How to read the current of liquid-cooled lithium battery

In the design of a project, the first step must be to clarify the customer's needs. In addition to general needs, you should also put yourself in the shoes of the surrounding needs. Even if the customer does not mention it, we'd better consider it privately in advance. For liquid cooling systems, the basic requirements. . The overall design, according to the input requirements, generally considers the frame of the cooling system. According to the system heating power density and sealing, allowable temperature range, cost requirements, etc., select. [pdf]
