The application characteristics of batteries primarily include temperature, charging time, charging capacity, energy consumption, and efficiency. The MSCC charging strategy effectively prevents overheating of the battery during the charging process by controlling the charging current.
By adopting this charging method, it is possible to minimize detrimental morphological changes in the anode material, reduce the rate of side reactions, and ultimately contribute to enhancing the overall performance and longevity of the battery.
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.
It significantly improves the charging speed and enhances the comfort and convenience of residents' travel, reducing the waiting time for charging. By implementing centralized battery charging scheduling, it reduces the impact of charging on the power grid and improves the scientific planning of the grid's distribution.
Since the charging method can impact the performance and cycle life of lithium-ion batteries, the development of high-quality charging strategies is essential. Efficient charging strategies need to possess advantages such as high charging efficiency, low battery temperature rise, short charging times, and an extended battery lifespan.
When establishing design standards based on charging time, it is crucial to consider the safety and reliability of batteries. Insufficient charging time can result in incomplete charging or battery damage due to excessive charging current, leading to a chemical imbalance within the battery.
