I will replace my old gas car somewhere next year with an EV; so as circumstances may push me to buy two new cars at the same time, as my GF also will need one then, I am looking into buying two Apteras with relative short range, as even 250 miles are way more than our daylie commutes. But I would hate to miss the fun of having an EV, aka the strong acceleration and recuperation.
So I would like to know how the different batteries of the Aptera can handle the power of a 3 wheel setup?
can even a 250 mile battery deliver the full 150KW of power at under 20% of charge? Is the recuperation of a 400 mile version stronger than a 250 miles version?
Battery size Vs Power depends on the evolution of Battery technology. the raw elements used in batteries today may be needed in the new breed of batteries of tomorrow. I look for everything I can on internet about batteries, Aptera is on front line or beginning to. why not try to keep this front runner in the lead of the pack in size Vs Power by planning ahead. don't need EPA giving trouble down the line. any profit from cost effective Battery strategy can make Aptera a leader in the field of the battery size Vs power.
Aptera once again has a 250% advantage: 250% of the range with the same battery size & environmental impact & recycling needs.
By comparison, my current BEV’s 24kWh battery goes "only” 250% of the average US daily drive (Aptera goes 625‰) & my battery will ”only” continue the avg drive until a few years after I'm dead.
My point is that even ancient 2013 tech is great, & Aptera is 250‰ as good as that.
Battery technology is changing faster now then ever before, need to make plans now for many things to come. Prepare for the change and avoid land fill problems. But use so longevity of Aptera is preserved.
What about recycling Batteries Problems so the waste products of vehicle are minimal and cost of operations is benefits.
For many dual motor EV's, the acceleration is limited by the max current output from the batteries, rather than the motors. Drawing too much current from one battery cell will degrade its lifetime and could damage the cell. But since Aptera requires ~25-40% of the current for a given acceleration compared to a typical >4000 lb EV, even the smallest 25kWh battery pack should be sufficient. The smallest battery pack is also lighter and requires even less current. Aptera has said they expect the 25kWh version to be the fastest. Aptera may be traction limited with all season tires, so it may not actually pull 6C.They will need a good battery management system and good battery cooling system, though.
I believe the primary question is a VERY good one, essentially "Can the 25kWh pack be discharged at 6C?"
AWD's three 50kW motors drawing 150kW total divided by the pack's 25kWh is a pretty high 6C discharge rate.
If, for example, it's limited to 4C, the max power would be 100kW & the 40kWh pack's 125kW at 4C should provide better acceleration (25% more power & only 7.5% more vehicle weight).
The formula to calculate Power: P (Power in Watt) = I (Current in Ampere) x V (Voltage)
For purpose of explanation let us say the Voltage is 500V
So 1A x 500V = 500 W then 10A x 500V = 5000W or 5KW then 100A x 500V = 50KW
Thus in the 2 wheel drive version the Aptera will consume 100KW at maximum constant speed (50KW per motor) and the all wheel (3 motors) will consume 150KW at maximum constant speed. This will be true regardless of the battery pack capacity installed.
The battery pack capacity installed actually determines the available range. Let us say the battery pack is rated 500V 100Ah. This means the battery pack will be able to supply 100A for 1 hour. If you put 3 of these battery packs in parallel then you will be able to draw 100A for 3 hours.
This means that if you want to brag and show off your APTERA's quick acceleration and high speed a few times to 3 or 4 of your friends you better have a fully charged battery pack if you have the 250 mile range battery pack installed as these short bursts of speed will surely impact the available power left after you had all your fun and games with your friends.
