I used to drive a Cat electric forklift in a previous job a few years back. It had a bit of poke considering it was moving circa 5 tons of counterweight around! Admittedly it was probably down to the extremely short gearing. It would max out at an indicated 18mph on the digital speedometer. That feels bloody fast when you have zero suspension, solid tyres and rear wheel steering though. bunglebus and paulplom 2 Link to comment Share on other sites More sharing options...
Tayne Posted May 29, 2020 Share Posted May 29, 2020 There’s a chap on YaTube! called Damien McGuire who ran a DC forklift motor in his e39 5 series for four years. The OpenInverter and DIYElectricCar forums are worth a look, there’s a lot of very useable hardware coming out of broken hybrids at the moment.

Aye, the thought did occur to me that Kiltox might be able to source some better batteries from an old Prius or suchlike. Either way, Kiltox, you're braver than me.

I think starting with an electric car is probably easier than converting (no ECU / can bus shenanigans required) but I'm not sure the MegaCity is the best base.

Kiltox Posted June 4, 2020 Author Share Posted June 4, 2020 Started having a look at this today, short on time/energy at the moment Strip down went well.... Getting the seats out was much easier than expected but I think that’s because they’ve been out recently. Tested all the battery voltages and they seem to be healthy enough - not sure we do have a dead one after all. Restored the charging circuitry to the default (fucked) Aixam charger which revived the clocks. Going to send the charger to @cobblers to see if he can work his magic on it, I think! Surprised to see it had new batteries in 2015 at a cost of £1200! Mrs6C, loserone, Stevebrookman and 10 others 13 Link to comment Share on other sites More sharing options...

Still, if it wasn’t for @strangeangel’s “where the fuck is the boot release on an Aixam” thread on here, I’d still be looking for it! Link to comment Share on other sites More sharing options...

320touring Posted June 4, 2020 Share Posted June 4, 2020 They'll be deep cycle batteries (like leisure batteries for a caravan). Designed to be drained much lower than normal car batteries. £83 a battery isn't too steep for them Link to comment Share on other sites More sharing options...

Tayne Posted June 5, 2020 Share Posted June 5, 2020 The charger in the car converts AC to DC and splits it’s output to all the batteries. I didn’t see any BMS (battery management system) kit on the cells so I’d like to think there’s some BMS functionality in the charger. However the car is a bit shit so who knows.

It is, but the 230v goes straight to the charger unit via a mains cable that runs from the back of the car to the front - there’s no electronics in the charging connector or the cable from car to wall. Any battery balancing etc is therefore done by the charger under the bonnet which is what is suspect, so without fixing it or replacing it, you’re back at square one.

Kiltox Posted August 17, 2020 Author Share Posted August 17, 2020 Right. I’ve massively neglected pretty much everything for the past few months however today I have dispatched a shipment of fail to @cobblers in the hope that the Aixam battery charger unit can be resurrected.

Unless the charger had taps to each battery then it's unlikely. Given these are lead acids, balancing will be done by float charging. Basically over charging the charged cells until the under charged cells fully charge. If the charge current level isn't excessive, the gasses will recombine and not vent.

SiC Posted August 17, 2020 Share Posted August 17, 2020 Looks like the pack is wired for 48v as 3 batteries in parallel and 4 lots of them in series. So probably a series wound motor, pretty much out of a forklift? Link to comment Share on other sites More sharing options...
