6 FAQs about [Battery pack life]

How long does a battery pack last?

Battery Pack Lifespan: Due to the consistency issues of battery cells, the lifespan of the battery pack is determined by the worst-performing cell. For NMC packs, this means the cycle life is reduced by 80%, resulting in 1200–1600 cycles. For LFP packs, the reduced cycle life is approximately 3200 cycles.

How to evaluate the life of a new battery pack?

To rapidly evaluate the lifetime of newly developed battery packs, a method for estimating the future health state of the battery pack using the aging data of the battery cell's full life cycle and the early data of the battery pack is proposed. First, the battery cycle aging characteristics are analyzed from different perspectives.

How long does a battery last?

Lifespan is generally calculated based on the cell cycle lifespan and calendar lifespan: Cycle Life: The ⇲ cycle life of NMC battery cells is generally 1500–2000 cycles, while LFP battery cells typically have a much higher cycle life of approximately 4000 cycles.

How do you predict a battery pack's life cycle?
