Abstract

The invention provides a lithium ion battery box for an electric automobile. The lithium ion battery box is characterized by comprising a box body, a water cooling plate, and a cover, wherein the boxbody is square and comprises a bottom plate enclosing a space for accommodating a lithium ion battery module, two long side plates and two short side plates; the water cooling plate is arranged at thebottom of the space and used for cooling the lithium ion battery module, and is provided with an inlet and an outlet; the cover is detachably mounted at the top of the box body and used for sealing the space; one short side plate is provided with a water inlet and a water outlet, which are communicated with the inlet and the outlet respectively, and are used for enabling an external cooling liquid to flow into the water cooling plate from the inlet and flow out from the outlet; a temperature sensor is arranged on the long side plate; when the temperature sensor senses that the temperature inthe space is higher than 40 DEG C, the external cooling liquid flows into the water cooling plate and flows out; the water cooling plate comprises a first pipeline and a second pipeline arranged sideby side and a plurality of side-by-side third pipelines communicated with the first pipeline and the second pipeline; the diameter of the inlet is larger than that of the outlet.

Description

technical field [0001] The invention relates to a lithium ion battery box for an electric vehicle, belonging to the field of new energy electric vehicles and power batteries. Background technique [0002] With the improvement of people's living standards, cars play an increasingly important role in people's travel. But it also brings a lot of problems, especially in energy and pollution problems. In order to solve the energy problem, various countries have introduced electric vehicles to replace traditional vehicles powered by petroleum. Compared with traditional cars, electric vehicles have the characteristics of energy saving, environmental protection, and high energy utilization rate. If electric vehicles can be vigorously promoted and used, today's increasingly prominent energy problems will be greatly alleviated. [0003] Lithium batteries have the advantages of high specific energy density, low quality, small size, long cycle life, can be repeatedly charged and disc...
