|Additional Features||I’m planning battery heating carpets under batteries and solid isolation considering Swedish winters, similar to Canadian. All lamps are LED including day running light. I have new Pioneer MP3 with 4x50W mos-fet amplifier and speakers but no time to install it. |
|Well folks, this is a fully functional car, working as a clock. Total cost: 3900EUR with a lot of sec-hand parts and fully refurbished brakes, underneath, new tires, and so on. The car itself is 1990 but looking good considering age, just a little bit of rust on doors lower edges. Driving this car is a feeling for itself. No noise, no smell, just a joy knowing that it´s ecologically correct makes me feel proud.|
Every story has a funny side. The CAR IS NOT LEGAL!!!
I am not sure how but I found myself in a very strange situation. During technical examination they said that car does not fulfill EU laws as the brakes have vacuum from electric pump from VW, not from original Fiat ICE. At the same time they are forcing me to do complete Electro-magnetic compatibility test although every single component is tested itself. Strange things happen… Every single detail on the car is coming from other vehicle or manufacturer that have a standardization certificate but it does not help… Now, I´m waiting to see how the transportation council is going to react on my complain. So folks, be aware that the forces that control OIL and Taxes are powerful enough to make our life very-very hard.
Update, 16 June 09:
Finally, the car is LEGAL. Transportation council has judged that EMC testing is not necessary, and that brakes should work fine with electric vacuum. Thanks to wise people at the council, I appreciate a lot their decision. I can finaly start planning for the next project, next goal to found LiFepo4 and BMS before winter.
Update october 2009:
Dyno-europe lead acid battery pack just died after 60 cycles, I got new one due to guarantee after 2 months negotiation with suplier. Then I sold those batteries. I got promotional price to Lifepo4 battery pack with 128V 100Ah with BMS charger from China Hi-power battery. 128V 100Ah battery pack purchased with BMS charger, preliminary delivery sometimes in December.
Update February 2010
After 4 months of waiting, lithium cells have arrived. It took some time for testing and figuring where to place them... Final solution, all together wrapped in cell-plastic isolation with heating carpet and thermostat in trunk. Good old approach having them all in one place feels great, hope to start driving soon. Wish me luck!
Update March 2010
2 weeks of driving with new battery. Wow, what a difference between these and lead-acids. Much more power, very small peukerts effect, voltage is stable and pending from 3,4V to 3V as lowest I get after 60km of driving. But to get there it took me almost 20 hours of looking close to cell meters while balancing those overcharged cells that tend to go as high as 4,2V once or twice during those first 4 or 5 charges. Having shunts doesn’t help at all due to fact that charger is continuing to push 15A no matter. So, 3 pcs of 60W halogen lamps did the job of discharging those “wild ones” and pulling them back to the same level of 3,6V where other cells where. Today after 25km trip from job back home it took almost 3 hours of recharging. Energy needed to recharge was 4,2kWh from wall outlet meaning 168Wh/km and due to the fact that Zivan NG3 has 85% efficiency, Wh/km of 143 is not so bad. Conclusion: It was worth waiting and choosing these cells as they perform superb. They are very stable, superior power, good balancing after 20 cycles: H:3,420V L:3,399V and DV:0,021V, not too bad I think. If someone is still reading this and has a question about cells do not hesitate just ask if you are wondering something.
Update April 2010
Spring is here and air temperature is rising. Last week with 15’C energy needed for every day trip to and from work is 130Wh/km. looks promising having a total of 80km or 50 mils for possible range. Batteries are performing brilliant, very stable, no voltage sags, and no need for extra balancing. When fully charged DV = 20mA, and 60% discharged DV = 8mA, much better then I even dreamed. If judging after 2 months driving like this is going to work well. Petrol savings last 2 months are 250EUR; tax reduction is 25EUR and insurance reduction 50EUR. Lithium battery is going to repay itself in 24 months… 2 down, 22 to go to positive zero!
Update October 2010
Weather is getting cold. Swedish winter is coming. Whole summer car was working just fine, no problems at all. Energy needed for daily trips 45-60km was 115-125Wh/km depending on speed and type of traffic, counted with all the losses, directly from 240V outlet. Batteries are performing well, no problem at all, only problem is I used to have problem with lead-acid batteries and still looking at cells and observing…
Next step is preparing for winter, buying winter tyres and preparing automatic heating system. ((One annoying thing is all fuel-car racers trying to prove something to me on the road, mostly that they are faster. OK, I now it as I was aiming for distance and money savings with this car. My future plans are small retro car with explosive attitude and racing capability))
Update January 2011
Winter and snow driving and temperatures –10 to –26 ’C. Car is running smoothly, no problem at all. Cabin heater from outlet is on during charge and produces nice temperature when enters car for driving. Batteries are performing WoW, no problems at all. Just the fact that voltage is 100mV/cell lower compared with summertime. Capacity is almost the same, I push it to 75% a couple of times and the cells still run 3V with 100A permanent load. Charging for new project… gone retro!
Fiat is now SOLD.
Thanks for your support and interest.
