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.

Can An EV Recharge From 0 To Full In 10 Minutes?

Can An EV Recharge From 0 To Full In 10 Minutes?

Apparently, yes. Toyota is soon going to roll out a revolutionary solid-state battery, that will allow Electric vehicles (EV) to recharge in just 10 minutes! Till the prototype is officially released in 2021, let’s see how it can be a gamechanger beyond its usage in EVs.

Crux of the Matter

What Else Does Toyota Claim?
How its newly developed batteries can enable a maximum EV range of 500km in 1 full charge, “all with minimal safety concerns.” This is a great push in the booming EV industry. 

Where Are SSBs Used?
Solid-state batteries have found use in pacemakers, RFID (Radio-frequency identification) and wearable devices, since they are safer, with higher energy densities, at higher costs though.

What Is An Electrolyte?
A battery’s electrolyte is a conductive chemical mixture, which allows the flow of current between the anode and cathode.

Lithium Ion VS Solid State
Apart from Lithium-ion battery using a liquid electrolyte like  lithium salt in an organic solvent, they have lesser energy density than SSBs. Reason: Instead of requiring large separators between the liquid cells, SSBs require very thin barriers to prevent a short circuit.

Moreover, SSBs are less reactive than today’s liquid or gel, so they are long lasting and won’t explode or catch fire if they are damaged, meaning safer products for consumers. Like Samsung was forced to recall Galaxy Note 7 handsets following lithium-ion fires.

A Simple Solution To Complex EVs: Gogoro

A Simple Solution To Complex EVs: Gogoro

The Taiwanese smart-scooter company Gogoro is planning to expand its base worldwide, with its brilliantly thought battery swapping infrastructure. So how will this help the EVs make a more solid mark in the petroleum-dominated industry? Let’s find out.

Crux of the Matter

What Is Gogoro?

  • It is an innovative company which develops and sells electric scooters and maintains a battery swapping infrastructure.
  • Founded in 2011, by Horace Luke & Matt Taylor.
  • Smart-scooters released: Gogoro 1, Gogoro 2, Eeyo 1 and 1S
  • Initial Target: Taiwan, a country with the highest density of scooters in the world.

Wait.. Battery Swapping Infrastructure?
The Gogoro Energy Network is a battery swapping infrastructure, modularly designed to be implemented in urban regions. They recently opened larger battery swap stations with 50% more capacity, in order to meet the surging demand. Riders of smart-scooters would be able to swap out depleted batteries at a network of GoStation kiosks, for a monthly subscription fee.

Why Is It Needed?
Like in the case of other Electric Vehicles, there has always been a logistical issue of batteries taking a long time to charge than their rival gas-driven cars. This will be solved with these battery ‘vending’ machines providing instant replacements.

Moreover, Gogoro smart-scooters/e-bikes can charge at owner’s homes along with the energy network set up at metro branches, pharmacy, and corner stores to offer 24×7 battery swap service.

So What’s Great About These E-bikes?
The latest Gogoro Eeyo 1 & 1s is equipped with:

  • Smartwheel all-in-one motor: hides the motor, battery & controller in the hub of the rear wheel, giving it a clean look
  • Carbon fiber diamond frame: to carry easily over the shoulder
  • Sports & Eco Mode with speeds of 64km to 89 km respectively, with a 123Wh battery.
  • Gogoro App to start and stop the bike, with a cloud-based service that analyses the battery status and tells you about the nearest charging station to replenish it.


Aiming For A Smart Urban Transportation?
Gogoro has taken a big step towards a standardized EV future with its battery ‘swapability’ and charging setups. Their GoStations’ small size means that they are easily deployable, wherein a single 15 amp station runs on an energy of a big refrigerator. Till now 1200 battery swap stations have been installed in Taipei, Taiwan.

Next they are targeting an average distance of 1.3 km between each station and the battery changing time of 6 seconds at most. Since it’s reception, they have shipped 35,000 scooters and raised over $300 million for these greener and more sustainable vehicles.

History of Electric Vehicles

History of Electric Vehicles

Electric vehicles have been in existence longer than the General Motors EV1 of the late 1990s and today’s Tesla Inc. Let’s understand how things came to be as they are now.

Crux of the Matter

1830s – 1840s
1832-1839 – Batteries (galvanic cell or voltaic cell) were not yet rechargeable. Scotland’s Robert Anderson built the first motorized carriage between this period.

Then Robert Davidson of Aberdeen, built a prototype electric locomotive (rail transport vehicle) in 1837. William H. Taylor in the US made similar motors from 1838.Both these men worked independently, unknown to each others’ works.

