From Jalopnik, November 9:
Slow charging EVs may soon be a thing of the past, and Polestar says it's 'production ready'
Polestar has been working to develop a new extreme fast charging battery, capable of topping up 100 miles worth of charge in just 5 minutes. The Chinese-owned Volvo sub-brand announced during its Polestar Day event, that a Polestar 5 prototype has already been fitted with these batteries, and the system is essentially production ready.
In an average EV, 100 miles equates to around 30 kWh of energy, meaning this prototype would be accepting juice at a rate of around 350kW. There are some chargers already on the market which can deliver electricity at that rate, but they remain few and far between, and there isn’t much on the market that can take full advantage of them. At its peak charging rate, Lucid claims its Air sedan can match this Polestar prototype on power, and the company claims it can get a charge of 300 miles in just 20 minutes. The Hyundai Ioniq 6 and Porsche Taycan use advanced 800v architecture, and by comparison can only accept around 60 miles of additional charge in the same five minutes.
Polestar partner StoreDot claims to have “revolutionized the conventional li-ion battery by innovating and synthesizing proprietary organic and inorganic compounds.” The company exists solely to investigate speeding up EV charging rates. It claims that it is on track to reduce that five minutes per 100 miles rate down to just three minutes by 2028, and is aiming for two minutes in 2032....
