Abstract

The invention discloses a cooling circulation system for electric vehicles, and an electric vehicle with the cooling circulation system. The cooling circulation system of the electric vehicle comprises a driving motor, a power electronic unit, a first cooling branch, a second cooling branch, a third cooling branch, a first branch switching unit and a second branch switching unit. According to the cooling circulation system for electric vehicles, and the electric vehicle with the cooling circulation system, which are disclosed by the embodiment of the invention, the first branch switching unit and the second branch switching unit are arranged in the cooling circulation system, and the switching between the first branch switching unit and the second branch switching unit is controlled, so that the switching of cooling loops under different modes can be realized; only parts in a working state under a corresponding mode need to be cooled, and the cooling of all parts is not needed, so that unnecessary consumption is reduced; besides, a cooling pipeline is shortened, and the cooling flow is increased, so that the working efficiency of the cooling circulation system is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular, to a cooling cycle system for an electric vehicle and an electric vehicle having the same. Background technique [0002] At present, electric vehicles mostly adopt decentralized design schemes, and their cooling circulation systems are mostly designed with a single series pipeline. Specifically, such as figure 1 As shown, the cooling cycle system may include a motor controller (MCU), a drive motor, a DC converter (DC / DC), an on-board charger (OBC), a water tank, a water pump, and a cooling unit (cooling fan and low-temperature radiator), which will The above components are connected in series to form a cooling circulation system of a circulation loop. When cooling the vehicle system, the water pump starts to work, so that the coolant can flow through the motor controller, drive motor, DC converter, and on-board charger in order to cool the above components. [0003] However, wi...
