Abstract

The invention discloses a battery integral temperature regulating system of a new energy automobile. The battery integral temperature regulating system of the new energy automobile comprises a battery box body, wherein a battery pack formed by a plurality of single batteries through distribution in rows is arranged in the battery box body; a PTC (positive temperature coefficient) heating sheet is arranged between every two adjacent single batteries; a snake-shaped circulation cooling pipeline is arranged at two sides of the battery pack; an inlet and an outlet of the circulation cooling pipeline are introduced out of the battery box body, and are connected to a cooling water supply system; a first exhaust opening is formed in one side of the battery box body; a first opening degree valve and a first exhaust fan are arranged at the first exhaust opening; the other side of the battery box body is provided with a second exhaust opening; a second opening degree valve and a second exhaust fan are arranged at the second exhaust opening; a temperature sensor is arranged in the battery box body; the temperature sensor, the first opening degree valve, the first exhaust fan, the second opening degree valve, the second exhaust fan, the cooling water supply system and a PTC heating sheet main power supply circuit are connected with a controller.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a battery comprehensive temperature adjustment system for new energy vehicles. Background technique [0002] At present, due to the energy crisis and the problems caused by air pollution, people are eager to develop new energy that can fully replace traditional petroleum energy. In this context, the power battery should be born. The use of power batteries in automobiles to replace conventional oil and other energy sources can not only alleviate the energy crisis, but also reduce environmental pollution because the power batteries themselves are non-polluting. [0003] With the rapid development of electric vehicles, the performance of power batteries has become the key to the popularization of electric vehicles. However, the power battery is more sensitive to the ambient temperature, which limits its own development and popularization. Take the lithium-...
