FAQS 4
Why do lithium-ion batteries deteriorate faster during fast charging?
During fast charging of lithium-ion batteries (LIBs), cell overheating and overvoltage increase safety risks and lead to faster battery deterioration. Moreover, in conventional battery management systems (BMSs), the cell balancing, charging strategy, and thermal regulation are treated separately at the expense of faster cell deterioration.
How do you stop a lithium ion battery from being uneven?
Charge batteries the right way to stop uneven cells. Use chargers with BMS and follow charging rules to make batteries work better. Manufacturing inconsistencies are one of the primary causes of cell imbalance in lithium-ion battery packs.
What is lithium battery imbalancing?
Lithium battery cells imbalancing occurs when individual cells in a battery pack exhibit varying states of charge, capacity, or voltage. This discrepancy can compromise the battery’s overall performance and safety. For instance: Variations in capacity and impedance create uneven cell currents, generating heat and temperature gradients.
Can lithium batteries be connected in series?
Connecting lithium batteries in series to form a battery pack can achieve the required capacity and voltage. However, as the batteries are used for extended periods, some individual cells in the battery pack may experience abnormal failures, affecting the performance and safety of the battery pack.
