That's the thing, quite a lot. Not so much off-throttle but brake blending regen up to 40% of acceleration torque.


Hm... this is why i prefer to have only off throttle regen. Maybe 10kW at 50km/h and 40kW at 120km/h. Brake system i prefer to keep mechanical since there is still ABS and other ...

surprised you didnt op to put the leaf gearbox in, but i guess this is now just mechanic work, rather than a "project"


On Mazda i replaced tramsmission with Mitsu gearbox and put it to fabricated mounts. In the end i needed to reweld the 3rd mount as the mounting plate was cracked because of ...

....
As arber suggested a lot of metal was in the oil. Did we use the wrong oil? Did we not fill up all the way? Or is the gear box just old? Who knows. This time I know I need to get 2.5l in there and the oil came with the gear box.

While at it I also inspected the shaft coupler and splines and ...

Really impressive build!
When I was converting my Mazda MX-3 i came across some people trying to convert Miata MX-5. I think from Australia. We had a debate about Mazda using transmission as a carrying member against chassis twisting in the turns. That would explain the lightness of the chassis ...

hm... I remember from using jk bms you could only set start of balancing from 3v or 3.2v.
I also tried to set it higher than 3.6v but it wouldn't go...

No need for CAN or coms at the moment.

I'm currently attempting to get them to activate balancing while the cells are at lower voltages (2.7-2.8v). I've been adjusting equalization settings this eve and balancing still will not active. I can take screenshots of what it has.


I think you ...

What is your question? Do you need CAN protocol?
Look for JK BMS posts here...

So I finally did some more diag and found that my 100W 50ohm precharge resistor was blown. This was after many, many starts. I initially replaced with 100W 100ohm resistors and realized I was going the wrong way as they blew as soon as I turned the system on (again never got out of precharge).
I ...

I am using ZEVA BMS boards in my car for some time now and i am really satisfied. Works great now.
There is a subtle problem i would like to resolve...

Yesterday when i tried to balance my cells in the front box of my Megane EV ( https://evmeganetech.wordpress.com/ ) i saw the cell values i read ...

Hello, does anyone have a view on whether the Outlander rear inverter can be used upside ways or upside down? Space is tight and I’m trying to evaluate all options.


I tried horizontal and vertical mounting and both work very well. Didnt try inverted though...
It doesn't have moving parts so I ...

Out of curiosity i went and weighed all different components i had here.
Results...

Outlander OBC and DCDC weighs 12kg
Outlander Heater weighs 3,5kg
Outlander AC compressor weighs 6,5kg

Tesla gen2 charger weighs 16kg!!! Surprisingly low for such a bulky item
Tesla DCDC weighs 3,3kg

Volt gen2 ...

I was thinking on some failure modes for transmission diff section....

Contaminated gearbox oil (or lack of oil).
Grinding due to insufficient lubrication.
Vibration from increased friction and heat.
Drain and inspect oil for metal shavings or burnt smell.

Worn differential bearings
Grinding ...

I also let the car coast down our steep road with tranny in neutral i.e. motor out of the loop. Same noise.

Looks like the differential gears. Do you have any torque available for return drive upslope?

What happens if you fix one wheel to the ground and keep the other one up and ...

@chentron:
Yesterday when i tried to balance my cells in the front box of Megane i saw the cell values i read with my Multimeter were 0.03V higher than those values i read in BMS display. 4.09V vs 4.063V that BMS showed! I would like to recalibrate my BMS modules.
I read somewhere that ZEVA 24BMS ...

What charger do people recommend to keep the modules charged up while I do all the work? It's going to take me a few months, so I don't want to let them fully discharge...

You mean like a simple 360Vdc charger?
You can use chevy Volt charger. It can be simply controlled by PWM signal ...

I also noticed a small difference from replacing inverters. Newer ones give more torque.

Today i went to replace the inverter to test if newer had more torque.
I removed the cables and inverter itself. I replaced my older inverter P/N 9410A081 with newer model P/N 9410A163 from 2020. After a ...

Another news...
I got Megane to garage and managed to make some repairs and corrections.
First i foiund the tiny coolant leak that left a stain n my driveway... it was hidden in hoses under the bumber. I simply used a good hose clamp.
Second, as i was at the hoses i released coolant and removed the ...

Hello,
has anyone done anything on using H2 fuel cell in EV conversions? ....


I wouldn't recommend that kind of project to an ordinary Joe. it is full of hazards and H2 can go bang...
Earth atmosphere with O2 is not a good pace for H2 cells use...

I would rather recommend you look at methanol ...

DOH!
I just found out the RH brake light doesnt work... but the LH and central brake light are both fine.... when i tested the light bulb it was fine.
Then i went to test both ends of the wire...AND of course i wouldnt get any signal there!!! This means a broken wire! I didnt even try to find the ...

I took the liberty of just adding thge top line in the Nissan Leaf inverter page on the wiki.
https://openinverter.org/wiki/Nissan_Leaf_inverter
I never tested if 180Vdc is truly the minimum voltage for Leaf inverter, i guess i trust Damien... because he s doing it wrong!

Here you can find the files for the RPM speedo board
I was mashing it together at the time so i didnt make a schematic, just the board.
Components are all in the PCB file.

It's working ! Thank you.

Now, what kind of circuitry would it take to convert the same TachoOut PWM signal into a signal (Si) suitable for the Speedometer?
....


Not the same signal, rather use what is there...
See here how i did it for my Mazda
https://mazdamx3ev.wordpress.com/2015/07/03 ...

I made my own design now with the same form and signal pinout in mind. That way if i would replace first VCU with my board the thing would directly work with the teensy chip and cable harness. The only difference would be the new expanded input, output pins with two new analog pins.

After i ...

I am going to try with an inline capacitor.


Ok what car are we talking about? Give me more data about type, engine and chassis form.

I found your Toyota Supra 1985 reference. What kind of engine did it have? I ask because tacho pickup could be from coil or from ECU...
Speedo is just toothed ...
