News about the EV projects
On November 19th Andrej bacame a fellow of
World Technology Network and had
at World Technology Summit:
Our goal in 2015 was to push the range of Metron 7 over 800 km driving at normal road conditions and traffic. We did it by improving efficiency, reducing weight and doing some additional work on batteries together with cell supplier Kokam
We did it: Winning WAVE 2015 and setting a new record of 826 km per single charge!
On 12th of october we started our
journey from Bled to
Dubrovnik without charging. The goal was to prove that it is already
possible to drive normal speed at normal trafiic conditions and reach more then
700 km of range using today's technology.
There are rumours that we have overfilled the trunk with
batteries to reach such a range. The truth is: yes, we have overfilled the
trunk, but not with batteries :)
Plot, mistery or coincidence????
As you know or maybe not we have won Rallye Monte Carlo des energies nouvelles 2013 both in category IIIA "electric vehicles" and category "consumption". Till then Tesla Roadsters were dominating that rallye because the route was too long for all other cars. Except for our Dacia that finished first leaving behind two Tesla Roadsters. At next EV Rallye (Mendola Italy) our team was called by the organizer because they have received complaint by someone that our car is not street legal. After presenting the documents (COC) that the car is street legal, we were allowed to compete. We were leaving behind Tesla again and in the middle of the season (in July 2013) FIA released new Regulations that do not allow cars converted to electric to take part at rallyes in category IIIA.
I always thought that it was a coincidence till we noticed a month ago that our victory in category IIIA from 2013 somehow dissapeared from the official RMC page "Rallye Archive"! If you do not believe, check this page: http://www.acm.mc/documents/6/EN-26-Classement_Combine_IIIA.pdf and then try to find this page or this result at their new Archives page: http://acm.mc/en/rallye-monte-carlo-des-energies-nouvelles/archives-du-rallye/edition-2013/ or anywhere at RMC pages. And yes, it can still just be a coincidence that someone not being carefull enough deleted the link when making new "Rallye Archive" page.
But then I have read this https://speakev.com/threads/tesla-battery-range-degredation-forcing-return-to-petrol.3725/ and now I am no more sure that all this was a coincidence... It seems that the one whom all EV enthusiasts have adored the most has turned out to ba a "Fallen angel"...
If somebody could find out what or who is behind these coincidences, I would be very glad to receive your message. I still hope our idol has not turned bad...
At WAVE 2014 Metron 7 wan the "range competition" leaving
all Tesla cars at least 130 km behind! Battery capacity is the same as in Tesla
S, so it is the efficiency that makes the extreme range of Metron 7 possible.

27.2.2012 - Piki 3 is driving!
Short movie about Superpiki
20.12.2011 We use our electric cars in summer heat and winter
cold. But in winter conditions the range of Dacia that is in summer at 350-400
km drops to 200 km because of colder batteries, winter tyres and electric
30th of September we drove with our Dacia Sandero from our home to Starigrad close to Zadar at Croatian coast.
We did 340 km and still had 20-25%of the energy left (we will
burn it in next 2 days to see the final range) driving at normal speeds with 2
persons and all holiday luggage. Average speeds were between 60 kmh and 100 kmh
depending upon the road and speed limits (though we have been slightlly speeding
and hoping not to be punished for 5-10 kmh too fast). We have been accompanied
by a team of Croatian journalists from Auto motor i sport driving by with diesel
Dacia Sandero. Report will be published on 6th od October. When we finally
plugged in the car, we drove 391 km and had voltage of 3,36V per cell (about
21. September 2011 - Piki 1 has a new owner (it has been
sold) that lives in Pisece (near Krsko, Slovenia). The new owner is also quite
well known in the solar industry as an inventor and manufacturer of the state of
the art high accuracy sensory solar tracker controllers
Superpiki - new project together with company
Second Dacia Sandero driving powered by Iskra motor - july 2011
13. and 14.5.2011 -
12.5.2011 - Bolt gets TIM 600 MES DEA controller. The result are
sport car performances !
We have finished one more electric car -
Dacia Sandero Elektro
that made first 7 km drive for Christmas 2010. Range is between 250
and 400 km! Energy consumption of Sandero and Smart is now being measured by
Elektro Gorenjska and SODO and we will have quite exact date of two cars
charging at two different ways - "smart" and "stupid" charging
Working on a joint project with company Isolants Victor Hallet
to start small series conversion of Smart in Belgium November 2010
All cars have been presented at
5th Technological conference
29.9.2010 Smart made its first electric drive - First
drive - video
31.8.2010 Converting Smart to electric power
Preprototype of first series built Slovenian car
Chebela has done first 20 km. It is powered by Iskra motor and has 15
Thundersky cells of 200 Ah. It has been built for testing purposes on the basis
of Ligier car.
3.7. Opening of 5 EV filling stations in Slovenija:
Jezersko, Preddvor, Bled, Bohinj and Kranjska gora
Slovenian EV fleet grows and so does the number of charging stations. Bolt is now equipped with vehicle to grid technology (small 250W pilot device), so we demonstrated power transfer from our car to the grid.
