Fisker Family,

Really excited to read about the quantum leap of this
'next generation' Silicon Carbide Inverters

When Henrik stated that Fisker Inc can make late-call decisions
(12-18 months) before SOP, this is exactly the kind of decisions he means

ADVANTAGES of SiC Inverters

~ Less weight (better mileage range & handling)
~ Lots more power and torque (happier clients)
~ Enables use of smaller battery pack (saves monies & weight)
~ Less cooling needed (saves cost & weight)
~ Faster Charging Speed (less downtime at Charger station)

Do we know this technology is being used in the Ocean?

Something changed. Originally, Fisker was estimating 300 miles per charge. It was fairly recent that they upped it to 350.

i think they were also saying charging up to 150 kWH and I have recently seen they will be able to charge up to 250 which hopefully will make it very competitive

@baydreamer
Does this mean that Fisker is using equipment before it's been thoroughly tested?
Not at all. Fisker Inc is at the forefront of technology and can quickly (compared to OEM car makers) use the latest, greatest tech!
Tesla & now McLaren both use SiC Inverters

I don't mean just the converters; I mean in general. For instance, Henrik said that the reason the Ocean will get more miles per charge is that he chose a newer battery than other companies. I'm not trying to be a nay-sayer. Obviously I want Fisker to succeed and I want a Blue Planet Ocean in my driveway to break up my street's depressing sea of white.

Tesla is using CATL for their LFP batteries now. I'm guessing it's probably the same cells going into the Ocean Sport. Ford and VW and many Chinese brands are also using CATL's LFP and NMC battery cells. So I don't think it should be a problem. CATL seems to be a well run company.

The benefit is supposed to be more agility when it comes to adapting improved technology. Larger companies, especially legacy car makers use notoriously dated technology because it is both cheaper and they have less agility to change their production line. The point of this is not that Fisker is beta testing new technology. These companies are still going to test their tech and only release it to integrate into products once it is ready, ideally.

Whats the significance of these inverters ?
To dumb it down to the purest level, think about the difference between a crappy 100’ extension cable for your lawn mower and a nice new big gauge extension cable. The bigger the wire the better your lawnmower can cut grass and make the dog poop fly, without making the mower get hot or tripping a breaker. It’s more efficient.

Your new EV needs power from the grid which is AC (alternating current). Your onboard charger then converts it to DC (direct current) for the battery which can only store it like a big 9v battery. The faster it can do that, the more effective the power transfer. So, a shiny new high tech silicon inverter can do this faster, more efficiently and way better than the older chargers in your older EV. Therefore, your new EV with this tech can charge faster because it can move the electrons to your battery faster.

The car needs to transfer power to the motors once it‘s on the road. My wife leaves the garage and starts off on her stop light Grand Prix to the coffee Shop. So now the inverter now reversely takes the stored DC energy and converts (via the new inverter) it back to AC for the motors. So when the light turns green 🚦my wife romps on it and since the inverter can pass more current the car can move faster therefore increasing the poop eating grin on my wife’s face :D. It’s better, makes her happy and makes my life better.

The new inverters are lighter too, so less weight makes the car faster. The tech is the electronic “switches” inside which switch faster, making power transfer faster and with less heat. If the transfer is faster, then there needs to be less muscle behind it, so a slightly smaller battery can be used.
