Re: EV Motor Durability

To give you an idea of the inefficiencies of a DC motor, I ran the DC motor in my car at one point without load to wear in the brushes. 17 hours of running with no load used 15kWh of electricity. Extrapolate that out to 24 hour a day operation gives 21kWh required per day just to keep the motor spin...

Re: EV Motor Durability

A DC EV motor? Wire it for shunt mode (so you don't need a controller) and keep an eye on it to make sure it doesn't overheat. Should last for a long time. 120 horsepower (90kW) is a huge load. That's 39 10A outlets at full capacity. antiscab's 14kW motor would only do one sixth of that power. Do yo...

Re: Chinese DC-DC converter

So to be legal do I need to send it off to a lab for Australian certification , or just get the seller to certify it , or can I just test it with my DMM ? Can't test it with a DMM as it won't generate a high enough voltage. I think you'd need a megger? Electricians have them. I'd ask advice from so...

Re: 10 Amp charging

Thanks @4Springs. The light comes on all the time and doesn't change with any flexing of the input cable. However, the RCD test button doesn't do anything so I'm guessing the input is OK, but there's either a problem within the RCD relay or between it and the input cable within the box itself. Ah, ...

Re: Chinese DC-DC converter

OK thanks, where would I find the Australian requirements, other than NCOP14 ? I cant find anything in there about isolation where it mentions auxilliary ELV , obviosly when I turn the car off the DC-DC converter will be isolated by a seperate relay , or am I missing something. ?

Re: Chinese DC-DC converter

Size: 30*19*15mm - seems a tad small! The photo looks more like 100mm long which would be more like it.
Max output current 32A. You'd need two I think, but still good for the price.

Re: 10 Amp charging

Try flexing the cord too while plugged in. Watch the light - if there is a wire broken inside the cord it might come on when you flex it. If it is a broken cord then you can replace the cord and plug yourself for a few dollars. No need for an electrician for a plug-in appliance (as long as you pull ...

Re: Outlander PHEV Range Extender?

Hi Rob, Maybe off topic, but my friend has asked about charging his 2017 PHEV after only a 20k run. Is it critical to re-charge after partial discharge, or can it be left and allow the motor to kick in to re-charge? The vehicle is generally used every second or third day and does not stand partiall...

Re: advice?

What I want to get out of it is about 130km/h, and decent acceleration with a range of about 160km. (Launceston and back from here) I figure some bright spark will put a charging station in Campbeltown soon enough. And I want it to be able to carry a decent load, at least fill the seats in a five s...

Re: advice?

Is it worth it, (we are off grid solar)? This is a difficult question - I think we need more info! It will use roughly 20kWh per 100km. Being off-grid you might want to carefully control when and how quickly you charge it? If so this will be more configurable with a home-made conversion than an off...

Asking on behalf of someone looking at a secondhand iMiEV - how can you tell if it is any good?

Re: Battery Suppliers

We have a controller that has a range of 92 - 170VDC and 600A. I guess about 150V would be best, since that is fairly common.
At the moment we can only afford about 160kg of battery, so lead won't go far. And there seems to be a willingness to find the money for lithium.

Definitely wrap closed cell foam around the pipes - that stuff can make a world of difference. Would it be easier to wrap a heating element around the pipe just before the heat exchanger?
