Lithium Grid News: The current liquid cooling solution for power battery systems is developing in a somewhat similar direction. As shown in the figure below:

A) The uniformity of the solution in a large area is relatively poor, making it difficult to control the temperature difference when the slab is laid;

B) These are our main two Variant, the difference between the horizontal and vertical layout is mainly reflected in the matching of the module layout and the flow channel;

C) PHEV still retains this;

D) In u200bu200bNorth America, the battery core edges (soft-pack batteries/cylindrical batteries) are directly running along the cooling direction, succumbing to the cost of the cooling plate, and balancing design choices on the fast charging capacity.

Although the cooling system of Daimler’s EQC that I saw before, although hideous, the evolution of the main body is still following the way of the previous Smart EV module.

Here is to review this piece, this system is directly from the Pack into the module, the main components are basically the cooling plate, the cooling pipe Assembly composition.

Summary: The general direction of each company is still based on its continuous data accumulation, and then based on the previous data. Slowly adjust according to changes in demand, there is some path dependence.
