The first battery pack is configured to be connected in parallel to an alternator and a second battery pack, and has a lower capacity than the second battery pack. A negative electrode of each of the first battery cells includes a negative electrode active material. The negative electrode active material includes a carbon-based material having an interlayer spacing of a (002) plane of 0.34 nm to 0.50 nm in X-ray diffraction measurement using copper (Cu) Kα lines."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiple battery pack and operating method thereof","description":"A lithium battery system includes a first battery pack including a plurality of first battery cells connected in series.
