As the core of modern automotive battery technology, BMS can monitor the voltage and current of the battery in real time, accurately evaluate the state of power, and help users rationally arrange the use of the battery. At the same time, the BMS system can optimize the charging and discharging process, improve the efficiency of the battery and reduce the energy loss. And by balanced management of the charging state of each individual battery in the battery pack, BMS can effectively prevent overcharge or undercharge, thereby extending the overall life of the battery. In order to promote the application of BMS system, the company has launched NXP S32K312 MCU, MC33772C battery control IC, FS2303B SBC chip, TJA1443AT CAN chip, PCA85073A clock chip as the core. Automotive 12V with integrated Molex 5600201020 connector, onsemi NV24C64LV EEPROM, Vishay WSLP5931 high-power resistor, as well as AnSE Semiconductor BUK7S0R5-40H MOSFET and SGM8752-1Q comparator BMS application solution.

The S32K312 is part of NXP's S32K3 family of automotive general purpose microcontrollers. The product is based on ARM? Cortex? -M7 kernel supports single-core, dual-core, and lock-step kernel configurations. The S32K3 series is scalable in terms of the number of cores, memory and peripherals, is ISO26262 compliant, offers advanced functional safety, information security and low power consumption, and is suitable for harsh body, area control and electrification applications.The MC33772C used in the AFE module is NXP's battery control IC designed for automotive and industrial applications, which supports monitoring and management of up to six strings of batteries. At the same time, the IC is capable of analog-to-digital conversion of differential battery voltages and ensures highly accurate measurements through up to 256 average grades. In addition, the MC33772C also integrates multiple functions such as current acquisition, coulomb counting, and temperature measurement, which can achieve comprehensive monitoring and management of battery status.
In terms of power supply, the scheme uses FS2303B system basic chip (SBC). The chip has unique design and performance advantages to meet the stringent system stability and safety requirements of the latest generation of automotive electronic control units (ECUs), and fully adapt to their system and safety characteristics. In addition to providing a stable power supply, the FS2303B also integrates a variety of functions such as CAN transceiver, LIN transceiver, high edge driver and functional safety module. With disposable programmable memory (OTP), users can turn on specific functions to meet the needs of a diverse range of automotive applications. In addition, the chip is highly flexible, offering multiple device version options in terms of output voltage setting, operating frequency, power-on sequence, and input/output configuration, which can be flexibly adapted to a variety of application scenarios.
The PCA85073A is a CMOS1 real-time clock optimized for low power consumption that allows the clock to be fine-tuned via the offset register for more accurate timing and calibration.
In addition, the solution also uses the TJA1443AT CAN transceiver to help achieve efficient and reliable on-board network communication, ensuring real-time data transmission and processing of the battery management system.
