battery protection board Cell monitoring system
 

 

1. We can provide seplos CANBUS/RS485 24V/48V 50A/100A/150A/200A Lifepo4/NCM BMS,for prismatic or Cylindrical lithium battery pack

2.We can provide two kinds of BMS boards with different communication modes, one is BMS using CANBUS communication protocol and the other is BMS using RS485 communication protocol, so that customers can have more flexible choices

3.Our BMS can support up to 16 units in parallel operation.

4.The main functions are: CANBUS communication,RS485 communication,Passive balance,Individual cell over voltage protection,Over (under)voltage protection,temperature protect,over charge(discharge) protection, over current protection, Short circuit protection etc.

Attention: when we want to view the battery pack parameters through the battery parameter monitoring software, we need to use the Rj45 to USB Adapter to connect the battery pack to the computer. We recommend that you purchase an Rj45 to USB Adapter from us.Adapters purchased from the market may not work properly due to the definition of the hardware

 BMS Functions

Monitoring:

Voltage: total voltage, voltages of individual cells, minimum and maximum cell voltage.

Temperature: environment temperature, temperature of cells and BMS PCB.

State of charge: indicate the charge level of the battery.

Current: current in or out of the battery.
 

 Communication:

CANBUS communication

Our BMS can support up to 16 units in parallel operation.

RS485 communication(RS485 can be customize)
When we want to view the battery pack parameters through the battery parameter monitoring software, we need to use the Rj45 to USB Adapter to connect the battery pack to the computer. We recommend that you purchase an Rj45 to USB Adapter from us. Adapters purchased from the market may not work properly due to the definition of the hardware
 

Protection:
Over voltage protection 
Capacity protection
Pre-chargeing function
Current limiting
Under voltage protection
Charge, discharge and ambient temperature protection
Charge and discharge over current protection
Charge current limitation
Short circuit protection
 
Custom function:
Heating function

The BMS with RS485 communication has a built-in RS485 protocol, please confirm with the salesman before buying what you need is that one RS485 protocol:

The default is the Pylontech RS485 protocol

Please ask your inverter supplier for the protocol define.And sent it ti us,we'll help confirm that

Q:Does your BMS have current balance?
A:yes,We have the current passive balance function, the passive balance function module is integrated on the BMS board, do not need external balance device.
