Electric Cars
An electric car or electric vehicle (EV) is a passenger automobile that is propelled by an electric traction motor, using electrical energy as the primary source of propulsion. The term normally refers to a plug-in electric vehicle, typically a battery electric vehicle (BEV), which only uses energy stored in on-board battery packs, but broadly may also include plug-in hybrid electric vehicle (PHEV), range-extended electric vehicle (REEV) and fuel cell electric vehicle (FCEV), which can convert electric power from other fuels via a generator or a fuel cell. Compared to conventional internal combustion engine (ICE) vehicles, electric cars are quieter, more responsive, have superior energy conversion efficiency and no exhaust emissions, as well as a typically lower overall carbon footprint from manufacturing to end of life (even when a power plant supplying the electricity might add to its emissions). Due to the superior efficiency of electric motors, electric cars ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tesla Model 3
The Tesla Model 3 is a Battery electric vehicle, battery electric powered Mid-size car, mid-size sedan with a fastback body style built by Tesla, Inc., introduced in 2017. The vehicle is marketed as being more affordable to more people than previous models made by Tesla. The Model 3 was the world's top-selling plug-in electric car for three years, from 2018 to 2020, before the Tesla Model Y, a crossover SUV based on the Model 3 chassis, took the top spot.

Fuel Cell
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen fuel, hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most battery (electricity), batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. The first fuel cells were invented by Sir William Robert Grove, William Grove in 1838. The first commercial use of fuel cells came almost a century later following the invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon in 1932. The alkaline fuel cell, also known as the Bacon fuel cell after its inventor, has been used in NASA space programs since the mid-1960s to generate power for sate ...

Charging Station
A charging station, also known as a charge point, chargepoint, or electric vehicle supply equipment (EVSE), is a power supply electrical device, device that supplies electrical power for recharging plug-in electric vehicles (including battery electric vehicles, electric trucks, electric buses, neighborhood electric vehicles, and plug-in hybrid vehicles). There are two main types of EV chargers: Alternating current (AC) charging stations and direct current (DC) charging stations. Electric vehicle batteries can only be charged by direct current electricity, while most mains electricity is delivered from the power grid as alternating current. For this reason, most electric vehicles have a built-in AC-to-DC converter commonly known as the "onboard charger" (OBC). At an AC charging station, AC power from the grid is supplied to this onboard charger, which converts it into DC power to recharge the battery. DC chargers provide higher power charging (which requires much larger AC-to- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
All-electric Range
All-electric range (AER) is the maximum driving range of an electric vehicle using only power from its on-board battery pack to traverse a given driving cycle. In the case of a Battery electric vehicle (BEV), it means the maximum range per recharge, typically between 150 and 400 miles. For a plug-in hybrid electric vehicle (PHEV), it means the maximum range in charge-depleting mode, typically between 20 and 40 miles. PHEVs can travel considerably further in charge-sustaining mode which utilizes both fuel combustion and the on-board battery pack like a conventional hybrid electric vehicle (HEV). Calculating AER is made more complicated in PHEVs because of variations in drivetrain design. A vehicle like the Fisker Karma that uses a serial hybrid design has a clear AER. Similarly a vehicle like the Chevrolet Volt which has a parallel design disengages the internal combustion engine (ICE) from the drivetrain while in electric mode and has a clear AER. However blend-mode PHEVs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery Charger
A battery charger, recharger, or simply charger, is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging after the battery has been fully charged and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle. Other battery types use a timer to cut off when charging should be complete. Other battery types cannot withstand over-charging, becoming damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the stat ...

Power Supply
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, electric current, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power ( ...

Mains Electricity
Mains electricity, utility power, grid power, domestic power, wall power, household current, or, in some parts of Canada, hydro, is a general-purpose Alternating current, alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electrical grid in many parts of the world. People use this electricity to power everyday items (such as domestic appliances, televisions and lamps) by plugging them into a wall outlet. The voltage and utility frequency, frequency of electric power differs between regions. In much of the world, a voltage (nominally) of 230 volts and frequency of 50 Hz is used. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other combinations exist, for example, 230 V at 60 Hz. Travellers' portable appliances may be inoperative or damaged by foreign electrical supplies. Non-interchangeable AC power plugs and sockets, plugs and sock ...

Internal Combustion Engine Cooling
Internal combustion engine cooling uses either air or liquid to remove the waste heat from an internal combustion engine. For small or special purpose engines, cooling using air from the atmosphere makes for a lightweight and relatively simple system. Watercraft can use water directly from the surrounding environment to cool their engines. For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and cost. Higher power engines can move more weight but can also generate more waste heat, meaning they are generally water-cooled. Radial engines allow air to flow around each cylinder directly, giving them an advantage for air cooling over straight engines, flat engines, and V engines. Rotary engines ha ...

Waste Heat
Waste heat is heat that is produced by a machine, or other process that uses energy, as a byproduct of doing work. All such processes give off some waste heat as a fundamental result of the laws of thermodynamics. Waste heat has lower utility (or in thermodynamics lexicon a lower exergy or higher entropy) than the original energy source. Sources of waste heat include all manner of human activities, natural systems, and all organisms, for example, incandescent light bulbs get hot, a refrigerator warms the room air, a building gets hot during peak hours, an internal combustion engine generates high-temperature exhaust gases, and electronic components get warm when in operation. Instead of being "wasted" by release into the ambient environment, sometimes waste heat (or cold) can be used by another process (such as using hot engine coolant to heat a vehicle), or a portion of heat that would otherwise be wasted can be reused in the same process if make-up heat is added to the sys ...

Power Plant
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the electricity generation, generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more Electric generator, generators, rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a Electrical conductor, conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, petroleum, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and use of renewable energy, renewables such as solar power, solar, wind power, wind, geothermal power, geothermal, and hydroelectricity, hydroelectric.

Carbon Footprint
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country Greenhouse gas emissions, adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO2 equivalent, CO2-equivalent) per unit of comparison. Such units can be for example ''tonnes CO2-eq per year'', ''per kilogram of protein for consumption'', ''per kilometer travelled'', ''per piece of clothing'' and so forth. A product's carbon footprint includes the emissions for the entire Life-cycle assessment, life cycle. These run from the production along the supply chain to its final consumption and disposal. Similarly, an organization's carbon footprint includes the direct as well as the indirect emissions that it causes. The Greenhouse gas protocol, Greenhouse Gas Protocol (for carbon accounting of organizations) calls these ''Scope 1, 2 and 3 emissions''. There a ...
