新能源汽車行業(yè)蓬勃發(fā)展，驅(qū)動(dòng)了鋰電池市場(chǎng)爆發(fā)，但目前鋰電池的缺陷類型復(fù)雜多樣、測(cè)試成本過(guò)高、測(cè)試結(jié)果不準(zhǔn)確等問(wèn)題仍然制約著行業(yè)發(fā)展。如何解決鋰電池安全問(wèn)題，一直是全球自動(dòng)化測(cè)試設(shè)備廠商技術(shù)研發(fā)的難點(diǎn)。近日，SPEA組織召開(kāi)了題為“檢測(cè)電池缺陷很重要：自動(dòng)化測(cè)試的重要性”網(wǎng)絡(luò)研討會(huì)，重點(diǎn)分享電動(dòng)汽車電池測(cè)試的三大挑戰(zhàn)以及SPEA在電池測(cè)試領(lǐng)域的突破性科技成果。以下是研討會(huì)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(duì)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(dāng)今的可充電電池行業(yè)中占據(jù)重要地位，因?yàn)樗鼈兙哂懈邇?chǔ)能能力并且可以根據(jù)不同設(shè)備需求進(jìn)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(dòng)汽車電池的需求。擁有專業(yè)的測(cè)試設(shè)備，才能實(shí)現(xiàn)更快的生產(chǎn)周期的需求與高效的電動(dòng)汽車電池測(cè)試設(shè)備相結(jié)合，進(jìn)而提高產(chǎn)品質(zhì)量。

Time, data and investment: the key factors

時(shí)間、數(shù)據(jù)和投資是關(guān)鍵因素

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

用戶對(duì)電池質(zhì)量的要求不斷提升，要求廠商進(jìn)行準(zhǔn)確的電動(dòng)汽車電池測(cè)試，以避免現(xiàn)場(chǎng)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(fēng)險(xiǎn)較高，是因?yàn)槊枯v電動(dòng)汽車釋放和存儲(chǔ)的能量很高。如果在生產(chǎn)過(guò)程中沒(méi)有準(zhǔn)確進(jìn)行電動(dòng)汽車電池測(cè)試，就可能出現(xiàn)非常危險(xiǎn)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(gè)由時(shí)間、數(shù)據(jù)準(zhǔn)確性和資源組成的巨大金錢三角，產(chǎn)生了電動(dòng)汽車電池測(cè)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(cè)試能力和專業(yè)知識(shí)不足，測(cè)試需要很長(zhǎng)時(shí)間才能完成。這會(huì)延長(zhǎng)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(cè)試過(guò)程中，會(huì)生成大量數(shù)據(jù)，尤其是在集成不同站點(diǎn)的生產(chǎn)環(huán)境中，測(cè)量和數(shù)據(jù)可能不準(zhǔn)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(dòng)汽車電池測(cè)試是應(yīng)用驅(qū)動(dòng)的，因?yàn)殇囯姵亍㈦姵匦竞湍K需要以電動(dòng)汽車的使用方式進(jìn)行測(cè)試。因此，需要重新配置電池測(cè)試設(shè)備以模擬不同的應(yīng)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(dòng)汽車電池測(cè)試設(shè)備上，還要大量投資在不同測(cè)試夾具，以此來(lái)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(dòng)汽車電池廠商知道需要付出極大的努力才能避免該領(lǐng)域的故障。顯然測(cè)試自動(dòng)化在使電動(dòng)汽車電池測(cè)試跟上生產(chǎn)周期時(shí)間方面發(fā)揮著關(guān)鍵作用。

The contribution of automatic EV battery test equipment

自動(dòng)電動(dòng)汽車電池測(cè)試設(shè)備的貢獻(xiàn)

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(chǎng)上幾乎所有的自動(dòng)測(cè)試設(shè)備都解決了時(shí)間和數(shù)據(jù)準(zhǔn)確性的挑戰(zhàn)，但它們?nèi)狈?yīng)對(duì)產(chǎn)品變化的靈活性。業(yè)內(nèi)需要可適應(yīng)測(cè)試要求的自動(dòng)化電動(dòng)汽車電池測(cè)試設(shè)備，在提高測(cè)量精度和數(shù)據(jù)管理的同時(shí)，降低電動(dòng)汽車電池測(cè)試運(yùn)營(yíng)成本。

SPEA has addressed the top 3 challenges in electrical vehicle battery testing by designing an innovative automatic EV battery test equipment that meets throughput, accuracy and flexibility requirements.
