A partial battery pack structure includes a battery group, heat transfer plates, and a radiator, and is formed by stacking layers. Each layer arranges cylindrical batteries in parallel in a plane. The batteries in adjacent layers have alignment pitches shifted by a half pitch from each other. Each heat transfer plate contacts side surfaces of the batteries on both surfaces of the heat transfer plates, is formed by a heat transfer corrugated plate member, and extends through a gap between the batteries along an alignment direction of the cylindrical batteries in the layers in the plane intersecting center axis lines of the cylindrical batteries, a first intersection direction intersecting the alignment direction or a second intersection direction intersecting the alignment direction and the first intersection direction. The radiator is on a side of the battery group and connects with each heat transfer plate. Each battery contacts two or more heat transfer plates.

A vehicle driving apparatus includes a first motor, a second motor, and a planetary mechanism, and obtains a driving force by combining motive forces obtained from the first motor and the second motor by a planetary gear of the planetary mechanism. The vehicle driving apparatus includes at least one of a design value and a control quantity in which a frequency ratio between a sound generated by a rotation of the first motor and a sound generated by a rotation of the second motor satisfies a reduction condition of dissonance.

A storage battery module rental system includes a storage battery module prepared in each providing point that is dispersedly distributed and that can be rented to a user, an acquisition unit configured to acquire individual information of a plurality of the users and module information from the storage battery module, the user being a rentee candidate of the storage battery module, a determining unit configured to determine an incentive given for renting the storage battery module based on the individual information and the module information in such a way that the incentive could differ for each user; and a notifying unit configured to notify the user of the incentive determined by the determining unit for each of the users.
