Re: Two chargers blow simultaneously.

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...

Re: Two chargers blow simultaneously.

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...

Two chargers blow simultaneously.

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...

Re: Solar Panel output: Rating versus Reality

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 ...

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

Re: Aux battery charging problems

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...

Re: Aux battery charging problems

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...

Re: Aux battery charging problems

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...

Re: Aux battery charging problems

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...

Re: Aux battery charging problems

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...

Aux battery charging problems

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...

Re: Prelude conversion project - some questions

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...

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...

Re: Battery pack placement

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.

Re: Battery pack placement

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...

Mine "sort of" locks in but once "locked" in they still wobble a bit. I would still be very interested in how your charger performs.

Still well short of 2kw but better than 1440w or am I missing something? The reason I am asking about the KPES charger is because I...

Re: Any info on these chargers?

Thanks EV2Go

I assume you mean that the max voltage for the 144v nominal charger being 176v and the amps being 10amps means the max draw/power would be 1760watts?

Thanks
