Polestar has introduced that prototype cells fitted to a model of its upcoming Polestar 5 flagship EV have been in a position to do a 10-80% cost in simply 10 minutes.
Polestar mentioned final yr that it will place the tech in a prototype Polestar 5 gaining 100 miles in 5 minutes—this undertaking—by 2024, and it seems to have exceeded the unique goal. Within the drivable Polestar 5, fitted with a “specifically commissioned” 77-kwh battery pack, the pack has demonstrated that cost price.
With this undertaking, Polestar fitted StoreDot’s “100-in-5” XFC cells into the prototype Polestar 5 through a prototype Polestar battery module. It claims to have charged the ensuing pack at a beginning cost price of 310 kw and a peak of 370 kw.

The cells aren’t the all-solid-state cells that Toyota, Nissan, Honda, and others are concentrating on for later within the decade. However these “silicon-dominant” cells, delivered of their first take a look at samples for automakers in 2021, are an extra evolution of the lithium-ion cell tech frequent in EVs. StoreDot says it’s reworked them “by innovating and synthesizing proprietary natural and inorganic compounds, optimized by Synthetic Intelligence algorithms.”
Polestar underscores that whereas power density is on par with present nickel manganese cobalt (NMC) lithium-ion cells, these don’t require “specialist cooling methods.” The businesses have beforehand mentioned that this side might minimize lots of of kilos of weight from full EVs, however it’s unclear if which means the take a look at Polestar 5 goes with no liquid cooling system.

That mentioned, it’s unlikely that the tech can be put in in a manufacturing mannequin anytime quickly, and the manufacturing Polestar 5 will get a distinct battery pack. With this take a look at Polestar 5, the model now must see if such a cell can be sturdy and dependable as a part of the thermal calls for of a big electrical automobile battery pack. In 2022 the businesses mentioned that StoreDot was looking for mass-production of EV-sized batteries of such tech by 2024.
BP is an investor in StoreDot, and Polestar additionally holds a stake; a “strategic collaboration” with Volvo can even end in real-world testing with that associated model.
