Control Unit and Battery Cabinet

What is a Battery Control Unit (BCU)?

Since battery cells require a proper working and storage temperature, voltage range, and current range for lifecycle and safety, it is important to monitor and protect the battery cell at the rack level. battery control unit (BCU) is a controller designed to be installed in the rack to manage racks or single pack energy.

What is a bus cabinet?

The bus cabinet serves as the DC-side bus control unit of the energy storage battery system, connecting the high-voltage box and the storage converter. It integrates the power pool system (stack), optional fuses or circuit breakers, a three-level Battery Management System (BMS/ESMU), and a UPS power supply.

Can a central controller be used for high-capacity battery rack applications?

These features make this reference design applicable for a central controller of high-capacity battery rack applications. Currently, a battery energy storage system (BESS) plays an important role in residential, commercial and industrial, grid energy storage and management. BESS has various high-voltage system structures.

How to protect a lithium battery energy storage cabinet?

At the same time, setting the charging and discharging parameters, configuring the safety and protection settings, and protecting the lithium battery energy storage cabinet from potential dangers such as overcurrent, overvoltage, and overtemperature are necessary.
