The test results demonstrate that high-power charging significantly impacts the durability and thermal safety of the high-capacity lithium batteries. In particular, the capacity fading rate can reach up to 30% only after 100 charge cycles depending on the battery type.
After 100 charging cycles of 1 C charge and 1 C discharge, the capacity fluctuates between 21.8 Ah and 22.3 Ah, which is acceptable. When charging at 3 C, the maximum capacity of the battery drops from 19.1 Ah to 17.4 Ah. As the cycles progressed, the maximum chargeable capacity of the battery decreases significantly.
The energy density of the currently available lithium batteries should be significantly increased to support the operation of such vehicles, and high-power charging is required to reduce the charging time.
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.
