separated from an end on a side of the nth electrical storage device by a length corresponding to a resistance value in a range of 20% to 30% of a resistance value from the one end to the other end.
