Vehicle and recording medium

A recording medium storing a computer program applied to a vehicle drive power storage device comprising a power battery pack and at least two capacity battery packs comprising a first capacity battery pack and a second capacity battery pack, the power battery pack and the at least two capacity battery packs being installed in a vehicle and coupled in parallel, the at least two capacity battery packs having a higher capacity and lower power than the power battery pack, the second capacity battery pack being configured to have at least a smaller capacity than the first capacity battery pack and exclusively supply electric power to the power battery pack without supplying electric power to a load, the computer program causing one or more processors to perform processing comprising:

• acquiring one or both of a velocity and an acceleration of the vehicle;
• preferentially supplying electric power from the power battery pack to the load when the vehicle accelerates;
• and
• when the velocity of the vehicle is constant, exclusively supplying electric power from the second capacity battery pack to the power battery pack without supplying electric power from the second capacity battery pack to the load, concurrently with supplying electric power from the first capacity battery pack to the load.

A vehicle comprising:

• a vehicle drive power storage device comprising a power battery pack and at least two capacity battery packs comprising a first capacity battery pack and a second capacity battery pack, the power battery pack and the at least two capacity battery packs being coupled in parallel, the at least two capacity battery packs having a higher capacity and lower power than the power battery pack;
• a switch mechanism configured to switch a coupling state of the vehicle drive power storage device;
• circuitry configured to control charging and discharging of the vehicle drive power storage device via the switch mechanism;
• and
• a load configured to be driven and controlled by the circuitry, wherein
• the second capacity battery pack is configured to have at least a smaller capacity than the first capacity battery pack and exclusively supply electric power to the power battery pack without supplying electric power to the load, and
• the circuitry is configured to
• (a) preferentially supply electric power from the power battery pack to the load when the vehicle accelerates, and
• (b) when a velocity of the vehicle is constant, exclusively supply electric power from the second capacity battery pack to the power battery pack without supplying electric power from the second capacity battery pack to the load, concurrently with supplying electric power from the first capacity battery pack to the load.
