Examining battery management solutions in new eBook

Mouser has published a new eBook in collaboration with Vishay Intertechnology, Inc., analysing the considerations and challenges of designing high-performing and reliable battery systems.

The eBook, '8 Industry Experts Discuss Battery Management Solutions', focuses on the battery management system (BMS), the electronic control circuit that monitors and regulates the charging and discharging of batteries. The BMS informs the systems of the battery's state of charge (SOC), ensures that the conditions are optimal for the battery's state of health (SOH), and protects the battery from fault conditions that could damage it. The eBook examines proper BMS design and how Vishay helps its customers attain the best performance and reliability for battery systems. The eBook also incorporates examples from Vishay's wide portfolio of discrete semiconductors and passive components to help lengthen battery life, enhance operational safety, and provide reliable data acquisition for precise battery health monitoring and efficient power management.

The Vishay VOA300 linear optocoupler is ideal for voltage and current monitoring in the BMS of EV/HV. The automotive-qualified device delivers a fast response, gain stability, and improved isolation voltage over other standard optocouplers.

The WSBE series Power Metal Strip shunt resistors feature a very low resistance and a high power capability, enabling high current sensing to 1825A. These resistors use a proprietary processing technique that reduces the TCR to <10ppm/C across the operating range of -55C to 150C. The devices also provide many other advantageous attributes that help simplify BMS designs and lower costs while achieving the highest levels of performance.

The company's surface-mount PAR TVS diodes protect sensitive electronics against voltage transients induced by inductive load switching and lightning on ICs, MOSFET, and signal lines of sensor units for automotive.

Comprising two resistors integrated into one surface mount moulded package, the CDMM thick film chip dividers supply a single-component replacement for multiple discrete resistors in high voltage up to 1.5KV divider applications. The space-saving AEC-Q200 qualified device is optimised for electric automobiles' high-power DC-DC converters and inverters.

The Vishay/Siliconix SQ automotive power MOSFETs are AEC-Q101 qualified and produced using a special process design optimised for the automotive industry. These devices are available in various package options for design flexibility.
