July 25, 2024. By Aishwarya

Our extensive range of sensor technologies collects vital information on battery health, motor performance, and environmental conditions, essentially serving as the eyes and ears of EVs, discloses Praveen Jose, Technical Lead, FAE, Analog Devices in his latest chat with Aishwarya Saxena, Energetica India.

Que: Can you elaborate on Analog Devices' role in the Intelligent Edge ecosystem in India and how does Analog Devices contribute to the development of sustainable transportation solutions?

Ans: Two sectors that are critical to India's future are the development of sustainable mobility solutions and the Intelligent Edge ecosystem, both areas where Analog Devices (ADI) stands out as a major player. ADI specializes in enabling data processing and gathering within electric vehicles (EVs) at the edge. The key to ADI's prowess lies in sensor fusion.

Our extensive range of sensor technologies collects vital information on battery health, motor performance, and environmental conditions, essentially serving as the eyes and ears of EVs. Our high-performance processors and controllers analyze this data in real-time, enabling on-board decision-making that enhances safety features, optimizes power management, and even lays the foundation for predictive maintenance. Furthermore, by connecting EVs to other systems, ADI's connectivity solutions facilitate data transfer and remote monitoring for further optimization.

Sustainability is one of ADI's other main priorities. Our Battery Management Systems (BMS) are essential for maximizing battery longevity and performance, which lowers battery waste and increases the efficiency and range of electric vehicles.

In addition, our proficiency in power electronics results in effective power converters and inverters, reducing energy loss inside the electric vehicle's powertrain and promoting a more environmentally friendly outcome. With an eye toward the future, ADI actively investigates developments in battery technology, creating solutions that work with the sustainable battery chemistries of the next generation.


Que: How does ADI integrate advanced software algorithms with real-time data analysis for battery management?

Ans: ADI's Battery Management Systems (BMS) integrate advanced software algorithms with real-time data analysis for optimal battery management in EVs. Sensors gather critical data on cell voltage, current and temperature, which is then analyzed by the algorithms to estimate battery health (SOH), remaining capacity (SOC) and enable cell balancing for uniform usage.

Additionally, these algorithms can trigger safety features and potentially predict future issues, all contributing to maximized range, extended lifespan and enhanced safety for electric vehicles.


Que: What measures does ADI take to reduce costs associated with battery management and how is ADI empowering the EV ecosystem in India?

Ans: ADI tackles cost in battery management with flexible design options (wired/wireless BMS) and performance optimization for extended battery life, lowering long-term replacement costs. Our wireless solutions streamline production for potential cost reduction, particularly in high-volume manufacturing.

ADI empower India's EV ecosystem by developing tailored BMS solutions, upskilling the workforce through training programs, fostering future innovation through collaboration and ensuring a cost-effective and reliable supply chain via their global network.

Analog Devices (ADI) has recently expanded its Battery Management System (BMS) portfolio, introducing a new chipset that boasts the highest level of integration seen in the market to date. This advancement not only enhances performance but also simplifies the complexity of customer systems. It ensures improved battery utilization and elevates safety standards, marking a significant step forward in battery management technology.


Que: Can you provide insights into ADI's active involvement in R&D in India and what are some of the key challenges ADI faces in the EV space, and how are they addressed?

Ans: ADI’s Bengaluru research facility is one of the top design facilities globally, with significant investment made for Indian R&D talent and innovation. Since the Indian market prioritizes affordability, ADI addresses this localization and partnerships with local suppliers to reduce costs and develop high-performance yet cost-optimized technologies. Another challenge that exists within the Indian market is the need and lack for a skilled workforce. To address this, ADI collaborated with academic institutions and provided internal training programs to constantly upskill employees with necessary tech skills.

ADI also provides industrial training to universities to enhance awareness of the latest industrial technologies required for the current market. This initiative bridges the gap between academic knowledge and practical industry requirements, equipping students with the skills necessary to excel in today's industrial market. By collaborating with universities, ADI ensures that the future workforce is well-versed in cutting-edge technologies and industry practices, fostering innovation and driving economic growth.


Que: Can you explain the role of ADI's radio frequency (RF) technology in the EV ecosystem and how does ADI's digital and sensor technologies support the development of intelligent transportation?

Ans: ADI’s Radio Frequency technology plays a crucial role in the EV ecosystem where the RF is used for wireless communication between EVs and charging stations, leading to an easier charging process. Radio Frequency technology also contributes to vehicle-to-everything (V2X) communication, thereby improving safety and traffic management through car-to-car and car-to-infrastructure communication.

ADI’s digital and sensor technologies are the building force for the development of intelligent transportation. This not only powers the ADAS in EVs, using sensors like radar, LiDAR, and camera to enable functions like lane departure warning and automatic emergency braking. This not only supports the collection and processing of data but also contributes to an advanced in-car experience through gesture and voice control integration.


Que: Any upcoming future developments or launches, we can expect from ADI in the realm of electric mobility this year?

Ans: Automotive Ethernet connectivity (E2BTM) has paved the way for next-generation zonal architecture. It eliminates gateways and simplifies the wiring harness by connecting edge sensors and actuators based on location rather than function. This reduces vehicle weight, aiding in better fuel efficiency.

Analog Devices’ innovations for the automotive cabin enable a more immersive, personalized, and safer mobility experience. Our solutions leverage power management ICs, high-performance DSPs, a broad portfolio for automotive connectivity and networking, audio and video converters, sensing, and application-specific software and development tools. This suite of offerings enables large, high-definition displays, advanced audio and acoustic capabilities, driving safety systems, and more.