More power for Bolt: 4 additional cells raise the nominal voltage to 208V and increase power and range for 8%. We reduced the weight for 20 kg by removing unnecessary parts, so we keep the same weight though we have added more cells. 3.7. we drove 249 km without charging including about 70 km of highway and Jezersko uphill.
Austria - EV meeting at Worthersee 21.-22.5.2010
May 2010 - Working in China- converting BYD F0 to EV
Video of its first electric drive (9Mb)
Fast charger is finished - now Bolt can be fully charged in 5
We start a new project - conversion of two 5 door family
cars to electric power. The goal is to convert a car for less money and get good
performances at the same time. One car should have a range of 120-150 km and top
speed 130 km/h with cost below 30000 EUR (new car included), the
other should have a range of more then 350 km and top speed above 140 km/h

Opening of new charging station in Kranj 9.12.2009
Bolt refuelling in Klagenfurt 4.12.2009 - two electric cars
at the same time!
Both electric cars showed to public at the Institute Jozef
Stefan in Lhubljana 8.10.2009
New EV "Bolt" has been finished on the 8th of september 2009 and has a range of 250 km and top speed of 150 km/h We dismantled the EEspace and the components were used in the new car - the Bolt
Bolt filling electricity at EV filling point in Ljubljana
Electric km stand of The Bolt 16000 km (21.12.2010)
Electric km stand of R5 Elektro 29000 km (21.12.2010)
Electric km stand of Smart Piki: 1500 km (21.12.2010)
20.4. 2009 We took LiPo batteries out of E Espace and put
it in R5 elektro. It beame a real rocket and has an incredible range of about
250 km! E Espace will be dismantloed and the component used in a newer and more
attractive car. The generator will not be installed as with LiPo it is no longer
E Espace has made a 135 km trip to Austria over Ljubelj
mountain pass and back. In Celovec we tested if the filling points for electric
cars are really there or this is just a tale for the media. We found one at
Wirtschaftskammer and filled in some energy.
PV has been finished, now starts the bureocratic battle to
connect it to the grid.
11.3.2009 We are building a bigger 3,3 kW PV power
plant equipped by sun tracers
SAT Control. The
power plant will produce enough clean energy to drive our E Espace and R5 20000
km per year
28.2.2009 More power for E Espace - Miro Zoric is upgrading
the regulator to 400 A transistors that will feed the motor with more power. How
much more and what will be the performances is still unknown as it has to be
tested not to burn the motor.
We use both cars also in winter time. Winter experience:
lead acid batteries of R5 lose 20% capacity at freezing point temperature (compared
to room temp), LiPo of E Espace about 10%. Without auxilliary cabin heater it is
impossible to survive driving -:) We must take care that LiPo are not charged
below freezing point as it can damage them. As we live high and start our drive
with descent, there is also a danger of regenerative braking when too cold. That's
why we keep E Espace in a garage (non heated) during the night.
12.10.2008: R5 Elektro finished. It was the first Slovenian
electric car built by Miro Zoric in 1993 and now "refurnished", improved and
back on the road again.
5.Sept 2008:Another electric car is almost finished
- 192V 105 Ah lead acid Trojan batteries, 40 kW Stoja electric motor, range 30-65 km, top speed 140 km/h
18.August 2008: Electric defroster/heater 100W installed as foggy and rainy days will come. Motor cooling has been improved, no more overheating under full power during hot days
23th July 2008: We drove 193 km on pure electric drive
without charging the batteries and they still had 3,56V per cell what means
about 20% of the total capacity!!! The rear part of the car with battery
compartment has been refurnished and now looks like this:
14th July 2008: 4500 electric km done with E Espace till now (Diesel generator has not been used since we installed LiPo batteries). We use it for every day driving, no problems till now! We are working on a proper charger for Li-Po and till we do it, we charge them in series, check the voltage of each cell and every 10 charges equalize them half manually. We had some problems due to extremelly high temperatures outside while frequency regulator is temperature limited to 66 degrees Celsius and when outside is almost 40, the difference is very small. So cooling system had to be redone...
June 2008 Another car has been converted to electric -
a small city car with cheaper lead acid technology. Actually this is not a new
conversion, but the first Slovenian EV done by Miro Zoric in 1993 as a prototype
for Renault factory in Slovenija.
18.5.2008 - EV car gathering in Austria was a good chance
to meet other people developing the same idea and to show the people that there
already are electric cars on the roads. About 30 different vehicles gathered and
the organizer (Eurosolar) prepared many activities like evening meeting in WiFi
hall, visit of Solar modul factory, Kelag power plant etc. E Espace did a non
stop trip of 130 km passing a mountain pass Jezersko (1200m). Overall it did 300
km in 2 days.
Parade of electric vehicles in Austria 16.-18.5.2008
Those 4 boxes contain more power then 1000 kg of lead acid batteries! We bought excellent 200 Ah Li-Po batteries from KOKAM and they work perfectlly even without BMS (of course with manual control)
7.5.2008 - Kokam Li-Po batteries have arrived - 200 Ah 3,7 V cell with weight of only 4 kg!
May 2008 - E Espace is homologated and now has 150W of PV cells installed. Next week we expect Li-Po batteries 200 Ah 192V that will increase the EV range far over 100 km. Up till now 2500 km done without troubles, max.speed 120 km/h.
