Fisker Turns To Ricardo For 800-Volt Charging & Powertrain

NOV 1 2017 BY MARK KANE 26

The upcoming Fisker EMotion is to be one of the first electric cars with 800 V electric power-train (assuming it actually arrives as promised in 2019 of course), including its proprietary 800V Ultra Charger, 800V Battery Pack and e-axle systems.

The integration of all these components was entrusted to the Ricardo, which has become a strategic partner for the project.

The EMotion was promised to be equipped with a 145 kWh battery (21700 LG Chem cells), good for over 400-miles (644 km) of range. Charging specs are also set high, with a 9 minute recharge good for ~125 miles (200 km) of driving.

One of the ways to achieve such result, is to improve efficiency through the use of roughly twice higher voltage – around 800 V.

“The EMotion powertrain is based on an 800V high voltage system architecture, which includes the motors, inverters and power electronics. LG Chem will deliver 21700 cylindrical cells based on NCM chemistry that are structured into Fisker’s high energy density battery pack. The exact details of the proprietary charging method are still held closely inside Fisker and will be debuted at the 2018 CES. All vehicle system controls will also be part of the Ricardo Fisker partnership.

The benefits of a 800V electrification system are thinner lighter cables cables, smaller  more efficient motors, lower system weight, less heat generation, lower manufacturing costs, faster charging and higher power throughput.”

The public unveiling of the Fisker EMotion is schedule for 2018 Consumer Electronics Show (CES) in Las Vegas in the Quanergy Systems, Inc. booth (#3315).  InsideEVs will be attending the show ahead of its officially opening, and we hope to be able to get an early look at the offering.

Henrik Fisker, founder and CEO of Fisker Inc. said:

“For the past year, we’ve been in stealth mode talking about our technology without discussing partners. With CES being the Global Debut of the Fisker EMotion, we are now starting to share who our partners are. Ricardo is, without question, a global leader in powertrain integration. We are setting the benchmark high with the EMotion and Ricardo is yet another partner that will help make  the EMotion truly a world-class vehicle.”

Ricardo US President Paul Rivera said:

“I am pleased that Ricardo will be working with Fisker Inc., to overcome the challenges associated with integrating ultra-high voltage, energy storage, components and wide band gap semiconductors. We look forward to partnering with Henrik Fisker – arguably one of the most well-known automotive designers in the world – and his team to bring the Emotion premium electric vehicle to market, while generating advanced technical solutions that benefit our customers.”

Tangentially related…when’t the Karma Revero going to hit the monthly scorecard? Or am I not reading it correctly.

We actually recently got some data on sales for the past couple months, and reached out to Revero to see if they wanted to be included in the scorecard on an ongoing basis, and also if they wanted to provide that information directly to us in the future.

They asked to not be included at this point in time (we suppose as their volume production is just now getting worked out), and as such, with things just kicking off, we have offered to not make those numbers public.

Fair disclaimer: they are mostly immaterial to the net number right now, but once they are most substantial we would/will include them

Frankly I can’t see these automakers’ (VW ‘s Porsche Mission and Now, Fisker) obsession with the essentially nonexistent 300 kw charging. Neither car is available today, and for many the car as is would be super great even if it had no fast charging at all. Certainly whatever connectors to the battery could be implemented to allow future addition of fast charging when such systems become available. It also does not need to be added that some buyers will not want to pay for a feature they’ll never use. As my own case proves, I definitely wanted ‘public charging availabilty for my Roadster’ (I wouldn’t purchase the car without it, and I NOT purchasing Tesla’s standard ways of charging the car, using the J1772 adapter 100% of the time for ANY charging), but didn’t need or even could use any DC fast charging (so called ‘Level 3’) facilities. Same with my BOLT ev. A plain, standardized CCS or Chademo – whichever the automaker is committed to – fast charging solution, as an optional extra, should more than satisfy the vast majority of people. I wonder how many of these announcements are simply back handed ways of free advertising, and neither… Read more »

People just don’t get that they can charge their cars in their garages and will always start out with a full “tank” in the morning and therefore will not need to quick charge on trips 99% of the time, so the quick charge time is mostly irrelevant. It’s a huge psychological barrier for them when they hear that a charge takes one our, whereas filling their tanks just takes five minutes.

