Demand for secondhand electric vehicle (EV) batteries has risen sharply in Australia, transforming the landscape of salvage auctions. Once largely ignored, written‑off EVs now attract buyers primarily interested in their powerful lithium batteries. These batteries can be repurposed for solar storage, off‑grid power systems, or temporary energy use at events like music festivals.

The auction house Pickles reports selling about 100 salvaged EVs monthly, with sales up 200% year on year. Specialists note that even batteries reduced to 70% capacity remain useful, offering quieter and cleaner alternatives to diesel generators.

Repurposed units are also seen as an important part of Australia’s renewable energy transition. Experts believe these “second‑life” batteries could continue operating for up to 20 years and help meet the country’s growing need for short‑term energy storage.

報廢電池再生：澳洲能源新商機

澳洲對二手電動車（EV）電池的需求大幅攀升，徹底改變了報廢車拍賣市場的樣貌。過去多半乏人問津的報廢電動車，如今吸引了主要看重其高效能鋰電池的買家。這些電池可被再利用於太陽能儲能、離網電力系統，或音樂祭等活動中的臨時用電。

拍賣行 Pickles 表示，每月約售出一百輛報廢電動車，銷量年增率高達 200%。專家指出，即使是容量降至 70% 的電池仍具備實用價值，可作為比柴油發電機更安靜且更潔淨的替代方案。

再利用的電池也被視為澳洲邁向再生能源轉型的重要一環。專家認為，這些「第二生命」電池可持續運作長達二十年，並有助於滿足該國對短期能源儲存日益成長的需求。
