The invention provides an electric vehicle inverter for controlling and driving multiple motors, which is applied to hub motors or wheel side motors for new energy automobile control, and comprises a central processing unit and more than two paths of driving circuits connected with the central processing unit, each path of driving circuit can be connected with a group of hub motors or wheel side motors, and the inverter is connected with more than two groups of hub motors or wheel side motors through more than two paths of driving circuits. According to the electric vehicle inverter for controlling and driving the multiple motors, the central processing unit and the two or more drive circuits connected with the central processing unit are arranged, one set of central processing unit can control two or more sets of motors at the same time, and compared with a plurality of sets of inverters for controlling and driving multiple sets of hub motors or wheel edge motors respectively, the number of the motors is reduced; the synchronous control performance is better, the inverter can receive control instructions of a plurality of motors at the same time, and the response speed and aging requirements of a motor control system are met.
