To provide a multi-battery control system and an electric vehicle in which a main battery manages an auxiliary battery.SOLUTION: In a multi-battery control system of an electric-assisted bicycle, a main battery module includes a main controller that controls a main battery so as to supply current to a motor module 20 of the electric-assisted bicycle and acquires a first state of charge (SoC) value of the main battery and a first battery temperature, and an auxiliary battery module having an auxiliary controller and an auxiliary battery. The main controller controls the auxiliary battery module by using a communication interface and communicating with the auxiliary controller. The auxiliary battery module selectively supplies the current to the motor module or charges the main battery, and the main controller also obtains a second SoC value of the auxiliary battery and a second battery temperature via the communication interface.SELECTED DRAWING: Figure 1A

    【課題】主電池が補助電池を管理する多電池制御システム及び電気自動車を提供する。【解決手段】電動補助自転車の多電池制御システムにおいて、主電池モジュールは、電動補助自転車のモータモジュール20に電流を供給するように主電池を制御し、主電池の第一の充電状態(SoC)値及び第一の電池温度を取得する主コントローラと、補助コントローラ及び補助電池を備える補助電池モジュールと、を備える。主コントローラは、通信インターフェースを利用して、補助コントローラと通信することで、補助電池モジュールを制御する。補助電池モジュールは、モータモジュールに電流を選択的に供給するか又は主電池を充電する、主コントローラはまた、通信インターフェースを介して補助電池の第二のSoC値及び第二の電池温度を取得する。【選択図】図1A
