Customer ServiceThe 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.
However, charging beyond 1C, like at 2C or higher, can significantly reduce the battery’s lifespan. Rapid discharge can indeed be harmful if it leads to excessive heat buildup. However, lithium-ion batteries are designed to handle certain levels of immediate dismissal without damage.
However, this is only partially true. The lithium-ion battery’s voltage increases as it charges, but the relationship is not linear. It can vary based on several factors, including the battery’s age and temperature. For instance, a typical lithium-ion cell might show a voltage of 3.7V at 50% charge.
Research indicates that storing a battery at a 40% charge reduces the loss of capacity and the rate of aging. For instance, a study found that lithium-ion batteries stored at 40% charge retained approximately 97% of their power after one year, compared to around 94% when stored at 100%. Temperature extremes can indeed affect lithium-ion batteries.
