Recent data shows that electric vehicle (EV) batteries last longer than experts previously predicted, although many consumers are still worried about the cost of replacing them.

最新數據顯示，電動車 (EV) 電池的壽命比專家先前預測的更長，儘管許多消費者仍擔心更換電池的成本。

There is a clear difference between how batteries actually perform and how consumers perceive them. For example, early EVs made between 2011 and 2016 had a battery replacement rate of about 8.3%, whereas vehicles made from 2022 onwards have a rate of only 0.3%. This improvement is due to better chemical materials and improved cooling systems. Consequently, most EVs keep 95% of their original range after five years. Furthermore, research from Stanford University suggests that normal daily driving may actually extend battery life by up to 38% compared to strict laboratory tests.

電池的實際表現與消費者的認知之間存在明顯差異。例如，2011年至2016年間製造的早期電動車，電池更換率約為8.3%，而2022年以後製造的車輛更換率僅為0.3%。此項進步歸功於更好的化學材料與改良的冷卻系統。因此，大多數電動車在五年後仍能維持95%的原始續航力。此外，史丹佛大學的研究顯示，與嚴格的實驗室測試相比，正常的日常駕駛實際上可將電池壽命延長至38%。

Despite these technical improvements, market growth is inconsistent. In the United States, EV sales dropped by 25% in 2026 because the government stopped providing subsidies. In contrast, Australia saw an increase in deliveries in June, although this was mainly caused by unstable fuel prices rather than a change in consumer confidence. The main problem remains the high cost of replacing batteries outside of warranty, which can cost between $5,000 and $16,000. However, new modular designs now allow drivers to replace individual cells instead of the entire battery pack.

儘管有這些技術改良，市場增長仍不一致。在美國，由於政府停止提供補貼，2026年電動車銷售額下降了25%。相比之下，澳洲6月份的交付量有所增加，但這主要是由不穩定的油價所致，而非消費者信心的改變。主要問題仍在於保固期外更換電池的高昂成本，費用可能在5,000至16,000美元之間。然而，新的模組化設計現在允許駕駛者更換個別電芯，而無需更換整個電池組。

Finally, how a driver uses the car affects the battery's lifespan. Data from Geotab indicates that using high-power fast-charging frequently causes the range to drop twice as fast as low-power charging. Additionally, extreme temperatures and keeping the battery at 0% or 100% can damage long-term capacity. While the actual driving range is often 5% to 16% lower than what manufacturers claim, this is usually caused by the environment and driver behavior rather than a failure of the battery itself.

最後，駕駛者的使用習慣會影響電池壽命。Geotab 的數據指出，頻繁使用高功率快充會導致續航力下降速度比低功率充電快兩倍。此外，極端溫度以及將電池維持在0%或100%可能會損害長期容量。雖然實際行駛里程通常比製造商宣稱的低5%至16%，但這通常是由環境和駕駛行為引起的，而非電池本身失效。

EV batteries are now proving to be as durable as traditional petrol engines. Although market growth varies by region, experts predict that EVs will hold nearly 25% of the global market by 2030.

電動車電池現在證明與傳統汽油引擎一樣耐用。雖然市場增長因地區而異，但專家預測到2030年，電動車將佔全球市場近25%。
