SPEA网络研讨会 | 电动汽车电池测试的三大挑战

新能源汽车行业蓬勃发展，驱动了锂电池市场爆发，但目前锂电池的缺陷类型复杂多样、测试成本过高、测试结果不准确等问题仍然制约着行业发展。如何解决锂电池安全问题，一直是全球自动化测试设备厂商技术研发的难点。近日，SPEA组织召开了题为“检测电池缺陷很重要：自动化测试的重要性”网络研讨会，重点分享电动汽车电池测试的三大挑战以及SPEA在电池测试领域的突破性科技成果。以下是研讨会部分内容：The rising clean energy transition has significantly increased dependence upon rechargeable batteries.
清洁能源转型的兴起大大增加了对充电电池的依赖。

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.

锂电池在当今的可充电电池行业中占据重要地位，因为它们具有高储能能力并且可以根据不同设备需求进行成型。锂电池制造正在变得具有战略意义，并且正在全球范围内兴起，主要为满足电动汽车电池的需求。拥有专业的测试设备，才能实现更快的生产周期的需求与高效的电动汽车电池测试设备相结合，进而提高产品质量。

Time, data and investment: the key factors

时间、数据和投资是关键因素

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

用户对电池质量的要求不断提升，要求厂商进行准确的电动汽车电池测试，以避免现场故障。
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.
锂电池的风险较高，是因为每辆电动汽车释放和存储的能量很高。如果在生产过程中没有准确进行电动汽车电池测试，就可能出现非常危险事故，甚至损坏品牌形象。
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，还有一个由时间、数据准确性和资源组成的巨大金钱三角，产生了电动汽车电池测试中的三大挑战：
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.
如果电池测试能力和专业知识不足，测试需要很长时间才能完成。这会延长生产周期并影响产量。
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.
电池在测试过程中，会生成大量数据，尤其是在集成不同站点的生产环境中，测量和数据可能不准确。
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.
电动汽车电池测试是应用驱动的，因为锂电池、电池芯和模块需要以电动汽车的使用方式进行测试。因此，需要重新配置电池测试设备以模拟不同的应用并符合电池产品的变化。这意味着不仅要投入大量投资在电动汽车电池测试设备上，还要大量投资在不同测试夹具，以此来支持这些变化。
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.
电动汽车电池厂商知道需要付出极大的努力才能避免该领域的故障。显然测试自动化在使电动汽车电池测试跟上生产周期时间方面发挥着关键作用。

The contribution of automatic EV battery test equipment

自动电动汽车电池测试设备的贡献

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.

市场上几乎所有的自动测试设备都解决了时间和数据准确性的挑战，但它们缺乏应对产品变化的灵活性。业内需要可适应测试要求的自动化电动汽车电池测试设备，在提高测量精度和数据管理的同时，降低电动汽车电池测试运营成本。
