Dyness DH2150Y-BC: Mobile Energy Storage and Charging Without Limits

As electrification accelerates across transport, construction, mining and logistics, the demand for flexible, infrastructure-free energy is growing rapidly. Fixed charging points and grid connections are not always available where power is needed most. Dyness answers this challenge with the DH2150Y-BC mobile liquid-cooled storage and charging container, a high-capacity, plug-and-play solution designed to bring energy exactly where it is required.

The DH2150Y-BC combines energy storage and charging in a single mobile platform, enabling rapid deployment across multiple sites without the need for permanent infrastructure. Powered by grid electricity, wind or photovoltaic generation, the system transports energy directly to the point of use—making it ideal for construction sites, mines, ports, bus depots, EV fleets and temporary power applications.

High-Capacity Mobile Storage in a Standard Container Format

Built in a 20-foot high-cube container, the DH2150Y-BC delivers a total system capacity of 2.15 MWh, offering utility-scale storage in a transportable format. The system is engineered for demanding environments, operating reliably between –20°C and 50°C, with IP55 ingress protection and C3 corrosion resistance to ensure long-term durability in outdoor and industrial conditions.

Thanks to its liquid-cooled architecture, the battery system maintains stable performance even under high load and fast-charging scenarios. This thermal stability not only improves efficiency but also extends battery lifespan and ensures predictable operation throughout daily cycles.

Integrated Storage and Charging for Maximum Flexibility

At the core of the DH2150Y-BC is Dyness’ DC-coupled storage and charging design, creating a compact, space-efficient system that overcomes common site limitations such as restricted parking or temporary layouts. Energy is distributed dynamically across charging points, allowing multiple vehicles or machines to be served efficiently from a single mobile unit.

The container is equipped with a self-developed storage and charging operation management platform, supported by an AI-powered cloud system. This enables precise control, real-time monitoring and optimized energy dispatch, ensuring charging power is allocated exactly where it delivers the highest operational value.

Designed for Reliability, Safety and Emergency Power

The DH2150Y-BC is built with cluster-level independent management, preventing system-wide downtime caused by a single component failure and minimizing battery inconsistency risks. This architecture is particularly valuable for mission-critical operations where uptime is essential.

Safety is integrated at every level. The system includes pack-, cluster- and water-based fire suppression, advanced venting design and three-stage circuit breaking, delivering robust protection even in high-stress operating environments. In addition to charging applications, the DH2150Y-BC supports off-grid emergency backup power, making it a reliable solution for disaster response, temporary grid support and distributed energy supply.

Plug-and-Play Mobility with Simple O&M

Mobility is at the heart of the DH2150Y-BC. The container is designed for true plug-and-play deployment, allowing operators to move, connect and activate the system quickly across different sites. Its modular internal layout simplifies installation, servicing and future upgrades, while online monitoring and remote O&M tools reduce maintenance effort and operational costs.

By eliminating the need for fixed infrastructure, the DH2150Y-BC unlocks new revenue models for energy providers and fleet operators—turning energy into a mobile asset that follows demand instead of waiting for it.
