Abstract

The invention provides an energy control system, method and device and an automobile, and relates to the technical field of automobiles. The energy control system comprises a condenser arranged in a passenger compartment of an electric vehicle; a first heat exchanger which can exchange heat with a liquid cooling system of a power battery; a second heat exchanger which is connected with a motor cooling loop through a liquid cooling pipeline; and an energy recovery component and a first liquid cooling heater, wherein, the energy recovery component, the first liquid cooling heater, the condenserand the first heat exchanger form a liquid cooling circulation loop, and heat on the second heat exchanger can be transmitted to the liquid cooling circulation loop through the energy recovery component; a heating controller of the first liquid cooling heater is connected with the motor controller in parallel, and a selector switch is arranged on a circuit connected in parallel. By collecting waste heat of the motor cooling loop and braking energy which cannot be recycled by a power battery, the effects of assisting a passenger compartment and the power battery in heating and improving the energy utilization efficiency of a whole vehicle are achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an energy control system, method, device and automobile. Background technique [0002] With the development of science and technology, automobiles have become an indispensable means of transportation in people's daily life; as fuel is a non-renewable resource, in order to reduce the consumption of fuel, more and more automobile manufacturers are gradually devoting themselves to the research of pure electric vehicles and Production. [0003] Electric vehicles use power batteries to provide energy for the vehicle dynamics system and air conditioning system. In low temperature environments, the mileage of battery vehicles is attenuated by 30% to 50%. The reasons for the serious attenuation of electric vehicle mileage are: 1. The discharge power is reduced; 2. The heating of the passenger compartment and the battery will consume most of the energy of the battery; 3. In a low-tem...
