电池化成
旨在提高电池化成设备的精度和效率的解决方案
随着使用电池作为电源的设备与日俱增,特别是电动汽车(EV)快速发展,全球电池需求日益增长。但是,电池必须先进行化成和测试,然后才能安装到系统中。电池化成过程采用专门的电池化成设备对电池进行充电和放电,需要高精度电压和电流,以确保电池实现规定的使用寿命。只有在顺利通过测试之后,电池才能被视为可以进入市场。
耗费时间的化成过程
目前,电池化成是电池生产过程中的主要瓶颈。为了激活刚刚装配好的电池单元或电池组中的材料,需要花费长达20小时的时间进行充电放电循环。但这个过程必不可缺,因为它极大地影响着电池的使用寿命、质量和成本。几乎每一个新生产的电池都必须在经过化成和测试过程之后,才能安装到系统中。执行这些关键工序的电池化成设备必须配备适当的电源系统,通常是AC-DC或DC-DC级。

生产过程要求高精度和可靠性
大多数电池设备制造商都希望供应商提供适用的电池化成电源系统解决方案。理想情况下,它可:
- 实现高达0.01%的电压和电流精度。
- 进行MOSFET散热管理,以满足更高额定电流要求。
- 通过提高额定电流值来提高总功率密度。
- 提升全天候运行的系统解决方案的可靠性。
一般而言,制造商寻求的是未经过度设计的优质系统解决方案。这样的解决方案应当拥有颇具吸引力的性价比,同时具备杰出的可靠性和稳定性,能够在特定条件下实现连续运行。考虑到空间宝贵,高功率密度是缩小解决方案尺寸的绝佳途径,同时也是常用的首选方法。选择能够灵活扩展,以满足各种要求的标准平台,可以让制造商快速将产品推向市场。

Getting the most out of batteries. By the end of this decade, the majority of new cars sold around the world is expected to have a partially or fully electric drivetrain. Battery management systems have a great impact on the range, cost and service life of electric vehicles, which makes them a key success factor for this mobility revolution. Furthermore, they play an essential role when it comes to second-life concepts that allow former EV batteries to be used as flexible storage for renewable energy, for example. Dr. Clemens Mueller exclusively explains in-depth market trends and challenges, provides details on Infineon products and solutions, and introduces the new BMS-IC TLE9012AQU.
