6 FAQs about [Factors affecting the internal resistance of the battery pack]

Why is internal resistance important in a battery pack?

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.

Why is internal resistance a limiting factor in lithium ion batteries?

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.

What is internal resistance in a battery?

Internal resistance is a natural property of the battery cell that slows down the flow of electric current. It’s made up of the resistance found in the electrolyte, electrodes, and connections inside the cell. In single battery cells, this resistance decides how much energy is lost as heat when the battery charges and discharges.

What factors affect the internal resistance of a battery?

The contact resistance between the battery’s electrodes and the electrolyte is another significant factor affecting internal resistance. Lower contact resistance results in lower internal resistance. 4. Battery Structural Design The design of the battery’s structure can also have a significant impact on internal resistance.

Does battery discharge rate affect internal resistance?

For a variety of BTM technologies, the battery’s internal resistance always plays a critical role in the heat generation rate of the battery. Many factors (temperature, SOC and discharge rate) impact on the internal resistance, however, scant research has explored the effect of battery discharge rate on the internal resistance.

Does temperature affect battery internal resistance?

The deviation between the two measured values is around 70 m Ω, the lower the battery ambient temperature, the greater the internal resistance value. This finding is consistent with Yang’s study (Lai et al., 2019). Therefore, the temperature is one of the crucial factors which can influence the battery internal resistance. Fig. 5.
