Re: [Driving] Freelander EV With Gen1 Leaf electrics and EVBMW VCU

This is a copy and paste from the Outlander heater thread. Here is a quick update of the heater situation now I have it installed. It works! :D The longer version includes a minor disaster and a change in design. While testing I managed to drop some solder on the board while it was running. This cau...

Re: [Driving] Freelander EV With Gen1 Leaf electrics and EVBMW VCU

So the great news is we are back on the road again after more than two weeks major organ surgery (cabin heater) and some plastic surgery to the LV junction box. The vac boost is working a treat and so far everything else is too. The cabin heater issue was entirely self inflicted as I had the Arduino...

Re: [Driving] Freelander EV With Gen1 Leaf electrics and EVBMW VCU

I got it installed after my last post and so far so good with the vac boost. :) Of course a couple of other issues have cropped up but hopefully should be simple to sort. I know what one of them is as I had the same problem before, when I turn on the lights I hear a relay dropping so that is a simpl...

Re: [Driving] Freelander EV With Gen1 Leaf electrics and EVBMW VCU

And of course it wouldn't be an update from me if I didn't run into a problem. :oops: The brake boost started playing up so I'm having to reconfigure the vac plumbing. I had originally plumbed it with a vac sensor that was controlled by an Arduino but the setup was always a bit leaky and the pump wo...

Re: [Driving] Freelander EV With Gen1 Leaf electrics and EVBMW VCU

So today I managed to pretty much complete the LV junction box and get the car working again (spinning the motor while in neutral and charging). I made a couple of minor errors with the location of some wires but they were easily sorted and no harm done. Before connecting the battery properly I hook...

Re: Leaf Precharge Circuit: Identifying parts

7. What happens if we lose 12v to these contactors while driving? Obviously our motor loses power, but does anything get dangerous or break? I've had this as a problem and in my case either it doesn't break stuff if the contactor loses power or I was lucky. I followed Arber333's advice and connecte...

Re: Mitsubishi Outlander PHEV heater

I put up a photo earlier showing a circuit to control the heater but as mentioned we didn't like the cheap Chinese buck converter I used to bring the voltage down from 14.4V to 6V for the Arduino. As suggested by Crasbe this is a Traco power TSR 1-2450 5V step down voltage regulator that is designed...

Re: [Driving] Freelander EV With Gen1 Leaf electrics and EVBMW VCU

I haven't done much to the car last couple of weeks except drive it as I got some work replacing Routers in Post Offices so kinda tired at night.

I did manage to edit a video that was made a couple of weeks ago so here you go.

Re: Mitsubishi Outlander PHEV heater

You could simply set the Buck converter to 5V and connect it's output to the +5V pin of the Arduino Nano instead of the VIN pin. That bypasses the internal LDO completely. That would be the better strategy anyway, because 6V is right on the edge of the permissible input voltage. The dropout voltage...

Re: Mitsubishi Outlander PHEV heater

Digikey, Mouser, Farnell etc are great for bigger orders but for small orders charge a lot for delivery and handling.
I found the same one on Ebay for a similar price but less for postage.

Re: Mitsubishi Outlander PHEV heater

Sorry guys I somehow managed to unsubscribe from the topic and missed your replies.

So the consensus is Arduino's don't like 14.4V and cheap Chinese buck converters may not be reliable. I'm not surprised at the answers so will follow your advice and come up with a better solution.

Re: [Driving] Freelander EV With Gen1 Leaf electrics and EVBMW VCU

Last couple of weeks I've been working on getting a heater for the cabin. I've been on the Mitsubishi Phev heater thread and finally got some heat.
Here is a link to the thread.

Now I need to gather up the inclination to install it.

Re: Mitsubishi Outlander PHEV heater

I used some vero board to make this a bit more robust. IMG_20240210_134259946.jpg IMG_20240210_134330876.jpg I also added a buck converter to lower the voltage to around 6V as I wasn't sure the Nano would be happy with 14.4V. What are your thoughts on this guys and should I do the same for the Due a...

Re: Mitsubishi Outlander PHEV heater

Physics says air is not a good medium to transpost heat. It was just a thought that the casing of the Outlander heater gets very hot and all this heat is wasted so if we could scavenge even a little by simply diverting the intake for the HVAC it might be worth doing. In my case I have a lot of work...

Re: Mitsubishi Outlander PHEV heater

I was thinking of feeding the air that goes into the cabin over the coolant heater. That way the air would be warmed a little even before it reached the heater matrix as the casing for it gets very warm. I suspect putting the outlander heater into a box so all the hot air could be drawn into the cab...
