Four-wheel drive electrified vehicle with charging system utilizing motor and multiple inverters

An electrified vehicle comprising:

• a battery;
• a first motor;
• a first inverter connected to the battery and the first motor and including a plurality of first switching elements;
• a second motor;
• a second inverter connected to the battery and the second motor and including a plurality of second switching elements;
• a third inverter including a plurality of third switching elements;
• a first changeover switch including a plurality of fourth switching elements;
• a charging switch configured to selectively connect a neutral point of the first motor or a neutral point of the second motor to a charging power input stage;
• and
• a controller configured to control the charging switch to connect the charging power input stage to the neutral point of the first motor or the neutral point of the second motor in response to charging the battery with power input through the charging power input stage,
• wherein the first motor includes a plurality of first windings, a first end of each first winding connected to the first inverter,
• wherein the second motor includes a plurality of second windings, a first end of each second winding connected to the second inverter,
• wherein the third inverter is connected to a second end of each first winding,
• wherein a first end of each fourth switching element is connected to the second end of each first winding and second ends of the fourth switching elements are interconnected,
• wherein the first changeover switch provides the neutral point of the first motor in response that the plurality of fourth switch elements are turned on,
• wherein the charging switch includes a first state in which the charging power input stage is connected to the second ends of the first changeover switch and a second state in which the charging power input stage is connected to the neutral point of the second motor, and
• wherein the controller is further configured to control switching between the first state and the second state based on at least either temperature of the plurality of first switching elements or temperature of the plurality of second switching elements.
