  "textContent": "A battery electric vehicle includes: a traction motor; an inverter driving the motor; a first battery; an electric device running on electric power from the first battery; a detachable portable second battery; a first connecting and disconnecting device connecting and disconnecting a power line connected to the inverter and the first battery to and from each other; a second connecting and disconnecting device connecting and disconnecting the power line and the second battery to and from each other; and a control device controlling the first connecting and disconnecting device and the second connecting and disconnecting device. When a system startup instruction is given, the control device controls the first and second connecting and disconnecting devices so that the second battery is preferentially connected to the power line over the first battery when a temperature of the second battery is within an allowable temperature range of the second battery.",
