Ok people I am about to sort of hijack my own thread. Since I blew my first charger I have had an idea as to how chargers may be made more reliable. I always dismiss this idea until I blow my next charger and the idea resurfaces. It appears to me, from my own experience and comments made by other pe...

Thanks guys I have tried the new smaller Elcon chargers, Neither worked. In a previous thread back in August 2017 I listed some of the problems I had with the new Elcons. i quote it here so you don't have to go hunting for it: "First problem is that the connectors are 4 pin, pin and socket connector...

Thanks coulomb The chargers I use are KPS (KingPan) but it is not because they are the cheapest I could find. They are half the size and half the weight of the Elcon chargers of the same wattage. Size and weight are both important factors when fitting components into a small Suzuki Swift. The KPS ch...

Thanks guys I am starting to understand.

Ok guys I think I understand. It is not simply volts times amps equals watts? There is more to it than that?

By power factor I assume you mean the inefficiency of the charger. The charger normally sends 85 to 90% of the power it receives into the battery bank.

My confusion is with the readings on the power meter itself before the power even gets to the charger.

Hi people, I have been charging with a new KPS 2000 charger which is fairly obviously a 2kw charger. 2kw divided by 240 volts means a roughly 8.33 amp draw. I then noticed my 10 amp extension lead was getting very hot. I bought a power meter and took some measurements. According to the power meter t...

Thanks coulomb when writing my post I suspected I was "out" by a factor of a coupla billion!

I can't be sure but I think, since converting to electric, my car has done 210 xenna nanometres?

Thanks T1 Terry and Richo

Your suggestions have given me a few things to explore! I think I might sit down, grab a glass of red and think through this a bit more.

Paul

Thanks T1 Terry. Good ideas!

I hadn't thought of air filters either so this morning I will be off to my local car spare parts place to see what they have.

Thanks again
Paul

Thanks guys

jonescg - yeah good ideas and I never even thought about dust getting in.

Richo - I assume the fan in your picture is something like the "Fan Blower, Scircoco Ace 76 Series 109BD12HA2(HC2)[HD2" available from Element14?

G'day people, As you may be aware my battles with chargers seem to be a never ending story! I have used both TC/Elcon chargers and KPES (Kingpan) chargers and have had both types fail at various stages. At present I have a 2kw (or is that kW? - I should have checked Weber's post before I started wri...

Thanks weber, my bad!

Thanks guys much appreciated! I have read your posts, and the references in the posts, and the references in the references in the posts, and obviously far greater minds than mine have grappled with the problem. brendon_m, your diahatsu and my suzuki swift would be similar weights and sizes I guess....

Thanks jonescg. When you say these are no load resting voltages - yes that is correct. When you say "that's pretty close" do you mean the cell voltages as per the table are pretty close to the SOC's I have determined or that the TBS Pro's SOC would be pretty close to the actual SOC? I am trying to d...

My question deals with estimating a battery bank’s State of Charge (SOC) from the voltage (OCV) of that bank. I understand that the difficulty lies with the relationship between SOC and voltage in lithium batteries being very non linear. Going back maybe 8 to 10 years this topic was discussed. At th...

Doesn't sound like "plug and play" coulomb?

Or is it something one would get used to quickly?

I have a 40 acre property 200kms west of Sydney. It is totally off grid. I have had PV panels and a 400watt wind turbine for over 10 years. acmotor's post above very accurately reflects my experience with PV and the turbine. The PV works less well in winter than in summer (no surprise there!) Becaus...

I will investigate the TSM chargers with OzDIY. I have met Graeme before.

Maybe the only plus the Zivan might have is that they have a distributor not far from me.

Thanks
Paul

Having had a "gutfull" of chargers blowing I am investigating buying a Zivan NG3 charger. The firm I emailed in the USA advised me: "Paul, We have the 240VAC 144V 18A Zivan NG3 chargers in stock. They sell for $1029 USD plus shipping. They can be programmed for 140.4VDC output." I wasn't sure if the...

Thanks Richo

I will pass that info on to my brother.

Regards
Paul

Thanks Richo

The pictures you were after.

Sorry guys but it turns out I gave you a "bum steer"! Got my brother over to help with the charger problem. When I hooked up the light, the cleaner and the heater, through the car, NONE of them worked. (Unlike last time when they all worked except the charger). And of course the charger didn't work ...

Thanks very much Richo and Johny, I will get my electrician brother over to help me (or more correctly - me help him) with an "electrical diagnosis" during the week. I will show him your opinions. Of the three things I tested, the 10 watt lamp and the 2400 watt heater had earth pins. The 150watt cle...
