The embodiment of the invention discloses a monitoring system for a power battery pack of an electric vehicle and the electric vehicle. The monitoring system comprises a power battery pack used for supplying power to a power supply module and an external electric vehicle; the power supply module is used for converting high voltage of the power battery pack into low voltage to provide required operation voltage for the monitoring circuit; the monitoring circuit is used for collecting state data and temperature information of the power battery pack, monitoring various fault alarms, performing external communication and program burning, and controlling on and off of a charging switch and a discharging switch of the power battery pack; and the display module is used for displaying the state data, the temperature information and various fault alarms in real time. Through the method and the device, the problems of frequent battery failure, low safety and shortened service life caused by the fact that the power battery pack of the electric vehicle cannot be effectively monitored in related technologies are solved, and the technical effects of effectively monitoring the running state of the power battery pack of the electric vehicle, reducing the battery failure rate, improving the battery safety and prolonging the service life are achieved.
