Solar Energy Storage BATTERY System 225S 720V 400A Master Slave BMS
Battery management system (BMS) is technology dedicated to the oversight of a battery pack, which is an assembly of battery cells,
electrically organized in a row x column matrix configuration to enable delivery of targeted range of voltage and current for a duration of time against expected load scenarios.
The oversight that a BMS provides usually includes:
- Monitoring the battery
- Providing battery protection
- Estimating the battery’s operational state
- Continually optimizing battery performance
- Reporting operational status to external devices
Every Battery requires a BMS!
By 2022, global battery manufacturing capacity is set to cross 400 GWh.
The huge demand for batteries is driving the need for smarter battery management.
A battery management system is the key to reliable and efficient functioning of the battery.
Hunan Group Control Energy Technology Co., Ltd.(GCE) is a high-tech company specializing in the research and development of BMS and lithium battery peripheral equipment.
4S to 24s low voltage software BMS has a wide range of uses, rich product interfaces,
strong scalability and secondary development compatibility;
30s to 75s BMS adopts master-slave integrated design and relay solution to meet the lithium battery demand of multiple strings of small capacity batteries. Greatly reduce the use cost of users;
60s-270s adopts master-slave three-level architecture, which can meet the series and parallel requirements of high-capacity single lithium batteries within 1000V.

| 1. Advanced Battery Management System --- The highly integrated battery management
system enables seamless monitoring.
2. perfect self-test and operational status detection, with HMI display, system
operation information at a glance.
3. perfect and reliable system control and protection strategies to fully protect the
battery safety, extend the life of the battery escort.
4. Modular design, configurable, scalable --- flexible combination of multiple energy
storage unit can be expanded to a larger energy storage system, the maximum can support 272 (lead-carbon battery 400) battery series.
5. Rich communication interface --- multiple RS485, CAN, Ethernet, dry contact input and
output interfaces, support for most of the market with PCS, monitoring server communication.
6. Flexible communication interface protocol --- The company comes with the company's
communication protocol, but also according to customer needs to adapt to PCS of different manufacturers.
7. Capacity is large --- Built-in large-capacity memory chips can store a large number
of key operational data, but also can install an SD card for offline access. 8. PCS has a protocol control function, the choice of circuit breaker version .
9. PCS without protocol control function, the choice of contactor + breaker version.
10. Automatic circulation control and automatic parallel machine off-line control, can be easily parallel battery. (Model suffix selection D). |
