【News Summary】The new BMx7318/7518 series IC (integrated circuit) products offer advanced, cost-effective 18-channel lithium-ion battery cell control solutions, specifically designed to enhance the performance and safety of electric vehicles, energy storage systems, and 48V applications.

5 July 2025 — NXP Semiconductors N.V. (Nasdaq: NXPI) has recently launched its new 18-channel lithium-ion battery cell controller IC product series, the BMx7318/7518, specifically designed for high-voltage battery management systems (HVBMS) in electric vehicles, industrial energy storage systems (ESS), and 48V battery management systems. The series is based on NXP's advanced per-channel independent analogue-to-digital converter (ADC) architecture, offering flexible model options and cross-model pin compatibility, providing customers with cost-effective solutions while improving overall battery management system performance. The new IC product series also meets automotive ASIL-C and industrial SIL-2 functional safety certifications.

【Significance】  

As global demand for scalable, cost-effective energy solutions grows, battery management systems must balance precision, lifespan, reliability, and flexibility.  

The NXP BMx7318/7518 IC series adopts a new chip architecture, combining leading-edge high-current injection method (BCI) and electromagnetic interference (EMI) performance to reduce external component requirements by 50%, helping OEMs and Tier 1 suppliers significantly reduce costs.

Additionally, the solution integrates an analogue front end, battery junction box, and gateway functionality into a single chip (such as I-sense or SPI2TPL bridge). Furthermore, they support a semi-centralised BMS architecture, ensuring BMS stability while optimising system-level costs.

Zhu Yuping, Director of Electrification Market, Greater China, NXP Semiconductors, said: "The BMx7318/7518 is an important new addition to NXP's electrification system solutions portfolio. Its ultra-long lifespan, system flexibility, and reliability throughout the lifecycle perfectly align with the diverse needs of the automotive electrification and industrial energy storage markets. Notably, this product series was developed by the NXP team based on Chinese customer needs, efficiently responding at Chinese speed, and completed in China in terms of definition, design, and development. Its outstanding overall performance has also gained the favour of global customers. As a company with abundant technical expertise, NXP is committed to creating more competitive products for global customers through cost advantages and efficient innovation models."

Naomi Smit, Vice President and General Manager of the New Energy and Drive Systems Product Line at NXP Semiconductors, stated, "The BMx7318/7518 IC series marks another innovative breakthrough in battery management technology. By integrating advanced ADC architecture, high-current balancing functionality, and robust electromagnetic interference resistance, we enable customers to design more efficient and scalable energy systems. This solution not only reduces system complexity but also meets the safety standards required for automotive and industrial applications. We are proud to continue meeting our customers' needs for sustainable energy with technology that combines high performance, flexibility, and reliability."

【More Details】

The BMx7318/7518 adopts a new integrated circuit design, achieving fully independent cell sampling channels to avoid crosstalk and improve filtering accuracy. This design supports flexible layouts with up to 18 busbars and features full-channel parallel 150mA balancing capability (supporting 125°C high temperatures), with a maximum of 300mA per channel, significantly improving battery balancing efficiency.

Additionally, the system includes an ultra-low power mode (only 5μA) to meet long-term storage and deep-sea transportation requirements, and uses dedicated hardware alarm pins for rapid response to overcurrent events.

【Availability】  

The BMx7318/7518 series is expected to be available starting November 2025. For more information, please visit the product website (https://www.nxp.com.cn/products/BMA7318-BMI7318-BMA7518).
