Electrical architectures: vehicle electrical systems, motors, wiring, power distribution and electronic control networks explained.
A fuel cell is a device that converts chemical energy directly into electrical energy, water, and heat through electrochemical reactions. It consists of an anode and a cathode separated by an electrolyte, which is typically a porous membrane. Hydrogen, and air (or oxygen) are fed into the cell. At the anode, the fuel undergoes a…
Hybrid electric vehicles (HEVs) are driven by both an internal combustion engine and one or more electric motors, utilizing energy stored in batteries. Unlike fully electric vehicles and Plug in Hybrids (PHEVs), HEVs cannot be directly plugged in to charge their batteries. Instead, the battery is recharged through regenerative braking and by the internal combustion…
In the ever-evolving landscape of the automotive industry, four interconnected megatrends are reshaping the way we think about vehicles: vehicle electrification, self-driving cars, vehicle connectivity, and shared mobility. As we hurtle into the future, the race to achieve seamless vehicle connectivity and full automation is on, pushing the boundaries of what was once science fiction….
In the ever-evolving landscape of transportation, the need for electrified vehicles has become increasingly apparent. This shift is not just a trend but a critical step towards a sustainable and decarbonized future. In recent years, there has been a growing interest in electrified powertrain systems for both personal and commercial vehicles. These systems encompass the…
Why is car energy management important, especially in hybrid sports cars? The pressing environmental crisis and growing economic consciousness have necessitated a significant reduction in both fuel consumption and emissions from all vehicles. While conventional vehicles with internal combustion engines (ICEs) benefit from the high energy density of hydrocarbon fuels, they grapple with low efficiency….
An AC motor is an electric motor powered by alternating current (AC) that typically comprises two main components. The outer stator contains coils that receive AC to create a rotating magnetic field, while the inner rotor, connected to the output shaft, generates a second rotating magnetic field. The rotor’s magnetic field can be generated by…
A DC motor utilizes direct current (DC) to generate mechanical force, commonly relying on magnetic forces produced by currents in its coils. Nearly all DC motors incorporate an internal mechanism, whether electromechanical or electronic, to periodically alter the direction of current within the motor. DC motors were initially widely adopted as they could be powered…
Introduction Have you ever wondered how cars work? Well, you may know that they have an engine, wheels, and brakes, but have you heard of Drive/X-By-Wire systems? X-by-wire is a term used to describe electronically controlled systems in modern vehicles, which often replace traditional mechanical or hydraulic systems. This technology utilizes electronic controls to manage…
