Energy Storage Systems: Utility, Commercial, and EV Solutions

We design scalable energy storage system architectures at every level, from battery cell connections to complete container integration. Our solutions optimise voltage, energy capacity, and system reliability to meet your manufacturing requirements.

The three-layer battery management system (BMS) architecture comprises a battery array management unit (BAMU) as the primary controller, a second-level battery cluster management unit (BCMU), and a third-level battery monitoring unit (BMU). It delivers high-precision analogue signal detection, fault alarms, data logging, battery protection, parameter configuration, cell balancing, state-of-charge calibration, and high-quality communication with other system components.

We support both centralised and modular PCS topologies, from high-power central PCS units to distributed string PCS architectures. Additional DC-DC converters can be integrated at rack (RLO) or module level (MLO) to optimise charge/discharge cycles. AC/DC string topologies are built into the battery rack.

Central PCS: integrating into the battery cabinet or delivering as a stand-alone solution

DC/DC optimiser topologies: module- and rack-level

Cell performance is highly sensitive to temperature, making thermal design a critical factor in battery energy storage systems. The optimal thermal strategy depends on:

1. Frequency of use
2. Application type (grid-forming or grid-following)
3. Installation conditions (altitude, climate)
4. Operational and maintenance costs (OPEX)

We develop custom thermal management solutions, including air, liquid, or hybrid cooling, as well as integrated heating systems for low-temperature environments. PCS can be installed at either the container or rack level, depending on design requirements.

Each lithium-ion cell in a battery pack stores significant energy, meaning any malfunction can jeopardise the entire BESS and nearby equipment. Robust safety design is essential at every system level to prevent damage and ensure operational reliability.

To protect against faults, BESS incorporate key circuit protection elements, such as fuses, DC breakers, and contactors. They enable rapid, controlled shutdowns during abnormal events, minimising risk and downtime.
