A power integration system with motor drive and battery charging and discharging includes a motor (10), a power integration circuit (20), and a battery (30). The power integration circuit (20) includes an inverter (21) and a charger (22). The inverter (21) includes multi-phase bridge arms, and each bridge arm has an upper switch (Q1, Q3, Q5) and a lower switch (Q2, Q4, Q6). Each bridge arm is correspondingly coupled to each phase winding of the motor (10). The charger (22) includes a front-end DC conversion path (22A), and the upper switch (Q1, Q3, Q5) and the lower switch (Q2, Q4, Q6) of at least one bridge arm of the shared inverter (21). The battery (30) is coupled to the power integration circuit (20). The power integration circuit (20) receives a DC power provided by a DC power apparatus (40), and the charger (22) converts the DC power to charge the battery (30). The battery (30) provides the power required to drive the motor (10) by the inverter (21).
