Re: Prelude conversion project - some questions
The beauty of this thing is that it talks to the TC charger and takes signals from the EVSE the car is plugged into. If the EVSE says it can offer 32 A at 240 V AC, then the widget tells the TC charger to up the power. If the EVSE is limited to 15 A, it will automatically turn the charge power down...

Re: DC Motors - Shunt?
I'd need to ask @zeva if it could handle regen from a DC shunt motor. Unfortunately not, the motor controllers I make are a "quarter bridge" design which can't support regen. As far as I know, Zillas and Curtises are the same story. I think Kelly do some half bridge controllers that can support reg...

[SOLD] Honda NSR150 electric motorbike, $2900
Bike is now sold! A few years back I converted my Honda NSR150 motorbike to electric. I hardly ever ride it and its license renewal is coming up, so I think it’s time to either sell or decommission it. It’s probably worth more sold as parts, but I’d rather see it go complete to someone who might en...

Questions on Elcon/TC chargers
Elcon (TC) Chargers are normally setup in the factory for your preferred voltage. I recently added CAN integration with TC Chargers to the ZEVA EVMS. As people have mentioned, it allows you to adjust the charger's target voltage and current parameters, and also allows the BMS to shut the charger do...

Ian Hooper's Honda NSR150 conversion
Range seems to vary a lot depending on speed. On the weekend I pottered about the suburbs at 50km/h and got 10.8km from 10% of the battery (equals 108km range)! But just now I did a 16km loop with half of it at 80km/h, and it used 31% (equals 52km range). I was probably more enthusiastic on the thro...

Ian Hooper's Honda NSR150 conversion
Well, after sitting in the corner of the workshop in pieces for more than a year, the electric NSR is back up and running again! I had planned to convert it to AC, but decided just to get it back together with the motor I had (Motenergy ME0709), and fix some of the old shortcomings. Its main problem...

Adverse Effects wrote: from there website
"Continuous current of 205 amps at voltages of 48-144V"
so it carnt even do what 1/4 of the AC35X2 can do
Continuous power and peak power are not the same thing.

Well, I only mentioned motor and controller for $5K. But how about a Motenergy ME1002 motor + ZEVA MC1000C controller .. leaving $1500 for those other things.
Edit: I'm actually not sure if that Motenergy is OK at 1000A - would probably have to run it by EV Works.

Daihatsu Charade EV project, advise please.
Sorry, I forgot to mention that it is my ultimate hope to get a travelling distance of at least 80km before recharging. This is how far the return journey is from my place to the Hobart CBD. It is a hilly drive and the hills are steep and long by Australian highway standards. There is hardly a leve...

Ian Hooper's Honda NSR150 conversion
Do you notice any of the high weight when riding the Honda? Can't say I notice much, but (a) it'd been over a year since I'd ridden the bike as a petrol burner before doing the conversion so didn't have a clear memory of it before and (b) I'm not much of a connoisseur of motorbike handling! That sa...

Ian Hooper's Honda NSR150 conversion
A question for others who've done motorbike conversions.. I've decided to use the bike as a testbed for AC motor controller development, so I've stripped out the DC gear and will be getting one of the Motenergy BLDCs to put in instead. Their brushless motors aren't as torquey as the DC one I had in ...

Hi all, I recently decided to use my NSR150 conversion as a testbed for AC controller development, so have stripped it down and have a few of the old parts for sale. The motor is a Motenergy ME1003, 72V DC, 11.5kW continuous, 23kW peak. Very torquey little motor which does a good job in a motorbike-...

Auxillary circuit help please!
Mostly reiterating what others have said - I would strongly recommend not having the DC/DC converter permanently connected to HV. Over the years I've heard about too many EVs with traction battery damage due to the DC/DC converter over-discharging them (and the BMS being unable to take action becaus...

Weber and Coulomb's MX-5
I’m with you on this, weber. Cell capacities will never match exactly so when charging a bottom balanced pack there’ll always be one cell running away to 4.2V+ while the others are still around 3.4V, and with a large number of cells it’s not possible for the charger to know the difference between th...

Well after about 12 months of 100% reliable service from the RX7, I had a couple of small problems crop up recently. Firstly one of my motor cradle vibration mounts broke. It was the one which would be under tension under heavy acceleration, i.e the motor cradle tries to lift itself off this one - f...

Sorry for the late reply, I temporarily wasn't getting email notifications from the forum for some reason.. Anyway the initial takeoff might feel relatively slow (compared to its performance once moving, or vs typical petrol bikes) because it's only a single gear ratio, i.e there's no gears for torq...

Hi Mike, It is running just fine so doesn't need to be considered a project, but the short range may be an issue for many people - myself included, living 20km from the city. In general I think it's good for conversions to go to people who like tinkering with things (that's part of the fun, and so t...

Ian Hooper's Honda NSR150 conversion
Yep, 57km would be 100% DoD - assuming the cells are still up to spec.
I didn't actually ride it until flat though, that figure is an extrapolation based on energy used over a 15km ride.

Ian Hooper's Honda NSR150 conversion
After some test-riding around the suburbs today (all 50-60km/h speed limits), I calculated the efficiency of the bike at around 47wh/km. With a 2703Wh battery pack, this comes out at a 57km range. More than I expected! If I were to carry the charger with me in a backpack, and had 90 minutes or more ...

Ian Hooper's Honda NSR150 conversion
Adding up all the main parts (motor, controller, batteries, BMS, EVMS, DC/DC, contactor, potbox, charger) gives a total figure of around $6K, so I guess it wouldn't be particularly cheap to replicate. Plus maybe 50 hours of labour of course! The NSR150s make a pretty economical donor though, $2K buy...
