All of the parts and numbers are listed at this blog post: https://www.summet.com/blog/2017/01/11/curtis-1231c-replacement-power-board-components/ I believe I will be able to upgrade the diodes to 600V 75A with the DIOTEC 7506R. Don't go by the ratings advertised on the front of a data sheet. They are usually absolute maximums. The part would soon fail if used at these limits. Look *inside* the data sheet for the test conditions. For example, that "75 amp" diode says it has a 1.35v typical voltage drop at 75 amps. That's 75 x 1.35 = 101.25 watts of heat. Now look at the thermal resistance from junction to case. It is 0.8 deg.C/watt. Therefore, the junction temperature rises 0.8 deg.C for every watt of power dissipation. 0.8 x 101.25 = 81 deg.C. You don't want a semiconductor junction temperature to exceed 100 deg.C or its life will be very short. So the only way for the junction to be at 100 deg.C with an 81 deg.C junction-to-case difference is for the case to be at 19 deg.C. In other words, you'd have to *refrigerate* the Curtis internal heatsink for the diodes to survive that current. A few questions I have with upgrading the capacitors. Is having a higher capacitance (330 uF instead of the stock 220uF) better (or would I just suffer from more inrush problems)? Capacitance does not matter. What matters is the capacitor's ESR (as low as possible) and its voltage rating (at least 25% more than the maximum voltage you ever expect it to see). Electrolytic capacitors have the shortest life of any part in the controller. As capacitors age, their ESR goes up, and their voltage rating goes down. At some point, one or the other of these gets bad enough, and the capacitor fails. The third option is to just keep the stock caps which appear to be fine and save myself 100-150$ and a lot of soldering... Only do this if you have a way to test them to be *sure* they are still "up to "snuff". I'm also considering a 250 volt 110A MOSFET (IXTH110N25T) to get the MOSFET and capacitor max voltages both up to 250. There is also a marketing "ratings game" with MOSFET specs. You have to read the data sheet pretty closely to see what they can really do. It's hard to be sure what part is better just from the data sheet. Given the Curtis design, the on-resistance of the MOSFET is important. NOTE: I never plan on running this thing with more than my current 135 volt max battery pack, but I figure having a bit more than 65 volts of headroom might help keep things from blowing up in the future...

Happy to hear from anyone else that found an available diode or an external solution. Jay Summit found a Diotec diode that appears to be a correct replacement. See diotec.com and search for "tab mount" rectifiers. Their MR2406FR, DR3506FR, and DR7506FR appear to be drop-in replacements if you get the "R" reverse-lead option.

Although lots of folks here disagree with me, I've argued for years, I think with justification, that the term "hybrid" has been widely misused. Until Toyota introduced the Prius and Honda the Insight, "hybrid" was well understood by EV specialists and hobbyists. It was a vehicle with two or more separate motive energy sources. Usually they were and are liquid fuel and electricity, but human-electric hybrids also exist. By that definition, the Volt is a true hybrid. The other so-called "hybrids" you're talking about don't fit the original definition. The non-plug Toyota Prius isn't a true hybrid. All the energy that makes it go comes from that gasoline you pump into the tank. It's a gas car with an electric torque converter and an electric supercharger. I don't know what it should be called, but as far as I'm concerned, hybrid isn't the right word. However, the plug-in Prius IS a true hybrid, because it DOES use two separate energy sources. "Hybrid" is even further off the mark for Honda Insight and its ilk, which AFAIK are still gas cars with conventional transmissions and electric superchargers I recognize that language evolves to be stronger and more effective, but I think that applying "hybrid" to vehicles that aren't doesn't serve anyone. As for the term "Compliance Car," Roger nailed it. It's an EV produced solely to comply with minimum-EV-sales laws. It's all about the manufacturer's intent. Typically a Compliance Car will be sold only in states that have those laws, won't be advertised much, and won't be state of the art -- but those are symptoms, not the disease. IMO, Compliance Cars are a form of passive aggression. A forward thinking automaker sees EV mandates as an opportunity (or an excuse to the shareholders!) to design for the future. A backward one sees them as an odious chore to be dealt with as cheaply as possible, in the most customer- unfriendly way possible. If a Compliance Car can be designed (or forced) to fail in the market, so much the better, since that failure will support the manufacturer's pre- conceived anti-EV notions and arguments.

