A management device includes an information acquirer configured to acquire battery information on a usage state of a secondary battery mounted in a vehicle and information on a user from the vehicle, a first feature deriver configured to derive a first feature indicating a state of the secondary battery based on a result obtained by applying the battery information to a battery state detection model that identifies the state of the secondary battery, a second feature deriver configured to derive a second feature indicating characteristics of the user based on the information on the user, and a selector configured to select a battery suitable for the user based on a result obtained by inputting the first feature and the second feature to a matching model that outputs a result showing compatibility between the user and a battery based on the first feature and the second feature.

A vehicle control apparatus includes a determination processor and a regeneration controller. During traveling in a first travel mode, the determination processor determines a timing at which a regenerative braking force based on a motor regenerative force is to be increased under the condition that an accelerator-off operation period is equal to or less than a predetermined period. During traveling in a second travel mode, the determination processor refrains from determining the timing at which the regenerative braking force is to be increased under the sole condition that the accelerator-off operation period is equal to or less than the predetermined period. The regeneration controller performs control that increases the motor regenerative force as the determination processor determines the timing at which the regenerative braking force is to be increased.
