On May 15, 2025, Da Da Da Da Da Da Da Shi Ping Group launched a portable energy storage BMS application solution mainly based on Jingfeng Mingyuan and Jiehuate products. Da Da Da Da Da Holdings, an international leading semiconductor component distributor dedicated to the Asia Pacific market, announced that its subsidiary Shi Ping has launched a portable energy storage BMS application solution mainly based on Jingfeng Mingyuan (BPS) LKS32MC453 MCU and JOULWATT JW3376 AFE chip, JW3330 high edge driver, JWH5140F single-chip step-down switch regulator, JW7806 LDO regulator, supplemented by Silicon Magic SDN10N3P5B-AA and SDN10K018S2C N-MOSFET, as well as Nanochip Micro (NOVOSENSE) NSPGS2 pressure sensor as peripheral devices. Can provide BMS application solutions.

In recent years, with the rise of outdoor lifestyles and the increasing demand for emergency power sources, portable energy storage products are becoming the core infrastructure for outdoor activities, emergency disaster preparedness, household electricity use, and other scenarios due to their flexible, convenient, efficient, and reliable characteristics. In the field of portable energy storage, the Battery Management System (BMS) is a key component that ensures the safe operation of batteries and optimizes energy utilization efficiency. Its performance directly determines the safety and efficiency of the equipment. In response to the trend of portable power supplies, Da Da Da Da Da Da Da Shi Ping has launched a portable energy storage BMS application solution, which mainly includes the Jingfeng Mingyuan LKS32MC453 MCU, the Jewate JW3376 AFE chip, the JW3330 high edge driver, the JWH5140F single-chip step-down switch regulator, and the JW7806 LDO regulator, supplemented by the Xinmai SDN10N3P5B-AA and SDN10K018S2C N-MOSFET, as well as the nano core micro NSPGS2 pressure sensor as peripheral devices. It has multiple protection functions and can monitor and manage the battery status of portable energy storage devices in real time and accurately.

The main control of this scheme adopts the high-performance and low-power MCU LKS32MC453 from Jingfeng Mingyuan, which is based on 32-bit Arm?  Cortex? -M4F core, equipped with rich DSP instructions and hardware floating-point arithmetic units. This MCU has a built-in 256KB Flash memory, supports encryption protection, and is equipped with up to 40KB of SRAM. In addition, it also integrates high-performance analog devices, multiple I/O ports, and rich peripherals. In terms of clock, LKS32MC453 is equipped with a 12MHz high-precision RC clock and a 32kHz low-speed clock, and supports external crystal oscillators ranging from 12MHz to 24MHz. Its internal PLL can provide a maximum frequency of 192MHz.

In the design of the power simulation front-end, the JW3376 AFE device used in the scheme is suitable for 11-16 series of lithium-ion, lithium polymer, and lithium iron phosphate battery packs. Through SPI communication, the host controller can use JW3376 to perform various battery pack management functions, and the chip integrates a 14 bit ADC to sample battery voltage and temperature, while equipped with a 16 bit ADC for charging/discharging current sampling, which can accurately detect battery status.

At the same time, the scheme adopts JW3330 as the driving device. JW3330 is a low-power, 100V high side N-channel MOSFET driving control IC. It disconnects the power supply by cutting off the high-voltage side switch, effectively avoiding problems caused by disconnecting the system grounding wire during low side protection, thereby enhancing the stability and reliability of the BMS system. In addition, JW3330 can work in conjunction with analog front-end chips to achieve separate control of charging and discharging FETs.

In the control part of the charge and discharge switch, the scheme adopts the Xinmai SDN10K018S2C N-MOSFET for pre charging and pre discharging, and the SDN10N3P5B-AA N-MOSFET for charging and discharging control, which can effectively improve the safety of the scheme. In the DC-DC section, the scheme uses Jewate's JWH5140F to step down the voltage of BAT+, resulting in a 5V output from the DC-DC. In the LDO section, the scheme uses Jewate's JW7806 to further step down the output voltage of the DC-DC, resulting in a 3.3V output from the LDO.

In addition, in the design of pressure detection, the solution uses a nano core micro NSPGS2 pressure sensor, which can convert pressure signals from -100kPa to 350kPa into analog/digital output signals with customizable output ranges, helping BMS achieve accurate pressure status monitoring and real-time fault warning.

In addition, the solution is also equipped with products such as Vishay resistors and Molex connectors. With the excellent performance of these products, this solution achieves passive balancing, charge and discharge control, temperature acquisition, high edge protection and other functions, and supports protection mechanisms such as overvoltage/undervoltage protection, high/low temperature protection, circuit breaker protection, overcurrent protection, etc. It can effectively provide comprehensive protection for portable energy storage power sources, ensuring their safe and stable operation.
