The invention discloses an intelligent instrument of an electric vehicle. The intelligent instrument comprises a high-speed change-over switch, the acquisition module is electrically connected with the high-speed change-over switch, and the high-speed change-over switch is electrically connected with the motor temperature sensor and the controller temperature measurement circuit; wherein the motor temperature sensor is disconnected with the controller temperature measurement circuit, the acquisition module transmits an analog voltage signal to the controller temperature measurement circuit, acquires a voltage signal of the motor temperature sensor and analyzes the voltage signal into temperature, the high-speed change-over switch rapidly returns to a connection state, and the motor temperature sensor is disconnected with the controller temperature measurement circuit. The motor temperature sensor is reconnected with the controller temperature measuring circuit, and data measured by the motor temperature sensor are transmitted to the controller in real time. According to the invention, the model limit of the original controller of the electric vehicle can be ignored, and the temperature signal can be dynamically, reliably, quickly and losslessly acquired.
