Reality check on motor/battery/donor combo please!

Thanks for the comments. I plan to use an Impulse 9 rather than the L/X-91. The general indications above make me think I should not loose any efficiency so long as I don't get heavy footed. I have wondered if it is possible to have some form of current limit between the batteries and the controller...

Heater for a cold climate

Me again, replying again to my own post. Having decided that 800W or so should probably be sufficient I was still a little uneasy about sending 144V DC into a hot confined space next to my feet. A fan failure and a meltdown could be nasty! Then I noticed there are a lot of 200W car heaters on ebay a...

Loaner tools for AEVA

On behalf of the newly formed ACT branch, and one who is just starting pulling stuff out of the donor car, thank you very much!
Peter.

Reality check on motor/battery/donor combo please!

Thanks for the feedback. I'll be interested to hear how it goes and may get in touch if I run into anything tricky as I dismantle the petrol-associated stuff. I had planned to not keep the clutch and removed the clutch pedal today. There seemed to be a fair consensus that one can do without it. Sinc...

Heater for a cold climate

Hi, I started this thread with a question but can now contribute with some experimental results! I got a variac set to 144V and plugged in a domestic 2400W electric blower heater. The fan didn't spin very vigourously but the flow was adequate. More importantly the air blowing out was encouragingly h...

In-car 10 amp charger for opportunity charging?

Hi, Looking at chargers, the Zivan NG3 seems suitable being light and small to fit in my car (just starting the conversion). I am aware of at least one other option to consider but it also requires a 15 Amp socket. If I want to top up while out it would be a bit embarrassing to melt someone's 10 Amp...

Reality check on motor/battery/donor combo please!

Hi, I am converting a Charade. I have just started pulling bits out and have not yet made any major purchases. I thought I had decided on the Impulse 9 motor since it should certainly give plenty of performance in a car starting (and probably finishing) with a weight of about 800Kg. I don't want to ...

Heater for a cold climate

I just looked at a few of these. They all seem to be 12Vx14A. I think that is the limit of the fuse on the cigarette lighter socket. That makes only 168W which sounds a bit feeble for when it's midnight in Canberra, there is frost on the windscreen, and fingers are cold. Still doing it with 12V rath...

Heater for a cold climate

Hi, I notice that various people including kiwiEV have used the elements from domestic heaters with ceramic elements in their electric car conversions. In Canberra it is often in the range 0 to -5oC overnight in Winter. Decent defrosting and cabin warming are definitely required! Doing the sums, a r...

Regen for DC?

Nonetheless what would be wrong with this idea... A generator of some sort could be arranged to be driven by the motor shaft but only loaded when the brake pedal is touched. That way there is no attempt at perpetual motion. Instead, with feet off both pedals the car would coast. When you want to slo...

Capacitor banks

I have not done the sums with respect to EVs but have for hifi amplifier power supplies. There the idea is that capacitors, in parallel with one's source of DC, have a lower internal impedance than the rest of the supply might have and can be placed close to the circuit requiring a lot of current in...

Does controller interfere with radio?

Hi, and thanks for the answer. I am planning a DC motor in a Daihatsu charade and not yet decided on a controller. I had not noticed anything about shielded motor cables in my reading so far. Everything I have seen seemed to suggest just using really fat cable with chunky lugs crimped on well but no...

Does controller interfere with radio?

Hi (first posting), I am just about to take the plunge and get my donor vehicle. I think I have done just about enough research to get started. Meanwhile, one niggling doubt: somewhere I think I saw a comment that the switching of high current in the controller made a lot of radio frequency interfer...
