Immediately after the ignition switch is turned on (S11), a check is performed in S12-S15 to determine whether the replacement high-energy battery is an authorized, legitimate product. In S12 the identification code (ID) of the high-energy battery is compared with identification codes (IDs) for legitimate high-energy batteries. When it is determined in S13 that the identification code (ID) matches, then in S14 a flag BFLAG is set to 1 to indicate that the replacement high-energy battery is a legitimate product; when it is determined in S13 that the identification code (ID) does not match, then in S15 the flag BFLAG is set to 0 to indicate that the replacement high-energy battery is an unauthorized, illegitimate product. Subsequently, control is moved from S11 to S16, and if the BFLAG = 1, then in S17 the motor output is controlled normally, but if the BFLAG = 0, then in S18 the motor output is restricted such that vehicle speed is limited to 20 km/h. Thus, when an unauthorized battery has been used as a replacement the driver is alerted quickly and driving is permitted, enabling the driver to perform a replacement with an authorized battery. |
