The invention discloses a special electronic lock for an electric vehicle. The special electronic lock for the electric vehicle comprises a plastic outer box body and an airtight plastic inner box body. A cylindrical metal spring bolt and a driving assembly are arranged in the outer box body, wherein the cylindrical metal spring bolt is coated with a protective film. The protective film comprises, by weight, 0.2 part of zinc naphthenate, 8-9 parts of methacrylic acid-isocyanic acid-ethyl ester, 0.2 part of calcium sulfate, 0.1 part of talcum powder, 1-2 parts of tri-iso-cyanuric acid ester, 2-3 parts of styrene-acrylic emulsion, 1-2 parts of coconut oil-based trimethyl ammonium chloride and 2-3 parts of polyethylene glycol. The special electronic lock for the electric vehicle has a unique mechanical design and an electronic design; since the cylindrical metal spring bolt of the electronic lock is coated with the protective film, long-term use of the cylindrical metal spring bolt can be guaranteed, and the situation that unlocking and locking can not be achieved normally due to corroding and rusting of the cylindrical metal spring bolt is avoided.