We tried to be EV or at least HEV drivers in late 2008, but NONE were available at that time in our state of Louisiana. A salesman at the local Ford dealership spent his time with us talking about how bad electric or hybrid cars were in the heat of the South. Obviously he was much more interested in selling an ICE vehicle than he was in selling what the customer wanted. I still think about converting my 1951 Chevy pickup (an 'Advanced Design') to electric but I do have range anxiety. A '51 Chevy is not very aerodynamic and I would need lots of batteries. We have put down the $1,000 deposit for a place in line, waiting for a Tesla Model 3. I trust Tesla more than any other car manufacturer to build a quality electric car. I believe that typical ICE companies, like GM, are manufacturing EVs because they are being forced to by ZEV mandates in places like California. In other words it is my opinion that the Bolt is a 'compliance car.' If the Bolt were not a compliance car they would be available in other states.

The distinction between whether a vehicle is electric or a plug-in hybrid has nothing to do with how much more or less pure electric range it has than other vehicles of the same configuration. The Volt, just as any of the other plug-in hybrids, has two fuel/energy sources: an electrical outlet and a gas pump. The name differentiation is *bad* as it confuses buyers into thinking that the Volt is something other than a plug-in hybrid when many people are already confused between the difference between a hybrid and an electric car. The only purpose it serves is to allow Chevy to pretend that the Volt is in a class of its own. The 2017 Prius Prime offers 25mi all-electric range vs the first generation Volt's 35mi, yet one is described as a plug-in hybrid while the other is an "extended range electric vehicle"? Many of us have (or have had) pure electric conversions with less than 25mi range, but they were (are!) still unquestionably EVs; is it helpful to anyone to invent a new vehicle class to differentiate shorter-range EVs from all other EVs? I certainly don't think so. > The Volt on the other hand is a 60 mile daily commuter EV to-and-from > which is as much as triple all the other ones and carries along a gas > engine if needed to extend the range on a day when a long trip comes up > that is unscheduled. > > Big difference. Big difference between a Volt and an electric car, indeed! My sister was quite disappointed to find that her first generation Volt would *not* allow her to make her short commute on battery power alone in winter, despite the car being garaged each night. Very unlike an EV, this vehicle insists upon running the ICE for much or all of her commute in cold weather despite the battery being fully charged and having more than enough range the trip in pure electric mode. IT is NOT an electric vehicle with an on-board range-extender (that one can choose to use or not), which is what one might reasonably expect based on the 'extended range electric vehicle' classification; it is a plug-in hybrid that happens to have the greatest all-electric range of the present offerings. I like the Volt, but don't see its greater range justifying invention of a new vehicle classification (with it as the sole member) any more than it would make sense to invent new vehicle classes for the EV with the longest range or the ICE vehicle with the longest range to allow their manufacturers to pretend that their vehicle is in a different class from all others.

Sorry for your bother... But there is a huge difference and the name differentiation is good. Since the Chevy Volt has the longest EV range of every one of the 15 plug-in hybrids now on the market it diserves a very definite distinctive nomenclature. All the other plug-in hybrids are basically hybrids with a slightly bigger battery and on the order of only a single local errand for EV mileage.

Regardless of what the uninformed masses might ~think~ such a term means, I would hope that we, in a forum such, as this would do our part to use the term properly and do our part to educate others in the correct meaning and usage of the term, just as we do with terms such as EV, BEV, PHEV, HEV, etc. Just as it bothers me to no end each time I see the Chevy Volt referred to as an 'extended range EV' while the plug-in Prius remains (correctly!) classified as a hybrid, it bothers me to see people in this forum improperly use the term 'compliance car' as a derogatory reference to any OEM EV offering that, in their opinion, represents something less than the best that the OEM is (or, in their opinion, should be) capable of offering.

