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
