Abstract

Official abstract text for this publication.

An electric motor vehicle of the present invention is characterized in that the electric motor vehicle includes: a high-output assembled battery; a high-capacity assembled battery having a larger capacity and a smaller output than those of the high-output assembled battery; and an inverter, and the electric motor vehicle is equipped with a PCU that transmits and receives electric power to and from the high-output assembled battery and the high-capacity assembled battery, a first wiring that connects the high-output assembled battery to the PCU, and a second wiring that connects the high-capacity assembled battery to the PCU, and is shorter than the first wiring.

First claim

Opening claim text (preview).

What is claimed is: 1 . An electric motor vehicle comprising: a high-output battery; a high-capacity battery having a larger capacity and a smaller output than a capacity and an output of the high-output battery; an electric power controller that includes an inverter, the electric power controller being configured to transmit and receive electric power to and from the high-output battery and the high-capacity battery; a first wiring that connects the high-output battery to the electric power controller; and a second wiring that connects the high-capacity battery to the electric power controller, the second wiring being shorter than the first wiring. 2 . The electric motor vehicle according to claim 1 , wherein in electric power transmitted and received by the electric power controller, a percentage of electric power transmitted and received between the electric power controller and the high-capacity battery is greater than a percentage of electric power transmitted and received between the electric power controller and the high-output battery. 3 . The electric motor vehicle according to claim 1 , wherein a location of the high-capacity battery is closer to the electric power controller than a location of the high-output battery is. 4 . The electric motor vehicle according to claim 3 , wherein the electric power controller, the high-capacity battery, and the high-output battery are disposed in this order in one direction. 5 . The electric motor vehicle according to claim 1 , wherein the high-capacity battery and the high-output battery are disposed under a floor panel of the vehicle while the high-capacity battery and the high-output battery are housed in an identical case. 6 . The electric motor vehicle according to claim 5 , wherein the electric power controller is disposed more frontward than a vehicle cabin, and the high-capacity battery is disposed more frontward than the high-output battery in the case. 7 . A battery pack including batteries of two or more types, the battery pack comprising: a case; a high-output battery housed in the case; a high-capacity battery that is housed in the case, the high-capacity battery having a larger capacity and a smaller output than a capacity and an output of the high-output battery; a connection terminal electrically connected to an electric power controller disposed outside the battery pack; a first internal wiring that connects the high-output battery to the connection terminal; and a second internal wiring that connects the high-capacity battery to the connection terminal, the second internal wiring being shorter than the first internal wiring.
