Additionally, ensuring good contact between cell components and using high-quality materials during manufacturing can help reduce resistance.
Temperature plays a substantial role in influencing internal resistance. Generally, higher temperatures lead to lower internal resistance. To enhance the performance of lithium-ion cells/batteries, various measures can be employed to reduce internal resistance. Here are some common methods: 1. Optimization of Battery Materials
High internal resistance in a pack can make it less efficient, reduce its range, and create too much heat in EVs, which can be dangerous and shorten the battery’s life. Therefore, calculating and reducing the internal resistance of battery packs is crucial in designing efficient, safe, and long-lasting battery systems.
c. Internal resistance affects the temperature characteristics of the battery. Batteries with high internal resistance generate more heat during discharge or charge, leading to an increase in battery temperature, which further affects the battery’s performance.
Internal resistance is one of the limiting factors for the output power of lithium-ion batteries. When the internal resistance of the battery is high, the current passing through the battery will result in a significant voltage drop, leading to a reduction in the battery’s output power. b. Internal resistance leads to self-discharge in batteries.
The resistance of a battery pack depends on the internal resistance of each cell and also on the configuration of the battery cells (series or parallel). The overall performance of a battery pack depends on balancing the internal resistances of all its cells.
