The present invention enables a battery to function efficiently. A vehicle travel system (10) is provided with: a travel motor generator (13) connected to a first battery (11) and a second battery (12) via relays; a power receiving unit (14) connected to the first battery (11) and the second battery (12) via a relay, and connected to an external power source (30); and a control device (15). The control device (15) is configured so as to charge the first battery (11) when the state of charge of the first battery (11) is lower than a predetermined SOC and so as to charge the second battery (12) when the state of charge of the first battery (11) is equal to or greater than the predetermined SOC when the power receiving unit (14) has been connected to the external power source (30). 本发明使电池高效地发挥功能。车辆行驶系统(10)具备：行驶用电动发电机(13)，分别经由继电器而与第一电池(11)和第二电池(12)连接；受电单元(14)，分别经由继电器而与第一电池(11)和第二电池(12)连接，并且与外部电源(30)连接；以及控制装置(15)。控制装置(15)构成为，在受电单元(14)已与外部电源(30)连接时，在第一电池(11)的充电状态比预先决定的SOC低时向第一电池(11)充电，并且在第一电池(11)的充电状态为预先决定的SOC以上时向第