1841
Davidson’s advanced version called Galvani was launched. It could go 1.5 miles at 4 mph towing 6 tons of heavy goods. The railway workers saw this as a threat to their jobs tending steam engines and so they destroyed it.

1859
Rechargeable batteries came into existence, with the invention of the lead–acid battery by French physicist Gaston Planté.

1884
Thomas Parker helped in the deployment of electric-powered trams (a rail vehicle that runs on tracks in public streets) and subsequently built prototype electric cars in England.

1890
Scottish chemist, William Morrison, applied for a patent on the electric carriage he’d built and then it appeared in a city parade in 1888. It had 24 battery cells that needed recharging every 50 miles, with front-wheel drive, 4 horsepower & a top speed of 20 mph. Later on, it gathered interest in the 1893 Chicago World’s Fair.

1900s
Electric battery cars became popular for taxi services during this period, after Walter Bersey had introduced them in London. There was General Motors’ EV1 launched in 1996 and in 1997, the first mass-produced gas-electric hybrid vehicle Toyota Prius was launched in Japan.This was followed by the Honda Insight in 1999 US, Japan and thereafter Europe, North America and worldwide in 2000.

However, in the early 1900s, battery-powered vehicles had an edge over their gas counterparts. They did produce a high level of noise, vibration, and emanate smell associated with gasoline. Plus these battery cars were preferred as they did not require a manual effort to start or gear changes.

Things changed with the invention of the electric starter by Charles Kettering in 1912, making gas cars to travel faster and longer than their electric versions. Plus added discoveries of large petroleum reserves worldwide, led to the wide availability of cheaper gas. Again gas prices soared between 1960s-1990s, creating interest in electric vehicles once more.

Gas Giants Overpowering Electric Aspirants
Throughout the EV emergence, there has been a constant pressure exerted by the oil industry, who was always afraid of losing its monopoly on transportation fuel over the coming decades.

There were reported figures of low consumer demand and hyped advertisements about the success of gas driven cars in the US. Then due to lack of infrastructure and finances, EV models were later destroyed or donated to museums and educational institutions.

In fact even now, for an undisclosed sum, oil giant Shell bought German home energy-storage startup Sonnen in 2019, in order to utilise their assets to Compete against Tesla and it’s batteries.

2000s – Present
The emergence of MOS (metal-oxide-semiconductor) technology and lithium ion battery led to the development of modern age electric road vehicles with less power losses.

The likes of Japanese Nissan Leaf, American Tesla Model X, German BMW i3 and South Korean Hyundai Ioniq Electric became popular electric cars, with more attempts at installing their respective charging stations. Additionally, Chinese and Taiwanese firms became manufacturing in e-bikes like the Gogoro series and Okinawa iPraise.

Electric Vehicles become mainstream in Europe with 121% sales in 2020

electric car

2020 has been a year of continuous growth for the European plug-in electric car market as the latest reports by Electric Vehicles (EV) Sales Blog suggest a near-record 74,663 new passenger plug-in car registrations. This is 121% more than a year ago and the first three-digit growth rate since 2015. Consequently, 2021 is likely to be a tipping point for the EV market.

Crux of the Matter

What Do the Numbers Say?
Electric car deployment has grown at a speedy rate in the past date, with the global stock of electric passenger cars passing 5 million in 2018, an increase of 63% from the previous year. Currently, all-electric cars stand for 52% of total plug-in Electric Vehicle sales, compared to roughly two-thirds in 12-months of 2019. That’s because plug-in hybrids rebounded and are growing much quicker – by 174% year-over-year, compared to 89% in the case of all-electric cars.

Who is the Most Popular of Them All?
The ranking system is interesting to study since there have been many changes in 2020 when compared to the statistics observed in 2019. The Renault ZOE set its new record of almost 10,000 sales (9,782), and was followed by another French model, the Peugeot e-208 (3,897) and falling not far behind is Volkswagen e-Golf (3,296), Nissan LEAF (3,177) and Mitsubishi Outlander PHEV (3,149).

The biggest gain among manufacturers seems to be achieved by the PSA Group, which sold more than 12,000 plug-ins in January. European consumers being so interested in small electric cars is a good sign for the future of electric vehicles on the continent.

Forecast of an Electric Surge
The current production forecasts show that most carmakers are ready to embrace electrification and are leaving behind the ‘technology neutrality’ approach, focusing on scaling up electric car volumes instead. After several years of timid growth, the number of Electric Vehicle models produced across the EU is about to surge to new heights. 60 battery-electric (BEV), plug-in hybrid (PHEV) and fuel cell (FCEV) models that were first available at the end of 2018, have reached 176 models in 2020 while 333 models are now expected in 2025. Most importantly, the mandatory EU CO2 target of 95g/km would be fully implemented by then.
