  "textContent": "Disclosed are an electric vehicle and a power system and a motor controller for an electric vehicle. The power system for an electric vehicle comprises a power battery (10); a charge-discharge socket (20); a two-way DC/DC module (30); a drive control switch (40); a two-way DC/AC module (50); a motor control switch (60); a charge-discharge control module (70); and a controller module (80). The controller module (80) is connected to the drive control switch (40), the motor control switch (60) and the charge-discharge control module (70), and the controller module (80) is used for controlling the drive control switch (40), the motor control switch (60) and the charge-discharge control module (70) in accordance with the current operating mode of the power system. The power system can achieve high-power AC charging to an electric vehicle using a civil or industrial AC power grid so that users can perform a quick charge at a high efficiency anytime and anywhere. In addition, the applicable battery has a wide range of operating voltages, thereby saving space and costs.",
