High Voltage BMS Battery Management System For Electric Vehicles / Golf Carts
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

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.
