Switching from fossil fuels to portable power supplies opens up the field for applications on a scale larger than gasoline-powered generators have ever been provided. Using advanced batteries to power everything, using solar panels and small wind turbines to charge batteries, and even using fuel cells to convert hydrogen into electricity for use in the wild could be ways to develop the concept of portable electricity.
We believe advanced portable power technology can meet a variety of challenges, we focus on nine different applications and introduce new green, cleaning and safety solutions.
Emergency power supply
Providing power during outages is the most familiar portable power application for homeowners. Many are powered by internal combustion engines, which run on natural gas and turn on automatically when the grid fails. In fact, they can run as long as they have enough fuel, and are big enough to run refrigerators and freezers, lights and televisions, and even heat pump air conditioning and heating systems. Unfortunately, they produce a lot of greenhouse gas emissions.
Replacing conventional generator systems can be done in several ways. Large batteries, such as the Tesla Powerwall, can be part of home appliance systems. Under normal conditions, the battery is fully charged using power from the grid, and if the power goes out, the battery will power the home without greenhouse gas emissions. (Except for electricity generated by the grid to charge battery systems)
Because internal-combustion systems do not produce toxic emissions, battery power can run indoors and be silent. The downside, however, is that powering large traction devices such as air conditioners or heat pumps requires large and expensive batteries that have a charging life of just a few hours. Charging them from the grid after power is restored is also a long process that takes many hours. It is also possible to charge using solar panels, which add only a few hours to the total operating time of most solar panels, even if the grid remains shut down.
The U.S. military has recognized the deployment of advanced portable power systems as a life-saving strategy. One of the most dangerous tasks soldiers perform in enemy territory is driving convoys to bases and outposts. Bombs and other explosive devices (IEDs) placed on roads can destroy entire tankers, causing serious injury or death to the driver and crew. In addition to using diesel generators to power the base, solar or wind power can be used to power the camp at night or when there is no wind, using excess power stored in the battery system. Renewable energy greatly reduces the number of fuel convoys and improves safety.
Another use for portable power is as a portable power source for soldiers in the field. A modern soldier wears 120 to 200 pounds of equipment. In addition to weapons, ammunition, and body armor, U.S. Army infantrymen are expected to carry up to 25 pounds (11.34 kilograms) of batteries. Battery power can be used to power everything from night-vision gear to radio communications, to smartphones, tablets and new technologies like global positioning systems. Current electricity demand is about 12 watts and is expected to double by 2025.
Lithium-ion batteries, because of their lighter weight and higher energy density, have all but replaced other types of batteries carried by soldiers over the past few decades. Lithium-sulfur dioxide primary batteries, which have a long shelf life and are easy to store, can be used in electronic devices such as GPS and wireless communications. Rechargeable lithium-ion batteries can be used in tactical radios, thermal imagers, electronic radar interference waves (ECM), electronic support measures (ESM) in radar bands, and portable computers.
You can see and hear lithium ion powered portable power sources in the form of tools in any public place. Every portable drill, saw, electric lamp and flat grinder can use rechargeable lithium-ion battery packs, which are often interchangeable between devices made by the same manufacturer.
These power tools are often charged by a gasoline-powered generator, but new options have recently emerged. Ford's F-150 PowerBoost hybrid pickup, for example, has a Pro Power on-board system that provides 2.4 kilowatts or an optional 7.2 kilowatts. There are up to four 120V20A power output ports and a 7.2kW 240V30A power output port in the trunk seat of the pickup. Ford points out that the 7.2-kilowatt Pro Power on-board system can Power metal body workshops including plasma cutters, TiG welders, cutting saws, air compressors, flat grinding machines and work lights.
Heavy-industry diesel-powered tractors used in agriculture and construction are now the target of the electrification of industry giants such as John Deere and Mahindra. Working all day in muddy fields or very rugged areas (six hours on a single charge), electric tractors can carry very large lithium-ion battery packs (150KW/h or more) and can be charged as quickly as possible to ensure use.
Another target for large companies is autonomous electric vehicles. These autonomous electric vehicles will be able to cultivate, sow, fertilize and spray fields without the presence of a driver.
