Ultium is characterized by a modular layout, using an Ultium battery to supply power to one or two Ultium Drive unit(s) using a common set of power electronics (charging, battery management system, and inverter). The high-voltage battery is composed of pouch cells that can be stacked horizontally or vertically, depending on the form factor ...
Torque vectoring is a technology employed in automobile differentials that has the ability to vary the torque to each half-shaft with an electronic system; or in rail vehicles which achieve the same using individually motored wheels. This method of power transfer has recently [when?] become popular in all-wheel drive vehicles. [1]
Driver Information Center in a 2013 Chevrolet Cruze showing TPMS readout. A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light.
1900 Lohner-Porsche "Chaise" battery electric vehicle with two front-wheel hub motors [7] 1900 Lohner–Porsche "Mixte" racecar with four wheel-hub motors [7] Several electric, combustion, and steam powered in-wheel motor designs were patented in the 1880s and 1890s. [8]
The SH-AWD all-wheel-drive system was lauded by Popular Science as one of the best automotive innovations of 2004, [citation needed] and as part of an already tech-filled vehicle helped to earn the 2005 "Tech car of the year" from CNET. [3] Honda has since announced an evolution of SH-AWD using hybrid electric technology.
The manufacturing of powertrain components and systems is important to industry, including the automotive and other vehicle sectors. Competitiveness drives companies to engineer and produce powertrain systems that over time are more economical to manufacture, higher in product quality and reliability, higher in performance, more fuel efficient, less polluting, and longer in life expectancy.
The use of separate motors for the front and rear drive wheels eliminates the need of a drive shaft that is ubiquitous in four-wheel drive ICE vehicles, freeing up space for bigger battery modules, which are commonly mounted on the chassis floor between the axles. [1]
The development of the IMA system is a result of optimizing the various technologies that Honda has built over the years, including the lean-burn combustion, low-emission engines, variable valve timing, high-efficiency electric motors, regenerative braking, nickel-metal hydride (Ni-MH) battery technology and the microprocessor control.
