新能源汽車行業(yè)蓬勃發(fā)展，驅(qū)動了鋰電池市場爆發(fā)，但目前鋰電池的缺陷類型復雜多樣、測試成本過高、測試結(jié)果不準確等問題仍然制約著行業(yè)發(fā)展。如何解決鋰電池安全問題，一直是全球自動化測試設備廠商技術(shù)研發(fā)的難點。近日，SPEA組織召開了題為“檢測電池缺陷很重要：自動化測試的重要性”網(wǎng)絡研討會，重點分享電動汽車電池測試的三大挑戰(zhàn)以及SPEA在電池測試領域的突破性科技成果。以下是研討會部分內(nèi)容：The rising clean energy transition has significantly increased dependence upon rechargeable batteries.
清潔能源轉(zhuǎn)型的興起大大增加了對充電電池的依賴。

Lithium-ion batteries dominate today’s rechargeable battery industry as they have high energy storage capacities and can be shaped according to any device. Lithium-ion batteries manufacturing is becoming strategic and it is ramping up around the world to primarily match electrical vehicle battery demand. With it, the demand for faster production cycles combined with efficient EV battery testing equipment for higher product quality.

鋰電池在當今的可充電電池行業(yè)中占據(jù)重要地位，因為它們具有高儲能能力并且可以根據(jù)不同設備需求進行成型。鋰電池制造正在變得具有戰(zhàn)略意義，并且正在全球范圍內(nèi)興起，主要為滿足電動汽車電池的需求。擁有專業(yè)的測試設備，才能實現(xiàn)更快的生產(chǎn)周期的需求與高效的電動汽車電池測試設備相結(jié)合，進而提高產(chǎn)品質(zhì)量。

Time, data and investment: the key factors

時間、數(shù)據(jù)和投資是關鍵因素

The steadily growing quality requirements mandate accurate electric vehicle battery testing to avoid failures in the field.

用戶對電池質(zhì)量的要求不斷提升，要求廠商進行準確的電動汽車電池測試，以避免現(xiàn)場故障。
Because lithium-ion batteries are very hazardous, due to the high energy released and stored in one single electrical vehicle, the potential for very dangerous situations and loss of brand image is considerably high if EV battery testing doesn’t accurately occur during the production cycles.
鋰電池的風險較高，是因為每輛電動汽車釋放和存儲的能量很高。如果在生產(chǎn)過程中沒有準確進行電動汽車電池測試，就可能出現(xiàn)非常危險事故，甚至損壞品牌形象。
Beyond safety, there is a very large money triangle, made of time, data accuracy, and resources, that generates the top 3 challenges in electric vehicle battery testing:
除了安全之外，還有一個由時間、數(shù)據(jù)準確性和資源組成的巨大金錢三角，產(chǎn)生了電動汽車電池測試中的三大挑戰(zhàn)：
1、Testing takes a long time to be completed if there is insufficient battery testing capacity and expertise. This extends the production cycle time and penalizes volumes.
如果電池測試能力和專業(yè)知識不足，測試需要很長時間才能完成。這會延長生產(chǎn)周期并影響產(chǎn)量。
2、 During testing, a large amount of data is generated and, especially in production environments that integrate different stations, measurements and data can be inaccurate.
電池在測試過程中，會生成大量數(shù)據(jù)，尤其是在集成不同站點的生產(chǎn)環(huán)境中，測量和數(shù)據(jù)可能不準確。
3、Electric vehicle battery testing is application-driven as lithium-ion batteries, cells, and modules need to be tested in the way that the electrical vehicle would be used. Battery testing equipment reconfigurations are therefore required to mimic different applications and comply with battery product changes. This implies a significant capital investment not only in the EV battery testing equipment that’s being used but also in the integration of the different testing fixtures to support the changes.
電動汽車電池測試是應用驅(qū)動的，因為鋰電池、電池芯和模塊需要以電動汽車的使用方式進行測試。因此，需要重新配置電池測試設備以模擬不同的應用并符合電池產(chǎn)品的變化。這意味著不僅要投入大量投資在電動汽車電池測試設備上，還要大量投資在不同測試夾具，以此來支持這些變化。
Companies manufacturing electric vehicle batteries understand how much effort is required to avoid failures in the field. It is evident that test automation plays a critical role in enabling electrical vehicle battery testing to keep pace with production cycle time.
電動汽車電池廠商知道需要付出極大的努力才能避免該領域的故障。顯然測試自動化在使電動汽車電池測試跟上生產(chǎn)周期時間方面發(fā)揮著關鍵作用。

The contribution of automatic EV battery test equipment

自動電動汽車電池測試設備的貢獻

Nearly every automatic testing equipment on the market solves time and data accuracy challenges but they lack the flexibility to product changes. Having automatic EV battery testing equipment that adapts as the testing requirements evolve, while improving measurement accuracy and data management, reduces EV battery testing operating costs.

市場上幾乎所有的自動測試設備都解決了時間和數(shù)據(jù)準確性的挑戰(zhàn)，但它們?nèi)狈獙Ξa(chǎn)品變化的靈活性。業(yè)內(nèi)需要可適應測試要求的自動化電動汽車電池測試設備，在提高測量精度和數(shù)據(jù)管理的同時，降低電動汽車電池測試運營成本。
