How does the internal resistance of a battery affect the charging process?

The internal resistance of the direct current (DC) battery plays a crucial role in the charging process by causing voltage drops, power losses, and affecting the charging speed and efficiency. As shown in Fig. 6 (d), the internal resistance of a battery varies constantly during the charging process.

What is the internal resistance of a battery?

The internal resistance of a battery reflects the energy losses during charge processes, as well as the battery's internal health. The internal resistance sensor is utilized in the MSCC charging strategy to continuously monitor the battery's internal resistance.

How much stress does a steel sheet pile have?

On the foundation pit side, the vertical stress of the steel sheet pile showed compressive stress, which first increased with depth, increased to the maximum value (1.28 MPa) at 12.54 m, and then gradually decreased from 12.54 m to 13.00 m (at the bottom of the steel sheet pile).

Why is external stack pressure important for lithium-based rechargeable batteries?

On the other hand, the external stack pressure is also inevitable for lithium-based rechargeable batteries, extensively occurring during manufacturing and time of operation and can be either beneficial or detrimental to the battery performance.

What happens when the internal resistance reaches a predetermined threshold?

When the internal resistance reaches the predetermined threshold, the system will automatically adjust the charging current or implement other measures to optimize the charging process. This adjustment aims to enhance charging efficiency and prolong battery lifespan.

Does CC-CV charging increase battery life?

While CC-CV charging is a common method with relatively high charging efficiency, it may pose the risk of overcharging for smaller capacity batteries, requiring strict control over the values of CC and CV. The MSCC charging strategy can effectively extend battery life, and reduce the risks of overcharging and overdischarging.
