Voltron, the Electric RG!

Thinking about the ignition wiring... The off-ACC-on switch may or may not keep the ACC circuit on. Not that it matters for pre-charging the caps, because they will hold their charge for as long as it takes to break the precharge circuit and complete the contactor circuit. But still, I'm wondering i...

Katherine's ebike

No, it would need to be unplugged every time it's idle. I suspect that the 100 ohm resistor was too low for this application. Even on my electric motorbike it's a 2000 ohm resistor. Might need to pick up an alternative at Jaycar...

Katherine's ebike

Hi all! Well the House of Kat and Chris is now home to another electric vehicle. Kat has been riding 11 km to work and 11 km home most days on her pushbike, and while it's not too bad, on a day like yesterday when it's 39'C it's not much fun. So we ordered an e-bike kit from cell_man at emissionsfre...

I'm with Richo. Go for those NanoTech 90 C LiPos. You should be able to fit 10 kWh on the bike somehow.

Using an EV to power things.

But once it works, you can drive up to a public outlet, charge the car, drive home and run the house. Repeat until you get arrested for stealing electricity Image

DC loads...

Yeah, I normally push old stuff out when I learn new stuff :) I measured the resistance of the kettle and it was 25 ohms. At 106 V that gives a current of 4.24 amps. It might have been higher at first, but I wasn't paying too much attention. Not that it matters now, the Cycle Analyst screen won't di...

DC loads...

Hi all, I was testing my cycle analyst on the weekend to ensure that it's working properly. My pack voltage was 106 V, so I put a 2400 Watt, 240 Volt AC kettle on as a load. The CA read a 5.8 A draw. Now, 5.8 A x 106 V equals about 615 W. Hmmmm. Why the difference? I would have thought that at less ...

Questions on Elcon/TC chargers

Hmm, thanks for the insight Coulomb. I know there are different algorithms available, but the whole thing is a sealed unit, so I'm not sure how you would change it. There is no serial port either. How do these chargers work anyway? Surely if the maximum output is X volts, then the pack, connected in...

Questions on Elcon/TC chargers

Hi Nancy, I am using an interim charger purchased through ev-power. It is the 120 V, 10 amp 1.5 kW version. My pack voltage is 105.6 nominal (32 cells). When it states 120 V, does that mean it is used to charge a 120 V nominal battery pack? That is, 36 times 3.3 V? Because it's output voltage is cle...

Hi all, It was a slow Sunday for progress, but I did manage to set everything up for charging. Made up some bus-bar connections and wired them all in series, plugged in all of the BMS leads and set up the master control unit. My charge leads are good, with an Anderson clip at one end. I soldered the...

Voltron, the Electric RG!

At this stage I'm inclined to set the regen to zero. If just cracking the throttle mid-turn caused regen, I don't want a bar of it! About the controller. It does not divvy up the power - it just delivers power to the motor. Since the motors are fixed at the shaft, overpowering one will simply cause ...

It is the KDB12121 or some bloody thing. It has regen and is good for 1200 A. I don't think they make this particular model any more.

This is the replacement, again, with two motor terminals:

The weight of the chassis was 60 kg (forks with oil, tyres, frame, brakes, fairings and chain). The batteries are almost 65 kg. The motors are about 23 kg. The controller and wires etc make up about 7 kg. So yeah, this combined with the fact that much more weight is located over the front wheel make...

The two bolts on the controller that look really close together are the motor cables. Since both motors are in parallel, they can touch and it makes no difference. But yes, it's frigging tight.
