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.

  • Quick Charge is a proprietary technology that allows for the charging of battery-powered devices, primarily mobile phones. Introduced by Qualcomm, it primarily introduced the concept of fast charging to Mobile phones.
  • Qi is an open interface standard that defines wireless power transfer using inductive charging over distances of up to 4 cm, developed by the Wireless Power Consortium. The system uses a charging pad and a compatible device, which is placed on top of the pad, charging via resonant inductive coupling.
  • IEC 61851 is an international standard for electric vehicle conductive charging systems, parts of which are currently still under development. IEC 61851 is one of the International Electrotechnical Commission’s groups of standards for electric road vehicles and electric industrial trucks

This Battery Can Charge Your EV in 5 Minutes

This Battery Can Charge Your EV in 5 Minutes

Thought only mobile phones can be charged in this much time? Well, Israeli company StoreDot has plans of delivering 100 miles of charge to an EV battery in 5 minutes in 2025. Let’s see how this battery works and what it means for EV users in times ahead.

Crux of the Matter

Who Has Made The Tech?
Israeli company StoreDot Ltd. will manufacture this battery, while the lithium-ion samples have been produced by their Chinese strategic partner, Eve Energy Co.

Where Was It Demonstrated?
Earlier demonstrated in their drones and phones, this time a two-wheeled scooter used their battery. It is slated for a 2025 mass rollout, as per CEO Doron Myersdorf.

How Far Can The EV Travel Then?
With the available charging infrastructure, 100 miles of charge can be provided to an EV by charging the battery for 5 minutes.

Saves Users From Range Anxiety
If the experience of charging an EV is similar to fuelling a petrol/diesel car, the anxiety of ‘running out of charge in the middle of nowhere or sitting in the charging station for a long time’ goes away.

Isn’t This Possible With Existing Batteries?
Well, existing Li-ion batteries use graphite as an electrode, into which the lithium ions are pushed for storing charge. But on being rapidly charged, the ions can get congested, converts into metal and then short circuits the battery.

Then What Does StoreDot Battery Use?
It replaces graphite with semiconductor nanoparticles, into which ions can pass more quickly. These particles are currently based on Germanium, which is easier to handle but would be based on silicon later, which is cheaper.

I think technologies [like StoreDot’s] could start entering the market. But, since they will be more difficult to manufacture, we’re likely to initially only see them in niche markets that are highly performance-driven and not as price-sensitive.

Bengaluru-based Pravaig Dynamics has conceptualised its first indigenous electric car that claims to run 504 km on a single charge like Tesla’s cars. Read about it in detail: Pravaig MK-1: The Longest Range EV In India

  • Giga Nevada or Gigafactory 1 is a lithium-ion battery and electric vehicle component factory in Storey County, Nevada. The facility is owned and operated by Tesla, Inc., and supplies the battery packs for the company’s electric vehicles.
  • Akira Yoshino is a Japanese chemist who created the first safe, production-viable lithium-ion battery. Yoshino was awarded the Nobel Prize in Chemistry in 2019.
  • The jelly roll or Swiss roll design is the design used in the majority of cylindrical rechargeable batteries. The design gets its name because the cross-section of the battery looks like a Swiss roll cake. Occasionally the design is also used for primary (non-rechargeable) batteries