Re: [EVDL] What is a compliance car? : ... Bolt named top car ...
Roger's response is correct as there is a definition of the term.
But I am talking about what humans do, not an academic (funkandwagnalls.com)
definition [
http://www.urbandictionary.com/define.php?term=Funk%20and%20Wagnall
]. Humans take a word or phrase and change its use over time (as in
urbandictionary.com or a slang use has changed what the term now means).
So, the less informed as Roger (people in the public, EVnoobs), would hear
the phrase 'compliance car' without initially & truly understanding what it
means, & just surmise (pick-up) that it is a not a positive thing. I would
hope that those EVnoobs would later do the diligence (the proper research
work to know what the actual definition of 'compliance car' is as well as
Roger knows).
But sadly, today's public is beyond skimming (meaning, they short-cut their
way through life), without actually reading throughly, or doing proper
digging to know what words, phrases, terms, etc. actually are.
Though I am not focusing on dissing this type of person, I am acknowledging
that they have become a larger and larger percentage of the population that
EVangels have to work at communicating with when out talking to the public.
This thread has already had some responses of what member's 'think' or
'feel' a 'compliance car' is (or is not). This is what I was seeking, as it
would likely reflect what EVangels will encounter out in the wild.
This is not to say that a 'compliance car' is a totally bad thing to drive.
My focus is ensuring that people know the strengths and weaknesses of what
production EVs are available, whether they actually are a 'compliance car'
(as Roger reminded us), or are being labeled a 'compliance car' by people's
ever-evolving definitions.
As posted, a perfectly viable EV that Roger would not define as a
'compliance car', might be considered by many as a 'compliance car' because
it does not have (normal) "ads on TV", etc. like the way ice cars have.
ice-car advertising and column reviews are what we consciously or
subconsciously considered as 'normal'. Any item trying to be sold without
using that method, will be considered less or unworthy of consideration,
etc.
If anyone has not posted their view on what they 'think' or 'feel' a
'compliance car' is, I ask that you do, for the record. As our evdl Sys
Admin recently pointed out, my EVLN work is archived in the hopes that it
serves many purposes, one of which is an archived record for future
researchers to glean. The same goes for what members post on this topic.
This is a point in time that is unique (not 2010, and not the future, etc.).
My thanks to all that participated :-)

Re: [EVDL] What is a compliance car? : ... Bolt named top car ...
Quebec becomes the first Canadian province and 11th North American market, after 10 US states, to adopt a ZEV mandate.The law is modelled after the one in California, where the Zero Emission Vehicle (ZEV) Mandate originated and where it has been the most efficient in accelerating the growth of electric vehicles.. Quebec’s ZEV mandate works the same way. It forces automakers to sell electric vehicles for credits in order to compensate for their gas-powered vehicle sales or to buy the credits from other automakers who have a surplus, like Tesla since it only sells EVs.

What was a compliance car in > the 1990's and 2000's, is much different than today. I disagree. I think that 'compliance' is a well-defined and unambiguous term that refers specifically to *complying* with a ZEV mandate such as CARB's to the minimum extent possible. A compliance car would therefore only be offered where required to *comply* with such a mandate, and even in these areas might or might not be available for purchase. Any vehicle offered for sale where not *required* to satisfy some regulation or mandate *cannot* be considered to be a compliance car, regardless of how competitive or desirable any individual might consider it relative to other available vehicles. I think attempts to redefine or broaden the definition of the term to include vehicles that are offered for sale even where not required to comply with such mandates simply because an individual disagrees with the manufacturer's design choices or such is simply a case of those people who insist upon seeing the glass as half empty rather than half full and need to find something to complain about even as OEM EVs [slowly] become more readily available.

Re: [EVDL] Curtis 1231c - 18 or 19 power mosfets?

