GCE 768V 125A 4U master BMS lithium BMS relay contactor protection smart balancing high voltage bms
GCE high voltage bms Diagram:
Battery Management Systems (BMS) are the key to the safe, reliable and efficient functioning of the lithium-ion batteries.Especially When use a high voltage bms. It is an electronic supervisory system that manages the battery pack by measuring and monitoring the cell parameters, estimating the state of the cells and protecting the cells by operating them in the Safe Operating Area (SOA).
High Voltage (HV) battery packs have a large number of lithium ion cells connected in series and parallel to build up the total voltage and capacity of the pack. All battery packs managed by a high voltage bms system. For example, a HV battery pack of a ESS rated for 768V, 50kWh built of LiFePo4 3.2v 100Ah battery cells will have about 240 cells in series , taking the total cell count to 240pcs.
GCE high voltage BMS features:
※ ※Advanced battery management system---The highly integrated battery management system
can realize seamless monitoring.
※ Perfect self-checking and running status checking function, with HMI display screen,
system running information is clear at a glance.
※ Complete and reliable system control and protection strategies, comprehensively guarantee
battery safety, and escort to extend the life of battery packs.
※ Modular design, configurable and expandable---multiple energy storage units can be
flexibly combined and expanded into a larger energy storage system.
※ Abundant communication interfaces---multiple RS485, CAN, Ethernet, dry contact input
and output interfaces, supporting communication with most PCS and monitoring servers on the
※ The communication interface protocol is flexible---the factory comes with the company's
communication protocol, and it can also be adapted to the PCS of different manufacturers according
to customer needs.
※ The built-in large-capacity memory chip can store a large amount of key operating data, and
an SD card can be added to realize battery historical data storage
※ Automatic circulation control and automatic parallel/offline control can easily realize the
parallel connection of battery packs.
