Ampace x TDK at Japan’s International Smart Energy Week: Pioneering a New Era of Safe Energy with Full-Stack Energy Storage Solutions.

2025-06-03 | Calvin

From February 19 to 21, 2025, the International Smart Energy Week in Japan, one of the global energy industry's most anticipated events, took place in Tokyo. As a leading global provider of lithium battery solutions, Ampace joined forces with TDK to showcase a combination of "full-scenario energy storage product matrix + full-lifecycle service support."

Addressing Japan's Market Pain Points: Safety, Reliability, and Full Lifecycle Economy as Core Demands

Japan is accelerating the application of renewable energy and energy storage technologies. However, its complex geography and stringent disaster prevention standards present dual challenges for energy storage systems: on the one hand, natural disasters like earthquakes and typhoons demand products with exceptional seismic resistance and thermal runaway protection; on the other hand, industrial and commercial users are highly sensitive to the full lifecycle costs of energy storage systems.

With the collaboration with TDK, Ampace has launched region-specific solutions:

• Extreme Safety Design: Featuring Ampace's self-developed Kunlun 2.0 GT40 cells, utilizing a high-stability lithium iron phosphate system and ceramic-coated separator technology, ensuring that the risk of thermal runaway is minimized to near zero. The system-level protection has passed multiple international certifications, including IEC62619, UL 9540A, and complies with Japan's JET fire resistance standards.
• Seismic Reliability: The UniC DG500 industrial and commercial energy storage cabinet adopts a modular pressure design and cabinet buffer structure, capable of withstanding continuous aftershock impacts. It has been successfully applied in an industrial project in Kagoshima, Japan, with an optimized installation layout that fully meets fire department requirements.
• Long Lifespan: Kunlun cells have a cycle life exceeding 15,000 cycles, with a capacity retention rate (SOH) of up to 80%, offering a service life of over 20 years, significantly reducing replacement frequency and maintenance costs.
• Wide Temperature Range: Kunlun cells support stable charging and discharging in extreme climates, ranging from -20°C to 60°C, perfectly adapting to environments from high temperatures to extreme cold, ensuring uninterrupted operation year-round.

Product Matrix in Action: Full-Spectrum Coverage, Technological Advantages Leading the Industry

Ampace's four major product lines, showcased at this event, are all centered on "high energy density, long lifespan, and low maintenance" as their core competitive advantages:

• Home Energy Storage RESS PR-S1: Modular stacked design supports flexible capacity expansion from 3.3kWh to 23.3kWh. The IP55 protection level suits Japan's rainy climate, while the -20°C low-temperature discharge capability ensures emergency power for homes in cold areas like Hokkaido.
• Industrial and Commercial Energy Storage Flagship UniC DG500: With a single cabinet capacity of 532.48kWh, it supports expansion to 4.2MWh by paralleling 8 cabinets. Equipped with Kunlun 2.0 GT40 cells, its service life can reach 20 years.
• High-Power UPS PU100: A 6C discharge rate provides 10-15 minutes of rapid backup power. Compared to traditional lead-acid batteries, it saves 70% of space. It is also certified with global safety standards such as UL9540A, meeting the continuous operational requirements of data centers.
• Portable Power Supply Andes Series: Available in 266Wh, 584Wh, and 1462Wh models, with Andes 1500 featuring a 1462Wh capacity and 3600W peak power, supporting emergency power supply after disasters, making it a new favorite for emergency power storage in Japanese homes.

TDK Local Empowerment: Full Lifecycle Service from R&D to Decommissioning

The deep collaboration between Ampace and TDK provides "technology + service" dual protection for Japanese customers:

• Certification and Testing Support: TDK provides testing, multi-functional combustion testing labs, and other facilities to ensure certification by JET (Japan Electric Safety & Environmental Technology Laboratory).
• Rapid Response System: Offering technical support for general warehouse storage, with a professional technical team providing full lifecycle services from design and installation to end-of-life (EOL).

President of Ampace's Energy Storage Division, Zhu Yansong, said: "The Japanese market is a key part of our global strategy. We not only provide products but are committed to working with TDK to build a 'zero-distance' service ecosystem, accelerating Japan's carbon-neutral process with safe and reliable energy storage solutions."

Amidst the global energy transition wave, Ampace is driving both technological innovation and localized services to redefine energy storage value, injecting dynamic power into humanity's green future.
