An electric bus is a bus that moves using electric motors instead of a traditional gasoline engine. These buses can store electrical energy on the bus itself or receive electricity continuously from an outside source, such as overhead wires. Most electric buses that use stored energy are battery electric buses, which get power from batteries on the bus.
An electric vehicle battery is a battery that can be charged and used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). These batteries are usually lithium-ion batteries designed to provide high power compared to their weight and store a large amount of energy. Compared to liquid fuels, most battery technologies today store less energy for their size.
SAE J1772, also called a J plug or Type 1 connector, follows the international standard IEC 62196 Type 1. It is a North American standard for electrical connectors used in electric vehicles. SAE International manages this standard, which is officially titled “SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler.” SAE sets the rules for the physical design, electrical functions, communication protocols, and performance of the electric vehicle charging system and its connector.
An electric vehicle charging network is a system of charging stations that help recharge electric cars. The term electric vehicle infrastructure (EVI) can mean all charging stations or the network of stations in a country or area. The increase in charging stations can be caused by companies that build them or by government funding.
An electric vehicle battery is a rechargeable battery that powers the electric motors in battery electric vehicles (BEVs) or hybrid electric vehicles (HEVs). These batteries are usually lithium-ion batteries, which are designed to have a high power-to-weight ratio and high energy density. Compared to liquid fuels, most battery technologies today store less energy per unit of weight.
The Tesla Model 3 is an electric-powered mid-size car with a fastback design made by Tesla, Inc. It was introduced in 2017 and is marketed as more affordable than earlier Tesla models. From 2018 to 2020, the Model 3 was the world’s best-selling plug-in electric car before the Tesla Model Y, a crossover SUV built using the Model 3’s frame, took the top spot.
The Tesla Model S is a battery-electric, four-door full-size car made by the American car company Tesla from 2012 to 2026. It was Tesla’s second vehicle and is considered one of the most important electric cars in the industry. It won awards, including the Motor Trend Car of the Year Award in 2013.
Tesla, Inc. (pronounced TEZ-lə or TESS-lə) is an American company that makes cars and clean energy products. The company’s main office is in Austin, Texas.
An electric vehicle (EV) is a vehicle powered mainly by electricity. EVs include road vehicles like cars, buses, trucks, and personal transporters, rail vehicles such as trains, trams, and monorails, boats and submersibles, aircraft like fixed-wing planes and multirotors, and spacecraft. Electric vehicles first appeared in the late 19th century.
Premium efficiency refers to a type of motor efficiency found in certain electric motors that have a rotating shaft. To help reduce energy use, carbon dioxide emissions, and harm to the environment caused by industrial activities, government agencies in many countries have created or are planning laws to support the making and use of electric motors with higher efficiency. This article discusses the development of the premium efficiency standard, known as IE3, and premium efficiency motors (PEMs), along with topics related to the environment, laws, and energy.
