Types Of Fast Charging Battery Solutions

Types Of Fast Charging Battery Solutions

Many startups are working on solutions for the energy sector, on a global level. Here are some fast-charging battery methods from some of these promising startups that can prove revolutionary for usage in electric vehicles.

Crux of the Matter

Addionics’s 3D Nanostructure Cathodes
A 3D nanostructure for battery cathodes allows for faster charging and discharging without any loss in energy storage capacity

The 3D Ni nanowire meshes exhibit a semi-ordered structure which has some of the highest combined porosity [measure of the void (i.e. “empty”) spaces in a material] and surface-to-volume ratio among macroporous metals (pores of a size greater than 50 nm.)

GBatteries’ Adaptive Pulse Charing
Used for Li-on and Li-polymer batteries, it determines overcharged, undercharged, normal, and degraded operating conditions, improving the battery life of cells for electric cars.

How Do They Do That?
An AI-based tech uses adaptive pulse charging algorithm for lower impedance periods or less opposition of a circuit to current. Thus, batteries don’t heat up during ultra-fast charging

Geyser Batteries – Aqueous Electrochemistry
Aqueous electrochemistry, wherein the solvent is mostly water, in order to combine the energy storage of batteries with the durability and power of supercapacitors in a single system.

What Are Supercapacitors?
They are electrochemical energy storage devices, which store and release energy by reversible adsorption and desorption of ions at the interfaces between electrode materials and electrolytes.

Invertedpower – DC Fast Charging
This fast charging method converts alternating current (AC) to direct current (DC) for reducing the charging time of a battery. 

How Is This Done?
The tech bypasses the onboard charger of EVs and sends this direct current directly to the battery. So charging is not limited by the performance of the onboard charger and is much quicker.

Your Childhood Dream Of Flying Car, A Reality Soon

Japan-based SkyDrive has completed its first public manned flying car test with their model SD-03. They plan to launch it for public use by 2023. So what’s different about this aerial vehicle? How will it co-exist with traditional road transport?

Crux of the Matter

SkyDrive’s SD-03
The flying demonstration of model SD-03, developed by Japan-based firm Skydrive, took place last month at the Toyota Test Field. This test comes 2 years after SkyDrive was formally launched, and 7 years after the start of the car development under Cartivator, SkyDrive’s founding company, and joint developer.

What’s Special About This?
It is the first public manned flying car test that has been successful and it has already raised around $36.6 million in the Series B round of funding. It could cruise around the test field for 4 minutes with a pilot at a height of 10 ft, who was accompanying the computer-run controls while the on-site staff was monitoring for backup needs.

Designed To Co-Exist With Regular Road Vehicles?
SD-03 is also the world’s smallest electric vertical take-off and landing (eVTOL) vehicle. It has two white lights at its front, and red light underneath, to help onlookers identify the direction that the car is flying in.

What Is eVTOL?
It is an aircraft that can hover, take off, and land vertically. This includes fixed-wing aircrafts, helicopters, cyclogyros/cyclocopters and tiltrotors. It has a flight control augmentation and situational awareness that accompanies vehicles designed for autonomous operation and avoid accidents caused by human error.

Electric operations of eVTOL reduce carbon emissions at the point of operation. As per a paper published last year by the University of Michigan, it was found that a fully loaded flying car would be more efficient than an electric car at a distance of more than 60 miles and gasoline-burning cars for distances greater than 21 miles.

As electrification of aerial mobility will continue to grow in the next decade, they would be greener than even electric road cars, cutting emissions while reducing traffic on busy roads.

What’s SkyDrive’s Main Goal?
Its goal is to bring the flying cars to the market by 2023 and the planned car concept, the SD-XX, will have a capacity of 2 people.

The size of the batteries, air traffic control, and other infrastructure problems will be worked upon till then, to comply with the safety requirements of the Civil Aeronautics Act.
