The rumors claimed BYD’s solid-state batteries have an energy density of 400 Wh/kg, or nearly twice that of current lithium-ion batteries.
The report also stated that BYD’s solid-state EV batteries set a record by gaining a 1,500 km (932 miles) range in just 12 minutes of charging.
According to the report, the test charged the battery to only 80%, claiming the total EV range could reach upwards of 1,875 km (1,165 miles).
BYD did not confirm anything of this report, so take it as a rumor for now. Still this sounds pretty impressive to me.
Oh cool new battery tech! What’s up with the nearly irrelevant title?
I didn’t change the title, although it sounds confusing to me.
The report said all these things about 1100KM+ range etc but
BYD shut down the rumors, saying in a statement on June 23 (via CLS), “Currently it is unknown, and the first model and parameters are not officially reported.”
By the way, the current BYD Seal has an 82.2 kWh battery and a CLTC range of up to 650 km. If the prototype truly achieves 1,875 km, it would imply a battery capacity of roughly 240 kWh—nearly three times the current pack size.
The density is twice as much, so only 50% more battery mass, not impossible.
With a charge time like that, I think I’d rather have a 500 mile range and a cheaper vehicle.
It seems like a waste to drive with a battery that could power my home for a whole month. My personal guess is that even if possible, very few cars will feature batteries larger than 100 kWh.
If you have the right hookups you can literally power your house with it in an emergency though, and more and more people (like myself) would love a nice little ERV/vanlife situation.
