NXP Semiconductors has introduced a new generation of battery cell controllers. The components from the BMx7318/7518 family measure the cell voltage of up to 18 serially connected lithium-ion cells. Applications include high-voltage batteries in electric vehicles, industrial energy storage systems, and 48-volt onboard networks.

Technically, the ICs are based on an architecture with a separate analog-to-digital converter (ADC) per channel. This separation minimizes the so-called crosstalk between channels, thus improving the accuracy of the measurements. At the same time, the new series enables a simplified design that requires up to 50 percent fewer external components.

Flexible Cell Topologies And High Current Capability

Another feature is the extended cell balancing management. Up to 150 mA can be balanced per channel, and under certain conditions up to 300 mA. This shortens charging time and enables faster balancing within large battery packs. The system is complemented by a hardware interrupt for quick response during overcurrent events.

The ICs are qualified for both automotive applications (ASIL-C) and industrial systems (SIL2), and they support semi-centralized BMS architectures. The standby current has also been optimized: with only 5 µA in sleep mode, the chips are suitable for long-term storage and transport. The BMx7318/7518 family is scheduled for series availability starting in November 2025. (sb)
