The executive vice president of SAIC, MG’s parent company, stated that the automaker will begin introducing solid state battery (SSB) technology into its line-up as early as next year.
Toyota, for example, has previously said that it hopes to bring similar technology to market by 2028, while Volkswagen has partnered with US research company QuantumScape. The pair have said they have reached an agreement to industrialize the technology, but no actual timelines have been set.
China AGAIN steals a march on competition.
Charging time drops to 10-15 minutes. And solid state increases the range of an EV.
Unfortunately, Yu Jingmin didn’t provide any details about battery specifics, but sister company IM Motor has already revealed its new L6 Saloon, which uses an early example of the company’s solid-state battery research.
I wonder if the Saloon comes with a fully stocked bar?
The result is a car that can achieve a 673-mile range on China’s Light-Duty Vehicle Test Cycle (CLTC) and can add a staggering 249-mile range in just 12 minutes from a high-powered rapid charger outlet.
Maybe if they had a lower range it could charge in 10-15 minutes. But with the larger range it seems like adding just 500 miles (~75%) will take at least 2x as long or 20-30 minutes.
249 miles is about 37% of the 133kwh pack, or 50 kwh. To charge that in 10 minutes requires 300 kw sustained, which is possible since we already have 350 kw chargers.
Isn’t charging to 100% all the time detrimental to battery life?
The video below suggests that “Cycling near the top of charge (75–100% SoC) is detrimental to LFP/graphite cells. Our results show a correlation between the average SoC of battery operation and capacity fade rate, meaning that the lower the average SoC, the longer the lifetime…,”
So keep charge to below 75%. Of course the article is about Lithium iron phosphate (LFP) batteries and thus may not be applicable to solid state batteries.
Sure, but newer battery tech is supposed to fix this.
But even if it doesn’t, most of the time people will slow charge at home or work and only need the extra long range and extra fast charging for a couple of weeks out of the year.
And it they have no access to chargers at home or work they can do a fast charge to just 80% as needed.
