Further, the migration characteristics of the temperature threshold of battery thermal runaway are investigated using the proposed procedure. The test results demonstrate that high-power charging significantly impacts the durability and thermal safety of the high-capacity lithium batteries.
Based on the performance of the tested samples, charging rates of more than 3 C can considerably impact the durability and safety performance of batteries. Even though the severity level of this impact varies across the tested batteries, all the levels are observed to be unacceptable.
The internal resistance of the battery has a greater influence on high power charges due to the fact that the heat generated per unit of time equals the power lost through the resistance. Therefore, charging at a faster rate will result in greater energy consumption , .
Preventing thermal runaway and fire dangers while preserving performance is critical for consumer trust and regulatory compliance. − A battery’s capacity, performance, and safety are all affected by the charging and discharging techniques. As a result, charging and discharging pose a significant challenge.
During the charging process, some energy is lost as heat. In technical terms, this is referred to as thermal loss. The internal resistance of the battery has a greater influence on high power charges due to the fact that the heat generated per unit of time equals the power lost through the resistance.
