ESS-CABIN Energy-storage PCS booster integrated cabin

Overview

The energy storage converter and step-up integrated cabin comprises a converter system, a transformer (step-up) system, a PV system and a charging system, and manages energy conversion between the storage batteries, the PV array and the grid. During off-peak periods, grid and PV energy can be stored in the battery units; during peak periods or a grid outage the cabin acts as a power source. This effectively addresses the variability and time-of-day dependence of wind and solar generation, improves the utilisation of renewable energy and provides peak shaving and valley filling for the grid.

The cabin also integrates an EV charging point, providing a stable, efficient and reliable charging supply for electric vehicles.

Features

• The integrated cabin consists mainly of an HV/LV unit, a local monitoring unit, a bidirectional energy storage converter unit, an access-control unit, a cooling unit, a fire-protection unit and a lighting unit. It combines DC-to-AC inversion with AC step-up in one product, integrates the energy storage system on industrial design principles, and uses a standard 10 ft / 20 ft prefabricated cabin structure that is neat in appearance, easy to install and simple to commission. The design is suited to high-altitude, severe-cold, coastal, desert and other complex, harsh environments.
• Cell-level intelligent temperature control improves system efficiency and battery cycle life. The modular design provides automatic balancing management, which simplifies system expansion and control. Multiple condition-monitoring functions with a tiered linkage design fully safeguard the battery system.
• The PACK-level fire-protection design gives early warning at the initial stage of cell thermal runaway and locates the fault precisely.

Applications

• Peak shaving for industrial consumers
• PV plants with storage and microgrids
• Backup supply during grid outages
• EV charging hubs
