The invention discloses a full electric vehicle. The full electric vehicle comprises a key-free entry system, a whole vehicle controller, a power battery and a battery manager. The key-free entry system comprises a controller and an intelligent key. The controller sends secret key information when detecting a power-on key signal of the intelligent key. The whole vehicle controller authenticates the secret key information and sends a power-on forbidding signal when secret key information authentication fails. The battery manager forbids the power battery to output electric energy according to the power-on forbidding signal. The full electric vehicle can be prevented from being stolen and is safer. The invention further discloses a power-on control method of the full electric vehicle.
