I played around with modifications. When I modified 374 byte 6, the estimated range value on the dash changed. Note that byte 6 is static. It never changes and OBDZero says it’s the capacity of the battery as reported by the BMU. So I multiply byte 6 and send it to the ECU. My range went to 131...

Agreed, it’s really just a matter of time. I see no technical roadblocks. Figuring out which PIDs the ECU needs is where I’m at currently. Some of these OBD programs use a lot of PIDs that the BMU doesn’t send without a request. Just taking data while driving down the road all I see is 373...

I was thinking along the same line.... maybe I'm not getting some command from the ECU to the BMU like extended packets or something and it is expecting a response. The reason I say that is because the MUT3 won't talk to the BMS at all with my bridge in place it says there is no BMS! Update...

Well, good catch. I’ll have to look at it when I get home. Maybe I truncated it somehow by accident. It was supposed to be sending both ways. Rookie mistake. Thanks Looks like that’s just a typo on the forum. It looks right in my code.

I only disconnected the wires from BMU pin 6 H and 7 L. Took those to the output of the bridge. Connected the input to the bridge to the BMU pins 6 and 7. So, BMU -- Bridge -- ECU Same code I posted before just without any bit modifications. Shouldn't be causing delays by just passing. I...

Possibly, I can see the messages on my OBD snooper. I haven't checked the rate yet. Not sure what you mean bi directional. It passes messages from the EV ECU to the BMU and from the BMU to the EV ECU if that is what you mean. I measured the resistance going to the EV ECU and to the BMU. It...

I installed the can bridge between the ev ECU and the BMU. The car will go to ready and I drove it… now it’s charging. Weird thing is I’m getting BMU CAN bus errors. The MUT won’t talk to the BMU I just get errors. I tried several different configurations with the terminating resistors. I drove...

Hello phebbler, The cells I purchased came balanced. In fact, everytime I bought cells from China they came balanced. Around 50% SOC. 3.6 or 3.7 I can remember now but they didn’t vary even by a millivolt. I just installed them and the car charged them all to 4.1v and does still charge them to...

Do you have daytime running lights? Round ones as in pic below. Need drivers side because glass is broken

Looked at data. Started at 140261 Km. Drove to 140327 Km. That’s 41 miles or 66km. The BMURemAh was 25.2 and SoC1 and 2 were 56.6%. Range shown was 33 Miles. Ending BMURemAh 0.2, SoC1 and 2 were 0.5%. Voltage was 347.9 at start and 324.9 at end. Minimum cell 3.95 start and 3.695 v end. 41-33 =...

Hey Guys, I didn't take that good of notes during the experiment but I recorded the data if anyone wants to slug through it. I will but it may be a few days. Not sure your questions are relevant to what I was trying to prove to myself. My goal was to see if the vehicle would drive after empty...

It means that the remaining range meter displayed … and I kept driving. The turtle light came on and I drove 8 more miles with no miles left on the gauge and the turtle light on. It also means that no matter what voltage the cells are at the car will stop when the remaining capacity goes to 0.1Ah.

Hey All, A little update for you. I did a range test today. I drove 8 miles after the turtle came on down to 0.3Ah at which point my power dropped significantly and then at 0.1Ah the car stopped and wouldn’t go any further. I was reading these values with OBDZero. The car just said …. For...

Found my issue with the thermistor. For some reason that I don't remember now I put a washer on this one CMU connection. Thanks to Kiev, he spotted it immediately. Apparently, the washer was on top of the trace and had shorted the thermistor. Resistance was 0.6 Ohms. I removed the washer and...

Hey Mickey, I am doing a similar project. https://myimiev.com/newsletter/47728-1708605811-81c8b44c798e150a4b83a0364aeb611f/click If you want a collaborator on developing the CAN bridge I am available.

Yes, the water pump circulates coolant while charging. Those all look like the correct thing to check. Wires and sensors first or maybe change the fluid first then wires and sensors that is if your pump is actually working but if it's charging it must be working some.

There are some mechanical differences between the LEV50's and the new cells. The LEV50 cells have drilled and tapped holes to mount the BMS boards which the new batteries do not have. I made jumper wires with ring terminals that mount to the boards and the terminals.

I believe so. I haven’t finished my posts and will cover this soon.
