Data-driven model improves accuracy in predicting EV battery degradation

Rising carbon emissions have significantly challenged sustainable development in recent years, prompting global efforts to implement carbon reduction policies and achieve long-term carbon neutrality. A crucial step in this transition involves the recycling and reuse of power batteries, which are assessed for their state-of-health (SoH) and then repaired or restructured for reuse in smaller-sized electric vehicles (EVs), energy storage systems, and smart streetlights. This process not only extends battery life but also maximizes their residual value. However, accurately assessing this […]

Detailed Guide to LangChain Text Splitters with Examples

What are LangChain Text Splitters In recent times LangChain has evolved into a go-to framework for creating complex pipelines for working with LLMs. One of its important utility is the langchain_text_splitters package which contains various modules to split large textual data into more manageable chunks. Usually, LangChain Text Splitters are used in RAG architecture to chunk a large document and convert these chunks into embeddings to be stored in Vector DB. For LLMs with limited context-size windows, it is quite […]
