4S~300S master slave multiple series BMS for household energy storage, commercial energy storage inverter high voltage BMS system

Description

Introduction of high-voltage energy storage master-slave BMS system
this BMS system can Manage the entire battery pack, collect the battery’s total voltage, total current, and ctemperature, diagnose whether the system has abnormal faults, and which was used for battery charge and discharge management and safety management, specially for multiple BMUs, and estimate the SOC, SOH, SOP, etc. of the battery pack based on BMU data.
The system supports management of up to 32 BMUs and up to 300 battery strings.
It has 6 channels of high-side drivers, 2 channels of bottom-side drivers, and 4 channels of DI acquisition, which can drive relays and fans.
Supports battery pack total voltage collection, and has two total voltage back-steps, with a collection range of 20~1000V.

The system supports 9~36V power supply, and the default is 24V power supply.
The system supports management of up to 32 BMUs and up to 300 battery strings.
It has 6 channels of high-side drivers, 2 channels of bottom-side drivers, and 4 channels of DI acquisition, which can drive relays and fans.
Supports battery pack total voltage collection, and has two total voltage back-steps, with a collection range of 20~1000V.
The master control has 4 channels of temperature acquisition, and the slave control has 6 channels of temperature acquisition.
It has 2 channels of CAN, 3 channels of RS485, and 2 channels of UART communication interfaces, which can communicate with external screens, Bluetooth, and inverters.
It has a variety of fault detection functions, such as overvoltage, undervoltage, overcurrent, overtemperature, insulation, cell disconnection, temperature disconnection, etc.
Various failure and protection functions such as abnormal total voltage and abnormal current.
Support RS485 and CAN upgrade.

Our BCMU Module and BMU slave module should applied together with this high voltage box to work with ,then it can construct a full set of Management system

A : Master Controlling BMS Module :

The high-voltage energy storage battery management system BCMU01 is mainly used in household energy storage, commercial energy storage and other application fields. This system is a distributed two-level architecture energy storage system. The system is mainly divided into Pool management master control unit (BCMU), battery management unit (BMU). The system can detect the cell voltage, cell temperature, current, total voltage and other data of the battery in real time, and calculate the remaining capacity in real time.
Measure SOC, estimate the battery monitoring status SOH, calculate the current cell power status SOP, effectively manage the safety of the lithium battery system, and realize PCS information through the CAN/RS485 communication interface Interaction.
