I don't recall it being *quite* that bad. IIRC, you could usually get 40-50 miles of range with only 1/3 of the vehicle weight in lead. :-\ Years ago, Bob Rice wrote here about the Renault-based EFP Mars II that he worked on in the late 1960s. The EV weighed about 4200lb all up, and the battery 1900lb. That's ~45%. Bob said its real-world range was 95 miles at highway speeds. But I agree with your main point. Once the Nissan Leaf and Tesla S were established in the market, the days of EV conversions were numbered. I can see the effect in the EV list archive, with gradually declining numbers of monthly posts starting in mid-2012. That said, I think there might still some valid reasons to convert. - As a technical challenge - To have an EV you can work on and improve yourself - To clean up a beloved classic and make it (one hopes) more reliable - To get a type or style of EV that no manufacturer currently offers, at least where you live > I've been predicting for years that unmolested examples of those early > clik-clak DC and lead-acid conversions are the future EV collector's > items. They are disappearing quickly. I think that that's more likely with the early modern production EVs. I've heard of really clean Citicars going for 5 figures, for example. But you might be right, and some conversions might appeal to collectors someday. I'm no expert, so don't take that as investment advice - or any other kind, for that matter.

[EVDL] Not a conversion, was: '91 BMW 318i conversion to electric
Quite a few years ago, I happened across the Nevco Gizmo EV. Constructed from the ground up in the USA using locally sourced parts (mostly), it was certainly a unique vehicle. I felt I had a great deal on the purchase and sunk a few more simoleans into it, replacing 560 pounds of VRSLA with 200 pounds of LiFePO4, increasing the voltage from 48 nominal to 66 nominal, 69 off the charger. With the weight reduction and voltage increase, top speed went from 35 to 52 on level ground and range was boosted from 15/25 at 50% consumption to 75 miles at 80% consumption. The DC/DC converter didn't like the 69 volts, but a day's delay off the charger, or a few minutes with the key on and it was happy again. One aspect of the vehicle was the side stick steering, which people felt would be a skid-steer environment, but the reality was that it was ordinary motorcycle feel. Another trip for the alleged mind was the hinge at the top front access. It's astonishing how many people associated that with the Isetta (side opening, not top!) but that's how the world turns. I believe only 36 were produced and my #32 has quite a few of the "upgrades." This included a belt drive in place of a chain (so much quieter) as well as a set of F-16 grips for throttle, lights, horn, turn signals. My personal upgrades were the batteries, of course, but a CycleAnalyst to allow me to keep track of the pack health and depletion, along with forced air cooling on the motor, and a gear reduction to increase rpm for yet additional cooling. I was able to manage four miles per kilowatt hour, which in retrospect isn't particularly efficient, considering that I can get four and a half miles per kilowatt hour from our 2013 Rav4EV. Except for the go-cart-stiff bone-breaking suspension, it was more fun than the Rav4EV. Prior to the gear reduction and forced cooling, the too-low rpm took its toll on the brushes and fried them. Pretty inexpensive to replace the motor from NY state, although it weighs 70 pounds. A video can be found on the YouTube showing the vehicle without the side curtains or vinyl windows, which were later installed. | | | | | | | | | | | Gizmo Goes (trip two) | | | It's not a conversion, but it certainly was a project. Unfortunately my health prevents me from working on it for possibly as many as ten years and the pack is kaput, the side curtains and windows are mildewed beyond belief. Before relegated to the back yard, the motor was problematic, with a cogging feel unrelated to "normal" expectations. I have a rebuilt motor in the box ready for impossible-for-me installation, along with the requirement of replacing the pack, of course. It's a sepex motor, purported to be more efficient. The controller also supports regen, which was never implemented while in my hands, nor the previous owner's. Brembo disk brakes for the front and a rather unusual rear brake primarily for parking/locking out movement. In a tadpole/reverse trike, one does not wish to lock the lightly loaded rear wheel, unless swapping ends is on the menu. I never tried to spin out, other than on a sandy patch, as I didn't want to subject myself to replacing a hundred dollar herringbone drive belt (back then. How much now?). If anyone wishes to take on a rebuild project, drop me a line and I'll be happy to send Barn Find grade photos. No offer considered too absurd. Three ramp trailer included, but probably needs a bearing repack after sitting for ten years! -- next part -- An HTML attachment was scrubbed...

t-cars/586/best-electric-vans Also small, medium, and large vans from Renault. Theyve just updated their Kangoo and Master E-Tech vans. The Master has a 3600 lb payload, and a WLTP range of 285 miles with the 87 kWh battery. Most of the EU brands, such as Citroen and Renault, dont have a US presence that I know of. However, the Ford E-Transit and the VW ID Buzz Cargo are available there, right? Or is it mostly pickups rather than vans in the US? (Tradespeople here usually drive vans, seldom pickups.)

Re: [EVDL] '91 BMW 318i conversion to electric
Howdy Folks It's been years since I posted here (ever since discussions of drag racing were banned), but I do still read the EVDL on occasion and credit the folks here with providing an initial crash course for me on EV technology. The conversion issue made me want to chime in. The days of inexpensive lead-acid and DC motor conversions are long gone. I've been around this industry for 25 years. It's a completely different animal now. There were no factory EVs available then and folks were forced to accept extremely limited range (good luck telling someone they can only go 50 miles max on a charge now and that 50% of vehicle weight in lead batteries is required to do it). IMHO, If you want to convert a modern car, your best bet by far is just to get a factory made EV. You could buy a handful of Nissan Leafs by the time you pay someone to do a modern vehicle conversion with decent power and range. Just getting the onboard computerized systems of a modern vehicle to play nice with a completely foreign drivetrain is a herculean task all by itself. Plus you are pretty much tied to the person or shop doing the conversion for maintenance or repair issues into the foreseeable future. In fact, there is little that's inexpensive or easy about it now compared to then. The target market for conversions now is classic vehicles from back in the days of ignition points and carburetors. Like a collector car that a person would keep for decades. You need substantial bank to even consider having a nice conversion done for you. A $100K+ price tag is not unusual, especially using brand new components and including the cost of the donor vehicle. For that you could likely find a Rivian, Lucid, or Tesla Plaid. Especially on the used market. One positive aspect is that used EV components are now available from wrecked EVs. We didn't have any of that back in the day. It's hard to beat a Tesla rear drive setup. It's nice to see folks still involved here that were posting on the EVDL 25 years ago when I first got into EVs. I must say that some of those same folks are recommending books on EV conversion that are like 25 years out of date. I personally don't see this as being helpful to those new to EVs that want to learn how modern ones operate or how to convert one, especially with an abundance of free and modern info available on YouTube and other online sources. Wanna learn how to set up an Orion BMS? There are videos on that. Please remember that the days of 96 volt VW Rabbit lead slugs are long gone. Though I've been predicting for years that unmolested examples of those early clik-clak DC and lead-acid conversions are the future EV collector's items. They are disappearing quickly.
