Chapter 1 Product Applications
BMS is an important part of EV system. Adopting automobile grade components, JDI BI
series can be well extended and widely applied to pure electric and hybrid vehicle, which not
only can detect, manage, control the batteries in single box, but also can be extended through
BMU to manage batteries in several boxes. The series fully meet the systematization
management requirement of the automotive-grade power battery pack. The series is suitable
for LiCoMnNiO2, LiFePO4,Ni-MH, super capacitor and other 0~5v cell.
The product is composed by a Battery Integrated-management Unit (BIU), a display, a
current sensor/diverter, and cables. The series include BI5116, BI5132 and BI5148. Each
BIU can collect and manage 16/32/48 cells, and can be extended to manage 160 cells at most.
The system acquires real-time battery information through Daisy Chain Topology (DCT).
BIU communicates with VCU, intelligent charger, instrument and other device through
CAN-bus. The display shows the real-time information of state, power, SOC etc.VCU
controls the motor through intelligent motor controller after reading BMS information. BIU
can also communicate with intelligent charger and charge pile. There are temperature
measurement of charging interface, CC, CP, CP2 and other required functions

Notice: BIU have to be installed into the negative side of battery pack when using BIU +BMU
combination. e.g: when using BI5116+BM5116 to collect a 32 cells pack, the cell of total negative is
B1,the cell of total positive is B32.Then BI5116 should collect B1~B16,and BM5116 should collect
B17~B32.It’s very important to connect correctly, or the total voltage and insulation detection will be
influenced.

4. Software introduction
4.1 Introduction of software
4.1.1Main interface
Click “Overview” to enter the main interface
It shows the basic information of batteries and BMS, the function windows of upper computer
and system error information.
Hall current sensor

a) Upper computer function buttons: Overview / Cell information/ Calibration /Upgrade
b) BMS power and charger information
KeyOn means the power is from DC-DC converter during discharging.
Wakeup voltage means the power is from charger auxiliary power supply during charging.
The voltage of VCC should be equal to Keyon voltage and Wakeup voltage. Please contact
us if the voltage difference over 3V.
Charger output voltage/current: BMS get the charging data sent by charger (through CAN-
bus). The data should be same to charger display.
c) Alarm status，Green---Normal; Orange—Alarm; Red ---Major fault
4.1.2Cell information
Click “Cell information” to enter the batteries information interface.
Cell information interface— display cell voltage and temperature information.

Calibration interface—Click “Calibration”to enter calibration interface
Calibration interface—Function area of BMS parameter configuration, users can configure
parameters and simulated failure on this interface.
a) Function area: click the button to enter the corresponding parameter configuration interface
b) Parameter configuration interface: system supports manually modification and batch import
parameters.
c) Import—Import the current parameters (“.json”) to BMS, click Calibration, and then click
Flash.
d) Export—Export the BMS data to a “,json” file, it can be used to modify batched parameters.
e) Read—Read the BMS existing parameters. Default: automatic reading.
f) Calibration—It’s necessary to click “Flash” after modifying the parameters. Otherwise, the
new parameters are invalid.
g) Flash—Insure to click “Flash” after calibrating parameters. Otherwise, parameters will reset
to the parameter after BMS restart.
h) Parameters display and modifying. Double click the data, and modify it.
i) eg: modifying the SCO to 30%, double click “65535”→enter 30→click “calibration”→click
“flash”.
4.2 Upgrade the software
Open Upper computer software, click”Upgrade”→click “Burn”→choose the program→
click “Open”
