Re: Insuring a conversion in the UK

Phoned Adrian Flux today to get a price on the MG. Just said it was a modified MG F to start with and specified electric motor when they asked about details. They didn't seem that phased by it. Didn't ask about power output of the motor etc. What they did ask about felt like more the phone operator ...

Re: Mechanical design database wiki page: please contribute

Great idea! I've wanted to find a sensible place to upload some of the 3d print parts I've designed for the Prus Gen 2 inverter. I added those plus the outlander motor part I designed a while back.

Re: MG F - Outlander Rear differential with Prius Gen 2 Inverter.

I'm really interested to see how you get on with the Outlander charger as I'm struggling to get my Gen 1 Leaf charger working. It's really easy to get working. There is plenty of code around to butcher so it doesn't take much coding skill to get charging initially. I think there will be a bit of ex...

Re: MG F - Outlander Rear differential with Prius Gen 2 Inverter.

Bench testing is now complete for a second time! Thanks to RStevens for the teensy 3.6, they are pretty hard to get hold of these days. So I was looking at a VCU redesign if I couldn't get one. Will try not to kill this one! Outlander charger and dc-dc is really easy to use. Just needs canbus for th...

Re: Mitsubishi outlander charger and DC:DC

Got this charging my 60s pack on the bench at 220v. Getting around 8.8 Amps. Here is the code I used just to add to the pool. Using a Teensy 3.6. Batmax can be removed, I just use that as a safety to stop charging once one cell reaches a certain voltage. I will refine it further. But this puts charg...

Re: MG F - Outlander Rear differential with Prius Gen 2 Inverter.

From what I understand you are allowed to structurally weld/fix if you are rebuilding/restoring back to original - like cutting out a rusty/damaged spare wheel well and restoring back to original, so for you I would think it is fine. What is not allowed is modifying away from the original design - ...

Re: MG F - Outlander Rear differential with Prius Gen 2 Inverter.

So a bit of a change in plans in the last week. Last week I killed my Teensy based VCU in a Prius charging test incident. I decided to ditch the Prius inverter for charging and picked up an Outlander Charger/DC-DC. Got it talking on the bench and have updated the VCU code to run the Charger. I can r...

Re: UK IVA Modifications

Oh yeah that might sting me as well since I cut out the very flimsy spare boot compartment in the front of the MG. I was hoping since it was not structural at all I would get away with it. From what I have heard these days the DVLA are sending out someone to check the car over. So it's up to the per...

Re: Prius Gen2 Adapter Board for CHARGING

I think I'm going to give up on the charging side of this. It didn't seem to be able to push that much power into the inverter and there are allot more options available now in terms of OEM modules than there were two years ago when I started. I have the space for a charger anyway.

Re: Prius Gen2 Adapter Board for CHARGING

Think I may have broken something. Went to charge the battery up a little today and it flipped the RCD and also the Earth fault breaker. Killed my teensy VCU so I won't be doing any thing meaningful until I get that replaced. Thinking I might go for an Arduino Due next time, teensy seems a little de...

Re: Prius Gen2 Adapter Board for CHARGING

My VCU waits for 3 seconds on start up before going through the charge or run loop. I'm guessing this gives the adaptor board time to wake up. Currently if I want to charge I will power up the adaptor board alone and switch to buck mode, power off and then power on everything at the same time. I did...

Re: Prius Gen2 Adapter Board for CHARGING

I never really got much sense out of the il1 and il2 readings, I am pretty sure I calibrated for MG2 back when I first got the inverter. I use the ISA shunt for my current reading since that seems to be pretty accurate and it's already on the canbus. I have the mains input on the two outer phase con...

Re: Prius Gen2 Adapter Board for CHARGING

As far as I know UDC is the High Voltage bus in the inverter, this is after the buck/boost converter so separate from the battery inputs. The battery inputs share the negative busbar. However you should notice that the positive bus bar from the battery inputs go into the converter and is not connect...

Re: Prius Gen2 Adapter Board for CHARGING

Sorry I wasn't very clear on my setup. My contactors are controlled a separate Teensy based VCU I designed and coded. It takes the inputs signals from the inverter control board and then activates the contactors based on that. The idea was that I could add in additional safeguard checks before closi...

Re: Prius Gen2 Adapter Board for CHARGING

When I tripped the mains it was because when I added in the second battery contactor for charging or driving I forgot to change the code. So I was closing both contactors, shorting battery input positive and the HV bus positive.
Which could have gone worse.

Re: MG F - Outlander Rear differential with Prius Gen 2 Inverter.

I like how there's 5 switches to turn it on. That little control board has been really handy! I used it when I was testing the motor to control the inverter VCU and inputs manually. This time I used it to separate out the inverter, inverter VCU, my VCU, contactors and BMS stuff. Quite helpful when ...

Re: MG F - Outlander Rear differential with Prius Gen 2 Inverter.

Bench testing is now pretty much complete. Ended up dropping the battery down to 60s to make installation into the car easier, also means I can charge to 100% as at 80s the Prius inverter couldn't reach max battery voltage through bucking mains AC. I think a future upgrade will be an OEM charging sy...
