Hi Chris - the problem with Blades is they are, well, not worth fixing unless you are a do-it-yourself sort of person. The cost to pay someone to do it is usually well more than they are worth when finished as they are all different and generally have unique problems built into them. (Plus paying others to work on a Blade will end up costing you more than the cost of buying a more reliable and parts-available older OEM EV). Additionally: even when going, Blades have far inferior range and EV tech than even an old iMiEV or Leaf. Old Leafs in particular are well supported by active communities, parts availability and dealers - plus Leafs themselves are well built and seem likely to last well into the future. If spending the sort of money to have someone work on a Blade - it is quite simply 'throwing good money after bad'. Even after fixing it, you will soon be up for the cost of a new battery pack anyway, as they are all getting quite old and were mostly all poorly battery managed.

I have heard of old Leafs needing new battery packs going for as low as $5k here. I'd suggest saving one of them from going to the tip!

Selling your Blade for parts to someone else with one who does their own work is a useful, non-wasteful end for it. They may even have a controller to fix it with! That in fact was my plan for an old long-range Blade I had here. My conversion van was reaching it's end-of-life, yet still had a good controller - and I had finally worked out how to match the controller to the AZD motor. Sadly Covid intervened and I had to sell the lot, plus my old Leaf, to stay afloat for 6 - 12 months of unemployment. (... ultimately including 6 months of being the full-time organiser of the many, many permutations of AEVA's 2020 EV Vision e-conference before it finally ran! ... but I digress ;-) )

Hope that helps - good luck with your decision making.

Kind regards

Repairing the bastards is a pain as you keep finding more build errors and problems waiting to happen as you fix something else. Having owned a Blade, and having been a converter of vehicles myself - I have no regrets about moving on from it to a cheap early Leaf. (And more recently: a Kona :-) )

Looks like I have a new project. Learn how to install and setup a controller. Thank you for your helpful advice. I was hoping to just pay someone to do it for me.
Sent you a PM yesterday re purchase of the Blade ..... Easier to get a non running EV out of NSW than out of WA .....

I tried to reply but the message appears in the outbox as sent with nothing showing in the sent messages.

That's normal. When Terry reads your message, it will move from outbox to sent messages. Confusing terminology, outbox should be called something like unread.

Thank you Chris, I have received and replied. Car carriers seem to think like freight mobs when it comes to moving lithium cells, whack a premium on top because the customer will pay it no matter what ...... It would be cheaper for me to drive up there in my truck and bring it home .... just don't have the time spare at the moment because the workshop is going crazy with jobs they all want before Easter .... as in a week before Easter and that's today ......

Thank you for the explanation. You just reminded me that I still have that charger you repaired for me.

If all goes to plan, I should be the proud new owner of an Electron V. I have reached the stage of actually finding and purchasing a Gypsy/Dolly trailer to tow behind my motorhome in the Sydney area, so the plan is to pick that up on the way through to collecting the Blade Electron. Then I can drag it around the country side via an RV get together in Taggerty Vic and then on to the workshop in Mannum. From there the silly questions will start in a different thread while I try to fix the existing controller/swap out the controller for a Wavesculptor 200 that I have here or swap out the motor and controller with a combination of what I have on hand .... or throw my hands in the air and it this one to the collection :roll:

Terry ...

I sympathise with you! I own an early Blade ... #4 I think ... and two more in storage without batteries ... They are certainly an acquired taste, but I think worth the effort. There is a chap in Newcastle names Jon Eggenhousen of Catavolt ... he would be a good bet to ask.

Cheers, Randall

Hi Randall, I have read a lot of your posts, were the ex Blade employees who lived around Castlemaine helpful as far as a knowledge base for the vehicles?
I'm looking at possibly increasing the pack voltage in an attempt to improve the range and the town gear speed, 40km/h isn't much use but 60km/h would be. The Tritium controller can handle up to 360v but no idea how much of the original blade stuff I'd have to replace. The specs for the DMOC say it can handle up to 400vdc with a max nom. of 336vdc so who knows. I'm guessing the controller is a 445 and not a 645, 53kW continuous would be great with a peak of 118kW but I doubt Blade were that generous :lol: 78kW peak and 38kW continuous are the more likely figures, and that would only be if you could keep it cool.
Should be an "interesting" project, if I have a win then maybe we can look at getting a few of the ones you have in mothballs back on the road with the EV smile that never seemed to be the norm from what I'm hearing from other Blade owners ;)

Hi Terry - yes, the Blades used a DMOC445, not a 645. However - don't bother trying to get an air cooled DMOC going. The only one I know that is still going well is an early one with a water cooled DMOC. For an air-cooled one: it is only a matter of time before it expires from heat exhaustion, and they cannot be repaired (as in even if you did succeed, something else would go not long after). DMOCs were the Achilles heel of Azure Dynamics. (Not helped by their placement in a dead air space in the Blades!)

The Wavesculptor using a higher voltage system goes well in them - however Tritium don't really provide much support for them any more.

Having repaired a number (too many!) Blades - I cannot emphasize enough that the best solution would be to rip all Blade installed motor, controller, BMS (and wiring) out and replace them with reliable parts that are readily available and wire it in a way that make sense. MUCH quicker, easier and ultimately cheaper - and results in an EV that is reliable to drive and can be fixed easily/quickly. I came to that conclusion after wasting WAY too much time trying to fault-find/diagnose/repair the existing systems as well as future proof the things from failing again. No two were ever wired the same, so any solutions I came up for one were of little use in the next.

Hope that helps.

Cheers
