STMicroelectronics Chipset May Extend Li-Ion Auto Battery Life

STMicroelectronics says that it has developed a new automotive battery pack for hybrid electric and electric vehicles. The company says that it has improved battery management via a new chipset, and has combined this technology with Li-ion cells from LG Chem. STMicrolectronics says that the new combination will provide better fuel economy and lower carbon emissions than that available in vehicles that use lower-voltage nickel-metal-hydride batteries.

The chipset manages the charge and discharge cycle of lithium-ion cells in automotive applications, extending the lifetime of the cell and adding another level of safety. Each chip handles up to ten battery cells and permits communication between itself and up to 31 other STMicroelectronics management chips in the same system. The combined system can manage up to 1,600 volts to electric motors used in HEVs and EVs.

The ST chip combines the management of digital logic, analog circuitry and power transistors to provide extremely precise control in a single package

The company says its automotive development is focused on products that will reduce the consumption of fossil fuels and the production of carbon emissions. The new, low-cost chip will enable other automotive- and transportation-related Li-ion applications, including electric bicycles, scooters and trucks.
