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...

Thanks Richo

Just before I go have a bo-peep at the breaker I am confused. While the controller and the breaker are both part of the vehicle's wiring, they are not part of the charging circuit? Or are they? I don't understand.

Sorry - just showing my lack of knowledge!

Thanks
Paul

Hi people, After having two chargers blow simultaneously I bought two new KPES chargers. I installed one and hooked it up to the existing wiring in the car. The existing wiring consists of 3 prong connector under the petrol cap connected to an on-off switch connected to a 15amp circuit breaker conne...

Thanks jonescg

I'll go with 144v

Paul

Thanks Johny,

My pack is 140v at it's max but normally sits around 133v. So what your saying is that a 144v converter would have no trouble working off a 133v pack?

Thanks
Paul

Hi people, I have been continually adding cells to my EV to the point where my original 96v pack is now 140v (40 cells). Almost all components have been replaced to handle this increased voltage except for the 96v motor and the DC - DC converter. The converter is run in parallel with a solar panel t...

I just checked the evcomponents.com website where both the old TC models and the new HK models of the TC Chargers are both listed as having either the enable option or the CAN interface at the purchaser's discretion. I have always bought the enable option to keep things simple. I did purchase two of...

Thanks for the replies.

Looks like plenty of space and more fans is the go.

Paul

Thanks guys, your replies are appreciated. As far as I am aware both chargers are AC isolated and I have used this particular Chargepoint station with the current set up many times in the past. Excessive heat seems to be a common thread in some of your replies. I don't know how hot the chargers beco...

G'day people, I am not having much luck with chargers! About 18 months ago I decided to fit two chargers to my car. Use one by itself for 10 amp circuits, use the second one for 15 amp circuits and use both together when charging from 32 amp public charging stations. I bought 2 of the new small TC C...

Just a bit of a warning. About 3 years ago I purchased a flexible panel to put on the top of my EV to keep the aux battery topped up. Saves me having to use the DC-DC converter. The panel conked out after about 2 and a half years. When I purchased the panel I also researched methods of attaching it ...

Thanks Richo,

As a reconfirmation it is the panel you could measure with a DMM the PV output before charging then after the 20min when panel cuts out.

Yep Richo it was the panel.

I better start hunting around for a new one.

Thanks
Paul

Hi people, My investigations were somewhat interrupted by the flu so I didn't want to visit anyone and pass the flu along. Got to the solar shop today and they basically did the same checks I had already done. We opened the junction box at the base of the panel but couldn't see anything physically w...

Thanks Richo, I managed to check on the wiring yesterday. My multimeter showed that the controller's display was accurate. I then stripped some of the insulation off the two wires where they come out of the panel which eliminated, as possibilities, voltage drop or some sort of hot spot along the len...

Thanks Richo and Coulomb 1. Did it ever work? I think it did a year or two ago. The previous controller didn't give me an instantaneous figure for current charge or pv voltage. I replaced it because I assumed it must have become faulty at some stage. It wasn't until I recently bought a new controlle...

Thanks Richo, Can you actually charge your aux battery to 14V by any other method eg lab power supply? I have a 12v charger which charges the battery up to 13.5v at a rate of 1.7 amps. The battery then sits at 13.4v until I use the car again. The controller will go into what the manual calls "Bulk C...

Thanks coulomb, Is it 4 LiFePO₄ cells? Or some other lithium chemistry? The battery is marked as a Fusion Lithium battery V-LFP-12-26Ah so I assume it is LiFePo. How are you measuring the charge current? It sounds to me like a voltage drop issue. What wire do you have from the charger to the battery...

Hi people, I am having a bit of trouble charging my lithium auxiliary battery the way I think it should be charging. The system I have set up is that I have a 12v 90 watt flexible solar panel on the roof of my car. I also have the DC-DC 96v converter which has an on-off switch on the dash board. Bot...

I was just wondering if anyone who attended the NRMA meeting could post a summary/report/opinion on how the meeting went? I really wanted to go to the meeting but a last minute health issue prevented me from going.

Thanks in advance,
Paul

Just in regard to TC Chargers. My last upgrade included adding two new TC chargers. They have a new model available which is roughly half the weight and size of the old models. I bought two to fit to my car. The first problem was that the chargers have very small pin and socket fittings and the manu...

I read that report yesterday with the hope of finding out where they intended the charging stations to be located. No luck there. Am I correct in assuming that they haven't published the whereabouts of each station yet? If they haven't, are they "collecting" opinions or have they decided locations b...

Yep acceleration improved noticeably with lithiums vs lead acids. Just the weight reduction helped! Lead acids weighed about 265kgs whereas the same voltage for lithiums was just over 100kgs. Losing 160kgs of weight helped performance in every area.

Cheers

My gut feel about a 48v system is that acceleration may not be slow but embarrassingly slow. I finished my conversion in 2010 with a 96v motor and controller with 8 x 12v SLA batteries in a 1993 Suzuki Swift. Battery weight was about 260kgs. One of my regular trips was to the golf course 10km away a...

In my off grid place west of Sydney I use a Plasmatronics PL30 Regulator to control my battery bank. I am aware that this regulator is capable of charging a second battery bank or turning on lights or running irrigation pumps etc etc depending on criteria the user sets in the regulator. And the crit...

Yep Chris I had noted that with previous chargers and had tried it with this charger before I took it to my brothers place. I tested with a multimeter hooked up and got no DC output then tried it hooked up to my battery bank and still no response. But from memory with previous chargers, if I had no ...
