1. Definition of lithium battery module
The battery module can be understood as the intermediate product of the battery cell and pack formed after the lithium ion battery cells are combined in series and parallel, and the single battery monitoring and management device is installed. Its structure must support, fix and protect the electric core, which can be summarized into three major items: mechanical strength, electrical performance, thermal performance and fault handling capacity. Whether the position of the battery cell can be properly fixed and protected from damaging deformation, how to meet the current carrying performance requirements, how to meet the control of the temperature of the battery cell, whether to cut off the power in case of serious abnormalities, whether to avoid the spread of thermal runaway, etc., will be the criteria for judging the quality of the battery module. The thermal management solution of battery modules with high performance requirements has turned to liquid cooling or phase change materials. As shown below:
2. Features of lithium battery module
1. The lithium battery module requires the battery to be highly consistent (capacity, internal resistance, voltage, discharge curve, life).
2. The cycle life of lithium battery module is lower than that of single battery.
3. Use under limited conditions (including charging, discharging current, charging mode, temperature, etc.).
4. The battery voltage and capacity have been greatly improved after the lithium lithium battery module is formed. It must be protected and monitored for charge equalization, temperature, voltage and overcurrent.
5. The lithium battery module must meet the voltage and capacity requirements required by the design.
