Solar Battery Management System Lithium Ion Rechargeable Lithium
Polymer Battery
Features:
(1) SPI daisy chain structure
The BIU and BMU are connected by a daisy-chain topology, and the
main board and the slave board can collect data of a total of BIU
(16~48)+BMU*n string cells.
(2) Single cell voltage collection
The BIU and BMU collect the individual cell voltages through a
voltage acquisition module.
(3) Temperature collection
The BIU and BMU collect the temperature of each battery module in
the module through the NTC temperature sense.
(4) PACK total voltage detection
The BIU has a PACK battery pack total voltage detection function.
(5) CAN communication function
Each BIU has 3 CAN communications.
CAN0, used by the BIU to communicate with the CSU and obtain the
current total current.
CAN1, used by the BIU to communicate with the charger.
CAN2, used by the BIU to communicate with the vehicle VCU/MCU to
receive commands and status information of the VCU/MCU.
(6) RS485 communication function
It can be connected to an external LCD display with 485 bus via 485
bus for power, voltage and current display, and program update is
also possible.
(7) SOC, SOH, SOP calculation
The BIU calculates SOC and SOH, SOP based on parameters such as
total current, total voltage, and voltage and temperature of the
individual cells.
(8) Battery display
The BIU calculates the remaining power and displays it on the LCD,
vehicle instrumentation, and calibration software.
(9) Drive relay / fan
The BIU controls the power-up and power-down of the load through
the high-side drive.
(10) pre-fill module
When the BIU controls the load to be powered on, the main circuit
load is pre-charged by the pre-charge module, and then power-on
after completion. AUX+ can be used as a control for external
precharge.
(11) Onboard insulation monitoring
Real-time monitoring of the high-voltage positive end to the car
shell and the high-voltage negative end to the insulation
resistance of the car shell, when the threshold is below a certain
threshold, an alarm signal is issued.
(12) Input signal detection
The BIU judges the working state and charging state of the vehicle
by detecting the vehicle KeyOn wake-up signal and the charger
wake-up signal.
(13) Key information is saved after power down
When the BMS detects that the system is powered down, it stores the
key data of the system, such as the highest and lowest voltages and
corresponding positions, SOC, current, and historical faults, in
the FLASH of the MCU for storage.
Applications: new energy vehicles, electric vehicles, golf carts,
sightseeing cars, sweepers, power

Product name | BMSIntegrated BMS battery management system | system structure:
The battery management system is an important part of the electric
vehicle system. The BIU series integrated BMS is designed for
medium and low speed vehicles, using automotive grade components
and IP54 protection. The product has strong scalability, which can
complete the collection, management and control functions of a
single box. It can also externally extend the application scenario
of BMU to adapt to multiple cabinets. It is widely used in
low-speed vehicles to meet the system management requirements of
automotive-grade power battery packs. It is suitable for ternary
lithium-ion batteries, lithium iron phosphate, lithium manganate,
titanium. A secondary battery such as lithium acid having a cell
voltage in the range of 0 to 5V.
This product is mainly composed of a battery integrated management
module BIU (BIU), display screen, shunt, wiring harness and other
accessories. BIU can separately collect and manage 16/32/48 string
batteries, and support up to 10 16-string slaves. Expansion. The
system is extended with a daisy-chain topology to obtain battery
sampling information in real time. When the electric vehicle system
works, BIU communicates with the vehicle controller, intelligent
charging device, instrument and other equipment through the CAN bus
to display the status information, power, SOC, etc. of the battery
pack. After the vehicle controller reads the BMS data, the motor is
controlled by the intelligent motor controller. BMS can also
communicate with on-board chargers and fast charging stations, and
has connection confirmation functions such as charging port
temperature detection, CC, CP, CC2 and other national standards. |
