From February 19 to 21, 2025, the World Smart Energy Week Japan—a globally renowned event in the energy industry—will be held in Tokyo. As a leading lithium battery solutions provider, Ampace is joining forces with TDK to showcase a comprehensive portfolio of energy storage solutions, combining an extensive product matrix across all application scenarios with full lifecycle service support. The exhibition will feature innovative products across four key segments: residential energy storage (RESS), commercial & industrial (C&I) storage, uninterruptible power supply (UPS), and portable power stations. In addition, Ampace will introduce cutting-edge safety technologies and a localized service system tailored for the Japanese market, drawing significant attention from the global energy sector.

Addressing Japan’s Market Challenges: Safety, Reliability & Lifecycle Economics

As a country prone to earthquakes and heavily reliant on energy imports, Japan is accelerating the adoption of renewable energy and energy storage technologies, aiming to achieve 36%-38% renewable energy generation by 2030. However, the country’s complex geographic conditions and stringent disaster prevention standards pose dual challenges for energy storage systems:

 • Extreme natural disasters such as earthquakes and typhoons demand exceptional seismic resistance and advanced thermal runaway protection.

 • Commercial and industrial users are highly sensitive to lifecycle costs, including ease of maintenance and energy efficiency.

Leveraging its strategic collaboration with TDK, Ampace has developed tailored solutions under the philosophy of “Safety at the Core, Reliability as the Foundation, and Service as the Key”:

Unparalleled Safety Design: Multi-Layered Protection from Cell to System

 • Cell-Level Safety: The proprietary Kunlun 2.0 GT40 cell utilizes an ultra-stable LFP (Lithium Iron Phosphate) chemistry with ceramic-coated separator technology, significantly reducing the risk of thermal runaway to nearly zero.

 • System-Level Protection: The UniC DG500 C&I energy storage cabinet features an innovative thermal insulation design, along with triple safety detection (smoke, temperature, and CO gas sensors) and an aerosol-based fire suppression system. It has obtained IEC 62619, UL 9540A certifications and ‘certified by Japan-specific JET propagation test.

Seismic Reliability: Engineered for Japan’s Earthquake-Prone Environment

 • The UniC DG500 employs a pressurized module design and shock-absorbing cabinet structure to withstand continuous aftershocks.

 • Successfully deployed in industrial projects in Kagoshima, in which the installation layout is optimized to fully comply with the requirements of the fire department.

Maximizing Economic Value: Extended Lifespan & Superior Adaptability

One of the top priorities in energy storage—particularly in commercial & industrial applications—is maximizing economic returns. Users seek solutions that not only extend operational lifespan and reduce total lifecycle costs but also adapt to complex environments for optimal financial performance.

 • Ultra-Long Cycle Life: Kunlun cells deliver over 15,000 charge-discharge cycles, maintaining 80% State of Health (SOH) for over 20 years, significantly reducing replacement frequency and maintenance costs.

 • Wide Temperature Adaptability: Designed for extreme climates, Kunlun cells operate reliably from -20°C to 60°C, ensuring uninterrupted system performance year-round—from scorching heat to freezing cold.

Innovative Product Lineup: Comprehensive Coverage, Industry-Leading Technology

At the event, Ampace will unveil a four-segment product portfolio, all designed with high energy density, long lifespan, and low maintenance as core advantages:

 1. Residential Energy Storage (RESS) - PR-S1:

 • Modular stackable design, expandable from 3.3kWh to 23.3kWh for flexible customization.

 • IP55-rated protection for Japan’s rainy climate.

 • -20°C discharge capability ensures emergency power supply in cold regions like Hokkaido.

 • Customizable installation components to meet Japan’s seismic and specialized mounting requirements.

 2. C&I Energy Storage Flagship - UniC DG500:

 • 532.48kWh per cabinet, expandable up to 4.2MWh with 8-cabinet parallel integration.

 • Powered by Kunlun 2.0 GT40 cells, it can have a service life of up to 20 years.

 3. High-Power UPS - PU100:

 • 6C discharge rate, enabling rapid backup within 10-15 minutes.

 • 70% space savings compared to traditional lead-acid batteries.

 • Certified for UL9540A and other global safety standards, ensuring uninterrupted data center operations.

 4. Portable Power Station - Andes Series:

 • Covers 266Wh, 584Wh, and 1462Wh capacities.

 • Andes 1500 delivers 1462Wh capacity and 3600W peak power, ideal for post-disaster emergency power supply.

 • Combines lightweight durability, silent operation, broad temperature adaptability, and fast charging—making it a top choice for Japanese households’ emergency preparedness.

TDK’s Localized Expertise: Full Lifecycle Support from R&D to Decommissioning

Ampace’s deep collaboration with TDK offers Japanese customers a dual-layered assurance of technology and service:

 • Certification & Testing Support: TDK provides testing, multi-purpose combustion testing laboratories, and other facilities to ensure JET (Japan Electrical Safety & Environmental Tech. Lab.) certification.

 • Rapid Response System: A local warehouse network ensures fast technical support, while expert teams provide end-to-end services from design and installation to end-of-life (EOL) management.

Accelerating Japan’s Carbon Neutrality with Safe & Reliable Energy Storage

Jason Zhu, President of Ampace Energy Storage Division, emphasized:

“Japan is a cornerstone of our global strategy. Beyond providing products, we are committed to building a ‘zero-distance’ service ecosystem with TDK, delivering safe and reliable energy storage solutions to accelerate Japan’s carbon neutrality goals.”

As the world transitions toward clean energy, Ampace is driving innovation through technological excellence and localized service solutions, redefining the value of energy storage and powering a greener future for humanity.
