    摘要： An electric automobile and a discharging device thereof. The discharging device comprises: an alternating current charging port (110); a charging connection device (120), configured to transfer, other electric automobiles, an alternating current output from the alternating current charging port; an instrument (130), configured to, upon receiving a trigger signal, send a discharging preparation instruction; a controller (140), communicating with the instrument (130), and configured to, after receiving the discharging preparation instruction, detect whether the charging connection device (120) is connected to the alternating current charging port (110), and if yes, send a Pulse Width Modulation (PWM) wave and switch to an external discharging mode; a battery manager (150), communicating with the controller (140), and configured to, after the controller (140) switches to the external discharging mode, control actuation of an external discharging loop in a high-voltage distribution cabinet of the electric automobile; and a power battery (160), configured to provide a direct current through the external discharging loop in the high-voltage distribution cabinet. The discharging device can charges an electric automobile without electricity, so as to solve the problem that the electric automobile cannot run because the battery power is used up on the halfway.

    摘要： The present disclosure discloses a vehicle and a method and an apparatus for unlocking a vehicle. The vehicle includes a plurality of Bluetooth modules, and the method includes the following steps: respectively obtaining a received signal strength indicator value corresponding to each of the Bluetooth modules; obtaining a distance between a terminal and the vehicle and a position of the terminal according to each of the received signal strength indicator values; determining, according to the distance between the terminal and the vehicle and the position of the terminal, whether the terminal is in a safe unlocking area and whether the vehicle meets a safe unlocking condition; and if it is determined that the terminal is in the safe unlocking area and the vehicle meets the safe unlocking condition, sending a vehicle unlocking instruction to a body control module of the vehicle, so that the body control module controls, according to the vehicle unlocking instruction, the vehicle to be unlocked. Therefore, according to the method, it can be accurately determined whether the terminal is in the safe unlocking area according to the received signal strength indicator values of the plurality of Bluetooth modules, greatly increasing accuracy and safety of vehicle unlocking.
