Coremax 100kw Highvoltage Lithium Storage Systems Target Industrial Efficiency

Coremax's 100 kW high-voltage lithium battery energy storage system (BESS) uses a 768 V DC architecture to combine power conversion and battery storage for solar generation and industrial power applications. The integrated design is intended to support efficient energy dispatch and power reliability as renewable generation increases on the grid. The system's technical features, operating modes and safety management are outlined below.

Technical architecture and operating logic

The BESS integrates a power conversion system (PCS) with battery packs and supports configurations ranging from 100 kWh to 200 kWh. An energy management system (EMS) controls power flows to address the intermittent output of photovoltaic generation and differences in grid electricity tariffs.

Multiple operating modes

The system can operate in three primary modes, depending on site conditions and tariff structures:

• Self-consumption optimization: The system stores surplus electricity during peak photovoltaic output and releases it when solar generation is insufficient, increasing energy self-sufficiency.
• Peak shaving: Charging during low-tariff periods and discharging during high-tariff periods can reduce industrial electricity operating costs.
• Uninterruptible power supply (UPS) function: During a grid fault, the system can switch within milliseconds to maintain supply to local loads. With a 200 kWh configuration, it can sustain full-load operation for more than two hours.

In all modes, the EMS coordinates storage and discharge activity to match generation, load and tariff conditions.

Key specifications

The published specifications for the 100 kW system are summarized below.

Intelligent management and safety

The system is designed to address safety and controllability across the full lifecycle of energy storage, not only the storage function itself. Its battery management system uses a three-tier architecture comprising BMU, CMU and GPC, providing high-precision signal detection and active balancing to support consistency across battery packs.

The system also incorporates intelligent thermal management and redundant power supply design. High-performance DSP and software control are used to improve operating efficiency while seeking to minimize fault risk.
