Re: Prelude conversion project - some questions

I don't know either - all I know is that the ZEVA wasn't giving an isolation error before it blew, and now it does. I never saw the current exceed 180 amps, but it's possible that it had been 'singed' at some point driving up the hill and the big bump might have weakened it? But I still had power as...

Re: Prelude conversion project - some questions

Now that the charger can charge the car, I decided to bypass the master precharge delay and charge the car fully. The Enable feature stopped the charge as soon as the first cell exceeded 4.2 V, which is good. Since the car was driving so I figured, before I go and immobilise the thing for a few week...

Re: Prelude conversion project - some questions

No, this is still with the original Enable-only charger. I have put a failsafe relay on the Enable line so it will disconnect the charger once a cell goes high, but this is only a stopgap until the new charger arrives. However my goal this weekend is to install the new battery floor with provision f...

Re: Prelude conversion project - some questions

The charger works now! I wanted to move the car, so I got in, powered up, pressed the throttle and it dropped out. Repeat, same thing... Aha! The master contactor isn't closing! The master precharge relay was closing, but it was trying to pass big voltages across a 200 R resistor inside the pack. No...

Deliveries are happening in Perth. I gave a talk to the Mosman Park Men's Shed about Li-ion batteries (same one I gave at the expo in Brisbane) and this showed up :)

Re: Prelude conversion project - some questions

Good news coulomb the CAN controlled charger should be here by next Friday. I'm torn now - do I get the car going on 6 modules so we can get it over the pits sooner? And risk the charger not working again, and DoT taking issue with the battery pack floor's occasional oscillations? Or do I hack the c...

Re: Cooling chargers?

I'm often surprised when folks will install an air-cooled TC charger directly underneath the hood of the car, or buried deep inside the boot. These things get seriously hot! The fan should work well, just be aware of any dust accumulation. It might not be that difficult to cut a couple of sections o...

Re: Prelude conversion project - some questions

I think this will be the least worst way of running coolant through the pack. The return line need not go back through the main battery pack, but it will be a bit neater. The gap between them is about 900 mm, and the axle and 4-wheel steering unit are right in between.

Re: Prelude conversion project - some questions

Yes the new charger is being assembled while I wait. It will be good to be able to decrease the power to suit a 10 or 15 A socket, but as I've covered before, the extra voltage is worth adding if I can. It's just a bugger to fit. If the new charger would get here sooner I'd install it and just get t...

No not yet, but I hope to have the 60 Ah cells very shortly.

Re: Prelude conversion project - some questions

Okay I might have some insight into the charger problem. I jury-rigged a solution using one of my 2 kW chargers I use to charge the race bike. These are designed for charging 84 cells in series, up to a Vmax of 350 V. So higher than that of the current Prelude battery at 72 cells, but not so far awa...

OK some more diagnostics. I put the sixth and final pin in the TC charger plug and ran it out for measurement.

Re: Prelude conversion project - some questions

Well I plugged the Type-2 connector from the OpenEVSE and looked at the charger: red-red-green-green... I connected D and F and it briefly caused the pumps to change pitch (suggesting some fluctuation on the 12 V system) and the charger changed to red-red-red-red... Before reverting to reg-green-red...

Re: Prelude conversion project - some questions

Yes, the AVC2 is indeed still connected with all of this. I had assumed that the AVC2 had a diode and relevant resistors in there to start with... otherwise, what's the point of it?

I will troubleshoot the TC charger tomorrow morning when I'm fresh. Not a good idea to persist right now.

Re: Prelude conversion project - some questions

I tried to change the resistor arrangement as per the Modular EV Power website's suggestions. I was plugging Richard's Open EVSE in. Putting a 880 R resistor between pilot Earth and ground caused a 'ventilation error'. Putting a 1.3kR resistor between pilot Earth and ground caused a 'diode error'. P...

Re: Prelude conversion project - some questions

Which is why I think it works best with Type-1 and not with Type-2. Perhaps a delay of some kind is needed for Type-2?
