jump start manufacturers : LG Chem and ST Improve Hybrid Electric Vehicle Battery Technology
Semiconductor supplier STMicroelectronics (ST), together with South Korea’s largest chemical company LG Chem, has unveiled details of a new car battery technology that can both reduce gasoline consumption and reduce carbon dioxide emissions. It can significantly increase the market potential of electric and hybrid electric vehicles (HEVs). The new battery pack combines LG Chem’s lithium battery technology with ST’s advanced battery management chip.
Hybrid electric vehicles use two types of power: a conventional gasoline internal combustion engine and a motor powered by a rechargeable battery pack. Hybrid electric vehicles have gradually become an important segment of the automotive market due to higher fuel efficiency and lower air pollution. Current hybrid electric vehicles generally use NiMH technology. The advantage of this technology is that the control circuit is relatively simple, but the battery itself is heavy and the operating voltage is low.
Lithium batteries are widely used in portable consumer electronics. Compared with nickel-metal hydride batteries, lithium batteries have more than twice the energy-to-weight ratio of nickel-metal hydride batteries. The self-discharge of lithium batteries is also small when not in use. However, lithium batteries currently have certain limitations in high-power applications, because the charge and discharge cycles of lithium batteries must be carefully managed to avoid improper use of the battery. Therefore, in order to become a power source for high-power applications, lithium batteries must integrate sophisticated and highly reliable battery management circuits.
To control the charge/discharge cycle, LG Chem’s new lithium battery pack uses ST’s advanced battery management chip. ST’s battery management chip ensures high reliability and long-term reliability while maintaining economics, even in demanding automotive powertrain systems. .
ST’s battery management chip uses its unique BCD (Bipolar-CMOS-DMOS) manufacturing technology, which integrates digital logic, high-precision analog measurement circuitry and power processing transistors. Battery-based management systems based on STMicroelectronics accurately and reliably control battery charging and discharging cycles, ensuring safe battery operation and extending battery life. Each chip can manage up to ten lithium battery cells, and the chip also provides a communication interface for the STMicroelectronics power management chips in the system to communicate with each other. With this communication function, designers can connect up to 32 battery management chips in series to manage motor battery packs with output voltages up to 1,600V.
BCD, commonly referred to as smart power, is a semiconductor manufacturing technology. STMicroelectronics uses this technology to fabricate three basic components of a circuit on a low-cost single-chip: digital logic for high-speed computing, analog circuitry for high-precision measurement and control, and power transistors for high-current processing. STMicroelectronics is a pioneer in BCD technology and has been the market leader. Its smart power products are fully mass-produced and are widely used in a variety of products, from printers and fax machines to hard drives to management window lifts. STMicroelectronics’ smart power products can be seen in the controllers that move with the mirrors.
LG Chem / STMicroelectronics solutions can reduce battery cost and weight, improve the reliability of lithium battery packs, and enable lithium batteries to be used in a variety of new applications from electric motorcycles to electric bicycles to heavy trucks.
