Aptera battery size is no longer so important

While driving, an Aptera also has the huge advantage of 40% lower current to accelerate/cruise, & its low weight also means less regen current. So there should be 40% less heat for any cooling system to dissipate.

Correct. Length of time at high current in (charging, regen) or out (acceleration or uphill) is not as good for battery life as low current. But it's of course relative.

My own BEV's battery is rated to retain 80% capacity for 211,000 miles when charged at "0.5C", which is faster than any Aptera will charge on L2.

0.5C is equivalent to Aptera's 50kW DC charge speed on the 100kWh model.

On the shorter-range models it's proportionally less gentle, but keep in mind that they are DC charging for VERY short periods: Only 18 minutes at 2C from 20% to 80% for the 25kWh, & likely also doing so only for rare road-trips, since if road-trips are common you likely got the bigger battery.

No matter what, Aptera's extreme efficiency gives it the huge advantage of adding more miles per hour without subjecting the battery to longer charge times or harsher high charging current.

i rerember fast charging is worse for battery lifetime like quicker accleration is, I'm not sure.

Right, & for daily use even current EVs recharge the average US daily drive just from an extension cord in a standard wall outlet during 8 hours of work OR sleep, or a FIVE TIMES AVERAGE drive from a dryer outlet.

Aptera already recharges a 2.5 times average daily drive from the wall outlet or 12.5 times average drive from a dryer outlet.

Charge speed is really only important for road-trips of greater than the car's range in a single day. Maybe it shouldn't even be important for that:

• If you do long trips infrequently, then just rent/borrow/swap like I do (or drive to the airport).

• If you do long trips frequently, then just get the Aptera that covers that range without charging.

Even for those without a plug at home OR work, it's not batteries that are the limiting factor, it's charger speed: A week's driving will recharge in pretty short order, once every car & every former "gas" station are required to have 350kW chargers.

I wish them success. We need to remember that charge time is just one of many requirements for an EV's battery. How long do they last? How much will they cost? How much energy will they hold per Kg? Lot's of unanswered questions.

The big difference with the well-known “energy cells”, as Schein calls them: Varta’s 21700 cell is said to be able to be fully charged in six minutes. “No other battery in this category on the market offers this feature yet,” says the Varta CEO.

Neither do they yet!

Interesting but, I'm not waiting until 2024 to get an EV