They should consider partnering with Tesla to get their customers access to the Supercharging network.

If Tesla upgraded it to support 800v charging, future Teslas could benefit as well.

No one is going to partner with Tesla to use a non-standard proprietary network. The Supercharger network’s cost will eventually bring Tesla to it’s knees.

You Know Nothing………

I doubt tesla will go to 800v anytime soon, I also doubt that Tesla will license their superchargers to this company.

In other news a Fisker Karma went up in flames in San Diego while in a garage a couple weeks ago. Odd that the EV media never picked up on it. You can physically see the battery cells catching on fire. If I recall correctly, the previous fires were all due to the cooling fan and low voltage systems (hurricane sandy). In those 12v fires you can physically see the space frame melt around the HV pack- while the pack and the tunnel were close to intact.

Bawahahaha! This is the perfect response. 😀

One good thing I can say about Henrik Fisker. He is a great designer, this is a good looking car.

I Disagree…He worked at Tesla & got Fired for Bad Designs. Among other things , he was there to take ideas with him to serve his own Purpose.

So true. GM should hire him to style their EVs. That way he would advance the acceptance of EVs instead of producing EVs that spontaneously combust to reinforce the EV stereotype promulgated by the fossil fuel industry.

Nice looking. But I don’t see it breaking the 100 monthly barrier in sales.

It will Positively Fail ! Just Like The Previous ..This Guy sucks in a bunch of people for money . He makes money every time no matter what happens , Only the suckered investors Lose . He never loses .

Ricardo did much of the engineering on the previous 2012 Fisker Karma we saw how that all turned out

Paul Rivera the US president of ricardo previously worked at Quantum Technologies during the time they were doing work for Fisker Automotive.

Maybe HF went into his rolodex, but I recall him saying that they were going to own the battery technology and powertrain technology. This whole engagement reminds me of Fisker Automotive, outsource everything but the design. What exactly is proprietary about the EMotion other than the exterior?

This looks like a repeat of Fisker Automotive all over again, with no real core IP.

If people fear riding in a 800 VDC car, then they forgot that in the 1950’s to 1980’s TV sets in every home had a CRT that used up to 25 KV (25,000 volts). I did plenty of TV repairs and never got any shock. Good engineering and OSHA standards will protect these HV cars.

I don’t fear riding in a Fisker, I merely fear sleeping in a bedroom OVER the garage which will catch fire if its a fisker.

I wonder if it will be able to fast charge at the 400V stations that you will actually be able to find instead of they mythical 300+kW ultra fast chargers that run up to 1KV.

I don’t see why they couldn’t isolate half the battery pack on a 400v system and charge that portion then isolate the other half.

Or could use a step up converter.

Would make more sense to have a separate set of charging contactors for half the pack.

That sounds like a balancing nightmare.

I don’t think any HV battery out there lets you balance on DC voltage. You can really balance at any SOC if you have a good historical reference of normal cell voltage deviation (i.e. BMS lookup table) based on SOH. It is all about how the BMS is integrated.

I doubt they will go with a boost converter because that will not make the vehicle compatible with any of the DC charging protocols out there.

800V seems like the new standard that future cars are all gravitating to. I keep seeing it over and over. That would be a massive shift forward.

Yes many seem to use 800 V although there will likely be some extra doubling before things settle. We can expect 1600 V and 3200 V to follow, although I would rather go for a 10X and adopt 4000 V straight away.
Insulators haven’t been standing still in all those years, we now have cables that can carry 200000 V. Of course there are some other aspects to take into consideration since once cables are small enough and motor densities already optimized higher voltage start to become a source of potential problems instead of a bonus. But for now, at 800 V we are still not there yet, not at 1600 V neither; at 3200 V some extra precautions are needed and above 4000 V the problems start to overweight the returns.
Counting on some technology improvements we could go a little higher but there will be some conservatism resistance, so we will likely end up with 3200 V. So still two doublings to go.

Odds say this car never makes it to the road and the company goes bankrupt.

We are still fixing all your engineered mistakes on the first one!

Third try is the charm Henrik!

Fisker engineered barely anything in the first car. It was outsourced to a bunch of third party companies. All fisker did was pay the bill
