Heat management system and control method thereof, charging and battery replacing station

Abstract

The invention belongs to the technical field of heat management, in particular to a heat management system and a control method thereof, and a charging and battery replacing station. In order to solvethe problem of energy wastage during battery charging, the heat management system according to the present invention includes a coolant circulation device, the coolant circulating device includes a circulating line for circulating the coolant, a thermal management system for managing temperatures of a first target body and a second target body disposed in the circulation pipe, The thermal management system further includes a control unit capable of acquiring the temperature of the first target body and controlling the coolant circulation device according to the temperature of the first targetbody to adjust the flow path of the coolant in the circulation pipe, and thus adjust the order of the coolant passing through the first target body and the second target body. The invention can effectively utilize the heat generated by the first target main body or the second target main body, thereby avoiding the phenomena of waste of heat and large power consumption caused by the fixed flow direction of the coolant.

Description

technical field [0001] The invention belongs to the technical field of thermal management, and in particular relates to a thermal management system, a control method thereof, and a charging and swapping station. Background technique [0002] With the increase of the number of automobiles in our country, automobile emission pollution has become the main source of urban air pollution in our country. As a large energy consumer and a large greenhouse gas emitter, how can the automobile industry meet the growing demand for oil? How can you contribute to reducing CO2 emissions? The consulting report of the Chinese Academy of Engineering "The Vision of China's Petroleum Demand Battle Network and Alternative Strategy Research" gave a clear answer: "Among various alternatives to oil, the use of electricity alternatives can not only realize the diversification of energy sources for vehicles, but also eliminate the impact on vehicles. Environmental pollution. Vigorously developing ele...
