The invention discloses an electric vehicle, a power battery charging control method, a power battery temperature maintaining control method and a power battery management system. It can be ensured that a power battery works safely under the condition that the environment temperature is extremely low or extremely high. The power battery charging control method comprises the following steps that the power battery is electrically separated from a charging loop under the condition that the temperature of the power battery is not within a temperature range allowing charging; after the power battery is electrically separated from the charging loop, the electricity of a charging pile is used for providing constant direct-current high-voltage electricity required by work for a battery thermal management system; real-time temperature information of the power battery is received, and the battery thermal management system is controlled to adjust the temperature of the power battery based on thereal-time temperature information; and the power battery is connected into the charging loop under the condition that the temperature of the power battery is within the temperature range allowing charging.
