Abstract

The embodiment of the invention discloses a thermal management pipeline of an electric vehicle power battery and a balance method of thermal management pipeline. The thermal management pipeline comprises a cooling liquid main loop and a plurality of branch pipelines (2), wherein the plurality of branch pipelines (2) are separately connected to the cooling liquid main loop (1), each branch pipeline (2) comprises a water chamber (101), the water chamber (101) is used for cooling a corresponding battery module, a first pressure meter (102) is arranged at the entrance of the water chamber (101) of each branch pipeline (2), a second pressure meter (105) is arranged at the exit of the water chamber (101) of each branch pipeline (2), a first damping valve installation position is arranged between the entrance of each branch pipeline (2) and the entrance of each branch pipeline (2), and an adjustable damping valve assembly (109) or a fixed damping valve assembly (222) based on the adjustable damping valve assembly (109) is detachably arranged at the first damping valve installation position.

Description

technical field [0001] The present invention relates to the technical field of automobiles, and more specifically, to a thermal management pipeline of a power battery of an electric vehicle, an equalization method and a calibration system thereof. Background technique [0002] Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. As a new energy vehicle with reduced oil consumption, low pollution, and low noise, electric vehicles are considered to be an important way to solve the energy crisis and environmental degradation. Hybrid vehicles take into account the advantages of pure electric vehicles and traditional internal combustion engine vehicles at the same time. On the premise of meeting the requirements of vehicle power and mileage, it eff...
