This is a short list of stuff you need for upgrading Ford Ranger EV battery. BOM: (RECOMMENDED:) Ford Ranger EV Ranger replacement inverter board. Serial interface and comm. program (Johannes H. ESP wifi module) Any lithium battery pack min 100V, max 400V. (Tesla Model S 60/75kWh) BMS (Simp BMS for ...

Some of it means. Be aware of the treacherous ice.
Could look very thick an solid, but very thin some places, because of the currents.

If a black cat just crossed your path, you should be extra aware!?

Looks great.
Do you have the PCB layout ready tonight, or do I have to wait for tomorrow.

Its a little different use of components, don't you want to use the same design as Ti?

Did you use this document for ref?

Ref. ver 3 board and EVSE.

I use the OUT1 to activate HV DC charge contactor, and it works.
And I don't have precharge for the DC charge contactor.

Is it okay to do it this way?

It's very interesting, have read it, don't get me wrong! But if you think "normal" use of an EV, in cold winter climate: Charging, maybe in a garage, over night, with in car heatpump. And structured work time departure. If you park outside at work, without charging, then you must rely on g...

Thinking outside the box = Johannes H. I love it! But you will not get any less energy consumption, than using any other resistance heating. And the uncertainty of battery health at low temperatures. That's maybe why EV manufacturer don't use this. And if the car already has heatpump, it would be du...

Thank you, I'm a little old school, and like to have everything in one drawing...... The motor temp sensor is KTY84, it's about 5C to high. Don't know why. But the temp sensors on the Ford (Siemens) motor often read to high temp. But the Ranger EV is 20 years now. The temp sensor in the inverter mus...

That is great.
But a device like this must have CAN!
Have used the Leonardo from hobbytronics, very useful, for simple CAN projects.
But there may be other "simple" microcontrollers with CAN support?

No offence taken, negative feedback is the the most positive feedback..... :D On charger DC side, I only get 0.3A @300V at PSU power on. Have not tested with scope, maybe I should, to get faster measurement. I had precharge on the DC side, but Damien wrote "charger has built in precharge, no ne...

Have been looking for a isolation monitor for my EV projects, for many years actually. Most ready build systems are expensive: https://www.bender.de/en/products/insulation-monitoring/isometer_ir155-3203ir155-3204 http://www.sendyne.com/Products/SIM100%20Isolation%20Monitor.html Found this reference ...

Hi Tom. Have checked my connections and diagram, and cannot find anything wrong. I was just thinking it was a good idea to have charger controlling the charge contactor. And the inverter controlling the inverter contactor. It works, just plug in and charging starts. (and stops) https://www.youtube.c...

Hello Tom. This is my setup for now. I use the pos contactor and precharge ouput from your BMS to engange the AUX high volt (DC/DC, battery heat/cool) The charger engage the pos charge contactor. And the inverter engage the precharge and contactor for inverter. When I open charge door and plug in, t...

Here is schematic of the board ver. 15a

Files moved to first post!!!!!

Yes will do that, this is only first prototype. Have only made 5.
We are five people testing this out now.
I'm currently out of stock.
So I will order more boards very soon.
I guess there will be enormous demand for this fantastic product

The Ford Ranger is a factory build Electric pickup vehicle. Year 1999-2001. The lifetime of NiMh are very good, but many of these trucks would need new batteries. There is not any good solution for upgrading to new battery chemistries. Because the factory inverter, BCM (It's the BMS) and other modul...

Here I will try to give some information on the "perfect" marriage between Tesla battery and charger, Simp BMS , and the Inveter. Have also made an "main" ecu with display, that will control/talk to inverter, charger, BMS and instrument cluster via CAN. Will try to update this fi...

Welcome to the ford Ranger inverter board support. Will update this first post with relevant information. Please read all post in the Ranger section, before click "buy now" There is also lots of general info about the openinverter in the rest of the forum and Wiki Files listed at end of th...

It's working:
I now get 23.8AAC reported from the EVSE!!!!
The manual says "Set the CAN mode to Master by sending '31'"
It should be 30 off. (if you have single charger)

But I still get some jumping down to 14AAC every few seconds, is that normal?

Did a second test today. same problem no more than 12AAC, Module Cur Request will not go over 3900?? Same setup, battery pack is 303VDC (rise 1V while charging) 6 - DC Charge Voltage : 330V 7 - AC Current Limit : 20A t - termination voltage : 345V Module Cur Request: 3333 when I set lim 10A Module C...

Aha got it Tanks, a little confusing because of the "termination voltage"

Hi, just got my charger set up for testing. And can't get the AMP up over 12AAC (7.5ADC) total for all modules. Have read all post on the old forum, and are of the impression that you could set any AMP in the setting, because the EVSE will have the last word? Have set the menu "7" to 5, 10...
