Claim 4:
5. A battery control method that is performed by a computer of a battery control device, the battery control method comprising:
performing a first identification including acquiring an identification voltage which is output according to a type of a battery from the battery and identifying the type of the battery based on the acquired identification voltage;
performing a second identification including acquiring identification information for identifying the type of the battery from the battery and identifying the type of the battery based on the acquired identification information;
estimating the type of the battery based on an identification result of the first identification and an identification result of the second identification, including:
estimating the type identified by the first identification and the second identification to be the estimated type of the battery when the identification result of the first identification and the identification result of the second identification match, and
estimating the type of the battery to be unclear when the identification result of the first identification and the identification result of the second identification do not match;

determining whether the battery has been replace;
storing the type of a battery to be controlled; and
prohibiting execution of a first operation including an operation of transitioning from manual driving to automated driving when the estimated type of the battery does not match the stored type of the battery to be controlled,
wherein the method further comprises performing the second identification for identifying the type of a battery that replaced the battery when (1) the estimated type of the battery matches a type of the battery that is stored and (2) the battery has been determined to have been replaced.
