TI And Delta Collaborating On EV On-board Charging

21 June 2024

Dallas-based Texas Instruments Inc (TI) has announced a long-term collaboration with global power and energy management manufacturer Delta Electronics to create next-generation electric vehicle (EV) on-board charging and power solutions. This will leverage both companies’ R&D capabilities in power management and power delivery in a joint innovation laboratory in Pingzhen, Taiwan. Together, TI and Delta aim to optimize power density, performance and size to accelerate the realization of safer, faster-charging and more affordable EVs.

“The transition to electric vehicles is key to helping achieve a more sustainable future, and through years of collaboration with Delta Electronics, we have a solid foundation to build upon,” says Amichai Ron, senior VP for Embedded Processing at TI. “Together with Delta, we will use TI semiconductors to develop EV power systems like on-board chargers and DC/DC converters that are smaller, more efficient and more reliable, increasing vehicle driving range and encouraging more widespread adoption of electric vehicles,” he adds.

“Delta has been developing high-efficiency automotive power products, systems and solutions since 2008 to help reduce transportation-related carbon emissions,” says James Tang, executive VP of Mobility and head of the Electric Vehicle Solutions business group at Delta. “Through the establishment of this joint innovation laboratory with TI, Delta intends to leverage TI’s abundant experience and advanced technology in digital control and GaN [gallium nitride] to enhance the power density and performance of our EV power systems. With more leading-edge product development and design capabilities, we aim to achieve closer technology exchange and collaboration to accelerate product development and improve product safety and quality.”

The firms cite three phases of development for next-generation automotive power solutions

Phase one for the collaboration focuses on Delta’s development of a lighter-weight, cost-effective 11kW on-board charger, using TI’s latest C2000 real-time microcontrollers (MCUs) and TI’s proprietary active electromagnetic interference (EMI) filter products. The companies are working together using TI’s products to reduce the charger’s size by 30% while achieving up to 95% power conversion efficiency.
In phase two, TI and Delta will leverage the latest C2000 real-time MCUs for automotive applications to enable auto-makers to achieve automotive safety integrity levels (ASILs) up to ASIL D, which represents the strictest automotive safety requirements. Highly integrated automotive isolated gate drivers will further enhance the power density of on-board chargers, while also minimizing overall solution size.
In phase three, the two companies will collaborate to develop the next generation of automotive power solutions, capitalizing on TI’s more than 10 years of experience in developing and manufacturing products with GaN technology.

“The rapid growth of electronics in automotive applications has enabled more feature-rich, efficient and safer vehicles. However, technical challenges remain,” notes Luke Lee, president of Taiwan, Japan, Korea and South Asia at TI. “Having been in Taiwan for 55 years, coupled with decades of experience in automotive power management, TI has built a strong connection with the local automotive industry. Establishing this collaboration and joint innovation laboratory with Delta is just one more way TI is driving vehicle electrification forward.”
