BMU Lithium Ion Batteries, LiFePO4 Battery Management System / Units

 

Description:

The battery management system is comprised of master module (BMU), slave module (PCBA), battery 

modules, contactor and LCD (optional). Up to 128 modules can be connected in series and parallel to build 

a whole system. The whole system voltage can reach 700V at most.

 

Main Feature

Beside the basic functions such as over-voltage, under-voltage, over-current, over-heat and balancing, 

O’CELL BMS owns the following features.

1. Master-Slave architecture makes the system flexible.

2.Levelalarm makes maintenance easier.

3. CAN2.0 and industrial level electronic components makes system reliable.

4. Contactor makes high rate charging and discharging feasible.

5. Periodic insulation measurement makes personnel safer .

6. IP56 design makes system suitable for wider application.

7. Host can control the system easily.

 

Main Function

1. Measure the voltage of the battery in series and the whole system.

2. Detect the charge/discharge current of battery system.

3. Calculate the battery system's SOC.

4. Measure the insulation of battery system.

5. Control the temperature of battery system.

6. Communicate with host or LCD screen.

7. Communicate with charger.

8. Record the operation and failure data .

9. Data storage and monitoring by PC.

 

Applications:

1. Eco battery power system for light electric vehicle, HEV, EV, etc.

2. Energy storage system for solar, wind or solar-wind system, etc.

3. Backup power system for telecom base station, communication equipments, power grid, banks, UPS, etc.

Comments

RS-485 Communication

RS-485 Communications is used to communicate with the battery modules. 

CAN interface

 

CAN interface will be used to communicate with the host or the charger.

Charge Disconnect

 

When the battery modules are fully charged, they will communicate with the 

BMU and the BMU has the ability to turn off the charger or open the charger 

main contactor, interrupting current flow. 

Analog/Digital 

Communications

 

In case the host controller doesn’t have a CAN interface, the BMU 

communicates with the host via analog/digital signals. These signals include: 

Outputs – SOC (A), disable regen(D), early warning(D), BMU fault(D)

Inputs- 12V ignition (D), vehicle fault (D),
