Safe and reliable new energy automobile battery system

Abstract

The invention discloses a safe and reliable new energy automobile battery system. Battery boxes are clamped in a chassis, and the bottoms of the battery boxes are sealed by two bottom plates; batteries are arranged on the two bottom plates, and a locking mechanism is arranged between the two bottom plates; the chassis is connected with a refrigerant heat dissipation mechanism; the battery box is connected with an air cooling heat dissipation mechanism; the refrigerant heat dissipation mechanism and the air cooling heat dissipation mechanism dissipate the heat of the battery boxes at the same time; all the battery boxes are also connected with a negative pressure pumping mechanism, and the negative pressure pumping mechanism pumps the negative pressure for the battery boxes; when the temperature in the battery boxes is greater than T1, the locking mechanism is unlocked, the two bottom plates are opened, and the batteries are separated from the corresponding battery boxes. The double heat dissipation is carried out on the battery boxes at the same time through the refrigerant heat dissipation mechanism and the air cooling heat dissipation mechanism, so the heat dissipation effect isgood. When one battery abnormally releases flammable and combustible gas, the negative pressure pumping mechanism can timely discharge the flammable and combustible gas released by the battery; when the temperature of the battery continuously rises to be possibly spontaneously combusted, the battery can be separated from the automobile through unlocking of the locking mechanism.

Description

technical field [0001] The invention relates to the technical field of electric vehicle batteries, in particular to a safe and reliable new energy vehicle battery system. Background technique [0002] In recent years, with the transformation of automobile technology and in response to the country's call for energy conservation and environmental protection, new energy vehicles have emerged as the times require, which has promoted the rapid development of new energy vehicle technology. Among them, electric vehicles are powered by on-board power supplies. Compared with gasoline vehicles, they have less impact on the environment and can replace non-renewable gasoline resources. Their development prospects are widely optimistic. [0003] But at present, many technologies of electric vehicles are still immature, especially batteries, because batteries have certain requirements on temperature when they are working. Serious potential safety hazards. In recent years, there have been...

Problems solved by technology

[0003] But at present, many technologies of electric vehicles are still immature, especially batteries, because batteries have certain requirements on temperature when they are working. Serious potential safety hazards. In recent years, there have been too many car safety accidents caused by battery spontaneous combustion, which has seriously affected people's recognition of electric vehicles.
