Nice unit.
Can it blow air out of the case? How do you make sure no water gets in?

I plan to route the air ducts under the hood or into the trunk

the seam is not heated up enough, there is no need to rush.

2. Other relay will show active signal on pin_8 and activate charging process. This one is tricky as it will also power hydro pump of the power steering. A bit annoying to hear this with charging... I will have to think about how to use a single relay to sense PP and command charging and second rel...

I have such a fan installed inside the battery case.

OK now i changed from tone to PWM code and it works...sort of :?. I still get needle to jump by 10km/h. This lets me to belive the problem is not in the code but rather in the CAN bus rutine or chip. It seems like inverter report does not arrive to VCU in time and so speedo is not updated fast enou...

Request BMS

The tone function has another parameter: pulse duration. tone(pin, frequency, duration) And also in your code, line 2026 "tone(OUT9, 3000); " what is it for? You need to enable hardware PWM. The code already contains the library #include "Teensy_PWM.h" frequency = 10000.0f; PWM_I...

I have 84S cells as well. But i use 7 BMS modules. Each BMS module is connected to 12S battery module as this was the easiest. When i connect to CAN lines i can see the FF request going out and i see all 7 modules reporting on the line. Everything is good on the lines but VCU does not read the tele...

Are certain BMSs not included in the array, or is data from one BMS partially missing?
I only use data from cells that are not repeated in the array.
I have an 84 cell battery, 4 pieces of BMS.

Tnx i will look into why i cant get any traffic on the lines... On the other hand i see very little torque in reverse. Today i tested this driving in a small hill. It was embarrasing :(. How to up this a little? I also have little torque in reverse. Probably here BMS_keyOn = 1; // enable the invert...

Now finally everything works as it should with VCU. I got good acceleration, good regen response, Nice reverse drive and everything connected to Outlander components is operating aas it should. Acceleration at 13s now. I managed 11s with large torque swings, but it was not comfortable. I setup all ...

My engine is also installed in the opposite direction. Everything works fine. When I changed the direction of rotation, my engine stopped accelerating spontaneously.

I have an inverter 9410A067

My power comes either from the ignition switch, or the relay from the charging pistol is switched on through an optocoupler.

I already did that. pin40 is drawing too much power and not reacting to analog input. I had to cut traces to pin40 and replaced it with pin39. In my haste i managed to damage trace to pin41 as well and so i enhanced that line as well. Now when i connect throttle i get a good singal to calibrate fro...

The electric amplifier communicates with the dashboard all the time. Message to the dashboard: 5E4 3 00 02 00 If the ESD is activated in the dashboard, then this message turns off the indicator. The sending frequency is approximately 200ms. For EUR from KIA Cerato 3 There is a different message ID. ...

I also first tried to run the electric hydraulic booster on Mercedes W168, but then I installed an electric booster from KIA CEED. Energy consumption is much less, there is no noise at all, and it is controlled via the canbus perfectly.

According to the datasheet, the maximum current of ULN2803A is 0.5A, with a parallel connection of 1A. The contactor has a starting current of up to 4A, I think you should not exceed the maximum current.

Customized the dashboard based on the recorder from aliexpress

I recently used this service https://shopfans.ru/

Tnx for the info. Can you tell if you used additional pullup resistor with the fan? I want to know if the ULN2803A output is direct GND sink or does it output 12V? tnx. The fan PWM is controlled at a low level, I simply connected the VCU output to the input of the fan control unit. For other purpos...