In addition to reducing emissions, electric driving systems are more durable than diesel engines, reducing maintenance costs and downtime due to mechanical failures.
Portable battery devices are also finding their way into the home yard and garden market. Nothing is more annoying than the noise of a gasoline-powered blower. Fortunately, electric blowers have been on the market for more than 10 years and can last 30 to 90 minutes using lithium-ion battery packs. While that's enough for most homeowners, commercial users need batteries that can last longer, and electric blowers are the next step.
Wireless electric lawn mowers initially faced the same limitations as many battery-powered devices, but the advent of lithium-ion batteries has given homeowners a more practical machine. The noise and greenhouse gas emissions advantages of an unlimited electric lawn mower are far greater than those of a gasoline-powered lawn mower.
The humming of the campsite generator is even worse. Rv's and camper trailers can provide comfortable space, but all of this requires power. Without shore power, engines can only be powered by diesel, petrol or natural gas, causing noise and environmental pollution.
Instead, we can use portable power stations. The power station, which is about the size of a microwave oven, is a large rechargeable battery that can be charged with household electricity or connected to a portable solar grid.
The portable power station can provide enough power for small applications in a short period of time without the noise and smoke from the driving generator.
Big events require a lot of power. For example, the 43rd Ryder Cup golf tournament will be held at Whistling Straits Golf Course in Wisconsin on September 24-26, 2021, requiring more than 100 facilities such as power, heating and cooling. These include grandstands, catering, large spectator video screens, operational buildings, the PGA Championship golf shop, the International Pavilion and the opening and closing ceremonies.
In order to meet the power demand, 100 generators were installed to produce a total of 23,000 kilowatts, including a 20 kilowatt Propane Generator that replaced conventional diesel generators at ryder Cup offices, reducing carbon dioxide emissions by 19 metric tons and reducing fuel costs by 30%.
Four 30kW batteries have been prepared for daytime use to minimise engine time, keep noise levels to a minimum for fans to enjoy the game and save an additional 24 tonnes of co2.
The Marine environment
Ships need special power because wet and often salty ocean conditions can wreak havoc on Marine electronics. On a commercial scale, air pollution in ports is a primary environmental concern, such as pollution directly affecting nearby residents. Electrified ships and port machinery have thus received great attention.
Yachts also need a lot of electricity because they are equipped with radios, GPS and other navigation equipment, radars, sounders and a variety of entertainment, air conditioning and heating equipment. Conventional ships' batteries are charged by a generator on a running engine, however, solar panels are installed on top of the deck and cabin to provide charging without producing greenhouse gas emissions. Some sailboats have done away with petrol or diesel engines altogether, instead using electric motors with lithium-ion battery packs, which can be recharged by solar power or by using motors as generators while sailing.
We don't usually think of batteries for medical devices as portable power sources, but everything from hearing AIDS to pacemakers could be portable. A full suite of battery chemicals are used for medical purposes, including ni-Cd, NiMH and Alkaline manganese. Many medical devices run on non-rechargeable primary batteries. For example, zinc-air batteries are commonly used in hearing AIDS. These single-use batteries provide high energy density, are lightweight and relatively cheap to manufacture. These materials are also relatively safe to dispose of in the environment.
Lithium-ion batteries are growing in popularity as the choice for electric vehicles, personal electronics and storage devices for ever-larger power grids. Medtronic is another company that has embraced lithium-ion batteries since 2004, making all of its rechargeable batteries lithium-ion. The company uses an inductive charging system that can be worn on a patient and charged through the skin.
For a long time, the specificity of medical batteries has increased the cost of development and manufacturing. The medical battery market will benefit as efforts are under way to develop ever-improving, more powerful and reliable batteries, especially lithium-ion batteries, for example, for personal electronic devices and electric vehicles.
Handheld navigation devices, such as GPS, make many outdoor types of hiking and biking trips safer. In addition, portable emergency locator beacons and satellite phones can save lives in emergencies. Portable emergency locator beacons and satellite phones have reliable operating capability through lithium-ion battery packs, a result of the development of personal computers and other electronic devices.
The charging system allows you to charge your smartphone, but the pocket-size size makes travel easier.
