[EVDL] Electron Automotive - Any experiences?
I have a friend that bought a Chevy Volt with front end damage. He replace the charger and charger connector and fixed the front end damage. The Chevy dealer says its throwing codes and 'no one will touch it'. Any recommendations? Any opinions about Electron Automotive?

Re: [EVDL] BMS/ leaf 60ah vs calb 60ah cells
How soon do you need it? We have been testing our BMS with leaf cells for 6 months and will be making it available soon. We have to finish our commitments to all of the people that signed up during our Beta program.

Re: [EVDL] EVLN: Open Source Street-Legal affordable long-range EV4the masses
The correlation between weight and efficiency is true below 45 mph in general. Above 45 mph aerodynamics starts being more important than weight. This is why the the heavy first generation Toyota prius has good highway MPG. In general the stop and go nature of travel below 45 mph overwhelms the greater efficiency. We used a hill between my house and shop to work on the aerodynamics of my car. After playing with cardboard and tape (then later vinyl) we increased the coast downhill speed by 15 mph and decreased my 1/8 mile time by 2/10 with the same trap speed. After this my 2000 pound Daytona-look-a-like went from around 350 wh/mile to 312 wh/mile driving 15 miles with 6 stop lights 4 stop signs and a large hill and no-regeneration in both directions. This was testing done for X-prize competition and was well measured. -Original Message- From: tomw via EV Sent: Monday, May 18, 2015 10:09 AM To: ev@lists.evdl.org Subject: Re: [EVDL] EVLN: Open Source Street-Legal affordable long-range EV4the masses The numbers you post for Tesla do not include charger losses, the 216 Wh/mile does. The 196 Wh/mile number should be compared. Either way 216 or 196 is far less energy/mile than a Tesla S uses, so more efficient at moving one human around, which is the typical occupancy. Maybe you are considering efficiency as energy/mile-weight. Then the Tesla would be 325/4750 lb = 0.068 to 375/4750 = 0.079 and my car would be 196/2260 = 0.087, so the Tesla moves a unit weight more efficiently than my car assuming those numbers represent the same 50% mix of highway and city driving. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Re-EVLN-Open-Source-Street-Legal-affordable-long-range-EV-4the-masses-tp4675590p4675619.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
Re: [EVDL] EVLN: Open Source Street-Legal affordable long-range EV4the masses
Generally speaking hub motors without shafts have a high unsprung weight and therefore have a rougher ride and a lot of stress on the motor. 24 kwh = 186 miles is more what I have problems with. 4 miles / kwh is great efficiency better than Tesla. The article did mention a max speed of 47 mph and rule of thumb at 45 mph aerodynamic forces are not significant so light weight vehicle does very well.

Lots of people have tried them, and few or none have succeeded. I'm sure I've missed some of the attempts, but this is one I recall that came close to success (though nowhere near production). They mention some handling problems but (I think) blame them on the somewhat high CG and narrow track. http://www.gaura.com/ev/luciole/index_e.html I have to confess that I've been smitten with this little gem since I first read of it in the late 1990s. It's impressive design work for college students, quite refined. What a pity it never even got close to production.

Re: [EVDL] charging two parallel packs in series
So I drew a really crude wiring diagram. http://goo.gl/kAj5wH Note that it is important the two packs are balanced within a few volts of each other after the series charging. Otherwise when you reconnect them in parallel they will arc across the connector and cross charge at a VERY HIGH AMPERAGE.

So when the key is out of the ignition, the controller and all other components are separated from the traction pack. I currently have a 120V system, with two strings in parallel, because I have a Curtis controller, which has a 144V max. I would, however, like to be able to charge faster with my PFC-30. So my question is, if I reconfigure the packs to be in series for charging, is there any problem, since both contactors will be open? Bill This could be done safely by leaving one pack ( pack A ) hooked up normally then using two Anderson connectors with your charger being the only thing connected to pack B's battery plus ,chargers neg will go to pack A's neg. Pack B will hook to pack A using a 175amp or bigger Anderson disconnect with pack A's pluses going to pack B's plus and A's neg to B's neg , this will be for driving and parallel charging . Pull the disconnect and plug in a Anderson jumper plug which will connect the A packs positive to the B packs negative and now your are charging in series. If you forget to switch back , no big deal you will just be running on pack A . A few ways to set up these Anderson's , I think the 175 amp Anderson would be big enough . I would have one on pack A and 2 and pack B ( one for series and one for parallel ) The series plug will have its b+ plug going to the B packs neg . shameless plug ,, we sell them but there not on the web site Steve Clunn Merging the best of the past with the best of the future. www.Greenshedconversions.com ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
Re: [EVDL] Open source software to control donor ICE's CPUs
So in general there is a huge liability issue from the OEM having to do with air bag time, fly-by-wire pedals etc. That said here is a project I saw at the Detroit Electric and Hybrid vehicle show http://www.pi-innovo.com/products/openecu When I talked with them they mentioned that they felt their hardware was a good fit for prototype vehicles and conversions.

The software is not served up by a drive, or kept on a flashable EEPROM, it is literally built into the silicon. snip It may require the original the development system to reprogram it. Or it can only be reprogrammed by replacing chips and boards - meaning it is very unlikely a DIYer will have the ability to hack it. That's exactly what chipping an ICE does. Replaces or reprograms a memory chip that contains data tables used by the car's software. It's a relatively safe process as you can only screw up the ICE's power profile and emissions output but can't cause the onboard computer (and maybe the car) to crash. The only viable open source solution would be to design a carputer that can read the car's original sensors, process the data, and use that to control the fuel injection, dash, door locks, etc. In the case of a Tesla, it might run the charger/inverter. Unfortunately, most EV-specific hardware probably has its own computer system that expects to send/receive proprietary and possibly encrypted data - making it close to impossible to control with a DIY computer unless MUCH help and documentation is provided by the OEM. Related story: A friend of mine converted a 2000-ish VW Jetta using a series DC motor. His biggest headache was the low oil pressure buzzer in the instrument cluster. Without a valid reading, the buzzer would go off constantly. He cooked up a circuit that would send a normal oil pressure reading, then proceeded to get startled at every stoplight! The dash computer would see the motor RPM drop to 0, notice the oil pressure was still normal... and set the buzzer off! Don't know if he ever managed to trick the instrument cluster into staying quiet. Didn't want to kill the buzzer as it is also used as a headlight reminder, seatbelt warning, etc. -Adrian ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
