The invention discloses a high-voltage distribution cabinet of an electric vehicle. The cabinet comprises a cabinet body and a cabinet cover. A concave cavity is formed in the cabinet body and internally provided with a circuit board, a current detector, a fuse, thermistors, a relay, a copper bar and a wire. A plurality of electrically connected connectors are arranged on the outer wall of the cabinet body, a boss is circumferentially arranged on the end face of an opening of the concave cavity of the cabinet body, the cabinet cover is provided with a groove matched with the boss in a clamped mode, and a rubber ring is disposed in the groove. By means of the connectors, electricity allocated into the high-voltage distribution cabinet is transmitted to various electric appliances, the protection grade of the cabinet body can be improved, and a good fool-proof function can be achieved. The positive temperature thermistor and the negative temperature thermistor can effectively prevent the situation that a circuit is too hot and accordingly resistors and elements are burnt, and the safety coefficient of equipment is improved.
