Abstract

The invention discloses a battery thermal management control method. The battery thermal management control method comprises the steps of detecting the temperature of a battery, and cooling the battery when the temperature of the battery is higher than a preset cooling range value; and heating the battery when the temperature of the battery is lower than a preset heating temperature value. According to the method, heating and cooling to the battery in different environments can be realized, so that the environment adaptive capacity of the battery can be reinforced, the endurance of the battery can be improved, and the service life of the battery can be prolonged, so that client requirement can be satisfied, and core competitiveness of an electric vehicle can be improved. The invention also discloses a battery thermal management system and the electric vehicle adopting the same.

Description

technical field [0001] The invention relates to the technical field of vehicle batteries, in particular to a battery thermal management control method and system and an electric vehicle. Background technique [0002] With the depletion of oil resources and the aggravation of environmental pollution, the development of electric vehicles has attracted more and more attention. However, some problems in the manufacturing stage of electric vehicles have seriously restricted the development of electric vehicles. [0003] Electric vehicles use batteries as the power source, and the batteries must work within a suitable temperature range to ensure high efficiency and long life. When the ambient temperature is too low, the batteries cannot achieve the discharge power of the entire vehicle, resulting in a limited vehicle speed. The heating system cannot achieve rapid temperature rise, so it cannot meet the heating needs of the passenger compartment; when the ambient temperature is too...
