The invention discloses an electric vehicle battery equalization device cooperatively charged with a direct current charging pile. The electric vehicle battery equalization device comprises a controller, N equalization charging modules, N equalization switches, a communication interface and an equalization charging interface, wherein the controller is in bidirectional connection with each equalization charging module, each equalization switch and the communication interface, the equalization charging module is connected with the corresponding equalization switch, and all the equalization switches are connected with the equalization charging interface, the communication interface is connected with a communication module of a direct-current charging pile, and a direct-current charging pile control module obtains a control signal of the equalization device through a communication module and charges a battery pack on an electric vehicle by controlling the direct-current charging switch. Under the condition that a battery is unbalanced, the controller controls the quick charging module of the direct-current charging pile to charge and controls each branch of the equalizing charging module to charge and discharge so that the battery can be quickly charged, and the service life of the battery is greatly prolonged.
