  "textContent": "A charging system includes a motor, first/second inverters, a neutral point switching element, a power receiving terminal, a circuit selector, and a controller. The motor includes a plurality of stator coils. First ends of the stator coils are connected to the first inverter, and second ends of the stator coils are connected to the second inverter. The neutral point switching elements interconnect the second ends of the stator coils at neutral points. An external power source is connected to the power receiving terminal. The circuit selector switches a connection relationship between the first/second inverters, the power receiving terminal, and the neutral point. The controller controls the circuit selector so that a current flows from the external power source to the stator coil through the switching element having a small accumulated stress among the switching elements of the first/second inverters and the neutral point switching element.",
