BATTERY CONTROL SYSTEM AND SADDLED VEHICLE

A battery control system 6 according to an embodiment controls charging/discharging of a nickel-metal hydride battery 40 having a hysteresis characteristic for a relationship between voltage and SOC. A microcontroller 61 selects one of a plurality of SOC use ranges depending on the condition of use, and controls the charging/discharging of the nickel-metal hydride battery 40 in accordance with the selected SOC use range. The microcontroller 61 determines whether the current SOC of the nickel-metal hydride battery 40 is equal to a predetermined SOC that corresponds to the lower limit of an SOC use range 130. When it is determined that the current SOC is equal to the predetermined SOC, information regarding the memory effect of the nickel-metal hydride battery 40 is obtained. The microcontroller 61 controls the discharging of the nickel-metal hydride battery 40 using the obtained information regarding the memory effect.
