A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures.

Ultium vehicles are powered by a modular family of five drive units and three electric traction motors, known collectively as "Ultium Drive". [5] Mass production of Ultium Drive motors and units is scheduled to start in 2024 at the GM Toledo [12] [13] and St. Catharines propulsion factories.
These vehicles are propelled by at least one electric motor. [1] [2] Good example is an electric locomotive that is drawing power directly from overhead wire or third rail.. "Electric vehicle" is often cleverly interchanged with "Electrified vehicle" [3] which doesn't specify what kind of powertrain vehicle actually h
A full charge reportedly takes 10-12 hours from a standard North American 120 V, 15 A household outlet, or 4 hours from a 240 V 15 A SAE J1772 electrical vehicle supply. [ citation needed ] The lithium-ion battery in the initial Voltec production vehicle is kept in a state-of-charge (SOC) range of between 30% and 80%, with the on-board ...
Automotive engineering, along with aerospace engineering and naval architecture, is a branch of vehicle engineering, incorporating elements of mechanical, electrical, electronic, software, and safety engineering as applied to the design, manufacture and operation of motorcycles, automobiles, and trucks and their respective engineering subsystems.
Engine controls demand one of the highest real-time deadlines, as the engine itself is a very fast and complex part of the automobile. Of all the electronics in any car, the computing power of the engine control unit is the highest, typically a 32-bit processor. [citation needed] A modern car may have up to 100 ECU's and a commercial vehicle up ...
A parking area with an overhead electrical net was in use at Seoul Grand Park Zoo in South Korea, to recharge electric vehicles [citation needed], This was similar to a fairground bumper car arrangement which allowed vehicle batteries to be recharged, prior to introduction of the more modern OLEV Online Electric Vehicle system.
Motor vehicle type approval is the method by which motor vehicles, vehicle trailers and systems, components and separate technical units intended for such vehicles achieve type approval in the European Union (EU) or in other UN-ECE member states. There is no EU approval body: authorized approval bodies of member states are responsible for type ...