The logic board is essentially the same as the 1231B. The 1221C and 1231C logic boards had a number of part value changes. The 1231B and 1231C had a different power board, and a bigger case. Regarding parts, I found a tube of IXTH50N20 on ebay to do my rebuild I have been unable to find a source for the diodes. I am planning on replacing the mosfets removing the damaged diodes. If you replace any MOSFET or diode, you should replace *all* of them. Since they are directly in parallel, they all need to have the same on-state voltage drop. Otherwise, whichever one is lower will "hog" the current, run hotter, and burn up sooner. Some one mentioned mounting the diodes externally not sure if that would provide the same protection. That's a bad idea. You need the MOSFET-diode-capacitor loop to be as short as possible, or voltage spikes get worse. Happy to hear from anyone else that found an available diode or an external solution. Jay Summit found a Diotec diode that appears to be a correct replacement. See diotec.com and search for "tab mount" rectifiers. Their MR2406FR, DR3506FR, and DR7506FR appear to be drop-in replacements if you get the "R" reverse-lead option. -- Teaching children to program goes against the grain of modern education.

What was a compliance car in > the 1990's and 2000's, is much different than today. I disagree. I think that 'compliance' is a well-defined and unambiguous term that refers specifically to *complying* with a ZEV mandate such as CARB's to the minimum extent possible. A compliance car would therefore only be offered where required to *comply* with such a mandate, and even in these areas might or might not be available for purchase. Any vehicle offered for sale where not *required* to satisfy some regulation or mandate *cannot* be considered to be a compliance car, regardless of how competitive or desirable any individual might consider it relative to other available vehicles. I think attempts to redefine or broaden the definition of the term to include vehicles that are offered for sale even where not required to comply with such mandates simply because an individual disagrees with the manufacturer's design choices or such is simply a case of those people who insist upon seeing the glass as half empty rather than half full and need to find something to complain about even as OEM EVs [slowly] become more readily available.

Re: [EVDL] Curtis 1231c - 18 or 19 power mosfets?
I have mine apart presently, parts arrived but I have not had time to tackle it. http://divemaster.ca/kubvans/EV1/Controller%20mosfets%20sm.jpg I have been using this drawing, http://divemaster.ca/kubvans/EV1/curtis_1221b_schematic.pdf the output is basically the same as my 1231 hope it helps. The first device in the chain of mosfets is also different as confirmed in other posts. Mine has an MTW20N20. Regarding parts, I found a tube of IXTH50N20 on ebay to do my rebuild I have been unable to find a source for the diodes. I am planning on replacing the mosfets removing the damaged diodes. Then testing it under light load maybe just a resistor load and scope to see if it is working then make a serious search for a compatible diodes. Some one mentioned mounting the diodes externally not sure if that would provide the same protection. Happy to hear from anyone else that found an available diode or an external solution. I found a replacement controller so am not in a hurry to fix it but would like to have a spare or for a future project. Note : re-posted to meet Forum requirements regarding attachments.

Re: [EVDL] What is a compliance car? : ... Bolt named top car ...
? So, how do you define 'compliance car' ? I bought a 2014 Volt because I wanted at least a partial EV, Tesla only other option and unsure if I would survive surgery and i regularly do 1,100 mile trips (where I could use a supercharger) 2014 Volt = 16kWh battery, 66% usable (~10.3kWh)3kW max charge rate newer Volts ~18kWh battery3kW max rate charge Volt is on ragged edge of compliance car.teeny tiny upgrade, not even faster charging (why bother, teeny tiny battery) -- next part -- An HTML attachment was scrubbed...

My 17 years old car in salt spray and no vax ever, still no rust..)

They did not even bother to show up at the EV-fair show in Gothenburg and Stockholm recently, plenty of Teslas, BMW, KISaSoul, Nissan, and so on, most other producers did show up, even very strange things like Toyota Mirai ..that cant be charged at home at all... and have very very crapy primary energy / mile consumption. (things that they refused to answer questions about. "Toyuta dont know how much energy/km it consumes", -yea.. sure! :-) And they have only 4 "gas-stations" in the whole country.. Still they got plenty media coverage anyway, So just imagine what the Amperae with its eu-"500" km range would have seen!
