  1、Module overall design features The  battery modul e can be understood as an intermediate product between the  battery cell  and the  battery pack  formed by the combination of the  lithium-ion battery  cell in series and parallel, and the voltage and temperature monitoring and management device of the single battery. Its structure must support, fix, and protect the cell. The design requirements need to meet the requirements of mechanical strength, electrical performance, heat dissipation performance, and fault handling ability. Whether it can fully fix the cell position and protect it from deformation that damages performance. How to meet the requirements of current carrying performance. How to control the temperature of the cell. Whether to power off when encountering serious abnormalities. Whether to avoid thermal runaway propagation, etc. They will be the criteria for judging the merits of the battery module. Figure 1: Square hard shell pow...

  Solar and wind power bring renewable energy to the grid, but the imbalance between supply and demand is a major limiting factor affecting the utilization of such energy sources. Although solar power is abundant in the middle of the day, demand is not high enough at this time, so the cost of electricity for consumers remains high. Grid storage,  home storage , and  commercial and commercial energy storage systems (ESS)  can capture energy from renewable sources such as solar and wind during the day and release stored energy during periods of peak demand or when grid prices are high. By storing energy for peak use,  energy storage systems  can stabilize the grid and reduce energy costs. Design challenges associated with battery energy storage systems (BESS, which is the more common type of energy storage system) include 1. safe use; 2. Accurate monitoring of battery voltage, temperature, and current; And 3. Strong balancing ability between batteries and bet...
