Device and method for identifying virtual electricity state of power battery of electric vehicle

The invention discloses a device and a method for identifying a virtual electricity state of a power battery of an electric vehicle. The device comprises a host and an OBD vehicle-mounted terminal, and the OBD vehicle-mounted terminal comprises an OBD connector, an OBD decoding module, a micro-processing module and a data transmission module which are connected in sequence; the host comprises a data receiving module, a real-time vehicle condition collecting module, a vehicle condition storing and reading module, a virtual electricity recording and storing module and a virtual electricity state recognizing module; data transmission is carried out between the host and the OBD vehicle-mounted terminal through the data receiving module and the data transmission module; battery data are collected in real time, whether the battery has a virtual electricity state or not is automatically judged according to a virtual electricity recognition algorithm, and when virtual electricity appears, a virtual electricity record
