Electric cars in the context of Passenger car

A lithium-ion battery, or Li-ion battery, is a type of rechargeable battery that uses the reversible intercalation of Li ions into electronically conducting solids to store energy. Li-ion batteries are characterized by higher specific energy, energy density, and energy efficiency and a longer cycle life and calendar life than other types of rechargeable batteries. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introduction in 1991; over the following 30 years, their volumetric energy density increased threefold while their cost dropped tenfold. In late 2024 global demand passed 1 terawatt-hour per year, while production capacity was more than twice that.

The invention and commercialization of Li-ion batteries has had a large impact on technology, as recognized by the 2019 Nobel Prize in Chemistry.Li-ion batteries have enabled portable consumer electronics, laptop computers, cellular phones, and electric cars. Li-ion batteries also see significant use for grid-scale energy storage as well as military and aerospace applications.

Automotive electronics are electronic systems used in vehicles, including engine management, ignition, radio, carputers, telematics, in-car entertainment systems, and others. Ignition, engine and transmission electronics are also found in trucks, motorcycles, off-road vehicles, and other internal combustion powered machinery such as forklifts, tractors and excavators. Related elements for control of relevant electrical systems are also found on hybrid vehicles and electric cars.

Electronic systems have become an increasingly large component of the cost of an automobile, from only around 1% of its value in 1950 to around 30% in 2010. Modern electric cars rely on power electronics for the main propulsion motor control, as well as managing the battery system. Future autonomous cars will rely on powerful computer systems, an array of sensors, networking, and satellite navigation, all of which will require electronics.

Formula E, officially the ABB FIA Formula E World Championship for sponsorship reasons, is the highest class open-wheel single-seater motorsport championship for electric cars. The inaugural championship race was held in Beijing in September 2014. Since 2020, the series has had FIA world championship status.

The ABB FIA Formula E World Championship season consists of a series of races, each known as an ePrix (written as "E-Prix" on the official website). These take place in multiple countries and continents around the world, mostly on street circuits created specifically for Formula E on closed public roads in the centre of major cities, with a small number on purpose-built circuits such as Autódromo Hermanos Rodríguez in Mexico City. A points system is used at each ePrix to determine two annual World Championships: one for the drivers, and one for the teams. Each driver must hold a valid e-Licence issued by the FIA to compete.
