Introduction

In energy storage systems, for inverters, converters (PCS), and battery management systems (BMS) to meet requirements such as a lifespan of over ten years, low loss, high stability, and resistance to harsh environments, the real challenge often lies not in topological innovation, but in the long-term stability of capacitors in the end-user equipment under complex stresses such as high temperature, high pressure, strong ripple, and wide temperature range.

Internal temperature rise caused by ripple current, efficiency degradation caused by ESR growth, early failure under overvoltage shocks… these “invisible stresses” are among the main causes of field failures in energy storage equipment.

YMIN: More Than Just Capacitors, Providing “Energy Storage-Specific Selection Logic”

For a long time, Yongming has continuously focused on the capacitor application needs of core units such as energy storage converters and BMS. We recognize the significant differences between energy storage and industrial power supply conditions—high-frequency charging and discharging, wide temperature range, long lifespan, and low ESR requirements are all indispensable.

Therefore, YMIN doesn't simply list product parameters for energy storage scenarios; instead, it provides you with multi-type capacitor selection strategies and solutions tailored to actual operating conditions.

We cordially invite you to attend our conference.

"Intelligent manufacturing" is not just a slogan, but the repeatability of every single capacitor. Yongming will guide you to witness firsthand how "automation, digitalization, and intelligence" translate into consistent capacitor quality. We sincerely invite you to join us on-site to focus on the real-world operating conditions of energy storage capacitors and discuss how to improve system lifespan through selection and manufacturing processes.

April 24th, Shanghai Yongming Intelligent Manufacturing Industrial Park. We look forward to discussing these topics with you.
