BCK LiFePO4 Smart Battery Control Kit, Mini Batteries Management System

Description:

The mini battery management system is built with 1 or up to 4 smart battery packs in series and Battery Control Kit(BCK,optional).

Main Feature

1. Up to 48V system can be built with battery packs.

2. High continuous discharge current is available.

3. BCK can balance the battery packs.

4. BCK can read and display the information of battery system.

Main Function

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

2. Measure the charge and discharge current of the battery system.

3. Calculate the SOC of the system.

4. Control system temperature.

5. Record running and fault data of the system .

Applications:

Through RS485 cables BCK can collect voltage, current, temperature and SOC data from battery packs. BCK can also balance the battery packs during charging. The system is suitable for small scale power system, such as

1. Mini motor car

2. Small medical equipments

3. Other small power system

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), 

Discharge Interrupt

When the batteries are discharged to the under-voltage protection point,

 BMU will attempt to alert the host to inhibit discharge. If discharge continues 

beyond this warning, the BMU will request that the main contactor open or 

can open it itself.

Insulation measurement

The BMU will check to make sure the battery module is sufficiently isolated

 from the chassis before and after the main contactor is closed.

Pre-charge circuit

To limit the inrush current into the systems capacitors, a pre-charge resistor

 is connected to B+ before the main contactor is closed.  

This also prevents arcing and pitting across the contact tips.  

The BMU will close an auxiliary contactor to place a resistor in line with B+.

  After 2 seconds, the main line contactor will close.

Inter-module Balancing

Compensates slight capacity imbalance between different batteries 

when charging.

Intra-module Balancing

Compensates slight capacity imbalance between different cell-blocks 

within one module while charging.

Size

100 mm x 60 mm x 27 mm

Weight 

Approximately 20g

Main Features

1. Interchangeable design to replace Lead Acid Battery .

2. Built-in PCM to prevent from over-voltage, under-voltage, over current and over-temperature.

3. Up to 4 battery packs can be connected in series to reach 48V.

4. Balance each cell block. Easy instal
