With these new devices, a system designer can expect that the system will be as efficient, reliable, and protected as possible. At ABB we offer an extensive line of higher rated DC components from 600 VDC to 1500 VDC, designed to meet today’s utility BESS requirements. UL-rated 480 VAC to 1000 VAC and 600 VDC to 1500 VDC components are used in the following BESS system components:

Battery Management System (BMS)

• DC disconnect switches to isolate the battery banks

• DC circuit breakers to help protect the system in case of an overcurrent or short-circuit condition

• DC contactors used to remotely switch battery banks on and off, including isolation

• DC surge protection devices (SPDs) used to protect against voltage spikes and lighting strikes

• DC insulation monitors for identification of leakage current events

• Current Monitoring Systems (CMS) to monitor battery operating conditions, including amperage and voltage levels. Power quality can also be monitored

Power Conditioning System (PCS) or inverter/converter

• AC circuit breakers to help protect the AC side of the system in case of overcurrent or short circuit condition (480 VAC to 1000 VAC)

• AC surge protection devices for protection against voltage spikes and lighting strikes on the AC side of the system

• DC contactors to remotely switch on and off and isolate the DC side of the system

• DC surge protection devices to help protect against voltage spikes and lighting strikes on the DC side of the system

Energy Management System (EMS)

• Ground fault protection devices to help protect against ground faults

• Miniature circuit breakers to help protect auxiliary components

• Disconnect switches to isolate the EMS from other system components Energy Storage Module (ESM)

• Ground fault protection devices to help protect against ground faults

• DC disconnect switches to isolate the system

• Miniature circuit breakers to help protect auxiliary components

Battery side (DC)
