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

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. |

Competitive Advantage:
1. Intrinsic Safety from LiFePO4 Material
Lithium ion battery made with O'CELL LiFePO4 cathode material can pass the safety tests easily such as nail test, 3C/15V over-charge test, etc.
2. Better Shelf Life
The shelf life of lithium ion battery can be measured by capacity retention at full charge state. Usually, the capacity loss of self-discharge can be divided into recoverable and irrecoverable capacity. O'CELL LiFePO4 has excellent shelf life. The self-discharge rate is about 3% per month, the capacity can recover up to 98% after long time storage.
3. Good Rate Performance
The discharging voltage platform of O'CELL LiFePO4 battery is flat. LiFePO4 power battery has good rate performance, the capacity @20C is more than 95% of 1C discharging capacity at room temperature. The maximum temperature rise is less than +20ºC.
4. Wider Operation Temperature
1.Operation temperature range:-20~+60℃;
2.Storage temperature range:-40~+60℃;
3.The capacity at -20℃ is more than 70% that of +25℃;
4.The capacity at +60℃ is more than 98% that of +25℃.
5. Excellent Cycle Life
During charging and discharging, the cathode (LiFePO4) and anode (graphite) in battery cause little changes of total volume. The small volume change will bring little internal stress to the separator, which will be helpful for the battery safety and cycle life. After 3,000 cycles, the residual capacity of O'CELL LiFePO4 battery is more than 75% of that of nominal capacity.
