Customer ServiceAn advanced Lithium Battery BMS will passively balance the voltage level of each cell within the battery at the end of the charge cycle above approximately 98% SOC. This is essential to maintaining Lithium capacity and lifetime.
Customer ServiceIn lithium batteries, maintaining balance is crucial because it allows for the most efficient use of the battery's total capacity. It also prolongs the battery's lifespan by preventing overcharging or over-discharging of individual cells.
Balancing lithium batteries in parallel involves measuring each battery's voltage before connection, ensuring they're within an acceptable range of each other, and then connecting all positive and negative terminals together. What Does It Mean For Lithium Batteries To Be Balanced?
With the advancement of EV technologies, lithium-ion (Li-ion) battery technology has emerged as the most prominent electro-chemical battery in terms of high specific energy and specific power. The Li-ion battery pack is made up of cells that are connected in series and parallel to meet the voltage and power requirements of the EV system.
Contributed Commentary by Anton Beck, Battery Product Manager, Epec When a lithium battery pack is designed using multiple cells in series, it is very important to design the electronic features to continually balance the cell voltages. This is not only for the performance of the battery pack, but also for optimal life cycles.
When individual lithium cells, each with slight manufacturing differences and unique characteristics, are linked together in series to achieve the desired output voltage for a system, imbalances in charge levels can occur during the battery's charge and discharge cycles.
Balancing lithium battery packs, like individual cells, involves ensuring that all batteries within a system maintain the same state of charge. This process is essential when multiple battery packs are used together in series or parallel configurations.
