Abstract
In a power output apparatus of the invention, a battery 36 is constructed by a lithium ion battery satisfying a first requirement of Sb/Pm2max>0.09 (m.sup.2/kW) as a relation of a total electrode area Sb of the battery to a rated output (maximum output) Pm2max of a motor MG2 in power operation and a second requirement of Sb/(|Pm1min+Pm2min|)>0.04 (m.sup.2/kW) as a relation of the total electrode area Sb of the battery to a rated output Pm1min of a motor MG1 in regenerative operation and a rated output Pm2min of the motor in regenerative operation. The lithium ion battery satisfying the first requirement and the second requirement ensures sufficient exertion of the drive characteristics of the motor MG2 and the power generation characteristics of both the motors MG1 and MG2.
