Another engineering consultancy in Trollhättan gets a contract from NEVS

Today I’ve found an interesting piece of news on the ttela site. And why is this so interesting?

Well first of all it may help us to forget for a minute the bad news from yesterday, and secondly it has zero relation to EVs. 🙂

According to the article, NEVS has assigned TechROi Fuel Systems to develop fuel tanks for their cars.

TechROi fuel systems was formed last summer and its employees are the former Saab Automobile AB Fuel system department engineers.

Even their Fuel systems lab is the former SAAB Automobile AB fuel systems lab that is located at NEVS development centre area.

But not only NEVS is interested in their knowledge. Several other companies show interest in their own tank technology based on a concept they developed during their time at SAAB.

From the TechROi site

TechROi Stainless Steel Tank.

Stainless Steel Fuel Tank Concept
Our Tank in Saab Phoenix

Saved more than 3 kg weight and gained 2 liters of volume compared to equivalent plastic tank
Easily meets LEV III
Investments are down compared to previous projects with about 50-70% (type-specific equipment)
Engineering cost reduced by over 50%
Time to market is reduced by at least 50%
Logistic costs down by 70%
The concept is optimized for volumes below 200 000/year

It is interesting to hear that a stainless steel tank can be lighter and cheaper than the current plastic tanks. But I think that not much was impossible foe the troll in Stallbacka. 🙂

  1. Unbelieveable, who could come up with an idea like that,. This is simply another Saab milestone. These plastic tanks are crap. They are so soft that I crashed mine without noticing until the car was inspected at service. It probably happend by backing onto a stone.

    • Not always,
      some EVs will need to have a petrol heater to have a normal range in the winter. Those EVs will also need a tank. 😉

      • Certainly, an auxilliary heater is the solution for lack of heat in EVs, but does that really require a high tech tank developed by a consultancy company? I think the agreement clearly points to hybrid technology. Fuel cells are less probable, since the required hydrogen tanks are very different from liquid fuels tanks, and must bear 700 bars of pressure. Conventional cars are also less probable, since the tank for the present 9-3 is already finished and in (stalled 🙁 ) production, and the Phoenix is still announced as a next generation electrical thing.

      • “Saved more than 3 kg weight and gained 2 liters of volume compared to equivalent plastic tank”

        Why would this be relevant unless it’s a normal size tank? 😉 A heather requires so little fuel they could hide a 10 liter plastic one in there if that was the case.

          • Oh but we know 🙂
            At least I didn’t think that all the fuel sitting in the brand new tank on a new EV Saab would be meant as compensation to the individual towing us home after the batteries are dead.
            Although with a cleaver hose system that could work. Also very hand for someone who’d like to borrow some gas “without permission” 😉

  2. A positive sign. Nevs, we need more where that came from and make sure that tank gets filled with gas/E85 🙂

    I remember that day in july ’93 when the ng900 was launched. Mounted on a spinning platform on top of a truck. We thought it was super cool. What if NEVS would do the same, but with a concept car?
