NXP introduces advanced battery cell controllers to improve battery management systems for electric vehicles.

Posted on

NXP Semiconductors has released its new BMx7318/7518 family of 18-channel battery cell controllers. These integrated circuits are designed to improve battery management system (BMS) performance and safety in electric vehicles, industrial energy storage, and 48 V battery systems. The family uses advanced architecture with dedicated analog-to-digital converters (ADCs) for each channel. This offers flexibility, allows for easy replacement of components, and provides a streamlined, cost-effective solution. It meets Automotive Safety Integrity Level C (ASIL-C) and industrial Safety Integrity Level 2 (SIL-2) safety standards.

The BMx7318/7518 series includes built-in analog front-end functions, battery junction box features, and gateway capabilities, like current sensing and a way to connect to other devices. NXP says this integration reduces the need for external components by 50%, which lowers costs for manufacturers and suppliers. The design is resistant to electromagnetic interference and can handle high currents in semi-centralized BMS setups.

The new design focuses on separate channels to avoid interference and improve measurement accuracy. It supports balancing across all channels up to 150 mA at temperatures up to 125°C, with single-channel capability up to 300 mA, which significantly improves battery balancing efficiency. It also has a very low power mode that uses only 5 µA, making it suitable for long storage or transportation. Additionally, it includes a dedicated hardware alarm pin for quickly detecting overcurrent issues.

“The BMx7318/7518 IC family represents another step forward in battery management innovation,” said Naomi Smit, Vice President and General Manager at NXP Semiconductors. “By integrating advanced ADC architecture, high-current balancing, and strong resistance to interference, we help our customers create more efficient and scalable energy systems. This solution simplifies system design and meets safety requirements for both automotive and industrial uses. We are excited to support the growing need for sustainable energy with technology that delivers performance, flexibility, and reliability.”

The BMx7318/7518 family is expected to be available in November 2025.

I'm Rohan Mehta, the voice behind KhelRe—a trusted and steadily growing blog dedicated to electric vehicles (EVs) in India. With over five years of experience as a tech and automotive blogger, I turned my frustrations with owning an EV into a mission: to help others make more intelligent choices in this fast-evolving world of electric mobility. I've been an early adopter of EV technology—I repurchased my first electric scooter in 2019. That experience opened my eyes to both the promises and the pitfalls of this new mode of transport. From slow charging times and range anxiety to misleading specs and hidden costs, I've faced it all. But instead of walking away, I decided to write about it. That's how KhelRe was born—a no-nonsense, hands-on blog where I share practical, real-world reviews of EV cars, bikes, and scooters. I break down features, range, performance, and pricing from a user-first perspective. I take pride in simplifying complex tech into clear, valuable insights—offering tips, ownership stories, and advice you won't find in flashy press releases or sales brochures. Whether you're a first-time EV buyer or just a curious auto enthusiast, my goal is to help you navigate the EV landscape with confidence. My motto: "EV knowledge should come from experience, not just brochures." When I'm not test-driving the latest e-scooter or comparing charging networks, you'll probably find me tinkering with my garage EV setup, chatting with fellow enthusiasts online, or sipping chai while writing my next blog post from a cosy local café.
